Answer:
boys = 705
girls = 783
Step-by-step explanation:
We are to find the number of boys and girls in the school
the answer can be determined using simultaneous equation
x = boys
y = girls
y - x = 78 equation 1
y + x = 1488 equation 2
subtract equation 1 from 2
2x = 1410
x = 1410/2 = 705
Substitute for x in equation 1
y - 705 = 78
y = 705 + 78 = 783
radius = 15 in.
circumference = 94.2 in.
radius = diameter/2 = 30 in./2 = 15 in.
circumference = (pi)d = 3.14 * 30 in. = 94.2 in.
p ≥ 7/4
p +1/4 - (1/4) ≥ 2 - (1/4)
(-3)^2 = -3 x -3 = 9
(-2)^2 = -2 x -2 = 4
9 + 4 = 13
The answer is 13
