A highway had a landslide, where 3,00 cubic yards of material fell on the road, requiring 200 dump truck loads to clear. On anot

Andru [333]

Answer:

2667 dump truck loads

Step-by-step explanation:

To solve this exercise, we must resort to a proportion rule.

Knowing what happened in the first place, how much was needed, a direct proportion will be made with the other accident, be as follows.

Landslide Dump Truck Loads

3 yd ^ 3 -------------------------------------------> 200

40 yd ^ 3 -------------------------------------------> X

X = (40 * 200) / 3

X = 2666.6, that is, for 40 cubic yards of sliding, approximately 2667 dump truck loads are needed.

A moving truck is rented at $1,000 per day plus a charge per hour of use. The moving truck was used for 9 hours one day, and the

Advocard [28]

1000 is our constant because the truck was only used one day. We also know they charge a certain amount per hour, but we do not know how much. In this case they charged that amount 9 times because the truck was used for 9 hours. The total of the constant plus the 9hour fee is 2700 dollars:

1000(1) + 9x = 2700

The reason we multiply 1000 by 1, is because we only used the truck for one day.

Solve for x

9x = 2700 - 1000 = 1700

X = 1700/9 = 188.88

The hourly fee is $188.88
The question is asking for an equation for hours of use though, so the answer is

1000(1) + 9(188.88) = C

C represents cost or charge.

Andre and Elena are each saving money. Andre starts with $100 in his savings

zysi [14]

Andre’s equation is y = 5x + 100 and Elena’s is y = 20x + 10
Andre - 5x + 100 the x is how many weeks (6) so it’ll be 5(6) + 100 which is 30 + 100 = $130 in 6 weeks
Elena - 20x + 10 same thing x is how many weeks (6) as well so 20(6) + 10 which is 120 + 10 = $130 as well in 6 weeks so therefore, the answer is C.
