This is asking for the cube root of 64. Another way of phrasing this is "What number cubed is equal to 64?" We know that 2³ is 8, so it must be a number greater than 2. 3³ is 27, it must be larger. 4³ is equal to 64, so 4 is your answer.

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one.

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

- The room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.

2. Therefore, let's call

x: the smaller one.
y: the larger one.

3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:

x+y

4. So, the area of the room is:

(x+y)(x+y)
(x+y)²

Therefore, the answer is: (x+y)²

Of the 120 apartments in a building, 75 have been scheduled to receive new carpet. What fraction of the apartments have not been

Ilia_Sergeevich [38]

Hello!

To find the fraction of the apartments that have not been scheduled to receive new carpet, we need first need find the number of apartments not receiving new carpet, by subtracting the total amount of apartments, by the 75 that have been scheduled.

120 - 75 = 45 apartments

Next, we need to create a fraction. Since 45 out of 120 apartments not are scheduled to get new carpeting, the fraction of these values is 45/120. This can be reduced to 3/8.

Therefore, your final answer is 45/120, simplified to 3/8.

WILL GIVE BRAINLIEST IF CORRECT ANSWER!!!

Rom4ik [11]

Answer : 2√3

Given :-

A equilateral triangle with side length 4.

To Find :-

The value of x in the given figure.

As we know that in a equilateral triangle , perpendicular bisector , angle bisector and median coincide with each other .

So the perpendicular drawn in the figure will bisect the given side .
Therefore the value of each half will be 4/2 = 2 .

Now we may use Pythagoras theorem as ,

→ AB² = BC² + AC²

→ 4² = 2² + x²

→ 16 = 4 + x²

→ x² = 16-4

→ x² = 12

→ x =√12 = √{ 3 * 2²}

→ x = 2√3

Hence the required answer is 2√3 .

I hope this helps.
