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:
cool give it tome plz
Step-by-step explanation:
The distance between the two points would be the square root of 40. Hope this helped!
Answer: 100° and 80°
==================================
working:
supplementary angles = angle + angle = 180°
let the larger angle be x
smaller angle = (x/2) + 30
x + ((x/2) + 30) = 180°
(2x + x + 60) / 2 = 180°
3x + 60 = 360°
3x = 300°
x = 100°
Therefore the larger angle is 100°
smaller angle
= (100° / 2) + 30°
= 80°
Therefore, the two supplementary angles are 100° and 80°
