Hobbs Mules charges $80 for a 2-hour mule ride and $144 for a 4-hour mule ride. The table down below shows how much McGee Mules
Nataliya [291]

Answer: If a group wants to take a 3 hour ride they should choose Hobbs Mules.

Step-by-step explanation:

First figure out how much a 3 hour ride at McGee Mules would cost. Do this by setting up a proportion, then solving it.

Numerator = Time       Denominator = Cost

\frac{1}{42} = \frac{3}{x}  42 x 3 = 126/1 = 126  So a 3 hour ride with Mcgee should cost $126.

Next figure out how much a 3 hour ride at Hobbs Mules would cost by doing the same thing.

\frac{2}{80} = \frac{3}{x}   80 x 3 = 240/2 = 120  So a 3 hour ride with Hobbs should cost $120.

In conclusion, The group should choose Hobbs because they price is $6 cheaper.

I NEED HELP EXPLAINING HOW I GOT MY ANSWER ILL GIVE 100 POINTS PLEASEEE?!?!?
attashe74 [19]

Answer:

<h2>h =  \frac{S - 2πr²}{2\pi r}</h2>

Step-by-step explanation:

S = 2πr² + 2πrh

<u>Move 2πr² to the left side of the equation</u>

That's

2πrh = S - 2πr²

<u>Divide both sides by 2πr to make h stand alone</u>

That's

<h3>\frac{2\pi rh}{2\pi r}  =  \frac{S - 2πr²}{2\pi r}</h3>

We have the final answer as

<h3>h =  \frac{S - 2πr²}{2\pi r}</h3>

Hope this helps you
