Answer:
343 cubic in.
Step-by-step explanation:
To find the value of a rectangular prism (which is a box), we multiply the length, width, and height of the prism together. In this case, we know that they are all 7 because that is given. Therefore, the volume is 7 * 7 * 7 = 343 cubic inches. Hope this helps!
Answer:
Your answer would be A
Step-by-step explanation:
Okay, so. We know they lost 320 dollars but then they earned 126 dollars, profit means they earned it. So, we know it won't be B, because it does not shows they lost any money, it could be C, it could be A, but it is not D. So, then we look at A and C. We then notice 126 has a negative sign and A does not, we know that then it is going to be A. Also, if you need to know how much more money they are in debt. This is what you do.
-320 + 126 = -194
You would add the negative into the positive.
Hope this helps!
Answer:
x^2 -2
Step-by-step explanation:
f(x) = x^2 -3
g(x) = x+1
Put f(x) in for x in the function g(x)
g(f(x)) = f(x) +1 = x^2 -3+1 = x^2 -2
Answer:
3 gallons of paint
Step-by-step explanation:
Various data is missing, but I think it can be solved with the following assumptions:
The first thing is to assume that 12 gallons was the exact amount needed for the two rooms.
If so, we can say the following where x is the size of the smallest room:
Room 1: It is 2 * x and needs 3 coats of paint, so there would be 6 * x left
Room 2: is x and uses 2 coats of paint therefore 2 * x
The paint sum would be as follows:
6 * x + 2 * x = 8 * x
8 * x = 12
x = 12/8 = 3/2
So:
Room 1: 6 * 3/2 = 9, 9 gallons of paint needed
Room 2: 2 * 3/2 = 3, 3 gallons of paint needed
Room two is the unpainted one so 3 gallons of paint was returned.
