Dylan needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 5.5 hours and charged him $71 for parts. The total was $648.50. What was the cost of labor, per hour?
Answer:
$105 per hour
Step-by-step explanation:
$648.50 - $71 = $577.50
$577.50 / 5.5 = $105 per hour
105 x 5.5 = 575.50
+ 71.00
648.50
The per hour charge of the technician is given as $15.
What is the application ratio and proportion?A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.
Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.
The given problem can be solved by ratio method as follows,
The remaining cost charged by the technician is $648.50 - $71 = $577.50
Now, the per hour charge is remaining cost divided by total number of hours as given below,
577.50/5.5
= 57750/550
= 15
Hence, the cost of labor per hour is given as $15.

A) 80
B)-60
C) 2
D) -54
Step-by-step explanation:
which of the following would result in the same value as -40 divided by 2? select all that apply
Answer:
C D F
Step-by-step explanation:
Taking -40/2, we know our answer must be -20.
Testing each answer choice proves this.
A= 40*1/2, which is equal to 40/2, which is 20.
B= -40*-1/2, again, equaling 20.
C= 40/-2. Since one of our terms is negative, this one is -20.
D= 40*-1/2, again, -20.
E= -1/40*2. This would equal -2/40, using fraction multiplication.
F= -40*1/2, Which is the exact same thing the original question asks.
Thus, our final answer is C, D, and F.
The circumference of a circular rug is 24.8 meters. What is the area of the rug? Use 3.14 for π and round your answer to the nearest tenth.
Answer: 49.0 square meters
====================================================
Explanation:
We'll first need to find the radius of the rug using the circumference.
C = 2*pi*r
r = C/(2pi)
r = (24.8)/(2*3.14)
r = 3.949045 which is approximate.
Now we can find the area
A = pi*r^2
A = 3.14*(3.949045)^2
A = 48.968163 this is also approximate
Rounding to the nearest tenth gets to 49.0

A triangle has a base of 8 feet and a height of 6 feet. By how much does the height need to increase for the area to increase by 2 square feet? Write your answer as a decimal. plss help me
Answer:
0.5 ft
Step-by-step explanation:
Base = 8 ft and Height = 6 ft
Area of Triangle = 0.5*b*h
Area of Triangle = 0.5*8*6 = 24 sq.ft
To increase the Area by 2 sq.ft so the New Area will be 26 sq.ft
New Area = 0.5*b*(New Height)
26=0.5*8*(New Height)
New Height = 6.5 ft
The Increase in Height = New Height - Old Height = 6.5 - 6 = 0.5 ft
The increase in the height of the triangle which has a base of 8 feet and a height of 6 feet, to increase its area by 2 square feet is 0.5 feet.
How do we determine the area of a triangle?The area of a triangle is half the product of its base and its height, that is,
Area = (1/2)*base*height.
How do we solve the given question?We have been asked to find the increase in the height of a triangle with base(b) = 8 feet and height(h) = 6 feet, such that its area increases by 2 square feet.
First, we find the initial area of the triangle,
Area = (1/2)*b*h (1/2)*8*6 = 24 square feet.
New area = initial area + 2 square feet = 24 + 2 = 26 square feet
Let the increase in height be x feet,
∴ New height(h1) = 6+x feet
∴ New area = (1/2)*8*(6+x),
But we know that the new area is 26 square feet, so we equate them to get:
(1/2)*8*(6+x) = 26
or, 4(6+x) = 26
or, 24 + 4x = 26
or, 4x = 26 - 24 = 2
or, x = 2/4 = 0.5
∴ The increase in the height of the triangle which has a base of 8 feet and a height of 6 feet, to increase its area by 2 square feet is 0.5 feet.

The equation of the line passing through the points (–3, 11) and (1, –3) is 7x +2y = 1. Then the correct option is B.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The line JK passes through points J(–3, 11) and K(1, –3).
We know that the equation of a line passing through two points is given as
[tex]\rm (y - y_1) = \dfrac{y_2-y_1}{x_2-x_1} (x - x_1)[/tex]
Then we have

The amount of wheat exported by Canada on average is
approximately 2.21 × 107 tons per year. The amount of
wheat exported by Mexico on average is approximately
8.5 × 105 tons per year. How many times more wheat
does Canada export per year?
Based on the amount of wheat exported by Canada and Mexico, the number of times more wheat exported by Canada over Mexico is 0.26 times.
By how much more than Mexico, does Canada export wheat?This can be found by the formula:
= Amount of wheat exported by Canada / Amount of wheat exported by Mexico
Solving gives:
= (2.21 x 107) / (8.5 x 105)
= 236.47 / 892.5
= 0.26 times

Madeline uses this scale model of a design she plans to paint on a wall. She uses the key 1 cm = 1. 5 ft. One gallon of paint will cover 400 square feet of wall. How many gallons of paint will Madeline use? Enter your answer as decimal in the box.
The amount of paint required by Madeline will be 0.8325 gallons
What amount of paint will be required by Madeline?Given that
[tex]1cm=1.5ft[/tex]
We will first find the area of the wall
Area of the wall = Area of trapezoidal shape+ Area of triangular shape
Area of trapezoid = [tex]\dfrac{a+b}{2} \times h[/tex]
a= 4cm
b=14cm
h=10cm
putting this values
[tex]A=\dfrac{4+14}{2} \times 10[/tex]
[tex]A=90cm^{2}[/tex]
Area of triangular shape= [tex]\dfrac{1}{2} \times width\times height[/tex]
width=14cm
height=8cm
putting the values
[tex]A=\dfrac{1}{2} \times 14\times 8=58cm^{2}[/tex]
[tex]Total area of the wall= 90+58=148cm^{2}[/tex]
since we have
[tex]1cm=1.5ft[/tex]
[tex]148cm^{2} = 148\times (1.5)^{2} =333 ft^{2}[/tex]
Now
[tex]1gallon = 400ft^{2}[/tex]
so for [tex]333 ft^{2}[/tex] amount of paint in gallons required will be
[tex]1ft^{2} =\dfrac{1}{400} gallons[/tex]
[tex]333ft^{2} =\dfrac{333}{400} gallons=0.8325gallons[/tex]
Thus the amount of paint required by Madeline will be 0.8325 gallons
