4.) Fill in the table to show a proportional relationship and then identify the

Lady bird [3.3K]

Answer/Step-by-step explanation:

✔️Number of Yoga classes = x

Cost ($) = y

Constant of proportionality (k) = y/x

Using the pair form the table of values given, (4, 60), find the constant of proportionality:

✅k = 60/4 = 15

Equation that represents the relationship between x and y is:

y = 15x

✔️Let's complete the table.

✅When number of yoga classes (x) = 2:

Substitute x = 2 into y = 15x

Thus,

y = 15*2 = 30

That is, 2 Yoga classes will cost $30

✅When number of yoga classes (x) = 6:

Substitute x = 6 into y = 15x

Thus,

y = 15*6 = 90

That is, 6 Yoga classes will cost $90

✅When number of yoga classes (x) = 8:

Substitute x = 8 into y = 15x

Thus,

y = 15*8 = 30

That is, 8 Yoga classes will cost $120

Use the diagram and equations. below to match the following angles with their correct measures

Lorico [155]

So you would set angle y plus angle z equal to 90 degrees.
2b + 6 +3b - 1 = 90
5b + 5 = 90
5b = 85
b = 17
so for y 3(17)-1 = 50 degrees
so for z 2(17) + 6 = 40 degrees
angle y and w form a straight line equal to 180 degreew so w = 180 - 50 = 130 degrees which leaves x being 140 degrees

A room is 20 feet long, 12 feet wide, and 10 feet high. What is the maximum distance from one corner to another

exis [7]

Answer:

25.38

Step-by-step explanation:

Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.

20^2+12^2=c^2

400+144=544=c^2

c= $\sqrt{544}$

then find corner of floor to opposite roof corner.

100+544=644=c^2

c= $\sqrt{644}$

so its about 25.38 feet
