The floor of a rectangular hall has a perimeter of 150m. if the cost of painting the four walls at the rate of rupees 10 m^2 is rupees 9000. find the height of the wall

Hey!

Height - 6m

Solution-perimeter=2(a+b)=150m

So a+b=75

And a=75-b

Now total area of 4 walls =9000/10=900

Let height be c

So 2(ac+bc)=900

ac+bc=450

(75-b)c+bc=450

C=450/75=6m

Hope this helps!

answer: huh

step-by-step explanation:

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
