5. A cube has width of 8 cm. What is the volume of the cube?
Anyone got an answer?
Answer:
8×8×8 =512
Step-by-step explanation:
prove me wrong
Answer:
512 cm
Step-by-step explanation:
the formula to find volume is length × width + height (L×W×H) and since it is a cube all of the sides are equal so simply multiple 8 × 8 × 8 to get 512

find the value of x.
Answer:
2
Step-by-step explanation:
Since they are similar triangles then the ratio will be the same on all sides.
You know the one side 5 is the same ratio to 5x so you multiply x to all sides of the little triangle to get the value of the equivalent side in the big one.
so the missing side x times x will equal the big size of the bigger triangle which is 4
x times x = 4 can only be 2
HELP PLEASE! Write a quadratic function that passes through the point (-1,9), has an axis of symmetry of x=-3 and a minimum value of 7.
Answer:
[tex]y = \frac{1}{2}x^{2} - 3x + 11.5[/tex]
Step-by-step explanation:
Vertex Form of a quadratic equation;
[tex]y = a( x - h )^{2} + k[/tex]
Vertex of the parabolas (h, k)
The vertex of the parabola is either the minimum or maximum of the parabola. The axis of symmetry goes through the x-coordinate of the vertex, hence h = -3. The minimum of the parabola is the y-coordinate of the vertex, so k= 7. Now substitute it into the formula;
[tex]y = a ( x + 3 ) ^{2} + 7[/tex]
Now substitute in the given point; ( -1, 9) and solve for a;
[tex]9 = a( (-1 ) + 3)^2 + 7\\9 = a (2)^{2} + 7\\9 = 4a + 7\\-7 -7\\2 = 4a\\\frac{1}{2} = a\\[/tex]
Hence the equation in vertex form is;
[tex]y = \frac{1}{2}(x - 3)^{2} + 7[/tex]
In standard form it is;
[tex]y = \frac{1}{2}x^{2} - 3x + 11.5[/tex]

Which statements are true?
Select each correct answer.
Since −6 is 6 units to the left of 0, |−6|=6 .
The absolute value of −6 is negative.
The absolute value of −6 is less than the absolute value of 6.
−6 is closer to zero on the number line than −7 , so |−6|<|−7| .
Answer:
The first one and the last one are true (Since −6 is 6 units to the left of 0, |−6|=6 and −6 is closer to zero on the number line than −7, so |−6|<|−7|.)
Step-by-step explanation:
Absolute value is the distance to zero, and it is always positive. That means the positive and negative versions of a number have the same absolute value. That means the first one is true, and the second and third ones are false. For the last one, -6 is closer to zero, so that means it would be true (The absolute value of -6 is 6, and the absolute value of -7 is 7).
Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking. How much butter was left after she was done baking?
Answer:
[tex]\dfrac{5}{8}[/tex] butter was left after she was done baking.
Step-by-step explanation:
Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking.
We need to find how much butter was left after she was done baking.
It can be calculated as follows,
Left =
[tex]=\dfrac{7}{8}-\dfrac{1}{4}\\\\=\dfrac{7}{8}-\dfrac{2}{8}\\\\=\dfrac{7-2}{8}\\\\=\dfrac{5}{8}[/tex]
Hence, [tex]\dfrac{5}{8}[/tex] butter was left after she was done baking

Answer:1. 1.0 1.0 1.4
Step-by-step explanation:
The length of the sides are given by the 45°–45°–90° triangle theorem.
Correct responses:
AB = 1AC = 1BC = √2 Methods used to find the lengthsThe 45°–45°–90° triangle theorem states that the ratio of the lengths of
the sides of triangles having interior angles of 45°, 45°, 90° is 1 : 1 : √2
The lengths of the legs of an isosceles triangle are equal.
The legs of the given isosceles right triangle are AB and AC
Therefore;
AB = AC
Taking the lengths of AB as 1 unit, we have;
AB = 1 = AC
According to Pythagorean theorem, we have;
[tex]\overline{BC}^2 = \mathbf{\overline{AB}^2 + \overline{AC}^2}[/tex]
Which gives;
[tex]\overline{BC}^2 = 1^2 + 1^2 = \mathbf{ 2}[/tex]
Therefore;
BC = √2
Therefore, by setting the length of AB = AC = 1, we have;
AB = 1AC = 1BC = √2 ≈ 1.414The above values are in the ratio 1 : 1 : √2, which corresponds with the
45°-45°-90° triangle theorem.
