Solve the proportions 21 over 20 =m over 100

Answer:

8.5 hours

Step-by-step explanation:

30 mins per page ( 15 )

so, 30 × 15 = 450

each hour is 60 minutes so 450 ÷ 60 = 7.5

then add the 1 hour that she already took to write the outline, so 8.5 hrs

Answer: y=mx+b = y=30(15)+1

Explanation: the slope is 30 because that's how many minutes it will take her to write each page and x will be the amount of pages she is doing as b is the 1 hour she spent doing her outline. (Hope this helped if I'm incorrect I'm so sorry, I'm tired)

Answer:

mhm thats great points man pointsssss idc

Answer:

the answer is B. Yes, x and y have a proportional relationship

Step-by-step explanation:

2 ÷ 5 = 0.4

3 ÷ 7.5 = 0.4

5 ÷ 12.5 = 0.4

8 ÷ 18 = 0.4

Step-by-step explanation:

One's digit of N can be 2 or 7.

Answer:

Step-by-step explanation:

If the number ends in 0 or 5 those are the only two results that 5 will divide into a number evenly.

For example 105/5 = 21

And example 1020/5 = 204

So if you want a  remainder of 2, there are 2 ways to get it.

1) If the number ends in a two, you will get a remainder of 2. That's because 0 + 2 will give 2.

For example 252 / 5 = 50 with a remainder of 2

2) The other way is if the end number is 7.

3347 / 5 = 669 with a remainder of 2.

The reason this works is if you subtract 2 from the number given then the units digit will be either 0 or 5. Those two endings result in even division.

Answer:

A, (1, 3+1/2)

Step-by-step explanation:

Midpoint formula for reference: m= {(x1 + x2)/2, (y1 + y2)/2}

Plugging in the points we get: m= {(8 - 6)/2, (5 + 2)/2}

Now we simplify using PEMDAS. First step is parentheses.

m= {2/2, 7/2}

Simplifying again (and making 7/2 a mixed number), it becomes

m= {1, 3+1/2}

Hope this helps!

Answer:

A

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

Let x and y represent the number of adult and student tickets sold, respectively. The various limits and goals can be expressed as ...

  x + y ≤ 130 . . . . . . limit on available seats

  9.50x + 5.00x ≥ 950 . . . . . goal for revenue achieved

The plots of these inequalities are shown in the attachment, along with one possible solution: (x, y) = (80, 45).

Sale of 80 adult tickets and 45 student tickets will achieve the desired goal.

Step-by-step explanation:

Answer: 1

because a variable by itself is always 1

Step-by-step explanation:

Let ABC be an isosceles triangle with sides AC and BC of equal length.                

We need to prove that the medians AD and BE are of equal length.

Consider the triangles ADC and BEC.

They have two congruent sides that include congruent angles.

Indeed, AC = BC by the condition, because the triangle ABC is isosceles.

Since the lateral sides AC and BC are of equal length, their halves EC

and DC are of equal length too: EC = DC.

Finally, the angle ECD is the common angle.

Thus, the triangles ADC and BEC are congruent, in accordance to the

postulate P1 (SAS) (see the lesson Congruence tests for triangles of the

topic Triangles in the section Geometry in this site).

Hence, the medians AD and BE are of equal length as the corresponding sides

of these triangles.

The proof is completed.

Answer:

362

Step-by-step explanation:

15xy=5430...therefore 5430divided by 15 is 362...so 362x15 their product is 5430

Answer:

12

Step-by-step explanation:

First find the constant of proportionality, so 18/12=1.5  Then, multiply that constant by 8 to find what x equals  8*1.5=12.

Hopefully this is right!  :)

As per the scatter plot the association between the population of various states in the US and the number of cell phone users is strong, weak, and moderate. Thus option One is correct.

A scatter plot is a scatter graph that shows and compares the individual values and correlates them with the variables.

Here the case of cell phones in the US is shown as strong as the line is positively correlated and more than half of the people use cell phones thus it's moderate.

Find more information about the scatter plot.

Answer:

strong

positive

the same

Step-by-step explanation: read the question instead of just copying and pasting into another tab its really simple. Strong because all the dots are really close to each other, positive becasue the dots are leading up, and the same because its literally the same if you put them 2 dots on

EDMENTUM this will correct

Answer:

113 adult tickets

Step-by-step explanation:

Brainliest please

Answer:

108 adult tickets sold

Step-by-step explanation:

To do this equation, we can set x equal to the number of adult tickets sold, and then set up the following equation:

x + 3 x = 432

Since there are three times as many student tickets as adult tickets and the total is 432, you can just use all this information together to make an equation. From there, you can combine like terms to create this equation:

4 x = 432

After this, just divide both sides by 4 to reach the answer of:

x = 108
