Consider the two triangles. Triangles A B C and H G I are shown. Angles A C B and H I G are right angles. The length of side A C

is 15 and the length of side C B is 20. The length of side H I is 12 and the length of I G is 9. To prove that the triangles are similar by the SAS similarity theorem, it needs to be shown that

Answer:

I think it's

D. AC/GI = BC/HI

Step-by-step explanation:

Angles that are congruent don't necessarily mean they're similar. But this is what I saw that is associated with similarity with triangles.

AC and GI are corresponding sides and BC and HI are corresponding sides as well so, yeah. D.

I think.

I guess.

I don't know.

I didn't pay attention, tbh. LOL

In supply (and demand) problems, y is the number of items the supplier will produce (or the public will buy) if the price of the
SSSSS [86.1K]

Answer:

A) (17 ; 550)

B) $17/item

C) 550

Step-by-step explanation:

First we must calculate the intersection point of the two lines. Since in that point <em>y</em> has the same value in both equations, we can obtain <em>x </em>by equalling the two equations and then using that value for obtaining <em>y</em>:

5x+465=-6x+652\\5x+6x=652-465\\11x=187\\x=\frac{187}{11}\\x=17

So the value of <em>x</em> in the intersection point is 17. We now use this value with either one of the equations to obtain <em>y</em><em>. </em>Let's use the supply equation:

y=5*17+465\\y=550

So the intersection point is (17 ; 550)

Supply and demand are in equilibrium when the amount of items on supply are the same as the ones on demand. That is the point were the two lines intersect, which means the selling price is the <em>x</em> coordinate and the amount of items is the <em>y</em> coordinate, so that is a selling price of <em>$17/item</em> with a number of items of <em>550</em>.

A girl is 18 years old and her brother is a third of her age. When the girl is 36 what would be the age of the brother?
ale4655 [162]
First we need to calculate how many years her brother has when she is 18. As text says he is:
18/3 = 6 years old

Now when she gains another 18 years (36-18=18) he will also gain those 18 years

When she is 36 he will have 6+18=24 years old

Answer is 24.

What is the variable of p and k explain please
scoundrel [369]
For the P=-4
what you do is subtracting 6 to the 38 you will have -8p=32 then you will divide-8 to both sides and your answer will be p=-4
check 6-8(-4)=38
6+32=38
38=38


i got K=5.6
what you do is add 13 to the 15 and you will have 28=5k then you will divide 5 to both sides and you will have k=5.6
check 15=5(5.6)-13
15=28-13
15=15
