Answer:
The two numbers are .8*160=128 and .85*240=204
Step-by-step explanation:
First sentence: x+y=400
Second sentence .8x+.85y=400-68
Solve y in the first sentence: y=400-x
Plug first into second: .8x+.85(400-x)=332
Distribute: .8x+.85(400)-.85x=332
Combine like terms: -.05x+.85(400)=332
Simplify(multiply): -.05x+ 340=332
Subtract 340 on both sides: -.05x =332-340
Simplify(subtract): -.05x =-8
Divide both sides by -.05: x =-8/-.05
Simplify (division): x = 160
So y=400-x=400-160=240
To estimate the volume of Thai triangular prism you will use the formula for finding the volume.
V=Bh, where B is the area of the base and h is the height of the prism.
V = (1/2 x 12.6 x 1.6) x 10.75
V = 108.36 cubic mm
You answer is approximately 108 cubic millimeters.
