Hi, here is the solution.
Ratio: The relationship between the two numbers of the same unit is called the ratio.
Example: The number of boys and girls in your class.
Rate: The rate is the ratio of two measurements that have different units.
Example: Miles per hour, working hours (40 hours per week)
Note: Rate is a special ratio.
Example
Sarah covered the distance of 60 miles in 3 hours. What is the rate per hour?
Rate = 60/3 = 20 miles per hour.
Hope you will understand this.
Thank you :)
Answer:
C.
Step-by-step explanation:
It is twice as the distance hope this helps!!
Answer:
Step-by-step explanation:
This may seem a bit tricky because we are not given enough info really to plug in and solve for the rate. We are told, however, that we are interested in doubling whatever amount we invested. So it is up to us to pick an amount for P, then double it for A(t). Let's use P = 1000 so A(t) = 2000. Filling in then:
and

We need to get that r all by itself and right now it's quite buried. Begin by dividing both sides by 1000 to get

Now take the 60th root of both sides to get

Subtract 1 from both sides to get
and multiply both sides by 12 to finally get the rate in decimal form:
r = .13943328
To get that in a percent form, multiply it by 100:
r = 13.9%
