because of the word plus is addition

He rented the bike for 2 hours.

Step-by-step explanation:

Since a bike costs $13 plus $5 per hour, we can write this as:

13 + 5(h)

We used "h" as the variable for hours, since we need to find how many hours he rented the bike for, that he had to pay $23.

And since Pete paid $23, we need to make the other equation equal to 23.

= 23

So the actual equation, would look like this:

13 + 5(h) = 23

Now we just solve for h in the equation:

13 + 5(h) = 23

Step 1: Multipy 5 times "h"

13 + 5h = 23

Step 2: Subtract 13 from both sides

13 + 5h - 13 = 23 - 13

Step 3: Simplify

5h = 10

Step 4: Divide both sides by 5

5h/5 = 10/5

Step 5: Simplify

h = 2

So the number of hours that Pete rented the bike for 2 hours

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
