Answer:
Step-by-step explanation:
Let the number of month be x
<u>Expression to show amounts</u>
- 2350 + 200x = 3250 + 175x
- 200x - 175x = 3250 - 2350
- 25x = 900
- x = 900/25
- x = 36
<u>Amount</u>
- 2350 + 200*36 = 2350 + 7200 = 9550
Time is 36 months
Amount is $9550
The ideal mechanical advantage of a slope is given by the ratio between the output load, which is simply the weight of the object (), and the input force applied to move the object along the slope:
The energy conservation law states that the potential energy of the object when it reaches the final height h is equal to the work done to move the object along the distance of the slope , i.e.
From this we find
Therefore, we can substitute this into the formula of the ideal mechanical advantage and calculate its value:

Given:
Temperature at the bottom of the mountain is 74°F
The top of the mountain is 5500 feet above you
Change (reduction) in temperature is 3.3 X 5500 / 1000
= 18.15°F
Temperature at the top of the mountain is 74°F – 18.15°F
= 55.85°F
