It rained 4.2 inches in 12 hours. At this rate,
how much will it rain in 27 hours?

9.45 inches

Step-by-step explanation:

We should make a proportion for this one.

4.2/12=x/27

Now we cross multiply.

12x=113.4

Now we divide both sides by 12.

x=113.4/12

We solve 113.4/12.

x=9.45 inches

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
