Answer:
445 dollars
Step-by-step explanation:
You are given he charges 47.5 per hour so 47.5x is how much you will pay for x hours and he charges a 65 dollar service fee.
So together he is charge you 47.5x+65 for x hours.
If it spends 8 hours, the cost will be 47.5(8)+65=445.
Answer:
r = 1
Step-by-step explanation:
Step 1: Write equation
-3r + 18 = 15r
Step 2: Solve for <em>r</em>
- Add 3r to both sides: 18 = 18r
- Divide both sides by 18: 1 = r
- Rewrite: r = 1
Step 3: Check
<em>Plug in r to verify it's a solution.</em>
-3(1) + 18 = 15(1)
-3 + 18 = 15
15 = 15
You can just use sine.
Sin(F) = opposite/hypotenuse = 28/40.
F =
(28/40)

Answer:
B: BC ≅EC
Step-by-step explanation:
You know that the two angles starting in C are congruent (they're opposite by vertex C).
Given that the B angle and the E angle are congruent, in order for the two triangles to be congruent by A(ngle)S(ide)A(ngle) you want the side inbetween to be congruent. That is BC and EC. Option B
