Step-by-step explanation:
Answer: 2
Step-by-step explanation:
Cavalieri's Rule tells us that it doesn't matter if the shape is oblique or not, the volume is still found using the regular volume formula. For a pyramid, this formula is V = 1/3 Bh, with B being the area of the base which is a rectangle. The area is 10*12 which is 120, and the height is given as 8. So the volume is V = 1/3 * 120 * 8, which is 320 units cubed.
Lisa would get $3.84 in change.
2.23 x 2 + (2.23 - .53) = 6.16
10 - 6.16 = 3.84
Answer:
x = 10/3
y = 2/9
Step-by-step explanation:
x + 3y = 4
2x - 3y = 6
Adding both equations gives:
3x + 0y = 10
Solving for x and y:
x = 10/3
y = 2/9
