What is the slope of the line that passes through the points (-9, -7) and (-11, -6)? Write your answer in simplest form

Answer:

\(A = \dfrac{C^2}{4\pi}\)

Step-by-step explanation:

Given that

Area of a circle \(A=\pi r^2\)

Circumference of the circle \(C = 2 \pi r\)

Let us re-write the equation of area of circle:

\(A=\pi r^2\)

\(A = \pi \times r \times r\)

Multiplying and dividing with 2:

\(A = \dfrac{2\pi r}{2} \times r\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C}{2} \times r\\\text{Multiplying and dividing by } 2\pi:\\\Rightarrow A = \dfrac{C}{2} \times \dfrac{2\pi r}{2\pi}\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C \times C}{4 \pi}\\\Rightarrow A = \dfrac{C^2}{4 \pi}\)

Hence, A in terms of C can be represented as:

\(A = \dfrac{C^2}{4\pi}\)

Answer: The Pyramid has 2 pairs of congruent faces

Step-by-step explanation:

The explanation of congruent is the face has the same shape and same size. On rectangle pyramid, the height triangle are 2 same faces and 2 same faces, so it has 2 pairs of congruent faces

I think row A would be 5 and B would be 9 im sorry if im wrong

Answer:

42.25

Step-by-step explanation:

6.5^2

6.5*6.5=42.25

multiply 6.5*6.5 (it's basically just another way of saying 6.5^2) then there is ur answer

Have a great day

Answer: five times two times four plus three plus four

Step-by-step explanation:

5[2(4) + 3 +4]

whenever you have a number next to a bracket, like [ or ( ,it always means multiply. So thats how i know 5[2(4) means "five times two times four" as a verbal expression. The last part is "3+4" which translates to "three plus four"

I hope this is correct!!!

Answer:

C: 18

Step-by-step explanation:

All you have to do is write down the ratio. Then you find out that 21 is half of 42 so that means that the amount of zookeepers that you will have to add should be half the amount as well so instead of 12 it would be 6. Then you just add the two numbers together to get your final answer of 18.

Answer: 1: Divisible.  2: Not divisible.  3: Divisible.  4: Not divisible.  5: divisible.   6:Divisible.    Part 2: 7: 2,5,10.   8: 5   9: 2  10: 2  11: 2,5,10.  12: none

Answer:

y = 6x + 1 (0,2) (5,0)

Step-by-step explanation:

Really just need to pay attention where the x coordinate is at. If at 0, and the y coordinate is elsewhere, you will be able to tell where the y intercept is. Usually, you quickly draw a graph if the numbers are more complex.

Answer:

Sergio's strategy was to multiply the sum of the length and width of the rectangle by 2. This was one correct way to find the perimeter of the rectangle.

Jamie's strategy was to add the given measurements of the length and width of the rectangle together. This was another correct way to find the perimeter of the rectangle.

Karina's strategy was to multiply the given length of the rectangle by 2 and add this product to the width of the rectangle. This was NOT a correct way to find the perimeter of the rectangle, as it did not follow the formulas to finding the perimeter of a rectangle: l + w + l + w, or 2(l + w) and furthermore formulas that explain the same thing. Karina only multiplied the length by 2 and did not account for the width of the retangle which she should have done as well.  

Ethan's strategy was to multiply the width by 2, multiply the length by 2, and add these two products together to find the perimenter. This final strategy was correct, and can be used to find the perimeter of the rectangle.

Hope this helps you! I love doing math, so enjoy!

Step-by-step explanation:

300-30=270

270÷7.50=36

Answer:

36

Step-by-step explanation:

300 - 30 = 270

270 ÷ 7.50 = 36

Answer: L 38

Answer: 48 small shirts

108 medium shirts

84 Large shirts

Step-by-step explanation:

20% of 240 = 48

45% pf 240 = 108

45 + 20 = 65, 100 - 65 = 35

35% of 240 = 84

And 48 + 108 + 84 = 240

Answer:

9 plums and 15 oranges

Step-by-step explanation:

3+3+3 = 9 plums

5+5+5= 15 oranges

1+1+1= 3 apples

Answer: C, E, D, A, B

Answer:

1. C

2.E

3.D

4.A

5.B

those are the answers

Answer: The answer is 120

Step-by-step explanation:

We know that 36 is 30% of total items

So our equation would be 36/? = 30/100

From there we cross multiply so 36x100 = 3600

From there, we divide 3600 by 100

Therefore, your answer is 120

Answer:

No.

Step-by-step explanation:

In a function, two points CANNOT be directly above each other. In this case, (1,3) and (1,-2) are above each other.

Answer: 87 people

Step-by-step explanation:

9,602 = 96x + 25(50)

9,602 = 96x + 1250

9,602 - 1250 = 8352

8352 ÷ 96 = 87

Answer:

25% will be your answer.

Answer:

'-5'

Step-by-step explanation:

The table is a linear function. This means that all the points have a consistent slope. If two points had a different slope, it would be a nonlinear function.

Slope is rise over run. We are given the points (-3,0) and (-2,-5).

\(m=\frac{-5-0}{-2+3}=\frac{-5}{1}=\huge\boxed{-5}\)

Answer:

-5

Step-by-step explanation:

Answer:

Step-by-step explanation:

As the angles are supplementary, they sum up to 180

Hence, 3x+40+80=180

3x+120=180

3x=60

x=20
