While visiting Crimson Lake, Sally decided to go Kayaking. The rangers charge $8.50 per hour in addition to a $25.00 deposit to

salantis [7]

The total cost to rent the Kayak will be $50.50

Step-by-step explanation:

Let h be the number of hours

Given

Charges per hour = $8.50

Renting Charges = $25.00

The renting charges are constant and will be used only once while the per hour charges will be calculated as number of hours change.

The function will be written as:

$f(h) = 8.50h +25.00$

Here h is the number of hours.

From 11:30 AM to 02:30 PM makes three hours. So, to find the cost for 3 hours we have to put h = 3

$f(h) = 8.5(3) + 25.00\\= 25.5+25.00\\= 50.5$

Hence,

The total cost to rent the Kayak will be $50.50

Meg is 6 years older than Victor. Meg's age is 2 years less than five times Victor's age. The equations below model the relation

Verdich [7]

Since no possible correct method is posted, I will suggest a couple.

Method 1: guess and check

Works well for simple problems involving integers like this one.

Victor's age must be zero or greater than one, say one.

Guess v=1, find m=v+6=7, check m=5v-2=5-2=3 no good.

we need to make v bigger

Guess v=2, find m=v+6=2+6=8, check m=5v-2=5*2-2=8 ✔

So v=2, m=8.

Method 2:

Solve the system of two equations.

since the left-hand sides is m in both equations, and since m=m, we just have to equate the right-hand sides to solve for v.

5v-2=v+6

Solve for v

5v-v = 6+2

4v=8

v=2,

so again, v=2, m=v+6=2+6=8.

A sphere and the base of a cone have a radius of 3 inches. The volume of the sphere equals the volume of the cone. what is the h

Valentin [98]

So the volume of a sphere is $V= \frac{4}{3} \pi r^3$ , and the volume of a cone is $V= \pi r^2 \frac{h}{3}$ (h=height, r=radius). Knowing only the radius, we can solve for the volume of the sphere. (Also I'm going to be leaving answers in pi form.)

$V= \frac{4}{3} \pi 3^3$
Solve the exponents to get $V= \frac{4}{3} \pi 9$
Multiply 4/3 and 9 to get $V=13.5 \pi$

Now that we know the volume of the sphere, we can solve for the height of the cone since the volumes for both are the same.

$13.5 \pi = \pi 3^2 \frac{h}{3}$

Solve the exponents to get $13.5 \pi =9 \pi \frac{h}{3}$

Divide $9 \pi$ on each side to get $1.5= \frac{h}{3}$

Multiply 3 on each side, and your answer should be $4.5=h$
