1) fill the two pools below with water.
assume the dimensions of each 5 foot deep pool to be:
• the isosceles triangle pool: 20ft by 35ft
• the equilateral triangle pool: 40ft by 60ft
problem:
how water is necessary to complete the project.

1750+600 so around 
2350 feet squared of water 

Area of any triangle:
A = 1/2 b h

The dimensions are the b and h, it doesn't matter which is which since you're multiplying.
isosceles: A = 1/2(20)(35) = 350ft²
equilateral: A = 1/2(40)(60) = 1200ft²

Multiply each by 5ft to get the volume
350ft² * 5ft = 1750ft³
1200ft² * 5ft = 6000ft³

Add those together to get 7750ft³ of water.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
