Guys I really need help, I don’t really understand so please help me, thanksss soooo much.

Answer 1

Answer:

0.08 inches

Step-by-step explanation:

a stack of 100 pennies is 6.1 inches tall.

that means 10 pennies is 0.61 inches tall.

a stack of 100 dimes is 5.3 inches tall.

that means 10 dimes is 0.53 inches tall

your answer is .61-.53 =0.08 inches

Answer 2

Since 10^2 pennies are 6.1 inches tall, we can find how tall are 10 pennies. 10^2=10*10=100, so 100 pennies are 6.1 inches tall, then 10 pennies are 6.1/10 inches tall, which is 0.61 inches. If 100 dimes are 5.3 inches tall, then 10 dimes are 5.3/10 or 0.53 inches tall. To find the difference, we can subtract the height of 10 dimes from 10 pennies, 0.61-0.53=0.08 inches.
