Your two equations would be:
150 = x + y
2560 = 20x + 12y
after solving,
95 for $20
55 for $12
Answer:
40°, 140°, and 140°
Step-by-step explanation:
For similar triangles, the ratio of the corresponding sides are equal. To determine the common ratio, we take the square root of the ratio of the given areas.
ratio = sqrt (384 / 1057)
ratio = 384/1057
Then, for the volume, we have to cube the ratio calculated above. If we let x be the value of the volume of the smaller solid.
(384/1057)^3 = x/1795
x = 86 yd
Thus, the volume of the smaller figure is 86 yd³.
Answer:
A
Step-by-step explanation:
40×10=40
2×1=2
5×1/10=0.5
2×1/100=0.09
3×1/1000=0.003
40+2+0.5+0.09+0.003=42.593
That is absolutely correct
