Answer:

Step-by-step explanation:

Alright, this one should be fairly simple and quick to solve.

8/2= (2+2)

First, we need to do what is in the parenthesis before we do anything else.

2+2= 4.

So now we have:

8/2 (4)

Next we will divide eight by two.

8/2=4

Now:

4(4)

For the last step, we will distribute four to four.

4 x 4

= 16.

The answer to our equation is 16.

Answer: if you simplify the equation, your answer should be 16

Step-by-step explanation: Simplify  2+22+22+2  to  444.

8÷2×48\div 2\times 48÷2×4

2

Simplify  8÷28\div 28÷2  to  444.

4×44\times 44×4

3

Simplify.

16

Step-by-step explanation:

A cluster sample occurs when the intended population is divided into   non- overlapping sub -groups or clusters and some of these clusters are represented in the sample.

From the question, In a state 15 high schools where randomly selected and  the standardized test was administered to only 10th grade student. Here, the  high schools  are the non-overlapping sub groups that is randomly selected and a reasonable representation of the  entire subgroups.

A triangular piece of rubber is stretched equally from all sides, without distorting its shape, such that each side of the enlar
OverLord2011 [107]

Answer:

The area of the enlarged triangle is 4 times the original area

Step-by-step explanation:

we know that

The scale factor is equal to divide the measurement of the length side of the enlarged triangle by the the measurement of the length of the corresponding side of the original triangle

In his problem

Let

x------> the length side of the original triangle

so

2x----->  is the length of the corresponding side of the enlarged triangle

scale\ factor=\frac{2x}{x}=2

scale\ factor> 1 -------> that means is increasing

The scale factor squared is equal to the ratio of the area of the enlarged triangle divided by the area of the original triangle

so

Let

m-------> the area of the enlarged triangle

n------> the area of the original triangle

r-------> scale factor

r^{2} =\frac{m}{n}

we have

r=2

substitute

2^{2} =\frac{m}{n}

m=4n

therefore

The area of the enlarged triangle is 4 times the original area

Allisa [31]

Answer:

Step-by-step explanation:

We have to write an equation which represents the area of Felicia covered y in terms of the number of tiles she used.

Let x= Number of tiles

y=Area  covered by  Felicia's tile

x_1=9, x_2=18, x_3=27

y_1=1, y_2=2,y_3=3

\frac{x_1}{y_1}=\frac{9}{1}=9

\frac{x_2}{y_2}=\frac{18}{2}=9

\frac{x_3}{y_3}=\frac{27}{3}=9

The ratio of x and y remains constant.Therefore, it is direct proportion .

Equation of direction proportion is given by

\frac{x}{y}=k

Where

k=The value of ratio of x and y

x and y are variables

We have k=9

Substitute the values in the equation

Then, we get

\frac{x}{y}=9

x=9y

y=\frac{1}{9}x

This is required equation which representing the area of Felicia covered y in terms of the number of tile she used x.
