Answer:
8.9 in.
Step-by-step explanation:
Area of triangle = (1/2) b. h
40 = (1/2) x*x
80 = x^2
square root (80) = x
x=> 8.944.... inch
Rounding off you get 8.9 in.
No because adding the two fives will give you a 10 and 10 is greater than 3
$15.08 because $45.24 ÷ 3
72/4 = 18 (18)(2/3) = 12. The answer is $12.00 per hour
