I believe the lateral surface area is 87.96.
9514 1404 393
Answer:
B, F
Step-by-step explanation:
The volume is the product of the dimensions:
V = LWH
V = (b^2)(3c^2)(2c^1) = (3·2)(b^2)(c^(2+1))
V = 6b^2·c^3 . . . . . matches B
__
For b=3 and c=2, the volume is ...
V = 6(3^2)(2^3) = 6(9)(8)
V = 432 . . . . cubic inches . . . . matches F
Should be somewhere around there either way for 9. the angles are the same because you see the arrows on the parallel lines 8. I'm not quite as sure about
Answer:
11 yrs
Step-by-step explanation:
Mean = sum of ages/number of ages
Let the age of the seventh girl be A
Given the addition of the age of the seventh girl will make the mean of the ages be 13,
So,
13 = 17+8+12+15+15+13+A/7
Add up the ages
13 = 80 + A /7
Cross multiply
80 + A = 13 x 7
80 + A = 91
Subtract 80 from both sides to isolate A
80 - 80 + A = 91 - 80
A = 11
The age of the seventh girl is 11
4 3/4 equals 19/4ths so the correct answer would be 19 burgers
