1/1There is a proportional relationship between the volume of a sample of helium in liters and the mass of that sample in grams. If the mass of a sample is 5 grams, its volume is 28 liters. (5, 28) is shown on the graph below

What is the constant of proportionality in this relationship?

In this situation, what is the meaning of the number you found in question 1?(explain in the short answer)
Add at least three more points to the graph above, and label with their coordinates.(Show your work)

Write an equation that shows the relationship between the mass of a sample of helium and its volume. Use m for mass and v for volume.(Please answer in v = form)

Answers

Answer 1

Answer:

Answer:

$v = (28m)/(5)$

Step-by-step explanation:

The meaning behind the constant of k = 28/5 is that it says that 1 gram of helium takes up 28/5 = 5.6 liters of space, and each time you increase the mass by 1 gram, the space increases by 5.6 also

3 more points:

- V1 = 28/5 * 10 = 56 liters

- v2 = 28/5 * 15 = 84

- V3 = 28/5 * 20 = 112

A mother decides to teach her son about a letter each day of the week. She will choose a letter from the name of the day. For example, on Saturday she might teach about the letter S or the letter U, but not the letter M. What letters are possible to teach using this method? (There are 15.) List all the letters in alphabetical order, with no spaces

Answers

Answer:

A, D, E, F, H, I, M, N, O, R, S, T, U, W, Y

Explanation:

Order the letters of each day, omitting the repetitions:

MONDAY:

A, D, M, N, O, Y

TUESDAY:

A, D, E, S, T, U, Y

WEDNESDAY:

A, D, E, N, S, W, Y

THURSDAY:

A, D, H, R, S, T, U, Y

FRIDAY:

A, D, F, I, R, Y

SATURDAY:

A, D, R, S, T, U, Y

SUNDAY:

A, D, N, S, U, Y

Put the letters together:

A, D, M, N, O, Y, A, D, E, S, T, U, Y, A, D, E, N, S, W, Y, A, D, H, R, S, T, U, Y, A, D, F, I, R, Y, A, D, R, S, T, U, Y, A, D, N, S, U, Y

Delete the repetitions:

A, D, M, N, O, Y, E, S, T, U, W, H, R, F, I.

Reorder:

A, D, E, F, H, I, M, N, O, R, S, T, U, W, Y ← answer

Please show me how to do it.

$(8^(2n - 3) * 2^(n - 3))/(4 * 2^(-n + 2)) = (2^(3(2n - 3)) * 2^(n - 3))/(4 * 2^(-n + 2)) = (2^(3(2n) - 3(3)) * 2^(n - 3))/(4 * 2^(-n + 2)) = (2^(6n - 9) * 2^(n - 3))/(2^(2) * 2^(-n + 2)) = (2^((6n - 9) + (n + 3)))/(2^(2 - n + 2)) = (2^((6n + n) + (-9 + 3)))/(2^(-n + 2 + 2)) = (2^(7x + (-12)))/(2^(-n + 4)) = (2^(7x - 12))/(2^(-n + 4)) = 2^(8n - 16)$

Which is greater, 0.5 or 2/3??

Answers

Find the average=.gr2ate2+0.5+ 23 3
Find the least common multiple (LCM) of the denominators in order to find the least common denominator (LCD).
which equals 3
Find the mean (arithmetic)-.gr^2ate^2+0.5+ 23 3
The LCM (least common multiple) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.=2grat

In other words:
0.5, 3/5, 0.65, 2/3
Hope this helps
So therefore, 2/3 is greater

0.5, 2/3 = 0.6So 2/3 is greater.Hope it helps and pls mark as the best answer. :-)

How do i solve exterior angles on triangles (picture)

Answers

remember
the exterior angle=sum of the other 2 interior anlges

therfor
(one that is less pointy triangle)
2x+3x=135
5x=135
x=27
2*27=54
3*27=81
the interior angles are 54 and 81 and x=27

other pointier one with 3x-1 on it
12+3x-1=167
11+3x=167
minus 11
3x=156
divide 3
x=52
sub
3*52=156
156-1=155
missin angle is 155, x=52
attachment below (in degrees)

you recieve exterior angles by adding the degrees
