3
If you subtract for 4 from 7 in the first expression, then h is less than or equal to 3.
If you subtract 1 from 3 in the second expression then h is greater than 2.
Thus the only value of h possible is 3.
3pi/4 is 135 in degrees. A 135-degree angle lies in quadrant 2. In quadrant 2, the x values are negative and the y values are positive.
Assuming the number is 331/2, or 331 over 2:
331/2 = 165.5 ÷ 400 = .4138 x 100% = 41.38%
100% - 41.38% = 58.62% not nickels
If the number is 33 1/2, or 33 and one half
33 1/2 = 67.5 ÷ 400 = 0.0838 x 100% = 8.38%
100% - 8.38% = 91.62% not nickels
A = a^2
112 = a^2
sqrt 112 = a
sqrt 16 * sqrt 7 = a
4 sqrt 7 = a
so 4 sqrt 7 is the length of each side
