Answer:
no, it is not a proportional relationship.
Step-by-step explanation:
if you divide 315 by 175 you get 1.8
if you multiply 315 by 1.8, you don’t get 420. therefore this is not a proportionally relationship.
hope this helps!
Hi
35/100= 140/ X
X = 100*140 /35
X= 14000/35
X= 400
There are 400 computer in the compagny.
Answer:
θ =
°
Step-by-step explanation:
using the <u>SOHCAHTOA </u>method,
Here hypotenuse is 38, adjacent is 9
Using cosine formula:
![cos(x ) = \frac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=cos%28x%20%29%20%3D%20%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D)
![cos(x) = \frac{9}{38}](https://tex.z-dn.net/?f=cos%28x%29%20%3D%20%5Cfrac%7B9%7D%7B38%7D)
![x = cos^{-1} (\frac{9}{38} )](https://tex.z-dn.net/?f=x%20%3D%20cos%5E%7B-1%7D%20%28%5Cfrac%7B9%7D%7B38%7D%20%29)

Simplify your work by factoring before multiplying. We get:
4(3f-4) 5
---------- * -----------------
16 (3f-4)(3f+4)
Cancel the (3f-4) terms, obtaining:
20
------------------
16 (3f+4)
5
Reducing, we get ------------- and this is the desired result.
4(3f+4)
Plot the points ( -4,2.5), (-3,3), (-2,1.5), (-1,2), (0,1), (1,2), (2,3.5), (3,0.5), (4,2.5) then connect them with a line
