The area of a square poster is 30 in.2. Find the length of

of an inch.

in.

The length of one side of the poster is

(Round to the nearest tenth as needed.)

Answers

Answer 1

Answer:

5.48 inches

Step-by-step explanation:

Given that the poster is in the shape of a square.

Area of the square poster = 30 [tex]in^2[/tex]

To find:

The length of side of the poster = ?

Solution:

First of all, let us have a look at the formula for area of a square.

Let the side of square = [tex]x[/tex] inches

Formula:

[tex]Area =Side \times Side[/tex]

Putting the value of the side:

[tex]Area = x\times x\\[/tex]

Putting the value of Area as given in the question statement:

[tex]30 = x^2\\\Rightarrow x =\sqrt{30}\\\Rightarrow \bold{x \approx 5.48\ inches}[/tex]

a squares side are increased by five inches. Find the length of the original square if the perimeter of the new square is 100 inches. Length of side of original square: ______
inches

Answers

Answer:

The length of side of original square is: 20 inches

Step-by-step explanation:

Let x be the length of side of original square

Then x+5 will be the side of new square

Th formula for perimeter is:

[tex]P = 4*side[/tex]

As we know the perimeter of the new square we can use the perimeter to find the value of x

[tex]100 = 4 * (x+5)\\100 = 4x+20\\4x = 100-20\\4x = 80\\\frac{4x}{4} = \frac{80}{4}\\x = 20[/tex]

The value of x is 20 inches.

Hence,

The length of side of original square is: 20 inches

lamp should go?

C

Answers

Hi, you've asked an incomplete question. I attached the missing caption that completes the question.

Explanation:

By looking closely at the caption we notice there are measuring coordinates along the margin of the caption. To find the middle of the chairs, take note of the total coordinate distances between points C and D;

For the vertical axis, the distance is 4For the horizontal axis, the distance is 2

Substracting both differences in distances we get 2 (4-2) so at point (10, 7) we find the middle or halfway between the chairs at points C  and D.

Option D: 66 degrees

Step-by-step explanation:

Interior angles of a triangle add up to 180 degrees.

Thus, 90+24+x=180 would be the equation you make to solve:

90+24+x=180

114+x=180

x=66

So <x=66 degrees

-9x - 5y = 26

Answer:

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Algebra I

Solving systems of equations using substitution/eliminationSolving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

-9x - 5y = 26

4x - 4y = -24

Step 2: Rewrite systems

4x - 4y = -24

Add 4y to both sides:                    4x = 4y - 24Divide 4 on both sides:                 x = y - 6

Step 3: Redefine systems

-9x - 5y = 26

x = y - 6

Step 4: Solve for y

Substitution

Substitute in x:                    -9(y - 6) - 5y = 26Distribute -9:                       -9y + 54 - 5y = 26Combine like terms:           -14y + 54 = 26Isolate y term:                     -14y = -28Isolate y:                              y = 2

Step 5: Solve for x

Define original equation:                    4x - 4y = -24Substitute in y:                                     4x - 4(2) = -24Multiply:                                                4x - 8 = -24Add 8 to both sides:                            4x = -16Divide 4 on both sides:                       x = -4

X     Y

To fill in the Y values using the function rule y = 4 + 4x, we substitute the given X values into the equation and solve for Y.

When the value of X = 2:

4 + 4(2) = 4 + 8 = 12

When the value of X = 3:

4 + 4(3) = 4 + 12 = 16

When the value of X = 4:

4 + 4(4) = 4 + 16 = 20

When the value of X = 10:

4 + 4(10) = 4 + 40 = 44
