Henry is three more than twice Nicholas’ age. Marcus is 9 less than six times Nicholas’s age. If Henry and Marcus are twins, how old is Nicholas?

Answers

Answer:

Step-by-step explanation:

Henry is 3 more than twice Nicholas' age. You can write this as :

H = 3 + 2N

Marcus is 9 less than 6 times Nicholas' age:

M = 6N - 9

Since Henry and Marcus are twins, this means H = N.

3 + 2N = 6N - 9

Add 9 to both sides

12 + 2N = 6N

Subtract 2N from both sides

12 = 4N

Divide both sides by 4 to find N.

N = 12/4 = 3

A printing machine produces labels.Four percent of the labels produced are defective.Suppose 372 labels were defective.
how many labels are not defective?

Answers

Answer:

8928

Step-by-step explanation:

If 4% is 374, what is 1%? so 374/4

374 = 4%

93 = 1%

Now if 4% is defective, how many is not defective?

100% - 4% = 96%

If 1% is 93 then what is 100%?

8928 = 96%

There were 8,928 labels are not defective.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

We have been given that labels are created using a printing press. Four percent of the labels that are created are inaccurate.

Let the total number of labels would be x

As per the question, 372 labels were defective.

So 4% of x = 372

⇒ 4x/100 = 372

⇒ x = 37,200/4

⇒ x = 9,300

Since 4% is defective labels,

So labels are not defective: 100% - 4% = 96%

Now, we have to calculate the evaluation of 96% of 9,300.

⇒ (96/100)9,300

⇒ (0.96)9,300

⇒ 8,928

Therefore, there were 8,928 labels are not defective.

Answers

Answer:

The answer is below

Step-by-step explanation:

Let's work it out slowly

A)

$18.79 + $2.11 - $1.92 + $17.28

- 18.79 + 2.11 + 17.28 = 38.18

- 38.18 - 1.92 = 36.26

Ans = $36.26

B)

$7.45 + $24.45 + $74.17 + $76.52

- 7.45 + 24.45 = 31.9

- 74.17 + 76.52 = 150.69

- 150.69 + 31.9 = 182.59

Ans = $182.59

C) $98.45 - $10.63 + $2.82 - $20.26

- 98.45 - 10.63 - 20.26 = 67.56

- 67.56 + 2.82 = 70.38

Ans = $70.38

Hope you understand

The answer to A is $40.1
The answer to B is $-19.35
The answer to C is $70.38

Answers

Answer:

88 degrees

Step-by-step explanation:

First, notice that when you rotate a point 272 degrees clockwise, there will be 88 more degrees before it returns to its original point (since a 360 turn is equivalent to not moving, and 360-272=88).

Because of that, we can deduce that rotating a point 88 degrees counterclockwise will be equivalent to rotating it 272 degrees clockwise.

We can know that that's the smallest possible positive answer, because any angle smaller than 360 will be the smallest possible way to express it.

What do the differences between the points (as shown on the graph) represent?
Please answer

Answers

Answer:

Answer:

They represent the rise and run of the graph.

Step-by-step explanation:

Step-by-step explanation:

The difference between the x-axis of the points represents the "run" of the graph (or how much you should run along x-axis to get to the next point.)

The difference between the y-axis of of the points represents the "rise" of the graph (or how much you should rise up the y-xis to get to the next point).

The ratio of rise to run is the slope of the graph, which tells us  how many steps should we take on the y-axis for every step we move forward on the x-axis.

They represent the rise and run of the graph.  

The difference between the x-axis of the points represents the" run" of the graph( or how  important you should run along x-axis to get to the coming point.)  The difference between the y- axis of of the points represents the" rise" of the graph( or how  important you should rise up the y- x is to get to the coming point).  

The  rate of rise to run is the slope of the graph, which tells us how  numerous  way should we take on the y- axis for every step we move forward on the x-axis.
