Answer: their is no x?
Step-by-step explanation:
Answer: Y= 3/2x-8=
Step-by-step explanation:Y=4 M= 3/2. X=-8
Y=mx+b
4 = 3/2(8)+b
4= 24/2+b
4= 12+b
-12=-12
-8=b
The cost for the contractor to have all the dirt hauled away for a foundation of 12 feet long, 9 feet wide and 6 feet deep is $720
<h3>Volume of rectangular prism</h3>
volume of a rectangular prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
l = 12 ft
w = 9 ft
h = 6 ft
volume of the foundation = 12 × 9 × 6
volume of the foundation = 648 ft³
Therefore, the contractor pays $180 per load for the trucks remove the dirt.
648 cubic feet = 24 cubic yard
6 cubic yards = 1 truck load
24 cubic yard =
cross multiply
number of truck load = 24 / 6 = 4 truck loads
Hence,
1 truck load = $180
4 truck load =?
cross multiply
cost = 4 × 180 = $720
