Answer:
40 problems in 100 minutes
Step-by-step explanation:
This is a ratio problem.
You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.
Answer:
(66.50) is the answer. Choose that one.
The answer is C, multiplication.
I think the answer is 2 because 1.5=1 1/2 so 1+1/2+1/2=2
Using the given exponential function, it is found that it will take 1.5 years for the amount of savings to double from the initial amount deposited of $1250.
<h3>Exponential function:</h3>
The <em>exponential function</em> that models the savings in the bank account is given by:

- In which t is the time in years that the money has been in the account.
The time to double from the initial amount deposited of $1250 is t for which S(t) = 2(1250) = 2500, hence:








It will take 1.5 years for the amount of savings to double from the initial amount deposited of $1250.
