Triangle FGH has the following side lengths: FG = 5 ft, GH = 10 ft, HF = 12 ft Triangle PQR is similar to triangle FGH. The long

7nadin3 [17]

The first thing we must do for this case is find the scale factor.
We have then that for the larger side of both triangle, the scale factor is:
$k = \frac{RP}{HF}$
$k = \frac{7.2}{12}$
$k = 0.6$
To find the other two sides, we must apply the scale factor on each side of the triangle FGH.
We have then:

For PQ
$PQ = k * FG

PQ = 0.6 * 5

PQ = 3$

For QR
$QR = k * GH

QR = 0.6 * 10

QR = 6$

Answer:
You have that the lengths for the other two sides of triangle PQR are:
$PQ = 3

QR = 6$

10x - 12y = 22<br> 5x - 6y = 11 elimanation

lawyer [7]

Answer:

This is an identity or infinite solutions

Step-by-step explanation:

10x - 12y = 22

5x - 6y = 11

-2(5x - 6y = 11 )

-10x + 12y = -22

10x - 12y = 22

An amusement park ride has cars that move around a circular track at the rate of 16 revolutions in 20 seconds. To the nearest hu

astraxan [27]

Answer:

$5.03\frac{rad}{sec}$

Step-by-step explanation:

To find the angular velocity divide the revolutions by the time

so

$\frac{16}{20}=0.8\frac{rev}{sec}$

Remember that

$1\ rev=2\pi \ rad$

Convert rev/sec to rad/sec

$0.8\frac{rev}{sec}=0.8*(2\pi)=1.6 \pi\frac{rad}{sec}$

assume $\pi=3.1416$

$1.6(3.1416)=5.03\frac{rad}{sec}$
