Answer:
12 quarters
20 dimes
Step-by-step explanation:
If all were dimes the value would be $3.20. It is $1.80 more than that. Each replacement of a dime with a quarter adds $0.15 to the value, so there must be $1.80/$0.15 = 12 such replacements.
There are 12 quarters and 20 dimes.
_____
Let q represent the number of quarters.
0.25q +0.10(32 -q) = 5.00 . . . . . total value
0.15q +3.20 = 5.00 . . . . . . . . . simplify
q = (5.00 -3.20)/0.15 . . . . . . subtract 3.20 and divide by 0.15
q = 12
Answer:
The arc length is 20.95 feet
Step-by-step explanation:
We calculate this using;
length of arc = theta/360 * 2 * pi * r
where theta is the central angle
So we have
length = 150/360 * 2 * 22/7 * 8
length = 20.95 feet
X + y = 52
x - y = 38
------------add
2x = 90
x = 90/2
x = 45
x + y = 52
45 + y = 52
y = 52 - 45
y = 7
ur numbers are 45 and 7
