Answer:
5 cubes
Step-by-step explanation:
The volume of a square pyramid is given in terms of its side length (s) and height (h) as ...
V = (1/3)s^2·h
For the given measurements, the volume is ...
V = (1/3)(9 cm)^2 ·(10 cm) = 270 cm^3
___
The volume of each cube of wax is the product of its length, width, and height, so is ...
V = (4 cm)^3 = 64 cm^3
___
Then the number of wax cubes required to fill the pyramid is ...
(270 cm^3)/(64 cm^3/cube) = 4 7/32 cubes
Four cubes are not quite enough to make the candle.
Devin will need 5 cubes to make the candle.
A discontinuity occurs when the denominator equals zero
it will be either a hole or an asymptote
x+4 = 0
subtract 4 from each side
x=-4
Answer:
Step-by-step explanation:
<A = <C
The angles meeting at B and are part of the triangle are vertically opposite and therefore equal.
<E and <D are equal. (given)
Therefore by angle angle angle, the two connected triangles are similar
AD/CE = 12/x from <A = <C
27/23.4=12/x Cross Multiply
27x = 12*23.4 Combine the Right Side
27x = 280.8 Divide by 27
x = 280.8/27
Answer: x = 10.5 cm
