Answer:
Only Glass B is large enough
Step-by-step explanation:
For repetitive calculations, I like to use a calculator or spreadsheet. The attachment shows the volumes for the three glasses. Only Glass B has a volume that exceeds 75 cubic inches.
__
Note that Glass A has a diameter of 5 inches, so a radius of 2.5 inches.
The answer I got is 155.5. First I broke this into a rectangle ad a trapezoid. The rectangles area is 15x5 = 75. The area of the trapezoid is 1/2(8+15)7 = 23x3.5 = 80.5. So 80.5 + 75 = 155.5
x+4+3x=72
4x+4=72
4x=72-4
4x=68
4x/4=68/4
x=17
Answer:
<h2>8h 35min</h2>
Step-by-step explanation:
11. 180-73 = 107
10. 180-107=73
12. 180-73=107
13. 5x + 20 + B = 180 -> B = 180 - 20 - 5x and 3x+66 + B = 180 -> 3x+66+ (180 - 20 - 5x) = 180 -> 222-180 = 2x -> x = 21
14. ABC = 5x + 20 = 5*21+20= 125
15. ABE = 3x+66 = 3*21+66 = 129
