A thrill ride at an amusement park travels 55 miles per hour. To the nearest hundredth, how many feet per second is this?

1 answer:

3 0

The first thing you should know are the following conversions:
1mi = 5280 feet
1h = 3600 s
Applying the conversions we have
(55) (miles / hour) (1/3600) (h / s) (5280/1) (feet / mi) = 80.67feet / s
answer
this is 80.67feet / s

Answer: 1) D 2) B

Step-by-step explanation:

1) The denominator cannot equal zero, Factor the denominator to find the zeros. n³ - 4n² + 3n = 0

n(n - 3)(n - 1) = 0

n=0 n-3=0 n-1=0

n=0 n=3 n=1

2) In order to be a rational expression, it must be in the form $\dfrac{a}{b}$ where both a and b are integers.

Since $\sqrtb$ $\sqrt b$ is irrational and not an integer, then the expressions containing an irrational term after simplified cannot result in an integer.
