Answer:
If it is direct proportionality, then y = kx where k is a constant. Use the given information to find k:
8 = k(12) ⇒ k = 8/12 = 2/3
y = (2/3) x
For y = 12,
12 = (2/3) x ⇒ x = (3/2)*12 = 18
x = 18 when y = 12
I hope this helps a little bit.

Answer: Yes, the triangles are similar.
The triangles are similar due to the AAA similarity theorem.
=============================================================
Explanation:
Recall that for any triangle, the three inside angles must add to 180 degrees.
So for triangle ABC, this means that
A+B+C = 180
40+120+C = 180
160+C = 180
C = 180-160
C = 20
Similarly, we can find angle T by following these steps
R+S+T = 180
20+120+T = 180
140+T = 180
T = 180-140
T = 40
---------------------------
To summarize, we found angle C to be 20 degrees, and angle T is 40 degrees.
Now note these angle pairings in which they are the same measure
Angle A = Angle T = 40Angle B = Angle S = 120Angle C = Angle R = 20We have three pairs of corresponding angles that are congruent. By the AAA (angle angle angle) similarity theorem, this proves the triangles are similar. We can say triangle ABC is similar to triangle TSR. The order is important so we know how the angles pair up. For instance, A and T are the first letters of ABC and TSR respectively, helping us see that A and T pair up together.
Technically the minimum amount we need is only two pairs of corresponding angles, so some math textbooks use AA instead of AAA. It's the same idea though.
Unfortunately we don't have enough information to prove the triangles congruent or not. We would need to know some information about a pair of sides. Specifically, if we had one pair of congruent sides, then we could use either ASA or AAS.

At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 total calories and twice as many chicken wings as there are sliders. Write a system of equations that could be used to determine the number of chicken wings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.

Answer:
-9 = 0.45m
Step-by-step explanation:
[tex]0.45m - 9 = 0.9m[/tex]
^ Subtract 0.45m from BOTH sides. so [tex]0.9m - 0.45m[/tex]... etcWhy? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itselfThat will equal to:[tex]-9 = 0.45m[/tex] <-- ANSWER

Hank has 3 kilograms of candy. How many grams of candy does he have?
Answer:
3,000 grams of candy
Step-by-step explanation:
1 gram = 1,000
so, 3 (1,000)= 3,000
Answer:
3000 grams
Step-by-step explanation:
to convert from kilograms to grams we multiply by 1000
so 3*1000=3000g

The volume of a compound shape . 10 cm & 12 cm .
Answer:
total volume = (1150/3)pi cm^3
approximate total volume = 1204 cm^3
Step-by-step explanation:
The compound solid looks like it's made up of a cylinder with a base with 10 cm diameter and height of 12 cm and a half sphere with radius 10 cm.
volume of cylinder: (pi)(r^2)h
volume of sphere: (4/3)(pi)r^3
total volume = (pi)(r^2)h + (1/2)(4/3)(pi)r^3
We are given a diameter of 10 cm, so the radius is 5 cm since r = d/2.
total volume = (pi)[(5 cm)^2](12 cm) + (2/3)(pi)(5 cm)^3
total volume = 300pi cm^3 + (250/3)pi cm^3
exact total volume = (1150/3)pi cm^3
approximate total volume = 1204 cm^3
what is positive slope
Answer:
A positive slope means that two variables are positively related- that is when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.
