Answer:
a,e
Step-by-step explanation:
let length=l
width=w
height=h
surface area=2(l+w)×h+2×l×w
=2[lh+wh+lw]
2(8×4+4×3+8×3)=2(32+12+24)=2×68=136<160
2(7×6+6×4+7×4)=2(42+24+28)=2×94=188>160
2(3×7+7×8+3×8)=2(21+56+24)=2(101)=202>160
2(3×6+6×7+3×7)=2(18+42+21)=2(81)=162>160
2(3×5+5×7+3×7)=2(15+35+21)=2(71)=154<160

The is a 1/4 chance of flipping Heads Twice.
Answer:
Step-by-step explanation:
volume of a pyramid is V=(lwh)/3
If two triangles are similar, then their side lengths are proportional.
RS / JK = RT / JL
5 / x = 4 / 7
4x = 35
x = 35/4 = 8.75
RT / JL = TS / LK
4 / 7 = 6 / (y + 2)
42 = 4(y + 2)
42 = 4y + 4
4y = 38
y = 38/4 = 9.5
LK = 9.5 + 2 = 11.5 cm
JK = x = 8.75
Hope this helps!
Answer:
8
Step-by-step explanation:
Ok... So this is about as simple as it gets. If you look at BE and ED, you can see the little red lines on them. That means that they are congruent. So if BE=8, then so does ED.
If you need help with anymore problems (or my explanation just doesn't make sense) just let me know.
