A ski slope is 320 yards long with a vertical drop of 100 yards. Find the angle of elevation of the ski run. Round to the nearest degree.

18°

Step-by-step explanation:

A ski slope is 320 yards long with a vertical drop of 100 yards. Find the

angle of elevation of the ski run. Round to the nearest degree.

The formula for angle of elevation is given as:

sin θ =Opposite/ Hypotenuse

Opposite = Vertical drop = 100 yards

Hypotenuse = Ski slope = 320 yards.

Angle of elevation =

sin θ = 100/320

sin θ = 0.3125

θ = arc sin(0.3125)

= 18.209956864°

Approximately = 18°

The total nom of  code that can be used is equal to 5+3 = 8

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

Volume of rectangular prism=length * width * height

Given,

length=3/8cm

breadth=5/8cm

height=7/8cm

therefore volume=(3/8)*(5/8)*(7/8)

                           =105/512 cm3

The solution is given below

Cost of 6 gallons =$15

Cost of 1 gallon =15/6

                           =$2.5

Cost of 7 gallons=$2.5 * 7

                           =$17.5
