Answer:

9, 11 , 13

Step-by-step explanation:

Find the average of 7 and 15, that is

[tex]\frac{7+15}{2}[/tex] = [tex]\frac{22}{2}[/tex] = 11

We now have 7, 11, 15

Now find the average of 7 and 11, 11 and 15

[tex]\frac{7+11}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9

[tex]\frac{11+15}{2}[/tex] = [tex]\frac{26}{2}[/tex] = 13

Thus the 3 arithmetic means between 7 and 15 are

9, 11, 13

Answer:

[tex]\huge\boxed{m\angle 1 = 131 \textdegree}[/tex]

[tex]\huge\boxed{m\angle 2 = 49 \textdegree}[/tex]

[tex]\huge\boxed{m\angle 3 = 112 \textdegree}[/tex]

Step-by-step explanation:

We can use basic angle relationships to find the measure of angles 1, 2, and 3 here.

First off, we know that the 49° angle and m∠1 are supplementary. This means that their angle measures will add up to 180°.

Since we know one, we can find the other easily.

[tex]x + 49 = 180\\\\x = 180-49\\\\x = 131[/tex]

So m∠1 = 131°.

We also know that m∠2 is opposite to the 49° angle. This means that m∠2 is also 49°.

Now, we know that m∠3 is also opposite to the 112° angle. Therefore, their angle measures are the same, and m∠3 is also 112°.

Hope this helped!

Answer:

-3a^2+11a

Step-by-step explanation:

Answer:

4a-a×3a+7a

or, 3a×3a+ 7a

or,9a+7a

or,16a

:. a =16

10 cubic centimeters of a 60% alcohol solution, would mean 10 x 60% = 6 cc is alcohol the other 4 cc is water.

To make a 90% solution, the water would be 10% of the solution.

If 4 cc is 10%, the total is 40 cc.

40 - 10 = 30 cc

30 cubic centimeters needs to be added.

Answer:

55% are women

Step-by-step explanation:

27÷60= 0.45

0.45x100=45

100-45=55

45% men

55% women

There are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

A manufacturing plant has 60 supervisors. If 27 of the supervisors are men.

The number of women = 60 – 27 = 33

The percent of women = (33/60)×100

= 0.55×100

= 55%

Thus, there are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.

B) There are 3 terms in the simplified product.

E) The final simplified product is –3y2 + 37y – 84.

The true statements are:

B. The simplified product has three terms

E. –3y2 + 37y – 84 is the final simplified product.

Given the polynomial expression, –3(y – 5)² – 9 + 7y, to simplify, do the following:

–3(y – 5)(y – 5) – 9 + 7y

-3y² + 30y - 75 - 9 + 7y

Combine like terms

-3y² + 37y - 84 (three terms)

Therefore, the statements that are true are:

B. The simplified product has three terms

E. –3y2 + 37y – 84 is the final simplified product

Answer:

An inequality 'c ≥ 5' represents this situation.

Step-by-step explanation:

We know that the inequality symbol '≥' represents 'at least'.

For example, 'x≥y' means 'x' is greater than or equal to b. It means 'x' is at least equal to 'y'.

Let 'c' represent the number of minivans sold each week.

As a car dealer ship sells at least 5 minivans. It means the dealer can also sell more than 5.

i.e. c ≥ 5

Therefore, an inequality 'c ≥ 5' represents this situation.

Answer:

the ratio is 1:50

this means that 1 meter in the drawing is equal to 50 meters in real life, but that is a complicated way of stating something simple since drawings are not generally measured in meters.

the door is 0.8 meters wide or 80 centimeters wide

in our drawing, the door should be 80 / 50 = 1.6 centimeters wide

the whole purpose of a scale is to allow us to work with smaller units, that is why we have to work with them. It is true that 0.016 meters = 1.6 centimeters, but as I said before, writing the answer in meters just complicates things and makes them harder to understand. You could also say it is 0.000016 kilometers wide and it would be right, but too confusing.

Answer:

B. $0.88

Step-by-step explanation:

x = number of bananas

y = cost of bananas in dollars

Given that 4 bananas cost $3.52, the constant of proportionality that relates cost of bananas, y, to the number of pounds of bananas, x = y/x

y = 3.52

x = 4

Therefore:

Constant of proportionality = [tex] \frac{3.52}{4} = 0.88 [/tex].

Answer:

They need to sell 3 tees, and incurred $60.  

Step-by-step explanation:

What is the revenue equation? R = 20x, where x is the # of tees sold.

What is the cost equation? C = 5x + 45, where x is the # of tees sold.

Set those two equations equal, we get:

20x = 5x + 45, 15x = 45, x = 3.

3*5 + 45 = 60.

Answer:

A

Step-by-step explanation:

If you follow the dotted lines and bring all the lines together,

angle8 = angle4 (corresponding angles)

angle8 = angle5 (vertically opposite angles)

angle5 = angle1 (corresponding angles)

Therefore, angle8 is basically the same as angles 1 and 4

Thus,

127+127=254

Answer:

The ordered pair is (4,6)

Step-by-step explanation:

Ordered Pairs

It's given the equation

y = x + 2

Since there are no restrictions for the values of x and y, it has infinitely many solutions, i.e. any ordered pair of values (x,y) that make true the equation is a solution.

We can pick any value for x and then calculate the corresponding value for y as follows:

For x = 4,

y = 4 + 2 = 6

The ordered pair is (4,6)

The answer is C!
