Answer:
2080
Step-by-step explanation:
The solution to these equations might best be found using Cramer's Rule. It tells you ...
x = (56939×3 -41655×2)/(-236×3 +838×2) = 87507/968 ≈ 90.400
This is years after 1990, so the year the incomes become the same is predicted to be ...
1990 +90.4 = 2080.4
The median incomes will be the same in the year 2080.
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.
