Answer:
<h2>y=60+25h+0.3r</h2>
Step-by-step explanation:
let y be the total charges
given that the hour is h
and the cost for raw material is r
therefore
1. The first hour of service call = $60
2. For each additional hour= 25h
3. 30% over the cost of the materials.= 30/100*r=0.3r
total charges
y=60+25h+0.3r
therefore the expression is
y=60+25h+0.3r
I tried doing some equation hope it helps you a little
Answer:
152.4 cm
Step-by-step explanation:
Wesly is 5 feet and 3 inches tall. Since there are 12 inches in one foot, 5 feet has 60 inches. This means Wesly is 63 inches tall. If one inch is 2.54 cm then 60(2.54) is Wesly's height in centimeters. 60(2.54) = 152.4

Hello!</h2>
The answer is:
The airplane will travel 8800 feet in 10 seconds.
<h2>Why?</h2>
It's a conversion exercise, we need to be careful in order to solve it with no mistakes.
First:
We need to remember that 1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds, so, to calculate how many seconds are in one hour, we need to perform the following operation:

Second:
We need to convert from miles to feet, we need to remember that 1 mil is equal to 5280 feet.
So, solving we have:

Now, calculating how many feet does it travel in 10 seconds, we have:

We have that the airplane will travel 8800 feet in 10 seconds.
Have a nice day!
