Answer:

  • 71 and 19

Step-by-step explanation:

<u>Numbers are x and y, equations below:</u>

  • x + y = 90
  • x = 3y + 14

<u>Substitute x in the first equation:</u>

  • 3y + 14 + y = 90

<u>Solve for y:</u>

  • 4y + 14 = 90
  • 4y = 76
  • y = 19

<u>Find x:</u>

  • x = 90 - 19 = 71

The wheels of a monster truck are 66 inches tall. Find the distance the monster truck travels when the tires make one 360-degree
LuckyWell [14K]

Answer:

<u>207.35 inches</u>

Step-by-step explanation:

The wheel is in the shape of circle. The height, here, basically gives the diameter.

So,

Diameter = 66 in

Radius is half of diameter, so radius is:

66/2 = 33 inches

r = 33

Now, the distance truck travels when 1 rotation is made is the length of the perimeter of the circular wheel, or the circumference.

The formula is:

C=2\pi r

Where C is circumference

r is the radius

Substituting, we get the answer as:

C=2\pi r\\C=2\pi (33)\\C=66\pi\\C=207.35

The distance covered is about <u>207.35 inches</u>
