Answer: 80 quarters
55 nickels
Explanation:
Equation 1
q + n = 135
q = 135 - n
Also we know the dollar values: 0.25q + 0.05n = 22.75 ,call this equation 2
Substituting in equation 2, we get
0.25 (135-n) + 0.05n = 22.75
33.75 - 0.25n + 0 05n = 22.75
-0.25n + 0.05n = 22.75 - 33.75
-0.20n = -11
n = 11/0.20 = 55 = nickels
If q + n = 135
q = 135 - 55 = 80 = quarters

Answer:
The Jupiter ratio is 1: 5,719,360,000.
Explanation:
Since a basketball whose diameter is 25 centimeters represents the planet Jupiter, to find the scale (ratio) between Jupiter and the basketball, and then use this ratio to find the scaled diameter of the other planets, if Jupiter's diameter, 142,984 kilometers, is scaled to 25 centimeters, Saturn's diameter of 120,536 kilometers will be scaled to about 21 centimeters, the ratios are as follows:
1 centimeter = 0.00001 kilometers
25 = 0.000025
0.000025 = 142.984
1 = X
142.984 / 0.000025 = X
5,719,360,000 = X
Therefore, the Jupiter ratio is 1: 5,719,360,000.
Answer: 16.2-15.8/0.6=0.6667. Use normalcdf() to find the percentage from -999 to 0.6777 which is 0.7476*625=467
