Answer:
3.375
Step-by-step explanation:
The amount of material it took to build the cube is the same as the surface area. Since a cube has 6 congruent faces we can divide to find the area of one face.
13.5/6 = 2.25m.
2.25m is the area for each face of the cube.
Each face is square and has an area of 2.25m. To find the length of each side of the square we can take the square root. The square root of 2.25 is 1.5. The length of each side of the square is 1.5 metres.
To find the volume of the cube, we can use the formula V = lwh.
V = lwh
V = 1.5*1.5*1.5
V = 3.375
The volume of the giant sugar cube is 3.375m.
Answer:
The level was 402.7ft. at the end of two weeks.
Step-by-step explanation:
First, we need to find the amount of decrease for the first week.
520 x 0.12 = 62.4
Now, we subtract the change for the first week.
520 - 62.4 = 457.6
Next, we find the change for the second week.
457.6 x 0.12 = 54.912
Then, we subtract the change for the second week.
457.6 - 54.912 = 402.688
And we are left with our final answer that is 402.688ft. or if you wish to round to the nearest tenth, then your answer would be 402.7ft.
Answer:
95
Step-by-step explanation:
35+50= 85
180-85=95
Answer:
y = 2x - 5
Step-by-step explanation:
Using the slope intercept formula y2 - y1 / x2 -x1...
You get a slope of 2 so y = 2x +b
Then to find b the intercept, you plug in one of the coordinates like so...
1 = 2(3) + b
Then solve to get an intercept of -5.
So the slope-intercept form would be...
y = 2x - 5
