Answer: 2 and 17/20 mm is the total thickness of the stack.
Step-by-step explanation:
Get the values you need for the dime and the penny from the chart:
dime: 1 and 7/20mm , penny: 1 and 1/2mm
Find common denominators for the fractions given in the chart.
20 will work because 1/2 is the same as 10/20.
Add the numerators of the fractions: 7 + 10 = 17 so the fraction will be 17/20
Add the whole numbers 1 + 1 = 2
Put it all together and now you've got 2 and 17/20 mm
Answer:
Ethan's balance at the end of the week is of $273.75.
Step-by-step explanation:
Ethan starts the week with a balance of $275.00 in his checking account.
This means that B = 275.
During the week, he uses his debit card to spend $27.50 on food, $12.00 at the movies, and $6.75 for music downloads.
This is subtracted from the balance. So
B = 275 - (27.50 + 12 + 6.75) = 228.75
He earns and deposits $45.00 for mowing lawns.
Adds 45, so
B = 228.75 + 45 = 273.75
Ethan's balance at the end of the week is of $273.75.
