he answer that you should get is
250+100c+400= y
Are you asking to simplify all of those equations?
The volume of a triangular prism is V = 1/2 x a x c x h where a is height of the triangle, c is the base of the triangle and h is the height of the prism.
120 = 1/2 x a x c x h; we write a from the previous equation in terms of c and h thus,
a = 240 / ( c x h)
If the dimensions where halved then a = a/2 ; c = c/2 ; h=h/2
We use the volume formula again and substitute the given values to find the new volume,
V = 1/2 x a/2 x c/2 x h/2
Substitute the previously determined a term,
V = 1/2 x (240/2ch) x c/2 x h/2
We cancel and evaluate the constants therefore the new volume is,
V= 15 cm^3
Answer:
Step-by-step explanation:
First subtract the 1/x2
Next subtract the fractions on the left
Next Multiply by x1
Next divide both sides by the remaining parts (not x1)
He should need 45 more gallons. 60/4=15 15gallons for every 1/4 of the tank. 60-15=45
