ThJennifers new bike cost $180. Her parents paid 40% of the costs and Jennifer paid the rest how much did Jennifer pay

Setler [38]

Answer:

Jennifer paid $108

Step-by-step explanation:

First you have to figure out how much Jennifer's parents paid. In order to do that you will have to do:

180 * 40 = 7,200 Then do: 7,200 / 100 which is 72 OR YOU CAN:

40 / 100 = .40 Then do : .40 * 72 which is 72

So Jennifer's parents paid $72.

So now you figured out how much Jennifer's parents paid, so to figure out how much Jennifer paid do:

180 - 72 which is $108.

This is how you know how much did Jennifer pay.

Austin takes 1 minute and 45 seconds to run three-quarters of a circular track. His rate of motion is π/ radians per second.

valentina_108 [34]

Length of circular track is:

L = 2*r*pi

He run 3/4 of it so length is:
L' = 3*2/4*r*pi = 3/2*r*pi

To calculate speed of his movement we use formula:
v = s/t where s = L' and t = 1 minute 45 seconds = 105 seconds

v = L'/t = $\frac{3*r*pi}{2*105}$

v = r* pi/70

If we take that r = 1 answer is $\pi /70$
