Xavier needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 4. 5 hours and charged him $155 for parts. The total was $357. 50. Write and solve an equation which can be used to determine xx, the cost of the labor per hour. ?

Answers

Answer 1

Answer:

The cost is $45 per hour.

Step-by-step explanation:

(h = hours)

1. The equation is 4.5h + 155 = 357.5.

2. Subtract 155 from both sides of the equal sign. The equation is 4.5h = 202.5.

3. Divide both sides by 4.5. The answer is h = 45.

Did you figure out the answer
Answer : y = -3x + 2

From the table the x and y values can be grouped as ordered pairs
i.e (x,y)
(1,-1) ,(2,-4) , (3,-7) as (x1,y1) , (x2,y2) and (x3,y3) respectively

[(y-y1)/(x-x1)] = [(y3-y2)/(x3-x2)]

[(y-(-1))/(x-(1))] = [((-7)-(-4))/((3)-(2))]

(y+1)/(x-1) = (-7+4)/(3-2)

(y+1)/(x-1) = -3/1

Cross multiply

(y+1)=-3(x-1)

y+1 = -3x + 3

y = -3x + 3 -1

y =-3x + 2

The mode of a data set is the most frequently occurring value (the value that occurs the most)

We see each number once except for 26, which is there twice. There are no other numbers that are there twice other than 26, so 26 is the mode of the data set.

Two different cars each depreciate to 60% of their respective original values. The first car depreciates at an annual rate of 10%. The second car depreciates at an annual rate of 15%. What is the approximate difference in the ages of the two cars? 1. 7 years 2. 0 years 3. 1 years 5. 0 years.

Answers

The approximate difference in the ages of the two cars, which  depreciate to 60% of their respective original values, is 1.7 years.

What is depreciation?

Depreciation is to decrease in the value of a product in a period of time. This can be given as,

[tex]FV=P\left(1-\dfrac{r}{100}\right)^n[/tex]

Here, (P) is the price of the product, (r) is the rate of annual depreciation and (n) is the number of years.

Two different cars each depreciate to 60% of their respective original values. The first car depreciates at an annual rate of 10%.

Suppose the original price of the first car is x dollars. Thus, the depreciation price of the car is 0.6x. Let the number of year is [tex]n_1[/tex]. Thus, by the above formula for the first car,

[tex]0.6x=x\left(1-\dfrac{10}{100}\right)^{n_1}\\0.6=(1-0.1)^{n_1}\\0.6=(0.9)^{n_1}[/tex]

Take log both the sides as,

[tex]\log 0.6=\log (0.9)^{n_1}\\\log 0.6={n_1}\log (0.9)\\n_1=\dfrac{\log 0.6}{\log 0.9}\\n_1\approx4.85[/tex]

Now, the second car depreciates at an annual rate of 15%. Suppose the original price of the second car is y dollars.

Thus, the depreciation price of the car is 0.6y. Let the number of year is [tex]n_2[/tex]. Thus, by the above formula for the second car,

[tex]0.6y=y\left(1-\dfrac{15}{100}\right)^{n_2}\\0.6=(1-0.15)^{n_2}\\0.6=(0.85)^{n_2}[/tex]

Take log both the sides as,

[tex]\log 0.6=\log (0.85)^{n_2}\\\log 0.6={n_2}\log (0.85)\\n_2=\dfrac{\log 0.6}{\log 0.85}\\n_2\approx3.14[/tex]

The difference in the ages of the two cars is,

[tex]d=4.85-3.14\\d=1.71\rm years[/tex]

Thus, the approximate difference in the ages of the two cars, which  depreciate to 60% of their respective original values, is 1.7 years.

A polygon simply means a plane figure which is described by a finite number of straight line segments that are connected in order to form a closed polygonal chain.

In this case, the length of a line segment can be measured by simply measuring the distance between the two endpoints.

Answers

Answer: Supplementary angles

Step-by-step explanation:

Bye have a nice day.

Answer:

does this help answer your question? Answer: They are supplementary angles, because angle 1 + angle 2 = 180° , i.e. they form a line.

Step-by-step explanation:

I would suggest that you memorize these -

    1. Complementary angles always =90°

For example, 30 degrees and 60 degrees are complementary angles.

    2. Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way. (share a side)

    3. Supplementary angles are those that in sum give 180°.

    4. Vertical angels ---- each of the pairs of opposite angles made by two intersecting lines.

So, what have you learned? You learned that complementary angles are two angles that add up to 90 degrees, supplementary angles are two angles that add up to 180 degrees, vertical angles are opposite angles at an intersection of two straight lines, and adjacent angles are two angles that are next to each other.

Identify the key features of the parabola that is formed by the equation

the y-intercept

the vertex

Is the vertex a maximum/minimum?


Round your answers to the nearest whole number.

Answers

Answer:

y-intercept: 58vertex: (2, 78) -- a maximum

Step-by-step explanation:

The negative leading coefficient tells you this parabola opens downward, so the vertex will be a maximum. The constant is the y-intercept, which is 58.

__

The vertex is nicely found using a graphing calculator, but can also be found algebraically. The x-value is ...

  x = -b/(2a) = -19.8/(2·(-4.9)) = 19.8/9.8 = 99/49 ≈ 2.02041

The value of f(99/49) is ...

  f(99/49) = (-4.9(99/49) +19.8)(99/49) +58 = (9.9)(99/49) +58 ≈ 78.002

The location of the vertex is approximately ...

  (x, y) ≈ (2.0204, 78.002) ≈ (2, 78)
