Answer:
608 cm^2
Step-by-step explanation:
<em>Top and bottom rectangles: </em>
2(10*16)
= 2(160)
= 320
<em>Middle rectangle:</em>
(12*16)
= 192
<em>Two triangles:</em>
2((12*8)/2)
= 2(96/2)
= 96
<em>Surface area of the whole prism:</em>
320 + 192 +96
= 608
d = dimes
q = quarters
d+q = 38 coins
q=38-d
0.25q + 0.10d=6.95
0.25(38-d)+0.10d=6.95
9.5-0.25d+0.10d=6.95
-015d=-2.55
d=-2.55/-0.15 = 17
q=38-17 =21
21*0.25 =5.25
17*0.10 = 1.70
5.25+1.70 = 6.95
she had 21 quarters and 17 dimes
Y= -2(x)+7 I'm pretty sure....
0.8/1.2 = 0.6667
1 - 0.6667 = 0.3333
It is 33.33 % off
