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.

. If FG = 7.3 meters, calculate the distance of IH .
Answer:
1.46m
Step-by-step explanation:
construction ; join EF
we know that EF is a radius, so EF = 5.3m
In triangle EFH,
∡EHF = 90° (EH is the perpendicular bisector of GF)
FH = FG/2 = 7.3m / 2 = 3.65m (EH is the perpendicular bisector of GF)
According to pythagoras theorem,
FH² + EH² = EF²
3.65² + EH² = 5.3²
EH² = 5.3² - 3.65²
EH² = 28.09 - 13.32 = 14.77m
EH = √14.77m
EH = 3.84m
EI is a radius, so EI = 5.3m
IH = EI - EH
= 5.3m - 3.84m
= 1.46m

(20 points, please help!) Using the diagram, what are the measures of angles 1, 2 and 3?
Answer:
angle 1 = 50°
angle 2 = 70°
angle 3 = 50°
Step-by-step explanation:
We know the top triangle equals 180 degrees.
angle 1 + 60 + 70 = 180
angle 1 + 130 = 180
angle 1 = 50
Because of parallel lines, we know that opposite angles will be equal.
What I mean by this is that angle 1 = angle 3 and angle 2 = 70 degrees.
angle 1 = 50°
angle 2 = 70°
angle 3 = 50°
-10x-2y=16 What is the slope intercept form of that?
Answer:
The slope is 5 and the slope or y intercept is 8 and the equation is y = -5x + 8.
Step-by-step explanation:
Turn it into -2y = 10x + 16
Then divide by -2
y=-5x+8
The slope is 5 and the slope or y intercept is 8 and the equation is y = -5x + 8.
Answer: y = 5x + 8
Step-by-step explanation:
-10x - 2y = 16 —> add 10x to each side
2y = 16 - (-10x) —> add the opposite & flip the numbers so the variable is closest to the equal sign
2y = 10x + 16 —> divide 2 by each side
y = 10x/2 + 16/2 —> simplify
y = 5x + 8

Harley and Natalie are each given 2 1/3 kg of clay Harley makes as many balls of clay as he can from his clay. Each ball weighs 1/6 kg. Natalie makes ten more clay balls than Harley (each weighing the same).
If Natalie used up all her clay, how much does each of her clay balls weigh?
Solution:
Note that:
One ball made by Harley = 1/6 kgEach student was given 2 1/3 kg of clayNatalie made 10 more balls (same weight) than Harley.Solving for how much balls made by Harley.
7/3 ÷ 1/6=> 7/3 x 6=> 7 x 2=> 14 balls.Solving for how much balls made by Natalie.
14 + 10 => 24 ballsFinding out the weight of each ball made by Natalie.
7/3 ÷ x = 24=> 7/3 × 1/x = 24=> 7/3x = 24=> 7 = 72x=> x = 7/72 kgNatalie's balls weigh about 7/72 kg.

Gas mileage is the number of miles you can drive on a gallon of gasoline. A test of a new car results in 510 miles on 20 gallons of gas. How far could you drive on 65 gallons of gas?
Answer:
The answer is 1,657.5 miles
Step-by-step explanation:
First divide 510 by 20 510 ÷ 20 = 25.5 into 65 = 1657.5
Given that test of a new car results in 510 miles on 20 gallons of gas. By unitary method, you can drive miles on 65 gallons of gas.
Unitary method is a method of solving a problem wherein to find the value of k units, you first calculate the value of one item, then multiply the value of the one item to k.
Given in the question,
distance covered in 20 gallons of gas = 510 miles
distance covered in 1 gallons of gas = [tex]\frac{510}{20} = 25.5[/tex] miles
distance covered in 65 gallons of gas = 25.5 * 65 miles = 1657.5 miles

A. Use the center of rotation point C and roatate point P clockwise around it 90°. The image is P'.
What is the coordinate of P'?
P'=( _ , _ )
B. With center of rotation point C and roatate point P' clockwise around it 90°. The image is P''.
What is the coordinate of P''?
P''=( _ , _ )
Answer:
A. P' = (9, -2)
B. P" = (1, -4)
Step-by-step explanation:
To make it easier to understand, make point C the origin (0 , 0). From that, you will notice point P is 3 units right and 5 units up of point C, meaning the coordinates of point P is (3, 5). A 90° rotation clockwise on point P (3, 5) is (5, -3). Since point C is 4 units right and 1 unit up from the actual origin, we will add that to (5,-3); (5 + 4, -3 + 1) = (9, -2). Therefore, P' = (9, -2).
Knowing the coordinates of P' allows us to figure out the coordinates of P''. Once again, we'll make point C the origin, meaning P' would be at (5, -3). Like we did before, we will perform a 90° rotation clockwise of (5, -3) to get (-3, -5). Lastly, add back the appropriate amount of units to (-3, -5) to make point C the center of rotation in this example; (-3 + 4, -5 + 1) = (1, -4). Therefore, P" = (1, -4).

A real estate builder wishes to determine how house size (House) is influenced by family income (Income), family size (Size), and education of the head of household (School). House size is measured in hundreds of square feet, income is measured in thousands of dollars, and education is in years. The builder randomly selected 50 families and ran the multiple regression. The business literature involving human capital shows that education influences an individual’s annual income. Combined, these may influence family size. With this in mind, what should the real estate builder be particularly concerned with when analyzing the multiple regression model?
When analyzing the multiple regression model, the real estate builder should be concerned with Multicollinearity.
What is Multicollinearity?This is a phenomenon in regression analysis where some of the independent variables are correlated. This can present an issue because the correlation leads to less reliable results.
The income in this research is influenced by the education and they both influence family size. There is therefore an issue of multicollinearity here because some variables are correlated.

Round your answer to the nearest hundredth digit.
Hence, section PL measures about 18.03 cm in length (rounded to the nearest hundredth digit).
what is length ?The length of a one-dimensional object, such as a line, curve, or straight segment, is measured by the fundamental physical quantity known as length. It is a way to gauge the separation between two points or the size of an object along a specific axis. The International System of Units (SI) uses metres as the unit of length (m). One of the most important ideas in geometry is length, which is used to describe the characteristics of geometric forms and shapes. For instance, the length of a circle is the distance around its circumference, whereas the length of a line segment is the distance between its endpoints.
given
(A) We must first determine the length of chord PQ in order to determine the length of segment PM. Since LM is the perpendicular bisector of PQ in the figure, PM is equal to MQ. PQ's length is 20 cm, so PM and MQ's lengths are each 50 percent of that, or:
PM=MQ=20/2=10 cm
Sqrt(PM2 + LM2) = PL
(d) When we enter the values from parts (a) and (c), we obtain:
Sqrt(10 + 15) = PL
Sqrt(100 + 225) = PL
Sqrt = PL (325)
PL ≈ 18.03 cm
Hence, section PL measures about 18.03 cm in length (rounded to the nearest hundredth digit).
