2= 200
9 = 90
18 = 28

....
200 + 90 = 290 + 28 = 308
(28 + 90 = 118. 118 + 200 = 308) I'm thinking @[email protected]

Find the rectangular coordinates of the point ( -3, 1/2 π)

alexdok [17]

Answer:

$x = -3 cos (\frac{\pi}{2})= 0$

$y = -3 sin (\frac{\pi}{2})= -3$

And then the rectangular coordinates for this case are :

$(x = 0 , y = -3)$

Step-by-step explanation:

We have the following point given $P = (-3, \frac{\pi}{2})$ and we want to conver from polar to rectangular coordinates and we need to use the following formulas:

$x = r cos \theta$

$y = r sin \theta$

For this case we have that:

$r = -3$

And:

$\theta = \frac{\pi}{2}$

Replacing we got:

$x = -3 cos (\frac{\pi}{2})= 0$

$y = -3 sin (\frac{\pi}{2})= -3$

And then the rectangular coordinates for this case are :

$(x = 0 , y = -3)$

I need help with this pleaseee

Elodia [21]

Answer:

34, D

Step-by-step explanation:

Change 4 and 1/4 to an improper fraction

4 1/4 = 17/4

Now, you would divide 17/4 by 1/8...

17/4 divided by 1/8

Reciprocate the fraction 1/8 and change the division sign to multiplication to get...

17/4 multiplied by 8/1

= 136 / 4

Simplify

136 / 4

= 34

So, you can grow 34 plants.

Hope this helps!

The ratio of coloured papers to wight papers is 3:8.If there are 48 wight papers, how many coloured papers are there?

mestny [16]

Answer: The total number of colored papers is 18.

Step-by-step explanation:

Given: The ratio of coloured papers to wight papers is 3:8.

Let total number of colored papers = 3x

and total number of wight papers = 8x

Since, there are 48 wight papers , then

$8x=48$

$\Rightarrow\ x=6$

Now , number of colored papers = 3(6)=18

Hence, the total number of colored papers is 18.
