What are the dimensions of the base of the pyramid?

choices
8 ft by 6 ft
8 ft by 3 ft
6 ft by 3 ft
8 ft by 9 ft

Answers

The answer is 8ft by 3ft
I believe the answer is B) 8ft by 3ft

I say this because we are looking at the base of the shape, and the triangle is not the base. So we would skip over the 6ft and that leaves us with this answer.

Hope this helps! :)

Answer:
Step-by-step explanation:
Let's check all the monomials

Here 6 is not square digit, hence this monomial is not a perfect square.

Here 9 is a square digit and the power of x i.e. 8 is multiple of 2 .
Hence, this monomial is a perfect square.

Here 16 is a square digit but the power of x i.e.9 is not multiple of 2 .
Hence, this monomial is not a perfect square.

Here 25 is a square digit and the power of x i.e. 12 is multiple of 2 .
Hence, this monomial is a perfect square.

Here 36 is a square digit and the power of x i.e.16 is multiple of 2 .
Hence, this monomial is a perfect square.

Board Game Sales

A small company is selling a new board game, and they need to know how many to produce in the future.

After 12 months, they sold 4 thousand games; after 18 months, they sold 7 thousand games; and after 36 months, they sold 15 thousand games.

This information could be reasonably estimated using a single linear model?
Group of answer choices

True

False

If so, use the model to estimate the number of games sold after 48 months. If not, explain your reasoning.

Answers

Answer:

true

Step-by-step explanation:

False

The amount of games sold is not linear. If it were linear, the amount of games sold at 36 months would be 12 thousand games, assuming we are going off of the information given at 12 months

Answers

Answer: 39°, 72°, 45°, 150°

Step-by-step explanation:

A circle has 360 degrees. [tex]\frac{1}{360}[/tex] would be equal to 1°

1) [tex]\frac{39}{360}[/tex] would be equal to 39° based on the rule above ^^

2) This fraction has a denominator of 5. Turn the denominator into 360. We can do this by multiplying the bottom by 72, since 360 ÷ 5 = 72 (make sure to multiply the numerator by 72 as well!)

[tex]\frac{1*72}{5*72}[/tex] = [tex]\frac{72}{360}[/tex]

This is equal to 72°

3) Use the same method as before

[tex]\frac{1*45}{8*45}[/tex] = [tex]\frac{45}{360}[/tex]

This is equal to 45°

4) Use the same method as before

[tex]\frac{5*30}{12*30}[/tex] = [tex]\frac{150}{360}[/tex]

This is equal to 150°
