Answer

6/5 and 17/8

Step-by-step explanation:

1 1/5 = 6/5

1= 5/5 + 1/5 = 6/5

2 1/8 = 17/8

2 = 16/8 + 1/8 = 17/8

How many different ways are there to arrange the letters of the word PRISM?
Advocard [28]

Answer:

5! (5 factorial) or 120 ways

Step-by-step explanation:

You can arrange P different ways. R can be arranged only 4 different ways because Pwill be in one of the spots. Next, you can arrange "I" 3 different ways because P and R are already arranged in 2 spots, meaning you cant put "I" there. Next, S can be arranged in 2 different ways for the same reason. And lastly, M can only be arranged in 1 different way because the other spots are taken.

You can put it in any order. For example, M could be arranged 5 ways and P could be arranged in 1 way. You will still get 120 ways

Hopefully this helped. The explanation might be a bit confusing but I tried my best. I'm not good with explaining my solutions but I always try

(PRECALC) I need help on this one plz ❤️❤️❤️ help a girl out &amp; the favor will be returned

Answer:

The coordinates of the P' point are (-17.3,-10).

Step-by-step explanation:

We can use the components of the vector from 0 to P point. We know that the diameter is 40 meters, so the magnitude of the vector will be 20 m.

Now, the angle from the negative x-direction to the vector is 210°-180° = 30°.

The x-component of the vector will be:

V_{x}=-Vcos(30)

V_{x}=-20cos(30)=-17.32\: m

It is negative because the component is in the negative x-direction.

The y-component of the vector will be:

V_{y}=-Vsin(30)

V_{y}=-20sin(30)=-10\: m

It is negative too because the component is in the negative y-direction.

Therefore, the coordinates of the P' point are P'(-17.3,-10)

I hope it helps you!
