The cost of a service call to fix a washing machine can be expressed by the linear function y = 45 x + 35, where y represents the total cost and x represents the number of hours it takes to fix the machine. What does the y-intercept represent?

Answer:

Step-by-step explanation:

Use PEMDAS rule

First do the operations inside the parenthesis

[(8 -2 ) * (3 + 2) - 1] * 3 = [ 6 * 5 - 1]*3

Now multiplication

                                   = [ 30 - 1] *3

                                  = 29 *3

                                 = 87

Answer:

1/7.

Step-by-step explanation:

You can find which is closest to zero by using the LCD. However, the question itself just shows us that 1/7 is the right choice. If you want the work, just comment.

Answer:

A) 25% and C) 15

Step-by-step explanation:

both lines and boxes represent 25% and the first line ends at exactly 20 making everything under 20 25%

If you add the pink and purple lines that are both 12 emails and over then you get 15 people

hope that made somewhat sense XD

Step-by-step explanation:

it is simply 30

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.

Step-by-step explanation:

The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.

For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.

I've enclosed an attachment for that.

Hope this helps!

Answer:

$9.65

Step-by-step explanation:

1.25 * 2 = 2.5 + 4.15 + 3.5 - 0.5 = $9.65

Answer: y = 6

Step-by-step explanation:

1. Subtract 7 from both sides to isolate -2y.

-2y = -12

2. Divide both sides by -2 to isolate the y.

y = 6

Answer:

blank 1- 7

blank 2- 5

Step-by-step explanation:

9 times 7 is 63

7 times 5 is 35

Step-by-step explanation:

The difference beteen 9.2 ounces and 8.1 ounces is  1.1 ounces

   and the difference in price is   .49

       so 1.1 ounces cost .49

           $ .49 / 1.1 oz = $  .445  per ounce

Then Reid's bowl should cost   7.8 oz  * $ .445 / oz = $3.47

Answer:

If Rick is 30,Mark is 28,Jeff is 24

If Jeff is 25,Mark is 29,Rick is 31

If the total is 112 than mark is 38

(Rick)40+38(Mark)+34(Jeff) =112

B. Most Of The The Data Is From 1 To 6

Step-by-step explanation:

Step-by-step explanation:

The lateral surface area is the area of the sides, not including the top and bottom.

Assuming the 3×6 rectangles are the top and bottom, the lateral surface area is:

LA = 2×3 + 2×3 + 2×6 + 2×6

LA = 6 + 6 + 12 + 12

LA = 36

The total surface area is the lateral surface area plus the area of the top and bottom.

SA = 36 + 3×6 + 3×6

SA = 36 + 18 + 18

SA = 72

Answer: 73

Step-by-step explanation:

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)
