The radius is 4
the equation of a circle is (x-h)^2+(y-k)^2=r^2
in this case, 16=r^2
so r=4

16^2 is the radius, so 16 squared is 4. Therefore the radius is equal to 4

I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST! A circle has a diameter AB, and its center is at (-3, 3). Point A is at (1/2,6)

kow [346]

Using the mid-point concept, it is found that point B is located at coordinates (-6.5, 0).

<h3>What is the midpoint concept?</h3>

The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.

The center is the midpoint of the two coordinates of the diameter, hence:

$C = \frac{B + A}{2}$

For the x-coordinate:

$-3 = \frac{x + 0.5}{2}$

x + 0.5 = -6

x = -6.5

For the y-coordinate:

$3 = \frac{y + 6}{2}$

y + 6 = 6

y = 0

The rubber playground mulch is sold in packages that cover 300 square feet each. what expression represents the number of packag

tino4ka555 [31]

The expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x

<h3>How to determine the expression represents the number of packages of mulch that will be needed to cover both rounded ends?</h3>

The given parameters are:

Area covered = 300 square feet

Number of ends = 2

So, the total surface area is:

Total surface area = Area covered * Number of ends

This gives

Total surface area = 300 * 2

Total surface area = 600 square feet

Let the area covered by each package of mulch be x.

So, the number of mulch is

Number = Area covered/area covered by each

This gives

Number = 600/x

Hence, the expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x

What is the value of x in the equation 1/5x – 2/3y = 30, when y = 15?

Maksim231197 [3]

X=200
2/3 of 15 is 10 make that negative add it to the other side 1/5x = 40 and then multiply 40 by 5 to get your answer
Check
1/5 of 200 is 40 - 10 = 30
40-10=30
30=30
