The tires on your bicycle have a diameter of 20 inches. How many rotations does each tire make when you travel 500 feet? Round your answer to the nearest whole number.

Answers

Answer 1

Answer: A tire is a circle, therefore:

1) we have to calculate the circumference of this circle (tire of this bycicle)
C=dπ
diameter=20 in
C=20π in.

1 rotation=20π in

2)we convert 500 ft to in
1 foot=12 in;

1 foot------------------12 in
500 feet--------------- x

x=(500 ft * 12 in) / 1 foot=6000 in.

3) Now, we calculate the number of rotations:
1 rotation=20π in≈20*3.141592654... in≈62.93 in,

1 rotation--------------62.93 in
x--------------------------6000 in

x=(1 rotatiton * 6000 in) / 62.93 in≈95.5 rotations≈96 rotations.

Answer: 96 rotations.

(0, 0) (3, −2) (−2, 3) (−3, 0)

Answers

(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.

(-2,3) wouldn't work with the second equation (2+3=5 not -5) so it's out. (0,0) is obviously out 0+0=0 same with (-3,0) -3+0=-3. The only one left is (3,-2) 3-2=1 and -3-2=-5. Since it's the only one to fit it's the correct option :)

B $ 12,000
C $ 15,360
D $ 19,200
E $ 24,000

Answers

Answer:

30,000 - 20% =24,000 year 1

24,000 - 20% =18,000 year 2

18,000 - 20% =12000 year 3

12,000 is your answer B)
