Step-by-step explanation:
Francisco needed to get his computer fixed. He took it to the repair
store. The technician at the store worked on the computer for 5 hours
and charged him $176 for parts. The total was $651. Write and solve an
equation which can be used to determine x, the cost of the labor per
hour.
Answer:
$95 per hour
Step-by-step explanation:
The total of charges is the sum of the cost of labor and the cost of parts. The cost of labor is the product of hours (5) and the cost per hour (x). Then the equation for total cost is ...
total cost = parts cost + hours cost
651 = 176 + 5x
475 = 5x . . . . . . . subtract 176
95 = x . . . . . . . . . divide by 5
The cost of labor per hour is $95.

The line is a vertical line, thus, the slope is not defined.
What is the slope of the line that passes through the two given points?If we know that a line passes through two points (a, b) and (c, d), then the slope is given by the expression:
slope = (d - b)/(c - a)
Here we have the two points (9, 2) and (9, 27)
So the slope is:
slope = (27 - 2)/(9 - 9)
That tends to infinity, and this happens because this is a vertical line. So the slope is undefined.

Evelyn watches airplanes take off at an airport. She is 200 meters away from where the planes take off from the runway. The initial angle at takeoff of a plane is 12°. A triangle is shown. The triangle is made up of the initial takeoff of the plane, where the plane currently is in the sky, and where Evelyn is watching the plane. The angle of takeoff is 12 degrees. The distance from the initial takeoff to Evelyn is 200 meters and the distance from the initial takeoff to the plane apostrophe s current position is 100 meters. What is true when the plane is 100 meters away from takeoff? Check all that apply. The given information is the SSS case. The given information is the SAS case. The given information is the SSA case. Evelyn is approximately 104 meters from the plane. The angle of elevation of the plane is 12°.
Two triangle are congruent when the shape and size of both the triangle are same.
The given information is the SAS case. Thus the option B is the correct option.
What is triangle congruence theorem?Two triangle are congruent when the shape and size of both the triangle are same.
Triangle congruence theorem are-
Angle-Side-Angle theorem (AAS)- This theorem states that two triangle is congruent when two angle and one side of the triangle are respectively equal to the two angles and same side of the other triangle.Side-Side-Side theorem (SSS)- When the three sides of the one triangle is equal to the three sides of the other triangle respectively, then the triangle are congruent. Side-Angle-Side theorem (SAS)- Two sides and the included angle of are equal to the two sides and one angle of other triangle respectively.Given information-
The distance of the Evelyn from the airplane is 200 meters.
The initial angle at takeoff of the plane is 12 degrees.
Evelyn is approximately 104 meters from the plane.
The angle of elevation of the plane is 12°.
The triangle made for this situation is attached below.
As in the shown triangle below this question. The distance of Evelyn from the initial takeoff of the plane is shown.
This distance is equal to the base of the triangle. Therefore we get the one side of the tingle.
Now the plane is flied 100 meters, which gives the value of another side of the triangle as shown in the image below attached.
Angle of elevation of the plane is 12 degrees, which gives the one angle of the triangle.
Thus we have one side equal to the 100 meters, one angle equal to the 12 degrees and another side with equal to the 200 meters.
Thus it is the case of side angle side.
Hence, the given information is the SAS case. Thus the option B is the correct option.

Answer:
The correct answer would be options B. D. and E.
Step-by-step explanation:
Just got this correct on edge. - hope this helps!
Brainliest would be greatly appreciated :)
calculate the value of x in each case
First taking small triangle,
Perpendicular(P') = 5cm
Base(B) = y (let)
Hypotenuse(H') = 12cm
so,
(H')² = (P')² + (B)²
(12)² = (5)² + (y)²
(y)² = 144 - 25
(y)² = 119
Now taking big triangle,
Perpendicular (P) = 12+5 = 17cm
Base (B) = y (already supposed)
Hypotenuse (H) = x
so,
(H)² = (P)² + (B)²
(x)² = (17)² + (y)²
(x)² = 289 + 119 = 408
x = √408

Bob is thinking about leasing a car. The lease comes with an interest rate of 8%. Determine the money factor that will be used to calculate Bob’s payment. A. 0. 00033 b. 0. 00192 c. 0. 00333 d. 0. 1920.
The money factor will be used to calculate Bob’s payment is 0.0033.
Given
Bob is thinking about leasing a car.
The lease comes with an interest rate of 8%.
How to calculate the money factor?The money factors can be converted to interest rates by multiplying by 2,400.
In the same vein, if the car dealer uses an interest rate, this can be converted to a money factor by dividing by 2,400.
[tex]\rm APR = 2400 \times money\ factor\\\\Money \ factor = \dfrac{ARP}{2400}[/tex]
Therefore,
The money factor will be used to calculate Bob’s payment is;
[tex]\rm APR = 2400 \times money\ factor\\\\Money \ factor = \dfrac{ARP}{2400}\\\\Money \ factor = \dfrac{0.08}{2400}\\\\Money \ factor =0.0033[/tex]
Hence, the money factor will be used to calculate Bob’s payment is 0.0033.

On a certain hot summer's day, 392 people used the public swimming pool. The daily prices are $1.25 for children and 2.50 for adults. The receipts for admission totaled $758.75 How many children and how many adults swam at the public pool that day?
Answer:
children = 177, adults =215
Step-by-step explanation:
im too lazy to write but solve this with a systeme
x(children),y(adults)
x+y=392
x=392-y
2.5y+1.25x=758.75
2.5y+1.25(392-y)=758.75
2.5y+490-1.25y=758.75
490+1.25y=758.75
1.25y=758.75-490
1.25y=268.75
y=268.75/1.25
y=215
x=392-215=177(number of kids)

Answer:
d = √149 = 12.2
Step-by-step explanation:
Distance between 2 coordinates: d = √[(x2 − x1)^2 + (y2 - y1)^2]
d = √[(0 - 7)^2 + (2 - -8)^2]
d = √[(-7)^2 + (10)^2]

Solve 5(n-2)=-30 check your solution
Answer:
n>=-4
Step-by-step explanation:
(0 - 5 • (n - 2)) - 30 ≤ 0
-5n - 20 = -5 • (n + 4)
-5 • (n + 4) ≤ 0
Divide both sides by -5
Subtract 4 from both sides which is n ≥ -4
Answer:
n = -4Step-by-step Solution:
5(n - 2) = -30=> 5n - 10 = -30=> 5n = -30 + 10=> 5n = -20=> n = -4Check:
5(n - 2) = -30 => 5(-4 - 2) = -30=> 5(-6) = -30=> -30 = -30Hence, this is correct.

Answer:
x = 10
y = 25
Step-by-step explanation:
if you add the equations as they are then the 'y-term' is eliminated:
60x = 600
x = 10
substitute x=10 to find value of 'y':
40(10) + 4y = 500
400 + 4y = 500
4y = 100
y = 25
Check:
20(10) - 4(25) should equal 100
200 - 100 = 100
100 = 100
