The answer is 21. 75²=5625 72²=5184 5625-5184=441 √441=21 so 21 is your answer. I hope this helps. The formula to figure out the hypotenuse A²+B²=C² can also be used to find a leg. Since we have one leg and the hypotenuse I was able to figure this out.

A coin collector has $45 in just dimes and quarters in a piggy bank he counted all the coins and there are 240 total how many ea
Whitepunk [10]

Answer:

The number of <u>dimes are 100</u> and number of <u>quarters are 140.</u>

Step-by-step explanation:

Let the number of dimes be 'd' and quarters be 'q'.

Given:

The sum of amount is $45.

The total number of coins are 240.

1 dime = $0.10

∴ 'd' dimes = \$0.10d

1 quarter = $0.25

∴ 'q' quarters = \$0.25q

Now, as per question:

d+m=240-----1\\0.1d+0.25q=45---2

Multiplying equation (1) by -0.1 and adding the result to equation (2), we get:

-0.1d-0.1q=240\times -0.1\\-0.1d-0.1q=-24\\0.1d+0.25q=45\\-----------\\0.15q=21\\q=\frac{21}{0.15}=140\\\\d=240-q=240-140=100

Therefore, the number of dimes are 100 and number of quarters are 140.
