dlinn [17]

Answer:

I think the answer would be -1/2 or D.

Step-by-step explanation:

Use this formula for calculating slope : y2-y1 / x2 - x1

1. label the pairs, 1 and 2

(-6, 1) - ( x1, y1 ) or (4,-4) - (x1, y1)

(4,-4) - ( x2, y2) (-6,1) - (x2, y2)

(the order does not matter)

2. Than plug in your numbers

y2-y1 / x2 -x1 y2-y1 / x2 -x1

-4 - 1 / 4 - (-6) or 1 - (-4) / -6 - 4

= -5/10 or -1/2 = - 5/-10 or -1/2

im only in eight grade so i did my best explaining , and this hope it helps :)

A game has a circular playing area in which you must hit a ball into a circular hole. The area of the playing area is 16ft2. The

Bad White [126]

Answer:

$4.9\%$

Step-by-step explanation:

we know that

To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area

Let

x ----> the area of the hole

y ----> the area of the playing game

so

$P=\frac{x}{y}$

we have

$y=16\ ft^2$

<em>Find the area of the hole</em>

The area of the circle (hole) is equal to

$A=\pi r^{2}$

we have

$r=1/2=0.5\ ft$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$A=(3.14)(0.5)^{2}$

$A=0.785\ ft^2$

<em>Find the probability</em>

$P=\frac{x}{y}$

we have

$x=0.785\ ft^2$

$y=16\ ft^2$

substitute

$P=\frac{0.785}{16}$

$P=0.0491$

Convert to percentage

$0.0491*100=4.91\%$

Round to the nearest tenth

$4.9\%$
