A car travels around a circular track of radius 1.5 miles. It traversed35of a complete revolution. Howfar did it travel?
Arturiano [62]

Answer:

The total distance traveled by the car is 330 miles.

Step-by-step explanation:

The circular track is the circumference of circle with radius 1.5 miles.

Circumference of a circle = 2\pir

Thus,

Circumference of the track  = 2 x \frac{22}{7} x 1.5

                           = 9.4286571429

Circumference of the track = 9.4286571429 miles

But, one complete revolution by the car is the circumference of the track.

i.e One complete revolution round the track = 9.4286571429 miles

Therefore,

35 complete revolutions round the track = 35 x 9.4286571429 miles

                                       = 330 miles

The total distance traveled by the car is 330 miles.

The length of a rectangle is three times it's width. The perimeter of the rectangle is 100 inches. What are the dimensions of th
Pavel [41]

Answer:

Dimensions : 37.5 * 12.5

length : 37.5

width : 12.5

Step-by-step explanation:

let x = length and y = width

x = 3y based on info from problem

Perimeter = 2(length + width)

100 = 2(x + y)

substitute 3y for x

100 = 2(3y + y)

100 = 2(4y)

100 = 8y

y = 12.5

x = 3(12.5) = 37.5
