Natalie is solving a problem. What are some steps she might take after reaching her solution?

1 answer:

8 0

The answer is options C and D

When you are checking over your work and solution, you C) want to make sure you include the correct units so that the answer makes sense in the context of the question and D) see if the answer is reasonable. For example, if I say 2(3)+1=6839, does this make sense? No, especially because the numbers in the question are small integers and could not result in such a large value.

Drew burned 1,800 calories Friday playing 1 hour of basketball and canoeing for 2 hours. On Saturday, he spent 2 hours playing b

V125BC [204]

Answer:

He burnt 1000 calories per hour when playing basketball.

Step-by-step explanation:

Let B be calories burned playing basketball, and C calories burned canoing.

1800 = B + 2C

3200 = 2B + 3C

From 1st equatipn, we get that B = 1800 - 2C

Replacing into the 2nd equation, we have:

3200 = 2(1800-2C) + 3C

3200 = 3600 - 4C + 3C

3200 = 3600 - 1C

C = 3600 - 3200

C = 400

Knowing C, we find B.

B = 1800 - 2C = 1800 - 2*400 = 1800 - 800 = 1000 calories.

What is the exact volume of the cone?<br> base 7in <br> height 4in <br><br> PLEASE HELP ASAP

torisob [31]

The volume formula of a cone is $\frac{1}{3} \pi r^{2} h$ the r is the radius and h is the height. However, if you multiply by pi, you will get an approximated volume of the cone. So we will multiply like this for now. $\frac{1}{3} r^{2} h$ Don't worry, we'll use pi in the end.

I'm going to assume that 7 inches is your radius. We need to plug in 7 for r and 4 in for h into the equation. Once we do that, it will look like this. $\frac{1}{3} 7^{2} 4$

$\frac{1}{3}$ means we will need to divide one by 3. That gives us 0.33333... now we have to multiply by $7^{2}$ we get 16.33333... now the last thing we need to do is multiply by 4, which is h. We get 65.33333. Add pi and you have your answer. $65.333333333 \pi$
