Answer: <em>8 2/7 </em> i think :)
It’s increased to 9. A square is equal on all sides.
Answer:
c° = 28°
Step-by-step explanation:
hello :
you have the rectangle triangle : c°+62°+90° = 180°
c°+152°=180°
c° = 180°-152°
c° = 28°
Let,the time taken by larger pipe = x
By smaller pipe = x+5
It would be: 1/x + 1/(x+5) = 9/100
= x+5+x /(x)(x+5) = 9/100
= 2x+5 / x²+5x = 9/100
= 100(2x + 5) = 9(x² + 5x)
= 200x + 500 = 9x² + 45x
= 9x² - 155x - 500 = 0
= 9x² - 180x + 25x - 500 = 0
= 9x(x - 20) + 25(x - 20) = 0
= (9x + 25) (x - 20) = 0
= x = -25/9 or x = 20
Time can't be in negative so -25/9 is rejected.
Now,x + 5 = 20 + 5 = 25
In short, Your Larger pipe takes 20 minutes and smaller pipe takes 25 minutes
Hope this helps!
Answer:
x = 44°
Step-by-step explanation:
2x - 6 = 82
2x = 82 +6
2x = 88
divide through by 2
x = 44°
