1- The answer is that she wants the new time to be 32 minutes

Solution: The question asks that she wants to DECREASE by 20%

What you will do it convert 20% to a decimal (which is 0.20)

Then, you need to multiply the minutes by the decimal:

40 x 0.20 = 8 minutes

Now you know that 8 minutes will be 20% of 40 minutes, so you just subtract 8 from 40 UwU

jenyasd209 [6]

Answer:

11 years.

Step-by-step explanation:

Given that Carter invested $ 16,000 in an account paying an interest rate of 5.6% compounded monthly, to determine, assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $ 29,600, the following calculation must be performed:

16,000 x (1 + 0.056 / 12) ^ Yx12 = 29,600

Y = 11

16,000 x 1.4666 ^ 132 = X

29,581.70 = X

Thus, rounded to the nearest year, it would take 11 years for the account to reach $ 29,600.
