Hi There!
Answer:
30 quaters.
15 dimes.
Step-by-step explanation:
Quarter = $0.25
Dime = $0.10
Quarters: 0.25 * 30 = $7.50

Hope This Helps :)
Answer:
The answer is -3,29
Step-by-step explanation:
Say the width is W and the length is L
L=3W (and of course W=W)
Now you use the perimeter formula P=2L+2W
80=2(3W) + 2W)
80=6W+2W
80=8W Divide both sides by 8
W=10
Now that you know the width, substitute it back into L=3W to find the length
L=3(10)
L=30
The dimensions are length: 30 cm and width: 10 cm
375 g. You have to set up a proportion and cross multiply.
