A 26 ft long ramp is used to reach 10 ft up a wall. The ramp covers a horizontal distance of 24 ft. To make the ramp less steep,
Anika [276]

Answer:

The length of new ramp is 49.03 ft.

Step-by-step explanation:

It is given that 26 ft long ramp is used to reach 10 ft up a wall. The ramp covers a horizontal distance of 24 ft.

If the horizontal distance is doubled, then the horizontal distance is 48 ft. The height remains same. Therefore the height of ram is 10 ft.

Use pythagoras in new right angle triangle.

hypotenuse^2=base^2+perpendicular^2

(AE)^2=(AD)^2+(ED)^2

(AE)^2=(48)^2+(10)^2

(AE)^2=2304+100

AE=\sqrt{2404}

AE=49.0306027\approx 49.03

Therefore the length of new ramp is 49.03 ft.

Dog up! franks is looking at a new sausage system with an installed cost of $500,000. this cost will be depreciated straight-lin
maxonik [38]
In this item, it is assumed that we are to calculate for the depreciation rate of the sausage system. This can be calculated through the equation,
     D = (P - S) / n

where D is the depreciation rate,
P is the present value of the sausage system, $500,000
S is the salvage value, $74,000
and n is the number of years, 5 years

Substituting the known values from the given in this item,
  D = ($500,000 - $74,000) / 5
  D = $85,200

The depreciation rate of the new sausage system that Frank will buy is $85,200/year
