Step-by-step explanation:

Answer:

Infinutely many solutions

Step-by-step explanation:

y = 10x + 2 --------- (1)

y = 8x +2x +2

=> y = 10x + 2---------- (2)

(1) -> 10x -y + 2 = 0

(2) -> 10x -y + 2 = 0

a1=10 ; b1=-1 ; c1 = 2

a2=10 ; b2=-1 ; c2= 2

a1/a2 = 10/10 = 1

b1/b2 = -1/-1 = 1

c1/c2 = 2/2 = 1

therefore, a1/a2 = b1/b2 = c1/c2

Therefore the line coincides and there are infinitely many solutions.

Answer:

Speed of car in miles per minute = 0.8 miles per minute

Distance cover by car in 20 minutes = 16 miles

Step-by-step explanation:

Given:

Speed of car = 48 miles per hour

Time taken by car = 20 minutes

Find:

Speed of car in miles per minute

Distance cover by car in 20 minutes

Computation:

Speed of car = 48 miles per hour

1 hour = 60 minutes

So,

Speed of car = 48/60 miles per minute

Speed of car in miles per minute = 0.8 miles per minute

Distance cover by car in 20 minutes = 20 x Speed of car in miles per minute

Distance cover by car in 20 minutes = 20 x 0.8

Distance cover by car in 20 minutes = 16 miles

A triangle that is equilateral has three equal sides and three equal angles.

The angles are all 60 degrees each. Two 90-degree angles are formed when the height of an equilateral triangle is drawn to the base of the triangle, and the top angle is divided into two 30-degree angles. A triangle with sides of 30-60-90 always has sides that are 1:3:2.

The 30-60-90 triangle formula for sides y is also known as y3: 2y. The angles of the triangle are always 30, 60, and 90 degrees. Given that one of the angles is 90 degrees, this triangle is always a right triangle. These angles come together to form a right-angled triangle. Furthermore, the right angle is equivalent to the sum of two sharp angles, which will have the ratios of 1: 2 or 2: 1.

Answer:

a = 4√2, h = 2√3

The equation is y = 2x and the constant of variation k = 2

Therefore, the correct answer is option d.

Here, we can clearly see that y varies directly with x, because as x increases, y increases with the same proportion and vice versa. The constant of variation, k, is the coefficient of proportionality between x and y. To find the constant of variation, we can divide the value of y by the value of x for any one of the given points.

For example, for the point (-2, -4) we have:

k = -4 / -2 = 2

So the equation relating x and y is: y = kx = 2x

Hence, the equation is y = 2x and the constant of variation k = 2

Therefore, the correct answer is option d.

On solving the provided question, we can say that - here in the percentage obtained = 40 => so, 40/100X100 = 40%

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

here,

total is = 100

obtained = 40

The function of the scenario is f(x) = 18.5(1.06)^x

From the question, we have the following parameters that can be used in our computation:

Initial value = $18.50

Rate = 6%

The function of the scenario is then represented as

f(x) = Initial value * (1  + rate)^x

Substitute the known values in the above equation, so, we have the following representation

f(x) = 18.5(1 + 6%)^x

Evaluate

f(x) = 18.5(1.06)^x

This means that

x = 10

So, we have

f(10) = 18.5(1.06)^10

Evaluate

f(10) = 33.13

This means that

x = -15

So, we have

f(-15) = 18.5(1.06)^(-15)

Evaluate

f(-15) = 7.72

It would take about 17.4 years, to the nearest year, for the value of the account to reach $142,200 if the interest rate is 4.6% and no deposits or withdrawals are made.

Therefore the answer is 17.4 years.

To find out how long it would take for the value of the account to reach $142,200, we need to use the formula for compound interest:

A = P(1 + r)^(t)

Where:

A = the future value of the account

P = the present value of the account ($65,000)

r = the annual interest rate (4.6%)

t = the number of years

We know the future value of the account (A) and the present value of the account (P), so we can substitute these values into the formula and solve for t:

142,200 = 65,000(1 + 0.046)^t

To solve for t, we can take the natural logarithm of both sides:

ln(142,200) = ln(65,000(1 + 0.046)^t)

ln(142,200) = ln(65,000) + t(ln(1 + 0.046))

Then we can divide both sides by ln(1+0.046) and take the power of e:

t = (ln(142,200) - ln(65,000)) / ln(1+0.046)

To the nearest year, this gives us t = 17.4 years.

If yes, then both statements are true

As a further explanation, we consider a roll of die.

The sample space is:

[tex]S = \{1,2,3,4,5,6\}[/tex]

Because 1 to 6 appear just once on the die, then each have a probability of 1/6

[tex]Pr = \frac{1}{6}[/tex] --- This is referred to as the theoretical probability

But if after rolling the die 6 times, the outcome is:

[tex]Outcome = \{1,1,4,5,1,2\}[/tex]

The experimental probability of (say 1) is, the number of times 1 appeared divided by the number of times the experiment is carried out.

Answer:

b:  5x-4y+31=0

Step-by-step explanation:

Let's look for an equation of the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).

We are given the slope, m, as (5/4), so we can write:  y = (5/4)x+b.

To find b, just enter the given point, (-3,4), into the above equation and solve for b:

 y=(5/4)x + b

 4=(5/4)(-3) + b   for (-3,4)

 4 = -(15/4)+b

 4 + (15/4) = b

 4 + (3 3/4) = b

b = 7 3/4

The equation becomes y = (5/4)x + 7 3/4

Also written as:  y = (5/4)x + (31/4)

To match this with one of the options, let's multiply by 4 to remove the two fractions:

   y = (5/4)x + (31/4)

   4y = (5)x + (31)

Rearrange so that the expression is = 0:

4y-5x-31 = 0

Now multiply by -1:   -4y+5x+31=0

Rearrange and this will match option b:  5x-4y+31=0

Solving for x and y intercepts when given an equation:

X-intercept:

[tex]2x-5(0)=20[/tex]

[tex]2x=20[/tex]

[tex]x=10[/tex]

x-intercept occurs at (10,0)

Dominique is decorating a round cake with fruits and has frosted just the top of the cake. To determine the area of the cake that is covered with icing, we can use the formula (π * radius2). Since the cake is round, we can determine the radius of the cake by dividing the diameter of the cake (16 inches) by 2, resulting in the radius being 8 inches. We can then calculate the area of the cake covered with icing by multiplying π by the radius squared. Using the number 3.14 for π, the calculation is 3.14 * (8 inches)2, which equals 201.06 square inches. Therefore, 201.06 square inches of the cake are covered with icing.
