The volume of a cube is 512 cm3 . What is the area, in square centimetres, of each side of the cube?
lesantik [10]

Answer:

Step-by-step explanation:

V of a cube is s^3

V = 512

s = cube root of (V)

s = cube root of 512 cm^3

s = 8

The area of one face of the cube is s^2

s = 8

Area 1 face = 8^2

Area of 1 face = 64 cm^2

8. Find the congruence transformation that maps ∆ABC to ∆A’B’C’. Explain your reasoning
tino4ka555 [31]

In this case, to flip any of the points to map up accurately to the other points, we would have to do a transformation of reflection about the y-axis. The reason behind this is that out of other transformation process, we can only achieve the image of triangle ∆A’B’C’ through reflection.

Dilation will not work since it only changes the size of the object. The shape and position will not affected.

A translation will not work because although the shape can move, it still needs to flip to achieve triangle ∆A’B’C’.

A rotation will also not work because when you rotate it, the shape will still not map over the new one.

<span>
<span>Therefore the only answer to this question would be to reflect triangle ∆ABC about the y-axis.</span></span>

A rectangle swimming pool measures 22.3 feet by 75 feet find the perimeter of the swimming pool using the correct number of sign
Liula [17]
Perimeter = add all the sides

Pool has 4 sides
So
22.3 + 22.3 = 44.6
75+75 = 150
150 + 44.6 = 194.6ft

WILL GIVE BRAINLIEST AND 30 POINTS!!!!!!!!!!!!!!!!
Black_prince [1.1K]
A) The intersection occurs at the same height 'y', so the y of each equation must be equal:

y=y implies <span>2−x = 8x+4. The solution is -2=9x, x = -2/9=2/3, and y = 20/9

(-2/9,20/9)
</span>
B)
X    |   Y1   | Y2
_____________
-3   5    -20
-2   4    -12
-1   3    -4
0    2   4
1    1  12
2    0   20
3   -1  28

C) I would draw each line with the values on the table. Where both lines cross is the intersection point. It should be (-2/9, 20/9)
