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.

Calculate the first and second velocities of the car with three washers attached to the pulley, using the formulas v1 = 0. 25 m / t1, and v2 = 0. 25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0. 25 and the 0. 50 meter marks. Record these velocities, to two decimal places, in Table E. What is the first velocity of the car with three washers at the 0. 25 meter mark? m/s What is the second velocity of the car with three washers at the 0. 50 meter mark? m/s.
The first and second velocities of the car are 0.25/t1 and 0.50/t2 respectively.
Given data:
The value of the first distance is, d1 = 0.25 m.
The value of the second distance is, d2 = 0.50 m.
What is velocity?The ratio of distance covered by an object in a specific direction and the time taken to cover the distance is known as the velocity of the object. Mathematically, the expression for the velocity is,
v = d/t
Here, d is the distance covered.
And t is the average time taken to cover the distance.
Then the first velocity of the car at 0.25 m is,
v1 = d1/t1
v1 = 0.25 / t1
Here, t1 is the average time for the first distance.
And the second velocity of the car with four washers at the 0. 50 m mark is,
v2 = d2/t2
v2 = 0.50 /t2
here, t2 is the average time for the second distance.
Thus, we can conclude that the first and second velocities of the car are 0.25/t1 and 0.50/t2 respectively.

The triangles are similar, what is the value of x?
Answer:
x = 16
Step-by-step explanation:
I'm not too sure but what I remember is the small triangle is upscale times 4. so 5x4= 20 3x4=12 and that would mean 4x4 = 16. so x will equal 16.

Create two Polynomials that when you subtract them you are left with 3x^2-4x+2
Answer:
[tex]=5x^{2} +2x-4-(2x^{2} +6x-6)\\=5x^{2} +2x-4-2x^{2} -6x+6\\=5x^{2} -2x^{2} +2x-6x-4+6\\=3x^{2} -4x+2[/tex]

Hence,5x²+2x-4 and 2x²+6x-6 are the two polynomials.
To create them:
Let,5x²+2x-4 be the first polynomial and x be the another
Now, we have,
→5x²+2x-4-x=3x²-4x+2
→5x²+2x-4-(3x²-4x+2)=x

is anyone solving this?
pls help
Answer:
Step-by-step explanation:
12ab - 10b² - 18a² + 9ab + 12b² + 14a²
= 12ab + 9ab - 10b² + 12b² -18a² + 14a² {Combine like terms}
= (12 + 9)ab + (-10 + 12)b² + (-18 + 14)a²
= 21ab + 2b² - 4a²
ab + 2b² + 3b² - a² = ab + (2+3)b² - a²
= ab + 5b² - a²
Now find the difference
ab + 5b² - a² - [ 21ab + 2b² - 4a²]
= ab + 5b² -a² - 21ab - 2b² + 4a²
= ab - 21ab + 5b² - 2b² - a² + 4a²
= -20ab + 3b² + 3a²

Answer: A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.

The speed of sound varies depending on many factors including temperature, pressure, and humidity, but it is
typically found to be approximately 550 m/s. What is the frequency of a sound wave with a wavelength of 0.2 m?
Answer: Hope this helps
Step-by-step explanation:The equation for finding the frequency of a sound wave given speed and wavelength is:
Speed = Wavelength * Frequency
Therefore, by algebra;
Frequency = Speed / Wavelenght
The given values are:
speed = 330 m/s
wavelength = 0.1 m
Therefore to solve for frequency:
Frequency = (330 m/s) / 0.1 m = 3.3 kHz
Therefore, the frequency of a sound wave at wavelength equals 0.1 m 3.3 kHz.

When “it says make a display (dot plot, box plot, or histogram) of the data set and explain why you chose the type of display to represent this data set.”
What would I need to do on that? It would be great if I could get some step by step instructions on how I should work that out?
(Only needing instructions for question 6, don’t mind the other stuff)
Step-by-step explanation: What they mean is if you were to say put all that data onto a graph, any kind of graph. What graph would you chose, and why? How you would work through this kind of problem, or at least how I would approach it weight out the pros and cons of each graph, or put some data on different graphs and see what works best. On the contrary if you have a rough idea of how each graph would look like you would just chose the one you think conveys the information best. I think they're is a best answer, but no wrong answer, you can make an argument for most graphs if you try, so just chose the one you think is best, and write your reasoning.

A cube has a volume of 64. What is the length of one side of the cube?
Answer:
4
Step-by-step explanation:
The volume of a cube can be represented as s^3 = v, where s = side and v = volume. In this case, we're given the volume as 64, so s^3 = 64. To solve this problem, we first have to know what a cube root is.
What's a cube root?
The cube root of a number is the number you multiply by itself 3 times to get another number.One common cube is 27, and the cube root of it is 3 because 3 x 3 x 3 = 27.Given the information above, let's go in order with the list of cube roots to see which one has a cube of 64.
1: 1 x 1 x 1 = 1. 2: 2 x 2 x 2 = 8. 3: 3 x 3 x 3 = 27.4: 4 x 4 x 4 = 64. (This is the cube root!)We found the cube root of 64, or the side of the cube with a volume of 64. The side of the cube, therefore, is 4.

Answer:
The house's value increased by $24,120. The current value of the house is $292,120
Step-by-step explanation:
First off, we need to multiply the percentage (9%) by the previous value of $268,000. In order to do that, we need to turn the percentage into a decimal. So, 9% → .09
268,000 x .09 = 24,120
Now you can add this number to the previous house value to get your current house value. (Your house increase in value by 24,120)
24,120 + 268,000 = 292,120

degree of angles are

The value of variable, x as required to be determined from the attached image is; 28.33°.
What is the value of variable, x as represented?It follows from the image attached to the task content that the given shape is a 7-sides polygon.
Also, it is noteworthy to know that the sum of interior angles in a polygon is given by the formula; ( n - 2 ) × 180.
where, n = no. of sides of the polygon.
On this note, we have that; for a 7-sided polygon; the sum of interior angles is;
= ( 7 - 2 ) × 180
= 5 × 180
= 900.
Therefore, all interior angles can be summed up so that we have;
x + 139 + 143 + 2x + 152 + 140 + 125 + 116 = 900
3x + 815 = 900
3x = 900 - 815
3x = 85
x = 85 / 3
x = 28.33°.
Ultimately, the value of x as required to be determined is; 28.33°.
