6x3+8x2-2x+4=30-2x
10x3+x2+11x+9=21+13x
Answer:
You need to use trigonometry to find out the angle.
We use the cosine rule here.
Assuming our angle to be 'x',
cos x = adjacent / hypotenuse
here, adjacent = 35, hypotenuse = 38
cos x = 35/ 38
x = cos^-1 35/38
x = 22.9°
I can probably answer if you give me the ratio
The average of 3 numbers is their total divided by 3.
(150 +205 +178)/3 ≈ 178.67
Rounded to the nearest dollar, the average charge for the period is $178 per month.
18/20=9/10 9*10=90%
use the fraction or decimal then multiply by 100 or ten depending
