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

What is the median for the set of data shown

klemol [59]

Answer: OPTION C

Step-by-step explanation:

By definition, the median is the middle number in the set.

Therefore, keeping the definition above on mind, to solve this problem the numbers must be arranged from least to greastest. In the figure shown in the problem, you can see that they are already arranged in this order. Therefore, the middle number in the set is:

14, 28, 33, 42, 53, 81, 97

Then, you can conclude that the median is: 42.

Therefore, the answer is the Option C.

What is the quotient (x3 – 3x2 + 5x – 3) ÷ (x – 1)?

11111nata11111 [884]

Answer:

x^2 -2x +3
x^2 +2x +3

Step-by-step explanation:

The quotient in each case can be found by any of several means, including synthetic division (possibly the easiest), polynomial long division, or graphing.

1. The graph shows you the quotient is (x-1)^2 +2 = x^2 -2x +3.

2. The graph shows you the quotient is (x+1)^2 +2 = x^2 +2x +3.
