Answer:

the last on z-500

Step-by-step explanation:

since she is spending money she is losing money so it can't be 500z or z+500. also, she has $z and spent $500 of that $z, she is taking away from z so it would be z-500. I hope that makes sense if not let me know i'll try to explain it better :)

Prove Theorem 3: Corresponding angle bisectors of similar triangles are proportional and their ratio is equal to the ratio of si

RoseWind [281]

Answer:

The proof is given below.

Step-by-step explanation:

Given the two triangles which are similar we have to prove that the ratio of their angle bisectors and the side or we can say that the ratio of their altitude are proportional.

In ΔABP and ΔDEQ

∠1=∠2 (Given)

∠3=∠4 (each 90°)

By AA similarity rule ΔABP≅ΔDEQ

As if the two triangles are similar then their corresponding sides are proportional

⇒ $\frac{AB}{DE}=\frac{AP}{DQ}=\frac{BP}{EQ}$

Hence, Corresponding angle bisectors of similar triangles are proportional and their ratio is equal to the ratio of altitude.

A cyclist rides her bike at a rate of 12 meters per second. What is this rate in kilometers per hour? How many kilometers will t

IgorLugansk [536]

Answer:

Part 1) The rate is $43.2\frac{km}{h}$

Part 2) $129.6\ km$

Step-by-step explanation:

Part 1)

we know that

A cyclist rides her bike at a rate of 12 meters per second

Remember that

1 hour=3,600 seconds

1 kilometer=1,000 meters

therefore

$12\frac{m}{sec} =\frac{(12/1,000)}{(1/3,600)}=\frac{12*3,600}{1,000}=43.2\frac{km}{h}$

Part 2) How many kilometers will the cyclist travel in 3 hours?

using proportion

$\frac{43.2}{1}\frac{km}{h}=\frac{x}{3}\frac{km}{h}\\ \\x=43.2*3\\ \\x=129.6\ km$
