Answer:
A. 72 in^2.
Step-by-step explanation:
What you do is you have to use the formula for a surface area of a rectangular prism which is:
A=2(wl+hl+hw).
<u><em>Your height is 3 inches. </em></u>
<u><em>Your width is 2 inches.</em></u>
<u><em>Your length is 6 inches. </em></u>
You will plug that into the formula.
A=2(2*6+3*6+3*2).
A=2(12+18+6)
A=2(36)
A=72 in^2 is your answer.
Answer: 42
Step-by-step explanation:
Let A represents the number of freshmen participated in sports and B represents the number of freshmen participated in clubs.
Then , we have given that
![n(A)=55\\\\n(B)=68\\\\n(A\cup B)=110](https://tex.z-dn.net/?f=n%28A%29%3D55%5C%5C%5C%5Cn%28B%29%3D68%5C%5C%5C%5Cn%28A%5Ccup%20B%29%3D110)
Using formula
![n(A\cup B)=n(A)+n(B)-n(A\cap B)](https://tex.z-dn.net/?f=n%28A%5Ccup%20B%29%3Dn%28A%29%2Bn%28B%29-n%28A%5Ccap%20B%29)
We have,
![110=55+68-n(A\cap B)\\\\\Rightarrow\ n(A\cap B)=123-110=13](https://tex.z-dn.net/?f=110%3D55%2B68-n%28A%5Ccap%20B%29%5C%5C%5C%5C%5CRightarrow%5C%20n%28A%5Ccap%20B%29%3D123-110%3D13)
Now, the number of students are involved in just sports is given by :-
![n(A)-n(A\cap B)=55-13=42](https://tex.z-dn.net/?f=n%28A%29-n%28A%5Ccap%20B%29%3D55-13%3D42)
Hence, 42 students are involved in just sports.

Answer: 4.2 miles
Step-by-step explanation:
So she ran 6 miles in 50 minutes how long will she run in 35 minutes?
So the equation will therefore be:
6=50
x=35
Cross multiply
6 x 35 = 50x
210 = 50x
Divide both sides by 50
The answer is 4.2 miles
Answer:
12 x 40 = 480 feet per minute.
480 x 60 = 28800 feet per hour.
28800/5280 = 5.45 miles per hour.
Hope that helps.Thank you!!!
