There are 60 minutes in an hour, so to find the hourly rate, you would multiply 3.14 by 60, which gives us 188.4. If the rate is 188.4 gallons an hour, then we can divide 329 by 188.4. The full number would be 1.7462845011, but you can simplify that. If you need the minimum number of precise hours needed, then it would be 2. If you are allowed a small amount of error through simplifying your decimals, then you could say about 1.7.

a young tree grows 6 cm per year. use the equation height = 6 cm x number of years to find how many years the tree would take to
AnnZ [28]
The tree grows 6cm per year and we need to find out how long it will take to grow 1 meter. We know that 1 meter is equal to 100 centimeters. So:
6x = 100
x = 16.67
It will take 16.67 years (or one and two-thirds of a year) for the tree to reach 1 meter.

Korolek [52]

Caiden's balance after 5 years would be $831

<u>Explanation:</u>

Given:

Principal, p = $475

Rate of interest = 3.8%

time, t = 15 years

Balance after 15 years = ?

We know:

Amount, A = P(1+\frac{r}{n})^n^t

where,

n = number of compounding periods

r = rate of interest

t = number of years

Substituting the value;

A = 475(1+\frac{3.8}{100} )^1^5\\\\A = 831

Therefore, Caiden's balance after 5 years would be $831
