Paul drew two circles. One circle has a radius of 8 centimeters and the other has a radius of 12 centimeters, as shown.
12 cm
8 cm
Paul says that the area of the shaded section between the two circles is 16 square centimeters because A = *(12 - 8) = 16

What is the equation of the line that passes through the point (1,3) and has a slope
of -- 32

Answers

Answer:

The equation of the line that passes through the point (1,3) and has a slope  of -32.

[tex]y=-32x+35[/tex]

Please check the attached graph too.

Step-by-step explanation:

Given

Point (1, 3) The slope m = -32

The point-slope form:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

m is the slope of the line (x₁, y₁) is the point

In our case:

m = -32

(x₁, y₁) = (1, 3)

substituting m = -32 and (x₁, y₁) = (1, 3) in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-3=-32\left(x-1\right)[/tex]

Add 3 to both sides

[tex]y-3+3=-32\left(x-1\right)+3[/tex]

Simplify

[tex]y=-32x+35[/tex]

Therefore, the equation of the line that passes through the point (1,3) and has a slope  of -32.

[tex]y=-32x+35[/tex]

Answer: m=13

Step-by-step explanation:

Basically you solve this by finding out what plus 4 equals 17. You can do this by subtracting 4 from 17.

17-4=13

This is how you find the value of m.

Answer:

13!

Step-by-step explanation:

first subtract 4 on both sides!

m+4=17

m+4-4=17-4

9 times what number equals 800?

Answers

Answer:

9 times 800/9 equals 800. (Answer is 800/9)

Step-by-step explanation:

Key skills needed: Equation, Division, Fractions

1) Let's say the number is the variable "x".

2) So this means 9 times x = 800

9x = 800

3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9

Hope you understood and have a nice day!! :D

88.8888888889

The equation to any of these sorts of questions is the larger number (800) divided by the smaller number (9).

You can check your answer by multiplying the quotient by the smaller number (9). If you get the larger number (800), you were correct, anything else, the equation was done wrong.

Which expression is equivalent to 4t + 3t

Answers

Answer:

 C

Step-by-step explanation:

i think

Answer:

C. 7t

Step-by-step explanation:

What we know:

We are looking for an expression equal to 4t + 3t.

There are 4 choices:

1. 7t²

2. 7 + 2t

3. 7t

4. 12t

The answer does end in t, but is only one term, so B is eliminated.

An exponent is not involved either, so A is also eliminated.

It shows an addition sign, not multiplication, so D is also out.

This leaves C, which is 7t.

Doing this mathematically, add like terms.

4t + 3t

7t

What is the greatest common factor of 15 and 21?​

Answers

Greatest common factor (GCF) of 15 and 21 is 3. We will now calculate the prime factors of 15 and 21, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 21.

The Greatest Common Factor of 15 and 21 is 3.

What is Greatest Common Factor?

The greatest common factor is the largest number that is a factor of two or more numbers (GCF). The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both. The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the Highest Common Factor (HCF)

Given:

We have to find the greatest common factor of 15 and 21 .

So factorizing each number

15 = 3 x 5

21 = 3 x 7

So, the Greatest Common Factor is 3.

A school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping. How much did they make selling balloons?

Answers

Answer:

OMG, Nickkkkk. It's Nyla from your 3rd block math classs. Lol, I literally looked up this question with no luck of an answer.

Step-by-step explanation:

The school club made $298.08 by selling the balloons.

What is Profit?

Profit is calculated as total revenue less total expenses.

Given that, a school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping.

Cost of balloons when they brought them = 1.29*150 = $193.5

Total cost = $193.5 + (shipping price) = $193.5 + $8.92

Total cost = $202.42

Cost at which they sold the balloons = 143*$3.50 = $500.5

Therefore, their total profit = $500.5 - $202.42 = $298.08

Hence, The school club made $298.08 by selling the balloons

Answer:

scale factor: 3

Step-by-step explanation:

For this I will take both A and A' points. So A is (2,2) and A' is (6,6) and since the shape increased in size that means our scale factor must be greater than 1. So all that we have to do is know is how did we get from this x value to that x value or in other words 2 times what equals 6 and it's 3. Then we would do the same for the y value but since it would be the same 2 times what equals 6 and it's still 3 so 3 is the scale factor.

The graph of the equations (y = 10x + 100), (y = 10x), and (y = 12.5x) can be drawn by using the rules of transformation.

Given :

y = 100 + 10x

y = 10x

y = 12.5x

The following steps can be used to sketch the graph of the given line (y = 100 + 10x):

Step 1 - First sketch the graph of (y = x).

Step 2 - Then Multiply the x-axis by a factor of 10. The resulting graph is the graph of (y = 10x)

Step 3 - Then find the y-intercept from the given equation. Then draw the line that passes through (0,100). The resulting line is the graph of (y = 100 + 10x).

The following steps can be used to sketch the graph of the given line (y = 10x):

Step 1 - First sketch the graph of (y = x).

Step 2 - Then Multiply the x-axis by a factor of 10. The resulting graph is the graph of (y = 10x)

The following steps can be used to sketch the graph of the given line (y = 12.5x):

Step 1 - First sketch the graph of (y = x).

Step 2 - Then Multiply the x-axis by a factor of 12.5. The resulting graph is the graph of (y = 12.5x)

The graph of all the equations together is attached below.

Red line shows the graph of (y = 10x + 100).

Blue line shows the graph of (y = 10x)
