If you could provide me more details, including the dimensions of the two triangle ' angles and sides, I might be able to evaluate whether or not they are comparable.

What precisely is a triangle?

A triangle is a polygon because it includes four or so additional parts. It features a simple rectangular shape. A rectangle having edges A, B, and C is referred to as a triangle. When the sides are actually not collinear, Euclidean geometry yields a single plane and cube. If a triangle contains three parts and three angles, it is a polygon. The intersections of a triangle's three sides are referred to as its corners. The sum of a triangle's sides is 180 degrees.

Two polygons must have congruent corresponding angles and proportionate corresponding sides in order to be considered comparable.

Find the value of the variable y when

the sum of fractions [tex]\frac{y+1}{y-5}[/tex] and [tex]\frac{10}{y+5}[/tex] is equal to their product.

Answers

The value of y that satisfies the equation is y = -11.

Describe Equation?

An equation is a mathematical statement that expresses the equality of two expressions. It typically consists of two sides, separated by an equals sign (=), with each side containing one or more terms that may include variables, constants, and mathematical operators.

We can start by setting up the equation:

(y+1)/(y-5) + 10/(y+5) = (y+1)/(y-5) × 10/(y+5)

To solve for y, we need to simplify and manipulate the equation:

Multiply both sides by (y-5) × (y+5) to eliminate the denominators:

(y+1)(y+5) + 10(y-5) = 10 × (y+1)

Expand and simplify:

y² + 6y - 15 + 10y - 50 = 10y + 10

Combine like terms:

y² + 16y - 55 = 0

Factor the quadratic:

(y + 11)(y - 5) = 0

Solve for y:

y = -11 or y = 5

However, we need to check if either solution makes the denominators of the original equation equal to zero, since division by zero is undefined:

For y = -11, the denominators are -16 and -6, respectively, which are both nonzero. Therefore, y = -11 is a valid solution.

For y = 5, the denominator of the first fraction is 0, which is not allowed. Therefore, y = 5 is an extraneous solution and should be discarded.

Therefore, the value of y that satisfies the equation is y = -11.

Students are making lemonade from a powdered lemon drink mix.
Wyatt mixes 2 cups of water and 1 cup of powdered lemon mix. Emma
mixes 12 cups of water and 7 cups of powdered lemon mix. Use Wyatt
and Emma's percent of water to determine whose mix will be more
watery.

Answers

Wyatt's mix will be more watery compared to Emma's mix.

What does it mean for a mixture to be "more watery"?

The percentage of water in a mix is an essential factor that determines its taste, texture, and consistency. A higher percentage of water in a lemonade mix will make it more watery and less concentrated. In contrast, a lower percentage of water will make the mix less watery and more concentrated. The right balance of water and lemon mix is crucial to make a perfect lemonade.

Calculation for percent of water in the lemon drink mix:

To find the percent of water in the lemonade mixes, we need to divide the amount of water by the total volume of the mix and then multiply by 100.

For Wyatt's mix:

Percent of water = (2 cups water / (2 cups water + 1 cup lemon mix)) x 100

Percent of water = 66.67%

For Emma's mix:

Percent of water = (12 cups water / (12 cups water + 7 cups lemon mix)) x 100

Percent of water = 63.16%

From the calculations, we can see that Wyatt's mix has a higher percentage of water than Emma's mix. Therefore, Emma's mix will be less watery compared to Wyatt's mix.

3. John wants an average bowling score of 215. If he scored 159, 182, 225, 240, 198,
200 and 230 on his first seven games, what must he score on his 8th game to achieve
this average?

Answers

John must score 286 on his 8th game to achieve an average score of 215.

What is an Average?

Average, also known as the mean, is a mathematical concept that represents the central value of a set of numbers. It is found by dividing the sum of the numbers by the total count of the numbers.

To find out what John must score on his 8th game to achieve an average score of 215, we need to use the formula for calculating the average or mean:

Average = (Sum of Scores) / (Number of Scores)

We can use this formula to solve for the unknown score:

215 = (159 + 182 + 225 + 240 + 198 + 200 + 230 + x) / 8

Multiplying both sides by 8, we get:

1720 = 159 + 182 + 225 + 240 + 198 + 200 + 230 + x

Simplifying, we get:

1720 = 1434 + x

Subtracting 1434 from both sides, we get:

x = 286

Therefore, John must score 286 on his 8th game to achieve an average score of 215.

The mass of a substance, which follows a continuous exponential growth model, is being studied in a lab. A sample increases continuously at a relative rate of 7% per day. Find the mass of the sample after six days if there were 552 grams of the substance present at the beginning of the study.
Do not round any intermediate computations, and round your answer to the nearest tenth.

Also, may you please explain how you got the answer, it would be very helpful because I don't understand how to solve this. Thank you!

Answers

Answer:

864.3

Step-by-step explanation:

Since the substance is increasing continuously at a relative rate of 7% per day, we can use the continuous exponential growth formula:

P(t) = P(0) * e^(rt)

where:

P(t) is the mass of the substance after "t" days

P(0) is the initial mass of the substance (552 grams in this case)

e is the mathematical constant e (approximately equal to 2.71828)

r is the relative growth rate (0.07 per day in this case)

Substituting the given values, we get:

P(t) = 552 * e^(0.07t)

To find the mass after 6 days, we can substitute t = 6:

P(6) = 552 * e^(0.07*6)

Using a calculator, we get:

P(6) ≈ 864.3 grams

Therefore, the mass of the substance after 6 days is approximately 864.3 grams rounded to the nearest tenth.

Probability is the measure of how likely a certain event is to occur. It is a mathematical concept that is used to quantify the likelihood of a certain outcome from a given set of circumstances. Probability is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain. Probability is used in many fields, including mathematics, finance, and decision making.

This is because approximately 68% of the data is within one standard deviation of the mean, and the data is normally distributed. The area between the mean and the upper limit of 1819 is 0.68, which means that the graph probability of a randomly selected tester from this group having a score between 1497 and 1819 is 0.68.

The total number of dimes in the container is 6 while the total number of quarters is 11.

How to solve the problem

To solve this problem, we will be using the simultaneous equation. The dimes and quarters will be assigned some figures:

First:

d + q = 17

10d + 25q = 335

This second equation is so because the value of the coins was converted to cents.

Where $1 = 100 cents

Next, we will resolve the figures to get the values for d and q as follows:

Multiply both sides of the first equation by -10

-10d - 10q = -170

Now, we shall minus the first equation from the second one to give:

15q = 165

q = 165/15

= 11

Substitute the value of q in the first equation:

d + 11 = 17

d = 17 - 11

d = 6

Substituting the values in the original equation will give the final sum of 335 for the coins.

To add or subtract fractions with the same denominator, you simply add or subtract the numerators and keep the same denominator. Then, simplify the fraction if possible.

In this case, the fractions have the same denominator of 8, so we can simply add the numerators:

(1)/(8) + (5)/(8) = (1 + 5)/(8) = (6)/(8)

Now, we need to simplify the fraction by finding the greatest common factor (GCF) of the numerator and denominator. The GCF of 6 and 8 is 2, so we can divide both the numerator and denominator by 2 to get:

Kuro has a stack of 15 coins on a table with a volume of 8 cubic centimeters. He has stacked them perfectly straight creating a cylindrical shape. He accidentally bumps the table, causing the coins to shift to a leaning position; but are still stacked. What would be the best estimate of the volume of the stack once it has been bumped/shifted?

Answers

The best estimate of the volume of the stack once it has been bumped/shifted is 4πt³ cubic centimeters.

Describe Volume of cylinder?

A cylinder is a three-dimensional geometric shape that consists of two parallel circular bases connected by a curved surface. The volume of a cylinder is the amount of space occupied by the shape and is given by the formula:

Volume = πr²h

where π (pi) is a mathematical constant approximately equal to 3.14, r is the radius of the circular base, and h is the height of the cylinder.

Assuming that the coins have the same dimensions and are perfectly circular, the original stack of 15 coins formed a cylinder with a height of 15 times the thickness of a single coin, and a radius equal to the radius of a single coin.

The volume of this cylinder can be calculated using the formula V = πr²h, where r is the radius and h is the height.

Since the volume of the original stack is 8 cubic centimeters, we can set up the equation:

8 = πr²(15t)

where t is the thickness of a single coin.

Solving for r, we get:

r = √(8/15πt)

When the stack is bumped and shifts to a leaning position, the new shape will still be a cylinder, but the height will be shorter than before. Let's say that the new height is h2. We can calculate the new volume using the same formula:

V2 = πr²h2

To estimate the new height, we can use the fact that the coins are now leaning against each other, so the new height will be less than 15t. Let's say that the new height is approximately 12t.

Substituting in the values, we get:

V2 = π(√(8/15πt))²(12t)

Simplifying, we get:

V2 = 4πt³

Therefore, the best estimate of the volume of the stack once it has been bumped/shifted is 4π³ cubic centimeters.

the circumference of a circle is 23r cm. what is exact the area of the circle?

Answers

As a result, the circle's precise size is (529/4)π³  square centimetres.

Explain what a circle is?

A circle is a closed, two-dimensional shape where every point in the surface is equally spaced from a central point. The line of mirror symmetry is formed by all lines that traverse the circle. Additionally, every point has circular symmetry around the centre.

The circumference of a circle is given by the formula:

C = 2πr

where r is the radius of the circle. We can rearrange this formula to solve for the radius:

r = C / 2π

When we substitute the circumference's specified number, we obtain:

r = (23r) / (2π)

Simplifying:

r = (23/2)π

Now that we know the radius, we can use the formula for the area of a circle:

A = πr²

Substituting the value we found for the radius, we get:

A = π[(23/2)π]²

Simplifying:

A = π(529/4)π²

A = (529/4)π³

For the first equation: 8(2) + 7(1) = 16 + 7 = 23

For the second equation: 2 + 1 = 3

Hence, we can see that both equations are true when x = 2 and y = 1.

Therefore, (2,1) is a solution to the system of equations.

Practice math quadratic equation
4a^2+6=0

Answers

The given quadratic equation does not have a real solution.

What are Quadratic Equations?

Quadratic equations are polynomial equations of second degree.

The general form of a quadratic equation is ax² + b x + c = 0.

The given quadratic equation is,

4a² + 6 = 0

We have to find the solution of the quadratic equation.

Subtracting both sides by 6,

4a² + 6 - 6 = 0 - 6

4a² = -6

a² = -6/4

a² = -3/2

Taking square root on both sides,

a = √(-3/2), which implies that the given quadratic equation does not have a real solution.

Hence there are no real solution for the given equation.

13. The scale on a map is 1 : 20 000.
The area of a lake on the map is 1.6 square centimeters.
Calculate the actual area of the lake. Give your answer in square meters.

Answers

The actual area of the lake 64000 square meters.

What is ratio?

When two numbers are compared, the ratio between them shows how often the first number contains the second. As an illustration, the ratio of oranges to lemons in a dish of fruit is 8:6 if there are 8 oranges and 6 lemons present.

In this given question, we are first of all going to use the given ratio of the on map measurements to the actual measurements, that is 1:20000 to calculate the actual measurements as follows:

[tex]1.6cm^2=1\times 1.6cm^2[/tex]------->1

Using the ratio 1:20000 in 1.1, we get,

[tex]1.6\times1 cm^2= 1.6\times (20000)^2 cm^2 = 1.6\times 400000000 cm^2 = 640000000cm^2[/tex]-----> 2

As the actual measurement of the area of the lake.

So, 1m = 100 cm

=> [tex](1m)^2=(100cm)^2[/tex]

=> [tex]1m^2 = 10000cm^2[/tex]-------> 3

So, using equation 3 in the value obtained 2, we get,

=> [tex]640000000cm^2 = \frac{640000000}{10000} = 64000m^2[/tex]

Hence the actual area of the lake is 64000 square meters.

Determine the LCM of the given polynomials: Leave your answer in factored form. \[ x^{2}+8 x+16 \text { and } x^{2}+11 x+28 \]

Answers

The LCM of the polynomials x² + 8x + 16 and x² + 11 x + 28 is (x + 4)(x + 4)(x + 7).

To determine the LCM of the given polynomials, we need to find the smallest polynomial that is a multiple of both  x² + 8x + 16 and x² + 11 x + 28.

First, let's factor the given polynomials:
x² + 8x + 16 = (x + 4)(x + 4)

x² + 11 x + 28 = (x + 4)(x + 7)

Now, we can see that the LCM of these two polynomials is the product of the highest power of each factor:

LCM = (x + 4)(x + 4)(x + 7)

So, the LCM of the given polynomials in factored form is (x + 4)(x + 4)(x + 7).

The estimated population, in thousands of people , of city A can be modeled by the function f(t)=15(1. 03) , where is the number of decades (10-year period) since 1980 the estimated population , in thousands of people , of city B can be modeled by the function g(t)=0. 4t+16, where t is the number of decades since 1980

Answers

Part A) Estimated Populations of Cities A and B are given.

Part B)  City A's estimated population is increasing at a faster rate than City B's estimated population for each decade.

Part C) the estimated population of City A first exceeds the estimated population of City B at the start of the 4th decade (t = 3)

Part D) The models may not realistically predict population growth over very long time scales, as they do not take into account other factors  

Part A:

Estimated Populations of Cities A and B

Decades Since 1980  City A (in thousands)          City B (in thousands)

0                                       15                                           16

1                                  19.5                                   16.4

2                                  25.2                                   17.8

3                                  32.7                                   19.2

4                                  42.4                                    20.6

Part B:

Population Increases from the previous Decade for Cities A and B

Decades Since 1980 City A (in hundreds)           City B (in hundreds)

0                                         -                                                   -

3                                       750                                               140

4                                       970                                               140

Interpretation:

From the table, we can see that City A's estimated population is increasing at a faster rate than City B's estimated population for each decade. This indicates that City A is growing more rapidly than City B, and may continue to do so in the future.

Part C:

To find the start of the decade when the estimated population of City A first exceeds the estimated population of City B, we need to solve the equation:

15[tex](1.03)^t[/tex] > 0.4t + 16

where t is the number of decades since 1980.

One way to solve this is to use a graphing calculator to graph both functions and find their intersection point. Alternatively, we can use trial and error to test different values of t until we find the smallest one that satisfies the inequality.

Using a graphing calculator, we find that the estimated population of City A first exceeds the estimated population of City B at the start of the 4th decade (t = 3), when the estimated population of City A is approximately 32.7 thousand people, and the estimated population of City B is approximately 19.2 thousand people.

Part D:

The models may not realistically predict population growth over very long time scales, as they do not take into account factors such as changes in birth and death rates, migration patterns, and economic or environmental changes that may affect population growth. Additionally, the models assume that population growth will continue to follow a linear or exponential pattern, which may not be accurate in the long term. Therefore, while the models can provide useful estimates for short- to medium-term population trends, they should be used with caution when making long-term projections.

If the expression x -2 y-4 3 sqrt 64xy³ is written in the form axby, then what is the
product of a, b and c?

Answers

The expression x -2 y-4 3 sqrt 64xy³ can be written in the form axby as follows:

ax -2by-4c 3 sqrt 64xy³

What is coefficient?

Coefficient in mathematics is a numerical value that is used to represent the magnitude of a given quantity in an equation. It is normally the numerical factor associated with the variables in an equation that represent a certain amount of change in the equation. For example, the coefficient of x in the equation y = 5x + 7 is 5, which indicates that x is multiplied by 5 in the equation.

In this expression, a, b, and c refer to the coefficients of the x, y, and the cube of y respectively. Thus, a is equal to 1, b is equal to -2, and c is equal to -4. Therefore, the product of a, b and c is equal to 8.

To break down the expression further, the coefficient of x is a, which is equal to 1. The coefficient of y is -2b, which is equal to -2. The coefficient of the cube of y is -4c, which is equal to -4. Finally, the coefficient of the square root of 64xy³ is 3, which is equal to 3.

Thus, when written in the form axby, the expression x -2 y-4 3 sqrt 64xy³ is equal to 1 -2 -4 3 sqrt 64xy³. The product of a, b, and c in this expression is equal to 8.
