Answer:
9
Step-by-step explanation:
We're using the Pythagorean theorem here since it's a right triangle.
a^2 (side) + b^2 (side) = c^2 (hypotenuse)
12 = a
x = b
15 = c
12^2 + b^2 = 15^2
144 + b^2 = 225
- 144 - 144 (subtracting 144 from both sides to isolate b)
b^2 = 81
(getting rid of the exponent by squaring both sides)
b = 9
x = 9
Answer:
21x +30
Step-by-step explanation:
7 (3x + 6)-12
Distribute
21x + 42 -12
Combine like terms
21x +30
15 hrs a week at 8.95 per hr = (15 * 8.95) = 134.25 gross pay
FICA (7.65%)....0.0765(134.25) = 10.27
fed.tax (9.3%)...0.093(134.25) = 12.49
state tax (5.8%)..0.058(134.25) = 7.79
total taxes : 10.27 + 12.49 + 7.79 = 30.55
savings account money = 30
134.25 - (30.55 + 30) =
134.25 - 60.55 = 73.70...its gonna be the last one because I did a little rounding up above
Answer:
b. 45
why?
because the diagonal line intersects both AB and CD at the same angle
