Has infinitely many solutions.
In this case the answer is 1/4 because she makes 2 revolutions in 8 minutes. 2/8 = 1/4
14 + 16 + 18= 48 so the answer would be 14
Answer:
Hey there
<u>Step-by-step explanation: </u>
The sum of the integers from 1 to 620 is as follows: 192,510 To get the answer above, you could add up all the digits like 1+2+3... +620, but there is a much easier way to do it! Use the following formula: n(n + 1)/2 = Sum of Integers In this case, n=620, thus you get your answer by entering 620 in the formula like this: 620(620 + 1)/2 = 192,510
