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:
x=-4
Step-by-step explanation:
The axis of symmetry is a vertical line through the vertex with. It is written as x = h where h is the x-coordinate of the vertex.
Here the vertex is (-4,-6). So the axis of symmetry is x = -4
-9.2(8x - 4) + 0.7(2 + 6.3x)....distribute thru the parenthesis
-73.6x + 36.8 + 1.4 + 4.41x ...combine like terms
(-73.6x + 4.41x) + (36.8 + 1.4) =
-69.19 + 38.2 <====
Pat attention to the ending of the numbers. If there are an odd amount of odds, it's going to be odd. If there is an even amount of odds, it's going to be even. If there's only evens, it's only going to stay even.
In 1980, wind turbines in Europe generated about 5 gigawatt-hours of energy. Over the next 15 years, the amount of energy increased about 59% (each year). How many gigawatt-hours were generated
