Find the length of an apothem of a square if the perimeter is 40.

1 answer:

8 0

An apothem of a square is a perpendicular from a center of a square to one of its side.

1. Put a dot at the center of the square. (You can find the center by drawing diagonals from corner to corner. The center is where they intersect).

2. Draw a perpendicular line in any of the four directions to one side of the square.

3. Two apothems of a square (drawn to opposite sides) make a line that is parallel to both (left) sides of the square, a line that is of equal length. If two apothems added together are equal to the length of one side, then one apothem is half of the length.

4. The square perimeter is 40 and it consists of 4 equal parts, then the length of square's side is 10.

5. Then the apothem has length 5.

A sofa is 900 more than the price of c which system of equation can be used to find price of each piece

Doss [256]

Answer:

$1200

Step-by-step explanation:

S + C = 1200

S = C + 900

C + 900 + C = 1200

2C + 900 = 1200

2C = 300

C = 150

The chair costs $150. The sofa is $1050.

Together they cost $1200.

What are the points for y=-3x+4 and how do I graph it

mestny [16]

Answer:

(-3,13) (-2,10) (-1,7) (0,4) (1,1) (2,-2) (3,5) (4,8) are your graph points.

Step-by-step explanation:

Okay so to find the points, you have to create a table graph with a set of x values.

in this case, your equation y=-3x+4 the x can be replace with a set of numbers and these will be your plots.

-3(-3)+4= 13

-3(-2)+4= 10

-3(-1)+4= 7

-3(0)+4= 4

-3(1)+4= 1

-3(2)+4= -2

-3(3)+4= -5

-3(4)+4= -8

Naturally with these points a shape will form ideally a straight line. Hopefully this helps and good luck!

What is ∛2197? Explain how you got your answer.

user100 [1]

Answer:

Step-by-step explanation:

We need to write our answer in exponential form. Ask yourself the question, "What times itself 3 times will give you 2197?" Your answer is $13^{3}$ . This will go inside of your cube root. You now have $\sqrt[3]{13^{3} }$ . Since there's a power of 3 and a cube root, those cancel each other out, and your answer is 13.
