I think this is it x-y÷2=x+y÷4
The answer would be 80cm
All you have to do is multiply 10×8 to get the answer
25c(quarters) x 12 = $3.00
If theres 28 coins, and 12 are quarters, then that means theres 16 coins left to use for dimes.
10c(dimes) x 16 = $1.60
$3.00 + $1.60 = $4.60
Therefore, there are 12 quarters and 16 dimes.
Hope this helps! Feel free to ask any questions.
Answer:A≈314.16in²
Step-by-step explanation:
Unit Conversion:
d=20in
Using the formulas
A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·202≈314.15927in²
