it would be 48 because you would multiply 8 and 12 but then divide by 2
Answer:
Step-by-step explanation:Sorry but I don't think any of those answers are correct its impossible to solve that
Answer:
ur a hoae that plays gay station
Step-by-step explanation:
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:
on reflection on x axis
P(x,y) = P' (x, -y)
so
(-6, 7) = (-6, -7)
