The diameter is 10:

To do this we must use the distance formula:

Distance =√(x2−x1)^2+(y2−y1)^2

So, if we substitute in our values for the origin and endpoint (origin is 1 values, endpoint is 2)

D=✓(-4-0)^2+(-3-0)^2

Simplified, this is

D=✓16+9
D=✓25
D=5

so, the distance from the center of the crcle to the endpoint is 5 (making the radius)

multiply by two, and the diameter of the circle is 10 :)

4x+2(3x-9)=42 what is x equal
katrin2010 [14]
<span>4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
</span><span>10x-18=42
we add 18 to both sides
10x=60
divide both side by 10

G=h(t) + p(c) is an equation that represents the gross pay of a server: Gross pay = hourly wage (time worked) + percent tip (cos
rusak2 [61]

Answer:

$105.5  for 16 hours at $6.59 per hour

Step-by-step explanation:

form the equation given, G=h(t) + p(c)

where G=Gross pay,

            h= hourly wage

            t=time worked

             p=percent tip

             c=cost of customer meals

we determine the gross pay by first determining the independent variables

h=$4.25, t=16 hours,

p=15%of c\\p=\frac{15}{100}*250 \\p=37.5

if we substitute values, we arrive at

G=h(t)+p(c)\\G=4.25(16)+37.5\G=68+37.5\\G=105.5

to determine the per hour gross pay we have

105.5/16

hourly gross pay,G=$6.59

*PLEASE HELP MEEEEEE* You throw a dart at the board shown. Your dart is equally likely to hit any point inside the square board.
yawa3891 [41]

Answer:

19.63%

Step-by-step explanation:

The probability of scoring 8 points is the probability of getting a dart into the green circle.

That probability is equivalent to the area of the circle divided by the total area of the square board.

The area of the circle according to A=\pi*r^2, is 25\pi cm squared

The area of the whole square board is one side squared: 20 squared = 400 cm squared

The probability is therefore equal to 25\pi/400 = \pi/16=0.19634=19.63%%
