Twelve colored cubes are arranged in a row. There are 3 blue cubes, 2 yellow cubes, 3 red cubes, and 4 green cubes, but not in t

Mashutka [201]

Answer:

The sixth cube from the left is a green cube.

Step-by-step explanation:

There are 12 cubes, 3 blue cubes, 2 yellow cubes, 3 red cubes, and 4 green cubes.

Let B, Y, R and G represent blue, yellow, red and green cubes respectively.

The arrangement will be predicted with the information provided

- There is a yellow cube at one end and a red cube at the other end. There are two models to this.

Y, , , , , , , , , , , R

R, , , , , , , , , , , Y

- The red cubes are all touching. Note that there are 3 red cubes

Y, , , , , , , , , R, R, R

R, R, R, , , , , , , , , Y

- The green cubes are also all touching and the tenth cube from the left is blue.

We first position the blue cube at a position tenth from the left

Y, , , , , , , , , R, R, R

With this configuration, the blue cube will be taking the position of a red cube and that violates the rule that the 3 red ctubes are touching, Hence, it is evident that the 2nd model we're examining is the correct one

We then position the blue cube at a position tenth from the left in the 2nd model

R, R, R, , , , , , , B, , Y

Then all the 4 green cubes are touching, they could be placed in a number of ways

R, R, R, G, G, G, G, , , B, , Y

R, R, R, , G, G, G, G, , B, , Y

R, R, R, , , G, G, G, G, B, , Y

Note that in each of the 3 possible ways this can happen, the sixth cube from the left is always a green cube.

Hence, the sixth cube from the left is a green cube.

Hope this Helps!!!

80% of x is equal to 100. Write an equation that shows the relationship of 80%, x, and 100

wariber [46]

Answer:

<u>The number is 125 and the equation is 0.8x = 100</u>

Step-by-step explanation:

80% of x is equal to 100.

Write an equation that shows the relationship of 80%, x, and 100

80% = 0.8

0.8x = 100

x = 100/0.8

x = 125

<u>The number is 125 and the equation is 0.8x = 100</u>
