Answer:
3/2
Step-by-step explanation:
Apply exponent rule: a^-1 = 1/a
(2/3)^1 = 1/2/3
Apply the fraction rule: 1/a/c = c/b
3/2
Answer:
109.9 feet
Step-by-step explanation:
To find how many feet has Miguel traveled, we need to know the circunference of the tire:
C = pi*d = 3.14 * 28 = 87.92 inches
So, for each revolution of the tire, Miguel will travel 87.92 inches. So, to know the distance he will travel, we can do a rule of three:
1 revolution -> 87.92 inches
15 revolutions -> x inches
1/15 = 87.92/x
x = 87.92 * 15 = 1318.8 inches
As the question asks for the distance in feet, we convert from inch to foot by dividing the value of inches by 12, so:
distance in feet = 1318.8 / 12 = 109.9 feet
Answer: 24 students
Explanation:
(20 + 23 + 25 + 28)/4
= 96/4
= 24
Therefore the mean is 24 students in the class.
