X = 32 cause the numerator has to be 4 times bigger than the denominator

X/8 + 12 = 16
start by subtracting twelve from both sides
x/8 + 12 = 16
- 12 -12
You're left with x/8 = 4
Multiply both sides by 8
8× x/8 = 4 ×8
Your answer is x = 32
If you need to simplify, the answer is 2.

1. At the gym on Monday, Larry is told to up his weight on the bench-press by 15% from last week. Last week he was bench-pressin

QveST [7]

Answer:

300 lbs

Step-by-step explanation:

We know that Larry bench pressed 200 lbs last week, and that he is supposed to increase by 15%. We know that any number times one is that same numbers. That means a number that is increaseing has to be greater than 1. So, we have to convert 15% into a decimal. That is 0.15. That plus one is 1.15. Now we just have to multiply 1.15 with 200. We get 300.

The volume of a cylinder is 40 3. Which expression represents the volume of a cone with the same base and height as the

Novosadov [1.4K]

Answer:

$V_{cone}=\frac{1}{3} \,40\,\,ft^3$

Step-by-step explanation:

I believe you wanted to type that the volume of a cylinder is 40 cubic feet, and try to find what the volume of the same base and height would be in comparison.

Recall that the volume of a cylinder of base B and height H is given by the formula:

$V_{cyl}=B * H$

Recall as well that the volume of a cone of base B and height H is given by the formula: $V{cone}=\frac{1}{3} B*H$

Therefore, if the cone has the same base (B) as the cylinder, and equal height (H), then we can say that the volume of the cone is "one third" of the volume of the cylinder, which in Math terms is written as:

$V_{cone}=\frac{1}{3} \,V_{cyl}$
