1 year ago Wags the dog was 3 years more than 3 times the age of Scratch’s the cat. In the 2 years time Scratch will be 2 more than one quarter of Wags age. Find Wags and Scratch’s approximate ages today?

Answers

Answer 1

After solving the problem we found that Wags is approximately 15 years old and Scratch is approximately 5 years old today.

The solution uses algebraic equations and substitution to solve for the ages of Wags and Scratch, which is based on the concept of solving systems of linear equations.

Let's assume that Wag's age today is represented by W, and Scratch's age today is represented by S.

From the first piece of information, we can set up the following equation:

W - 1 = 3 + 3(S - 1)

Simplifying:

W - 1 = 3S - 6

W = 3S - 5

From the second piece of information, we can set up the following equation:

S + 2 = (1/4)(W + 2) + 2

Simplifying:

S + 2 = (1/4)W + 2.5

Substituting W = 3S - 5:

S + 2 = (1/4)(3S - 5) + 2.5

Solving for S:

S + 2 = (3/4)S - (5/4) + 2.5

S + 2 = (3/4)S + 3/4

1/4 S = 1 1/4

S = 5

Substituting S = 5 into W = 3S - 5:

W = 10 + 5

W = 15

Therefore, Wags is approximately 15 years old and Scratch is approximately 5 years old today.

Carrie can bicycle 24 miles in the same time as it takes her to walk 6 miles. She can ride 9 mph faster than she can walk. How fast can she walk?

Answers

Carrie can walk at a speed of 3 mph.

To find out how fast Carrie can walk, we can use the formula distance = speed × time. Let's call the speed at which Carrie walks x, and the time it takes her to walk 6 miles t.

Since she can ride 9 mph faster than she can walk, her biking speed will be x + 9. We can set up the following equations:

6 = x × t (for walking)
24 = (x + 9) × t (for biking)

Since the time it takes her to walk 6 miles and bike 24 miles is the same, we can set the two equations equal to each other:

x × t = (x + 9) × t

Simplifying the equation gives us:

x = x + 9

Subtracting x from both sides gives us:

0 = 9

This is not a valid solution, so we need to go back to our original equations and solve for t:

t = 6/x (for walking)
t = 24/(x + 9) (for biking)

Setting these two equations equal to each other gives us:

6/x = 24/(x + 9)

Cross-multiplying gives us:

6(x + 9) = 24x

Distributing the 6 gives us:

6x + 54 = 24x

Subtracting 6x from both sides gives us:

54 = 18x

Dividing by 18 gives us:

x = 3

So Carrie can walk 3 mph.

Answers

The function values.

To evaluate the function g(x) = 8 - x / 8 + 7 at the indicated values, we need to substitute the values into the function and simplify.

g(2) = 8 - 2 / 8 + 7 = 6 / 15 = 2 / 5

g(-8) = 8 - (-8) / 8 + 7 = 16 / 15 = 16 / 15

g(1/2) = 8 - (1/2) / 8 + 7 = (15.5) / 15 = 31 / 30

g(a) = 8 - a / 8 + 7 = (15 - a) / 15

g(a - 8) = 8 - (a - 8) / 8 + 7 = (16 - a) / 15

g(x^2 - 8) = 8 - (x^2 - 8) / 8 + 7 = (16 - x^2) / 15

So, the function values are:
g(2) = 2 / 5
g(-8) = 16 / 15
g(1/2) = 31 / 30
g(a) = (15 - a) / 15
g(a - 8) = (16 - a) / 15

Answers

Step By Step Explanation

Filled jar = ?

How much poured or (x) = 350ml × 8 glasses

=2800 ml

How much left or (y) = 200ml

Capacity = How much poured + How much left

Capacity = x + y

Capacity = 2800 ml + 200 ml

Capacity = 3000ml

Give answer in litres

1 litre = 1000 millilitre

So 3000ml = 3000 ÷ 1000

So 3000 ml = 3 litres

Capacity = 3 litres

Let X (3, 0.02). Given Tx = 300 calculated by the Esscher Premium Principle with parameter 1, calculate h

Answers

The value of h is 99.969.

The Esscher Premium Principle is a method of calculating insurance premiums that considers the risk of an event occurring and the potential severity of the loss. The formula for the Esscher Premium Principle is:

Ex = ln(∑eαx Px)/α

Where Ex is the Esscher premium, α is the parameter, x is the loss amount, and Px is the probability of the loss occurring.

In this case, we are given X (3, 0.02), meaning that the loss amount is 3 and the probability of the loss occurring is 0.02. We are also given that the Esscher premium is 300 and the parameter is 1. Plugging these values into the formula, we get:

300 = ln(∑e1(3) 0.02)/1

Simplifying the equation, we get:

300 = ln(0.02e3)

Taking the natural logarithm of both sides, we get:

e300 = 0.02e3

Dividing both sides by 0.02, we get:

e300/0.02 = e3

Taking the natural logarithm of both sides again, we get:

300 - ln(0.02) = 3

Solving for h, we get:

h = (300 - ln(0.02))/3

h = 99.969

Therefore, the value of h is 99.969.

How many solutions does the system have?{ 2 x + 3 y =-6 3 x − 4 y = − 12

Answers

Therefore , the solution of the given problem of equation comes out to be which is (x, y) = (-60/17, 58/17).

How do mathematics equation work?

The same letter is frequently used in mathematical formulas to attempt to enforce unity between two claims. Mathematical expression equations, also referred to as assertions, are used to demonstrate the equality of many academic figures. Using y + 6 = 12 like an example, the normalise separates 12 but rather b + 6 in to the two pieces. The relationship between each sign variable and the amount of lines can be identified. A symbol's meaning typically runs counter to itself.

Here,

Elimination is one approach that could be used to solve the problem. So that the component of y in each equation is -12, we can do this by multiplying the first equation by 4 and the second equation by 3:

=> 4(2x + 3y = -6) -> 8x + 12y = -24

=> 3(3x - 4y = -12) -> 9x - 12y = -36

The two formulae combined give us:

=> 8x + 12y + 9x - 12y = -24 - 36

=> 17x = -60

=>x = -60/17

We can find y by substituting x into either equation:

=> 2(-60/17) + 3y = -6

=> 3(-60/17) - 4y = -12

When we simplify each solution, we obtain:

=> -120/17 + 3y = -6

=>-180/17 - 4y = -12

By y in each solution and solving, we obtain:

=> 3y = 174/17

=> y = 58/17

As a result, there is only one solution to the system, which is (x, y) = (-60/17, 58/17).

Answers

The equation that represents a linear function rule for the following set of ordered pairs is  A. y = -3x + 2

How can the equation that represents a linear function rulebe determined?

We can express the Equation of a linear function, as y = mx + b.

m= slope

b= y-intercept

We can determine the slope (m):

= (change in y)/(change in x )

then we can substitute the values as :

= (-7 -(-4)) / (3 - 2)

= -3/1

= -3

Then thevalue of b can be found through the substituting of  m = -3  into the  equation knowing that  (1, -1) = (x, y)

Then we have;

-1 = [-3(1) + b]

-1 = [-3 + b]

[-1 + 3] = b

b = 2

In this case ,  we can put m = -3 , b = 2

y = mx + b

y = [-3(x) + 2]

Therefore, we have

y = -3x + 2

3 gallons are the starting value determined by the slope-intercept relation.

What is slope intercept form?

One of the most popular ways to represent a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfils.

To determine how much gas is entering his car each second, we must determine the rate of change:

Rise / Run is the rate of change.

Rate of change: (11 - 3 - 11) / (48 - 0)

Change rate: 8/48 = 1/6 gallons

Making use of the slope-intercept relationship:

Y = b(x) + c(slope); c(initial gas amount)

Choose any (x, y) point pair on the table:

(0, 3)

3 = 1/6x + c 3 = 1/6(0) + c\s3 = 0 + c\sc = 3

Select the graph of the solution set that would represent the following expression. 3(x - 2) = 5(x + 1)

Answers

Answer:

Step-by-step explanation:

To graph the equation 3(x - 2) = 5(x + 1), we can first simplify it by expanding the brackets:

3x - 6 = 5x + 5

Next, we can isolate the variable on one side of the equation. We can do this by subtracting 3x from both sides and adding 6 to both sides:

-11 = 2x

x = -11/2

Now we have the x-coordinate of the point where the graph of the equation intersects the x-axis. To find the y-coordinate of this point, we can substitute x = -11/2 into one of the original equations and solve for y:

3(x - 2) = 5(x + 1)

3(-11/2 - 2) = 5(-11/2 + 1)

-33/2 - 6 = -55/2 + 5

-33/2 - 6 + 55/2 = 5

-33/2 + 44/2 = 5

11/2 = 5

What is length?

Length is a term used to describe the magnitude of a line, distance, or size. It usually refers to the measurement of something from end to end, such as the length of a river, the height of a building, or the size of a piece of fabric. Length is typically measured in units such as feet, meters, or even inches. It is an important concept in science, engineering, and mathematics. Length helps us to understand and quantify the size of objects and the space they occupy.

We can find the volume of any three dimensional object by using the formula V = l x w x h, where V is the volume, l is the length of the object, w is the width, and h is the height. This formula is applicable to all three dimensional shapes, including cubes, rectangles, prisms, cylinders, and so on.

To find the volume of a cylinder, we use the formula V = π x r² x h. Here, V is the volume, π is the constant pi, r is the radius of the cylinder, and h is the height. To find the volume of a sphere, we use the formula V = 4/3 x π x r³. Here, V is the volume, π is the constant pi, and r is the radius of the sphere.

We can also use volume to measure liquids or gases. We measure liquids in liters or milliliters, and gases in cubic meters or cubic feet. For example, 1 liter of water is the same as 1,000 milliliters of water.

Volume is an important concept in mathematics and is used to measure many different things. It is used to measure the size of objects, the volume of liquids and gases, and the amount of three dimensional space something occupies.

Hoped this helped

Answer:

To find the 20th term of the sequence 1, 3, 9, 27, we need to first identify the pattern of the sequence. It appears that each term of the sequence is obtained by multiplying the previous term by 3. This means that the sequence is a geometric sequence with first term (a) = 1 and common ratio (r) = 3.

Using the formula for the nth term of a geometric sequence:

an = a * r^(n-1)

where an is the nth term of the sequence, a is the first term, r is the common ratio, and n is the term number.

Substituting the values we have:

a = 1, r = 3, and n = 20

an = 1 * 3^(20-1) = 1 * 3^19 = 1162261467

Therefore, the 20th term of the sequence 1, 3, 9, 27 is 1162261467.

2. (4 marks) Find a basis for \( \mathbb{R}^{4} \) containing \( v=(1,-1,1,-1), \quad w=(0,1,0,1) \).

Answers

A basis for \( \mathbb{R}^{4} \) containing \( v \) and \( w \) is \( \{v, w, e_{1}, e_{2}\} = \{(1,-1,1,-1), (0,1,0,1), (1,0,0,0), (0,1,0,0)\} \).

A basis for \( \mathbb{R}^{4} \) is a set of four linearly independent vectors that span \( \mathbb{R}^{4} \). We are given two vectors \( v=(1,-1,1,-1) \) and \( w=(0,1,0,1) \) that are part of the basis. To find the other two vectors, we can use the standard basis vectors \( e_{1}=(1,0,0,0) \) and \( e_{2}=(0,1,0,0) \) and check if they are linearly independent with \( v \) and \( w \).

First, we check if \( e_{1} \) is linearly independent with \( v \) and \( w \). We can do this by setting up the equation \( a_{1}v + a_{2}w + a_{3}e_{1} = 0 \) and solving for the coefficients \( a_{1}, a_{2}, \) and \( a_{3} \).

\( a_{1}(1,-1,1,-1) + a_{2}(0,1,0,1) + a_{3}(1,0,0,0) = (0,0,0,0) \)

This gives us the system of equations:

\( a_{1} + a_{3} = 0 \)

\( -a_{1} + a_{2} = 0 \)

\( a_{1} = 0 \)

\( -a_{1} + a_{2} = 0 \)

We can see that the only solution is \( a_{1}=a_{2}=a_{3}=0 \), which means that \( e_{1} \) is linearly independent with \( v \) and \( w \).

Next, we check if \( e_{2} \) is linearly independent with \( v \), \( w \), and \( e_{1} \) by setting up the equation \( a_{1}v + a_{2}w + a_{3}e_{1} + a_{4}e_{2} = 0 \) and solving for the coefficients \( a_{1}, a_{2}, a_{3}, \) and \( a_{4} \).

\( a_{1}(1,-1,1,-1) + a_{2}(0,1,0,1) + a_{3}(1,0,0,0) + a_{4}(0,1,0,0) = (0,0,0,0) \)

This gives us the system of equations:

\( a_{1} + a_{3} = 0 \)

\( -a_{1} + a_{2} + a_{4} = 0 \)

\( a_{1} = 0 \)

\( -a_{1} + a_{2} = 0 \)

Again, we can see that the only solution is \( a_{1}=a_{2}=a_{3}=a_{4}=0 \), which means that \( e_{2} \) is linearly independent with \( v \), \( w \), and \( e_{1} \).

Therefore, a basis for \( \mathbb{R}^{4} \) containing \( v \) and \( w \) is \( \{v, w, e_{1}, e_{2}\} = \{(1,-1,1,-1), (0,1,0,1), (1,0,0,0), (0,1,0,0)\} \).

According to the given equation, a+x=b+y=c+z+1, where a,b,c,x,y, z are non-zero distinct real numbers, we can rearrange the equation to find the value of one of the variables in terms of the others. For example, we can rearrange the equation to find the value of x in terms of the other variables:

x = b+y-a = c+z+1-a

Similarly, we can rearrange the equation to find the value of y and z in terms of the other variables:

y = a+x-b = c+z+1-b

z = a+x-c-1 = b+y-c-1

Now, we can substitute these values into the given matrix to find the value of each element:

[[x,a+y,x+a],[y,b+y,y+b],[z,c+y,z+c]] = [[b+y-a,a+x-b,c+z+1-a],[a+x-b,b+y-a,c+z+1-b],[a+x-c-1,b+y-c-1,c+z+1-c-1]]

Simplifying the matrix, we get:

[[b+y-a,a+x-b,c+z+1-a],[a+x-b,b+y-a,c+z+1-b],[a+x-c-1,b+y-c-1,c+z]]

Therefore, the value of the matrix is [[b+y-a,a+x-b,c+z+1-a],[a+x-b,b+y-a,c+z+1-b],[a+x-c-1,b+y-c-1,c+z]] when a+x=b+y=c+z+1, where a,b,c,x,y, z are non-zero distinct real numbers.

The x-intercepts of y=x2+5x−24 can be determined by solving the equation 0=x2+5x−24. Using the quadratic formula, we can find that x = 6 and x = -4 are the two x-intercepts.

The x-intercepts of y=x2−11x+10 can be determined by solving the equation 0=x2−11x+10. Using the quadratic formula, we can find that x = 5 and x = -2 are the two x-intercepts.
To determine the x-intercepts of the given functions, we need to find the values of x that make y equal to 0. We can do this by factoring the equations and setting each factor equal to 0.

2. y = x^2 + 5x - 24
0 = x^2 + 5x - 24
0 = (x + 8)(x - 3)
x + 8 = 0 or x - 3 = 0
x = -8 or x = 3

The x-intercepts are (-8, 0) and (3, 0).
3. y = x^2 - 11x + 10
0 = x^2 - 11x + 10
0 = (x - 1)(x - 10)
x - 1 = 0 or x - 10 = 0
x = 1 or x = 10

The x-intercepts are (1, 0) and (10, 0).

What is the largest possible value x could take given that it must be an integer? x < 2

Answers

The largest possible value x could take given that it must be an integer for x < 2 is 1.

Difference between an inequality and an equation?

The key distinction between an inequality and an equation is that an inequality describes a connection of inequality between two expressions, whereas an equation expresses equality between two expressions. In other words, an inequality shows that one expression is more or less than the other expression, but an equation shows that two expressions have the same value.

The highest number x might have is 1 if x must be an integer and x 2. This is due to the fact that any number higher than one would break the inequality x 2, and any number between one and two that is not an integer would also violate the stipulation that x must be an integer.

The requried combined length of both trains is 900 meters or 900 km.

What is speed?

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
Let's first convert the given speeds from km/h to m/s to make the calculations easier.

Speed of the first train = 102 km/h = (102 x 1000) m/3600 s = 28.33 m/s

Speed of the second train = 30 km/h = (30 x 1000) m/3600 s = 8.33 m/s

Now, let's consider the relative speed of the two trains since they are moving in the same direction:

Relative speed = Speed of first train - Speed of second train

= 28.33 - 8.33

= 20 m/s

Let's assume that the length of the first train is x m and the length of the second train is y m.

Distance covered by first train in 45 seconds = (x + y) m

Speed of first train = Distance covered by first train / Time taken

= (x + y) / 45 km/s

We know that the speed of the first train is 20 m/s. So, we can write:

20 = [(x + y) / 45]

Solving for (x + y),

x + y = 900 m

Therefore, the combined length of both trains is 900 meters or 900 km.

Describe the long run behavior of f(x)=5(2)x+1:
As x→−[infinity], f(x) =
As x→[infinity], f(x) =

Answers

The long run behavior of the function f(x)=5(2)x+1 is that it approaches 1 as x approaches negative infinity and it approaches infinity as x approaches positive infinity.

The long-term behavior of the function f(x)=5(2)x+1 can be discovered by examining how the function behaves as x gets closer to negative and positive infinity.

As x→−[infinity], f(x) = 5(2)^ -∞+1 = 5(0)+1 = 1

As x approaches negative infinity, the value of the function approaches 1.

As x→[infinity], f(x) = 5(2)^ ∞+1 = 5(∞)+1 = ∞

As x approaches positive infinity, the value of the function approaches infinity.

As a result, the function f(x)=5(2)x+1 behaves in the long run in such a way that it approaches 1 as x approaches negative infinity and infinity as x approaches positive infinity.

A tank contains 12 litres of water in which is dissolved 24 grams of chemical A solution containing 4 grams per litre of the chemical flows into the tank at a rate of 4 litres per minute, and the well-stirred mixture flows out at a rate of 2 litres per minute. Determine the amount of chemical in the tank after 15 minutes.

Answers

The amount of chemical in the tank after 15 minutes is 154.14 grams.

To determine the amount of chemical in the tank after 15 minutes, we need to use the formula for the concentration of a solution:

C = m/V

Where C is the concentration of the solution, m is the mass of the chemical, and V is the volume of the solution.

Initially, the tank contains 12 litres of water and 24 grams of chemical A, so the initial concentration of the solution is:

C0 = 24/12 = 2 grams per litre

The solution flows into the tank at a rate of 4 grams per litre and 4 litres per minute, so the amount of chemical flowing into the tank per minute is:

4 grams per litre × 4 litres per minute = 16 grams per minute

The well-stirred mixture flows out of the tank at a rate of 2 litres per minute, so the amount of chemical flowing out of the tank per minute is:

C × 2 litres per minute = 2C grams per minute

The net change in the amount of chemical in the tank per minute is:

16 grams per minute - 2C grams per minute = 16 - 2C grams per minute

After 15 minutes, the net change in the amount of chemical in the tank is:

(16 - 2C) grams per minute × 15 minutes = 240 - 30C grams

The final amount of chemical in the tank is:

m = 24 + 240 - 30C = 264 - 30C grams

The final volume of the solution in the tank is:

V = 12 + 4 litres per minute × 15 minutes - 2 litres per minute × 15 minutes = 42 litres

The final concentration of the solution in the tank is:

C = m/V = (264 - 30C)/42

Solving for C, we get:

42C = 264 - 30C

72C = 264

C = 264/72 = 3.67 grams per litre

The final amount of chemical in the tank is:

m = C × V = 3.67 grams per litre × 42 litres = 154.14 grams

Therefore, the amount of chemical in the tank after 15 minutes is 154.14 grams.

7. A realtor took $32,500 made on the sale of a home and placed it in a new account that earns
6% compounded annually. Find the total amount in the account after 5 years.

Please help!

Answers

Answer: The amount is $43492.35 and the interest is $10992.35.

Step-by-step explanation:

To find amount we use formula:

A = P(1+r/n)^nt

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

In this example we have

P=32,000 , R=6% , N = 1 T= 5 YEARS

After plugging the given information we have

A=32000(1+0.06/1)^1.5

A=32500*1.06^5

A=32500*1.338226

A=$43492.35

To find interest we use formula A=P+I , since A= 43492.35  P =32500  we have:

A=P+I

$43492.35 = 32500+I

I=$43492.35-32500

I=$10992.35

Richard’s Supplies sold 100 calculators in the month of August. Joseph’s Deals sold 30 calculators in the first week of October. A business consultant concluded that Richard's Supplies sells more calculators than Joseph's Deals. Explain why the statistic is misleading

Answers

The statistic that "Richard's Supplies sells more calculators than Joseph's Deals" based solely on the information given is misleading because it compares the total sales of one business for an entire month with the sales of another business for only one week.

What should be the most acceptable way to make the sales comparison in statistic?

It's possible that Joseph's Deals could sell more calculators than Richard's Supplies in a given week or even in the entire month of October, despite the fact that they only sold 30 calculators in the first week but we don't have enough information to compare the sales of these two businesses accurately.

In addition, we don't know if Richard's Supplies and Joseph's Deals are similar businesses with similar customer bases, pricing strategies, and marketing efforts. These factors could also affect their respective sales numbers.

In conclusion, to draw a meaningful comparison between the sales of these two businesses, we would need to gather more data about their sales over a longer period of time and under similar conditions.

The method for calculating the area of a figure depends on the type of figure.

How to calculate the area

Here are some common formulas for finding the area of different shapes:

Square: To find the area of a square, you multiply the length of one side by itself: Area = side x side or A = s²

Rectangle: To find the area of a rectangle, you multiply the length by the width: Area = length x width or A = lw

Triangle: To find the area of a triangle, you multiply the base by the height and divide by 2: Area = 1/2 x base x height or A = 1/2 bh

Circle: To find the area of a circle, you multiply pi (3.14) by the radius squared: Area = pi x radius^2 or A = πr^2

Trapezoid: To find the area of a trapezoid, you multiply the average of the bases by the height: Area = 1/2 x (base1 + base2) x height or A = 1/2 (b1 + b2)h

These are just some of the formulas for calculating the area of different shapes. Depending on the figure you're working with, you may need to use a different formula or combination of formulas to find the area.
