Piere is an electrician
He uses this formula to work out the amount ,$c , to charge for a job that takes ×hours
C=20+30×
He starts a job at 9 30 and finishes at 1 pm
Work out his charge for this job
Pls show me formula
Answer:
c=$125
Step-by-step explanation:
9:30--12:30 is three hours, then another half hour till 1pm total hours is 3.5
c = 20+30*3.5
c=20 + 105
c = 125
The charge for Piere's work is $125 by using the formula C = 20+30x.
What is a linear equation?A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. An equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For the given situation,
Let the amount in dollar,$ be C.
Let the hours be x.
The equation is C = 20+30x.
He starts a job at 9:30 and finishes at 1 pm. So, the time x is 3.5 hours.
⇒ [tex]1pm-9:30 am=3.5 hours[/tex]
Thus charge for the electrician is
⇒ [tex]C=20+30(3.5)[/tex]
⇒ [tex]C=125[/tex]
Hence we can conclude that the charge for Piere's work is $125 by using the formula C = 20+30x.

A furniture store pays a wholesale price for a mattress.
Then, the store marks up the retail price to 150% of the
wholesale price. Later, they put the mattress on sale for
50% off of the retail price. A customer just bought the
mattress on sale and paid $1,200.
a. What was the retail price of the mattress, before the
discount?
Answer:
Step-by-step explanation:
Part A:
Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then
50% of x = 1200
⇒ 0.5x = 1200
⇒ x = 1200 / 0.5 = 2400
Therefore, the retail price of the mattress, before the discount is $2,400.
Part B:
Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then
(100% + 150%) of p = 2400
250% of p = 2400
2.5p = 2400
p = 2400 / 2.5 = 960.
Therefore, the wholesale price, before the markup was $960

4p = 14.4
What is the value of p?
A. 3.6
B 3.8
C.10.4
D.57.6
Answer:
A. p = 3.6
Step-by-step explanation:
4p = 14.4
To get p by itself we would divide by 4 on each side so
(4p / 4) = (14.4 / 4)
p = (14.4 / 4)
p = 3.6
So answer is A

Which equation has a slope of 3?
y=3y is equal to 3
y=3−xy is equal to 3 minus x
y=3x−1y is equal to 3 x minus 1
y=x+3
Answer:
the third one
Step-by-step explanation:
slope intercept form is y = mx + b
where m = slope
for the third one m = 3
therefore the third one is the correct answer

2. Find the unit rate demonstrated in the graph
below.
A. 9 miles per hour
B. 4.5 miles per hour
C. 3 miles per hour
D. 1.5 miles per hour
The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.
What is the rate?The rate is the proportion of how much something is to the unit. For instance - Assuming that the speed of the vehicle is 20 km/h it implies the vehicle voyages 20 km in 60 minutes.
The incline is the proportion of rising or falling and running. The contrast between the ordinate is called rise or fall and the distinction between the abscissa is called run.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
From the graph, take two points from the graph which are (0, 0) and (27, 6).
Then the unit rate demonstrated in the graph will be given as,
Rate = (27 - 0) / (6 - 0)
Rate = 27 / 6
Rate = 4.5 miles per hour
The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.
More about the rate link is given below.

Using the dimensions shown, you could create a rectangular prism. Caculate the surface area for the rectangular prism. A 30m2 b 56m2 c 60m2 d 112m2
Answer:
550ft²
Step-by-step explanation:
Since we are not given the dimension of the rectangular prism. Let us assume;
Length of the rectangular base L = 10ft
Width of the rectangular base W = 15ft
height of the prism H = 5ft
Total surface area of the prism = 2(LW + WH + LH)
Substitute the given values
Total surface area of the prism = 2{10*15 + 15*5 + 10*5}
Total surface area of the prism = 2(150+75+50)
Total surface area of the prism = 2(275)
Total surface area of the prism = 550ft²

Find the value of x, image attached below
Answer:
x = 10
Step-by-step explanation:
Sum of angles in a triangle is 180° , so
35° + (5x + 7)° + (9x - 2)° = 180°
The value of x can now be found by solving the linear equation.
5x + 9x + 35 + 7 - 2 = 180
14x + 40 = 180
14x = 180 - 40
14x = 140
x = 140/14
x = 10

Michael has $68. Craig has $24 less than Michael has. Michael spends $20 on a new hat. Part A: Write an equation where the solution represents the amount of money (x), in dollars, Craig has after Michael buys the hat. Explain how you came to this equation. Part B: Now, Craig buys some socks. He has $16 left. Write an equation where the solution represents the amount of money (y), in dollars Craig spent on socks. Show how you know this is the correct equation.
Answer:
a) x + 4 = 48
b) y + 16 = 44
Step-by-step explanation:
a) Michael has $28 and Craig has $24 less than Michael. Let x represent the amount of money that Craig has. Hence:
x = 68 - 24
x + 24 = 68
Given that Michael spends $20 on a new hat. Therefore we subtract 30 from both sides of the equation:
x + 24 - 20 = 68 - 20
x + 4 = 48
x = $44
b) If y represent the amount of money that Craig spent on buying socks. He has 16 remaining.
Therefore:
44 - y = 16
y + 16 = 44
y = $28
Given the definitions of f(x) and g(x) below, find the value of g(f(5)).
f(x) = 2x – 10
g(x) = x^2 + 6x – 8
I don’t need work I am just looking for the answer !
gf(x) = g(x^-1) = x^2 + 6x - 8
f(x) = 2x - 10
gf(x) = 6 ( 2x - 10) - 8
gf(x) = 12x- 60 - 8
gf(x) = 12x -68
gf(5) = gf(x) = 12x - 68
gf(5) = 12(5) - 68
gf(5) = 60 - 68
gf(5) = -8
