During a heavy rainstorm, a city in Florida received 12 1/2 inches of rain in 25 1/2 hours. What is the approximate rainfallrage
alexdok [17]
We need to divide the number of inches by the number of hours.
Let's first convert the two numbers into fractions.

12 1/2 = 25/2

25 1/2 = 51/2

(25/2) / (51/2) = 25/2 * 2/51 = 50/102 = 25/51 = 0.49

The average rainfall was approximately 0.5 inches per hour.

Use the GCF and the Distributive Property to express the sum as a product. 30 + 10
Inessa [10]

The expression that uses the GCF and the Distributive Property to express the sum as a product of the expression given as 30 + 10 is 10(3 + 1)

<h3>How to use the GCF and the Distributive Property to express the sum as a product?</h3>

The expression is given as:

30 + 10

Express the terms of the expression as the product of their GCF.

So, we have:

30 + 10 = 3 * 10 + 1 * 10

Factor out 10

30 + 10 = 10(3 + 1)

Hence, the expression that uses the GCF and the Distributive Property to express the sum as a product of the expression given as 30 + 10 is 10(3 + 1)

On a trip, you had to change your money from dollars to British pounds. You got 560 pounds for 800 dollars. How many pounds will
leva [86]
<h2>Answer</h2>

210 pounds

<h2>Explanation </h2>

First, we are going to find the exchange rate from dollars to pounds.

We know form our problem that 800 dollars are 560 pounds. so:

\frac{560pounds}{800dollars} =0.7 pounds per dollar.

Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:

300dollars*\frac{0.7pounds}{dollar} =210pounds

We will get 210 pounds for 300 dollars
