Looking at the image of the cube you can see the outer edges would have paint on 2 sides and the corners would have paint on n3 sides.
The only ones with paint on one pace is the center cubes.
There are 6 sides to a cube and there would be 6 center pieces.
Answer: 6
Answer:
1. (5n^2 x4^n+2)/ 6
2. y=1 y=2
Step-by-step explanation:
Answer:
0.3125
Step-by-step explanation:
There are two different methods:
make an equivalent fraction with the denominator as a power of
10
. This can be
10
,
100
,
1
,
000
,
10
,
000
,
100
,
000
and so on...
5
16
×
625
625
=
3125
10000
Once the denominator is a power of
10
, the number of zeroes indicates how many decimal places there will be.
3125
10000
=
0.3125
←
4
decimal places
This method only works if the denominator is a factor of one of the powers of
10
divide the numerator by the denominator
5
16
=
5
÷
16
=
0.3125
-g00gle I copied and pasted so might look weird
In order to factor a value out of an expression we must divide each term by this value, so ((1/3)*y - 3/2)/-(1/3) = (-1/3)*(-y + 9/2)
