Answer:
C) 3 cm , 4 cm , 5 cm
Step-by-step explanation:
Using process of elimination and Pythagora's Theorem, find which of the smaller sides, when their squares are found equal to the largest number squared.
A, B, & D are wrong because:
A: 4 + 4 ≠ 16
B: 9 + 25 ≠ 100
D: 16 + 64 ≠ 225
BUT CON THE OTHER HAND 9 + 16 = 25
The answers are 2/1, 5/3, and 7/1.
Y = 12x + 115....where x is the number of hrs and y is the number of fans
an order for 500 fans...
500 = 12x + 115
500 - 115 = 12x
385 = 12x
385/12 = x
32.08 rounds to 32.1 <=== it would take 32.1 hrs
