Answer: 0.9
Step-by-step explanation:
<u>Let x be the number</u>
<u>Determine the value of the number</u>
x² = 81
√x² = √81
x = 9
<u>Find the 10% of the number</u>
Final number = rate of percentage × original number
Final number = 10% × 9
Final number =

Answer:
B
Step-by-step explanation:
The distance of a run compared with the number of times around a track.
The question asks for what is most likely to have a constant rate of change. This means that for every x, there is about the same y, as a constant rate of change means that there is a consistent slope, which is the x and y value. In real world terms, it means that you can expect every one value to change however much without changing randomly.
For example, when you buy a pizza, you expect a pizza to get you 8 slices. When you get two, you expect to get 16, 3 gets you 24 slices, and so on. This expectation is based off the constant rate of change, as you get 8 slices for each pizza. The slices would be modeled as y and the pizza would be modeled as x in mathematical terms in this situation.
Because we know that the track's distance doesnt change with every lap, we can expect it to have a constant rate of change. This concept is the same as the pizza as discussed earlier. Every lap would get her a certain amount of miles, and every other lap would increase the same amount.
Answer: 1/50
Step-by-step explanation:
0.020 = 20/1000 = 1/50
Well i think it would be 10 because 10 divided by 5=2
