Starting from 300 feet away, a car drives toward you. It then passes by you at a speed of 48 feet per second.The distance d (in

feet) of the car from you after t seconds is given by the equation d=|300−48t|. At what times is the car 60 feet from you?

Combine like terms to get 2x + 6x which is 8x and 3y + 9y which is 12y so the simplified answer is 8x + 12y

A tire on a toy car has a diameter of 8 cm if the toy car travels 12,560 cm approximately how many times does the tire rotate? U

Marina86 [1]

Answer:

The number of rotations completed by tire = 500.

Step-by-step explanation:

The diameter of the tire of toy car = 8 cm

Now, DIAMETER = 2 x RADIUS

So, radius of the tire = D/2 = 8/2 = 4 cm

Now, Circumference of the Circle = 2πr

= 2 x 3.14 x 4 = 25.12 cm

Now, $\textrm{Total number of rotations} = \frac{\textrm{Total Area covered}}{\textrm{Area covered in 1 rotation}}$

= $\frac{12,560}{25.12} = 500$

The number of rotations completed by circle = 500.
