Answer:
In 2 months, that cost is $80
Step-by-step explanation:
Option 1: after 2 months they will have paid 40 for set-up and 20*2 for cost per month so 40 + 40 = 80
Option 2: after 2 months they will have paid 0 for set-up and 40*2 for cost per month so 0 + 80 = 80
Answer:
D. 8 cm
Step-by-step explanation:
Reference angle = 60°
Opposite side = BC = 8√3
Adjacent side = AC = ?
Thus:
Tan (60) = opp/adj
Tan (60) = (8√3)/AC
AC*Tan(60) = 8√3
Divide both sides by tan (60)
AC = (8√3)/Tan(60)
AC = (8√3)/√3 (tan 60 = √3)
AC = 8 cm
B, because you keep trying to solve!
We know opposite angles in the parallelogram is congruent:
let x to be the unknown angle:
360=2(110)+2x
360=220+2x
140=2x
x=70
ECF is also 110 because of parallel lines and corresponding angles:
110+x+y=180
110+30+y=180
y=40
so DAE is 40
Answer:
Step-by-step explanation:
2y+3=5x-18
2y+21 = 5x
x = ⅖y + 21/5
