It will be 20 because if the number next to it is 5 and above you will raise it to 21, but if the number is 4 or less, you don’t do anything. So therefore, the answer will be 20.

Ginny's piggybank contained $8.80 in quarters, dimes, and nickels. there were two more than five times as many nickels as quarte

SSSSS [86.1K]

Answer:

There are 13 quarters, 67 nickels, and 22 dimes.

Step-by-step explanation:

The value of a quarter is $0.25, the value of dime is $0.10, and the value of a nickel is $0.05. Let there be q quarters, n nickels, and d dimes.

Let's write equations from the statements given:

"Ginny's piggybank contained $8.80 in quarters, dimes, and nickels.":

$0.25q+0.1d+0.05n=8.80$

"there were two more than five times as many nickels as quarters":

$5q+2=n$

"4 less than twice as many dimes as quarters":

$2q-4=d$

Plugging in equation 2 and 3 into equation 1, we can solve for q:

$0.25q+0.1(2q-4)+0.05(5q+2)=8.80\\0.25q+0.2q-0.4+0.25q+0.1=8.80\\0.7q=8.80+0.4-0.1\\0.7q=9.1\\q=\frac{9.1}{0.7}=13$

Substituting q = 13 into equation 2 will give us nickels:

$n=5q+2\\n=5(13)+2\\n=67$

Substituting q = 13 into equation 3 will give us dimes:

$d=2q-4\\d=2(13)-4\\d=22$

There are 13 quarters, 67 nickels, and 22 dimes.

How can I find the unknown side lengths when given the area or circumference of a figure?

ad-work [718]

Answer:

Set up the area/circumference equations using x as the unknown variable. Then, solve for that variable and apply the correct unit.

Step-by-step explanation:

For example,

Find the side length of a square with an area of 49 square centimeters.

Since $area=s^{2}$ , i can write $49=s^2\\then take the square root of each side to solve for s.\\s=\sqrt{49} \\s=7 centimeters$

On a certain day, the exchange rate was 60 U.S. dollars for 50 euro. How many U.S. dollars were 60 euro worth that day?

Fudgin [204]

The exchange rate can be expressed as: 60 dollars / 50 euro

So 60 euros * 60 dollars / 50 euro = 60 * 60 / 50 dollars (the euros cancel out)
= 3600 / 50 dollars
= 360 / 5 dollars
= 72 dollars
