The possible coordinate of point a is (6,4)
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:
x: C
y: A
z:
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is larger than either of the legs by a factor of 
. The length of x is therefore:
In a 30-60-90 triangle, the longer leg is larger than the shorter leg by a factor of 
. Therefore:
The hypotenuse of the 30-60-90 triangle is twice larger than the smallest leg, so it has a length of 
.
By the pythagorean theorem, you can find z+y:
