-- XY is a "diameter" of the circle. 

-- A diameter is any straight line inside the circle that goes
through the center and touches the curvy part twice.

-- Every diameter of the same circle has the same length.

-- The distance around every circle is (its diameter) multiplied by (pi).


-- Half of the diameter is called the "radius" of the circle.
A radius is any straight line inside the circle that goes between
the center and the curvy part.

-- The area of every circle is  (its radius, squared) times (pi).

-- 'Pi'  ( π )  is a number.  It's a decimal that keeps going forever
and never ends, so you can never write it exactly with numbers.

-- Pi is roughly 3.14 , and if you use 3.14 whenever you need pi,
then your answers will be about  0.05%  too small. 

That's very close.  When you turn in an answer that's only
0.05% wrong, the teacher knows that you know how to solve
the problem, and that's way more important than the answer.  

For the circle in your picture, the diameter is 17in, the radius
is 8.5in, and the area must be  (pi) (8.5)² square inches.
You can go ahead and work that out.

(4/x - z/y=0) <br> (10/x+z/y=0)
galina1969 [7]

Answer:

Some of the other answers are good examples of solving a system of three equations in three unknowns, which is what this problem is asking. Though the simplest way to solve this problem is actually to notice that, if we sum the three equations, we get:

 

   X + Y = 10

   X + Z = 20

+  Y + Z = 24

----------------

2X + 2Y + 2Z = 54

 

Factoring out the 2, we have 2(X + Y + Z) = 54, and dividing both sides by 2 reveals that X + Y + Z = 27.

Step-by-step explanation:

hopefully this helps

Can I get a help please ​
iogann1982 [59]

Answer:

middle graph

Step-by-step explanation:

Soluton

The  second (middle ) graph is the only one that works.

  • First of all when you simplicity the right, you get y = x^2 - 1). That means that x does not go through 0,0. If you put x = 0 into x^ -  1 = 0, you get - 1. So on that basis alone both the first and third graphs are incorrect.
  • Second, both xs in the factors are plus, so x^2 is plus, which means the graph opens upward.

A hardware store sells light bulbs in different quantities. the graph shows the cost of various quantities. according to the gra
skelet666 [1.2K]

Looking at the two black dots

5 bulbs cost $9

Divide total cost by number of bulbs bought:

9 / 5 = $1.80 per bulb.

10 bulbs cost $18

Divide total cost by number of bulbs bought:

18 / 10 = $1.80 per bulb

The cost for one bulb is $1.80
