Answer:
Anniversary sale price= $570
Step-by-step explanation:
Giving the following information:
Purchase cost= $400
Mar-up percentage= 90%
<u>First, we need to calculate the "normal" selling price:</u>
Selling price= 400*1.9= $760
<u>Now, we can determine the anniversary sale price:</u>
Anniversary sale price= 760 - (760*0.25)= $570
1/4 hour = 4 1/4 miles
Change to improper fraction:
1/4 hour = 17/4 miles
Multiply by 4 on both sides:
1 hour = 17 miles
Answer: Ramon rides his bike at 17 miles/hour.
Answer:
Correct option: C (it is missing the point)
0.53
Step-by-step explanation:
When a ball rolls one revolution, the distance travelled is the length of its circunference, that is:
Circunference = pi * diameter
So, to solve this question, we can use a rule of three:
1 revolution -> pi * d
60 revolutions -> 100 feet
100 = 60 * pi * d
d = 100 / (60 * pi) = 0.53 feet
Correct option: C (it is missing the point).
