Answer:
C.
Step-by-step explanation:
To find the volume of a cylinder the equation is pi times radius squared times height, the radius is half of the base so the radius is 2.5 inches so you have
pi(2.5)^2 h
Answer:
60 miles
Step-by-step explanation:
So if 1 inch = 12 miles, you need to find 4 inches. There are multiple ways to achieve this. However ratios/proportions might be easiest.
if 1/12 = 4/x, x is the value of miles. Cross multiply so you get this:
1 4
- = - = 60 = x
12 x
If x equals 60, that means that 4 inches equals 60 miles on the map.
You could also just find an equal fraction by multiplying the top and bottom both by 4.
The number is 2 :) because you need common denominators therefore you multiply by 3 so that 4 becomes 14 therefore 3 times 2 is 6 and 11 menus 6 is 4 so you get 4/14
Answer: C
Step-by-step explanation:
(fog)(3) is the same as finding f(g(3)). To solve, we first need to solve g(3). then, we solve for f(g(3)).
g(3)=5(3) [multiply]
g(3)=15
Now, we plug in 15 into f(x).
f(g(3))=-2(15)+8 [multiply]
f(g(3))=-30+8 [add]
f(g(3))=-22
Now, we know that C is the correct answer.
