Answer:

66.66

Step-by-step explanation:

So for this one all you really have to do is turn 2/3 into a precent which is pretty easy.

This fist step to this would just be dividing 2 and 3

2/3=0.66666666666666666666 (and on and on and on)

Now just move the decimal 2 times to the right

66.6666666666666666666666

And of course round it, and in this case to the hundreth place

66.66

Circle C has a center at (-2,10) and contains the point P(10,5). Which equation represents circle C?

Rina8888 [55]

Answer:

The equation that represents circle C is $(x+2)^2+(y-10)^2=169$ .

Step-by-step explanation:

A circle is the set of all points in the plane which maintains a fixed finite distance <em>r</em> from a fixed point <em>O = (a, b)</em>. Here <em>O</em> is called the center, and <em>r</em> is called the radius of that circle.

The standard equation for a circle with center (a, b) and radius <em>r</em> is

$(x-a)^2+(y-b)^2=r^2$

We are told that the center of this circle is (-2, 10), so

$(x+2)^2+(y-10)^2=r^2$

We are also told that the circle contains the point (10, 5), so we will use that information to find the radius <em>r.</em>

<em /> $(10+2)^2+(5-10)^2=r^2\\\\r^2=\left(10+2\right)^2+\left(5-10\right)^2\\\\r^2=12^2+5^2\\\\r^2=144+25\\\\r^2=169\\\\r=\sqrt{169}=13$ <em />

Therefore, the equation that represents circle C is

$(x+2)^2+(y-10)^2=13^2\\\\(x+2)^2+(y-10)^2=169$

Suppose you cut a square into two rectangles as shown below. Write an expression for the area of the square

Hunter-Best [27]

The area of each rect. would be xy, so the total area of the square would be 2xy, by definition of area of a square

2х + Зу = 24<br> What is the x and y intercept

DochEvi [55]

Answer:

rearrange into y=mx+c

so it becomes

3y= -2x+24

y= (-2/3)x+24

substitute values for x

when x is 0

y is (-2/3)*0=0 +24 =24

for x intercept

0=(-2/3)*x+24

0-24=-2/3*x

-24/(-2/3)=x

Answer:

15 days

Step-by-step explanation:

Total hours required =

16×5×6 = 480

480 = n×8×4

480 = 32n

n = 480/32

n = 15
