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

Answer:
8.1 * 10^-2
Step-by-step explanation:
Scientific notation is a number with it's largest digit in the one's place and its succeeding digits following it as decimals, then multiplied by a power of ten.
Appling this knowledge to the given number, we can conclude:
0.0810
= 0.081
= 8.1 * (1/10) * (1/10)
= 8.1 * 10^-1 * 10^-1
=9.1 * 10^-2
