The length of a diagonal of a square is 18√2 inches. Find the perimeter of the square.

Answers

Answer 1

A diagonal of a square is defined, [tex]d=a\sqrt{2}[/tex] where a is side of the square. Solve for a to get [tex]a=\frac{d}{\sqrt{2}}[/tex].

Now multiply a by 4 since that is the definition of a perimeter,

[tex]P=4a=4\cdot\frac{18\sqrt{2}}{\sqrt{2}}=4\cdot18=\boxed{72}[/tex].

Hope this helps.

4x-y=-3 3Y-6x = 6
find ordered pair

Answers

Answer:

(-60/11,111/11)

 

Step-by-step explanation:

Solving simultaneously, 4x - 3y=6   -3(6x + y=42)   then it becomes, 4x - 3y=6

-18x - 3y= 126 subtracting the two equations,   22x= -120, x= -60/11 and y = 111/11

.

Answer:

(-0.5, 1)

Step-by-step explanation:

4x - y = -3    ----------------------(I)

-6x + 3y = 6 -------------------(II)

Multiply equation (I) by 3 and then add. So, y will be eliminated and you can find the value of x.

(I) * 3         12x - 3y = -9

(II)             -6x + 3y = 6          {Now, add}

                6x          = -3

                          x = -3/6

                          x = - 0.5

Plug in x = -0.5 in equation(I)

4*(-0.5) - y = -3

- 2   - y = -3

     -y   = - 3 + 2

    -y   =  -1

     y = 1

What are the advantages and disadvantages of bar chart​

Answers

Answer:

Advantages:

● Bar charts are pretty easy to interpret, and there's a very clear relationship between size and value that allows easy comparison.

● They're simple to make and most people have experience creating and understanding them from school.

● They can help in presenting very large or very small values more emphatically.

Disadvantages:

● Bar charts that attempt to represent wide ranges of numbers will struggle to efficiently communicate their message. For example, a bar chart for the numbers 5, 6, 10 and 378 will lend extreme visual weight to the highest value and make the relative values of the other measurements appear irrelevant. An alternative to this would be creating an adjusting scale for the bars, but this complicates the visual aspect of the presentation and breaks the intuitive sense that size correlates directly to value.

● Bar graphs tend to be locked into a particular data set, making it hard to show multiple values or changes over time unless the chart is modified, such as by making the bars layered and three-dimensional.

Hunter surveyed 200 of the students in his school about their favorite color. 66 students said their favorite color was blue. What percentage of the surveyed students said their favorite color was blue?

Answers

33% because 66/200 is .33, and convert that to percentage by multiplying by 100

The percentage of the surveyed students who said their favorite color was blue is 33%

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: Hunter surveyed a total of 200 students.

Also students with blue as their favorite color are 66

We know percentage is ratio of the quantity involved over the whole multiplied by 100

Thus the number of students with blue as their favorite color in percentage terms is = 66/200 × 100

                                  = 33%

[3x-2]÷4=2x-8

Can someone help

Answers

Answer:

Step-by-step explanation:

[3x-2]÷4=2x-8

3x-2 = 4·(2x-8)

3x-2 = 8x-32

-2 = 5x-32

30 = 5x

x = 6

Answer:

(3x-2)/4= 2x-8  x=6

Step-by-step explanation:

(3x-2)/4 times 4= 2x-8

Multiply both sides by 4

3x-2/4 times 4= 2x  times 4-8 time 4

Simplify

3x= 8x = 8x-30-8x

Subtract 8x from both sides

3x-8x=8x-30-8x

Simplify

-5x=-30

Divide both sides by -5

-5x/-5 = -30/-5

Simplify so you get x=6
