Answer:
B) Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4
Step-by-step explanation:
A bicyclist rides the same number of miles every minute. The ratio table below shows the number of miles she rides during certain amounts of time.
Biking Times and Distances
Number of Minutes Number of Miles
10 2.5
16 4
? 7.5
48 12
Which statement explains how to find the number of minutes it takes to bike 7.5 miles?
B) Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4....
An easy way is to do it, if you get confused by multiplying fractions, is by turning the fractions into decimals. Since you are trying to find N you want to multiply the 1/5 by the 1/3.
1/5 = 0.2
1/3 = 0.33333333333333333333333333333333
if you multiply those you get 0.06666666666666666666666666666667 which when put into a fraction it equals 1/15
but if you don't want to do that just try to remember that you want to get by itself. and when multiplying fractions in this situation the bottom numbers only matter.. so 5 x 3 = 15 1/15
would you like me to put it in a document to show you?

Answer:
$56,558.1
Step-by-step explanation:
This is a question on compound interest.
The formula to calculate the Total Amount based on compound interest is given as:
A = P( 1 + r/n) ^nt
A = Total or Final amount in the account after t years
P = Principal/ Initial amount invested=$35,000
r = Interest rate = 12%
n = compounding Frequency = daily = using 30 days in a month = 30 × 12 = 360 days
t = time in years = 4
A = $35,000( 1 + 0.12/360)^360 × 4
A = $56558.08
Approximately to the nearest cent ≈ A = $56,558.1
Therefore, Priscilla should be expecting $56,558.1 in the account after 4 years.
