What percentage of a dollar is the value of each coin combination 1. 4 dimes
2. 1 nickel and 3 pennies
3. 5 quarters and 1 dime

1) 40%

2) 8%

3) 160%

Step-by-step explanation:

1) a dime is 10 cents. 10+10+10+10 = 40

.40/1.00 = 0.4 move the decimal to places to the right to turn into a percentage. 40%

2) 1 nickel is 0.05 cents and 3 pennies equal 0.03 cents. 0.05+0.03= 0.08 0.08/1.00=0.08

move the decimal to places to the right to turn into a percentage. = 8%

3) a quarter is 0.25 cents and a dime is 0.10 cents.

6 quarters = 0.25+0.25+0.25+0.25+0.25+0.25= 1.50

1.50 + 0.10= 1.60

1.60/1.00= 1.60 move the decimal to places to the right to turn into a percentage 160%

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
