Answer:
100g : 60g : 80g
Step-by-step explanation:
5+3+4 =12 total parts 
(5/12 of 240) 
5/12 x 240 = 100g
3/12 x 240 = 60g
4/12 x 240 = 80g
Check:
100g + 60g + 80g = 240g
Hope this helps! 
 
        
             
        
        
        
Answer:
254.5 Inches Cubed
Step-by-step explanation:
Formula for Finding the Volume of a Cylinder: 
The radius is 3 inches.

The height is three times the radius. 
Multiply the radius by three to get the height.

The height is 9 inches. 
Use the formula to find the volume.

The exact volume is 81 inches cubed.
 inches cubed.
 ≈ 254.47
 ≈ 254.47 
254.47 ≈ 254.5
The volume of the cylinder should be about 254.5 inches cubed. 
 
        
             
        
        
        
B 8:00 am 
8:00+1:25=9:25
9:25+25=9:50
9:50+30=10:20
B $240
60×2=120×2=240
        
             
        
        
        
This question is nasty. It sounds like you should be finding area of the figure you see. I'll do that first, although I don't think it's the right answer. (But it might be).
Area Trapezoid = (b1 + b2) * h / 2
b1 = 8
b2 = 12
h = 5
Area Trapezoid = (8 + 12 ) * 5 / 2
Area Trapezoid = 20 * 5/2
Area = 50 square feet.
The problem is that no lumber yard will cut that for you without charging you. The practical answer is 12 * 5  = 60 square feet is what you will have to buy. Then you cut out the triangles for yourself.
