Step-by-step explanation:
a roofer charges $60 for the first hour of service call and $25 per hour for each additional hour. The roofer also charges a fee for all materials used plus 30% over the cost of the materials. Let r-roofer's cost of materials and h= number of hours worked. What expression could be used to find the cost of a service call
Answers
Answer:
y=60+25h+0.3rStep-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

Answers
Full question attached
Answer:
A. 230.4
B. 3.23
Explanation:
1. if 78.26% of murders are committed with firearms, 300 murders selected at random would be expected to have been committed with 300*0.7826= 230.4 firearms
2. To find how unusual this figure is, we find standard deviation from the mean 230.4
Standard deviation = x-u/N
=254-230.4/7.311= 3.23 rounded
Therefore 254 is unusual
7.311 is calculated √np(1-p)

Arianna runs up 4 flights of stairs and then runs down 4 flights of stairs does this situation represent additive inverses explain
Answers
It’s number 6. I’ll give brainliest
Answers
explanation:
we know that 2 CDs and 6 DVDs cost $156 and 1 CD and 9 DVDs cost $210.
this gives us the equations:
2x + 6y = 156
and
1x + 9y = 210
where x is CDs and y is DVDs
multiply the top equation by 9 and the bottom by -6 to solve for x:
18x + 54y = 1404
-6x - 54y = -1260
add from top to bottom:
12x = 144
divide both sides by 12 to get:
x= $12
