Answers
Answer:
[tex]\$2229.4[/tex]
Step-by-step explanation:
Cost of 1 door = [tex]\$185.95[/tex]
Total number of doors = 4
Cost of 4 doors = [tex]\$185.95\times 4=\$743.8[/tex]
Cost of 1 window = [tex]\$148.56[/tex]
Total number of windows = 10
Cost of 10 windows = [tex]\$148.56\times 10=\$1485.6[/tex]
Total price of the doors and windows that needs to be purchased is [tex]\$743.8+\$1485.6=\$2229.4[/tex].

Answers
Answer:
no tengo ni idea
Step-by-step explanation:
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.
What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The coordinates of the triangle will be (x₁, y₁), (x₂, y₂), and (0, 0).
The length of the base of the triangle will be given as,
Base = (x₂ - x₁)
The height of the triangle is given as,
Height = (y₂ - 0) or (y₁ - 0)
Height = y₂ or y₁
The area of the triangle will be given as,
A = (1/2) × (x₂ - x₁) × y₁
A = (1/2) y₁(x₂ - x₁)
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.

A plumber charges his customers $25.70 per hour, h, plus a $54.50 service fee.On Tuesday,he earns $118.75 for fixing Mrs.Goodwill's sink. How long does it take the plumber to fix Mrs.Goodwill's sink
Answers
Answer:
2.5 hours
Step-by-step explanation:
Given that :
Charge per hour = 25.70
Service fee = $54.50
If total earning = 118.75 ; how many hours did it take to fix the sink?
Let number of hours = x
Total earning = service fee + (charge per hour * number of hours)
118.75 = $54.50 + (25.70x)
118.75 - 54.50 = 25.70x
64.25 = 25.70x
x = 64.25 / 25.70
x = 2.5
Hence, it took 2.5 hours to fix the sink

Step-by-step explanation:
If we put 65 over 100 and x over 34 and do cross multiplication, we see that 65 times 34 is 2,210. Dividing 100 from both sides of the equation, we divide 100 from x and 100 from 2,210. We are left with X = 22.1
