Answer:
2.3
Step-by-step explanation:
First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)

Answer: 24 days
Step-by-step explanation:
Sandy plays tennis once every 6 six days while Jim plays tennis once every 8 eight days.
To get the number of days they will play on the same day again, we find the lowest common multiple for the numbers.
The lowest common multiple is the smallest positive integer which is evenly divisible by both 6 and 8.
6 = 6, 12, 24, 30
8 = 8, 16, 24, 32
The lowest common multiple is 24.
In 24 days, they will play on the same day again
Answer:
0% of the racers finished in 28 minutes or less
Step-by-step explanation:
There is the need to understand the meaning of the standard deviation in this question.
The <em>standard deviation expresses by how much the finishing time differed from the mean/average time</em>. So, it tells us that the time range for all of the racers can be written as Mean ± Standard Deviation = 32 ± 2 minutes = (32 - 2) to (32 + 2) = 30 to 34 minutes.
So, all of the racers finished in 30 minutes or more, and no one finished in less than thirty minutes.
The questions asked to know o those who finished in 28 minutes or less, and that does not exist in this given data, so 0% of the racers finished in 28 minutes or less
