Answer:

Step-by-step explanation:

Since we are given self defining variables, h is obviously referring to the plant's height and y is referring to the plant's years or age.

Then, since a plant's height is 1.4 times its age, age multiplied by 1.4 should be the plants height.

The equation would come out to $h=1.4y$

a rectangular tank can be filled with water by two pipes in 100/9 minutes.If the large pipe alone takes 5 minutes less to fill t

Kitty [74]

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!
