Answer:
radius = 14.5 feet
Step-by-step explanation:
91.06 / 3.14 = diameter = 29
radius = 29/2 = 14.5 feet
I got you fam
2(x - 4) - 4x = 0
2x - 8 - 4x = 0
-2x - 8 = 0
-2x -8 + 8 = 0 + 8 (add 8 both sides)
(divide both sides by -2)
x = -4
Hope this helps
Answer:
a
Step-by-step explanation:
y = 3x - 7 → (1)
4x - 5y = - 20 → (2)
substitute y = 3x - 7 into (2)
4x - 5(3x - 7) = - 20
4x - 15x + 35 = - 20
- 11x + 35 = - 20 ( subtract 35 from both sides )
- 11x = - 55 ( divide both sides by - 11 )
x = 5
substitute x = 5 into (1)
y = 3(5) - 7 = 15 - 7 = 8
solution is (5, 8 )
Answer:

Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and the exact values
sin60° =
and cos60° =
, then
sin60° =
=
=
=
( cross- multiply )
2BC = 10
( divide both sides by 2 )
BC = 5![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
------------------------------------------------------------------------
cos60° =
=
=
=
( cross- multiply )
2AB = 10 ( divide both sides by 2 )
AB = 5
