When xb= 12, y = 8. Find x when y = 12

Answers

Answer 1

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:

-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

0.45m - 9 = 0.9m
-9 = 0.45m

If the next part asks you to solve for m, you’ll divide both sides of the equation by 0.45, and find m = -20

Who can help me out with this question? The tutors haven’t been working for 3 days

Answers

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 = 20

We 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.

The volume of a compound shape . 10 cm & 12 cm .

Answers

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
