Jessica and Brad are both solving 3.65 divided by 100. Jessica says the answer is 365. Brad says the answer is 0.0365. Which student is correct?

Brad

Step-by-step explanation:

3.65 / 100 = 0.0365

Another way to figure out the answer is by moving the decimal point two times to left ( division goes left, multiplicatin goes right)

If you move the decimal point to left 2 times in 3.65, you will get 0.0365

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
