Answer:

10 hours

Step-by-step explanation:

The equation will change from f(t) = 1022 - 45t to 572 = 1022 - 45t. First subtract 1022 from both sides simplifying the equation to -45t = -450. Then, divide both sides by -45 to get the answer t = 10. Check your answer by putting it back into the equation. 572 = 1022 - 45(10) which goes to

572 = 1022 - 450 which goes to 572 = 572.

In a circle with an 8-inch radius, a central angle has a measure of 60°. How long is the segment joining the endpoints of the ar
g100num [7]
Given the radius, circumference can be solved by the equation, C = 2πr. The circumference of the circle above is C = 2π(8 in) = 16<span>π in. To solve for the length of the segment joining the arc is the circumference times the ratio of central angle and 360 degrees.

                          Length of the segment = (16</span>π in)(60/360) = 8/3 <span>π in

Thus, the length of the segment is approximately 8.36 in. </span>

A mountain bike originally priced at $960.00 is up for sale at a discount of 14%. What is the price of the mountain bike after t
PilotLPTM [1.2K]

Answer:

$825.60

Step-by-step explanation:

Since the price of it is $960.00, it means that it's 100%.

100% = 960

1% = 960 ÷ 100 = 9.6

14% = 9.6 x 14 = 134.40

Since they asked for after the discount, deduct the price of the discount with the original price.

Mountain bike after 14% discount =

960 - 134.40 = 825.60
