All Teachers are picky ,anyways here is the answer A = bh
Plug in what we know:
18 1/3 = 3 1/3b
Divide 3 1/3 to both sides:
(18 1/3) / (3 1/3) = b
Convert both of them into improper fractions:
55/3 / 10/3 = b
Flip the 2nd fraction and multiply:
55/3 * 3/10 = b
Multiply the numerators and denominators together:
165/30 = b
Convert to a mixed number:
b = 5 1/2
Answer:
8
Step-by-step explanation:

-10(-4-2j)
-10(-4)-10(-2j)
40+20j
Answer:
The new pyramid has a volume that is 8 times the volume of the original pyramid
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z ----> the scale factor
V_1 -----> volume of the original pyramid
V_2 -----> volume of the new pyramid
In this problem we have that each of the dimensions of the original pyramid are doubled
so
so
substitute
therefore
The volume of the new pyramid is 8 times the volume of the original pyramid
