See the pic-the top two equations are your "system" of equations to solve
Answer:
V /(lw) = h
Step-by-step explanation:
V = lwh
Divide each side by lw
V/ ( lw) = lwh/(lw)
V /(lw) = h
Since the prism completely filled with 2304 cubs
Since the edge of the cube is 1/4 cm
Since the volume of the cube = edge x edge x edge
Then find the volume of 1 cube, then multiply it by the number of cubes to find the volume of the prism

Multiply it by 2304

The volume of the prism is 36 cm^3
Answer:
3800
Step-by-step explanation:
Variables:
O - Original cost
N - New cost
c - change factor
Step 1:
Recognize that if something decreases by 19%, it is worth 19% <em>less</em>
This means that the new price, fractionally, is 100% - 19% = 81%
So we can use c as 0.81 (81/100)
Step 2:
Write an equation to represent what is happening
N = O * c
Step 3:
Sub in what we know
3078 = O * 0.81
Step 4:
Rearange and solve
O = 3078 / 0.81 = 3800
Answer:
0.5 and 2?
4
mph
1.5 and 2.5?
5
mph
Base on these results, the runner ran at a rate between 0.5 and 2 hours than between 1.5 and 2.5 hours.
slower
