7500 dollars is placed in an account with an annual interest rate of 5.25%. To the nearest tenth of a year, how long will it take for the account value to reach 25200 dollars?

After the amount will reach to .

Step-by-step explanation:

Given that,

                  Principle Amount

                  Rate of Interest %

                  Total Amount

Now,

        If Principle , Time years, Rate %

then, Amount after years

⇒

⇒

⇒

⇒

taking log both sides, we get

⇒

⇒

⇒

⇒

Therefore,

After the amount will reach to .

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
