Answer:
three-fifths over three-eights equals one and three-fifths miles per hour
Step-by-step explanation:
- The martinez family walked three over five of a mile; this means they walked 3/5 of a mile.
- They walked such distance in in three over eight of an hour, this means 3/8 of an hour.
To find the rate in miles per hour, we have to divide 3/5 divided 3/8.
TO make division of fraction, we must invert the second fraction and multiply them:
The ratio is 8/5 miles per hour. In the answer given it is expressed as a mixed numer 1 3/5 that is equal to 8/5.
To transform a fraction to a mixed number, you have to divide numerator by denominator. Explanation is in figure attached.
Answer:
a. 22.08
Step-by-step explanation:
d = diameter = 15ft; r = (1/2)d = 7.5ft; A=area
So, A = (π) ×
A = (π) ×
A = (π) ×
The entire circle is 360°, so 45 is .
A(slice) = ×
π
A(slice) = 7.03 × (π) ×
