With a proportion set up to equal like this, you would cross multiply 21*500 which will equal 10,500. Then take 10,500 and divide it by 100 which will give you 105. 105 out of 500 is your answer equal to 21 out of 100.

Answer:

105

Step-by-step explanation:

500 goes into 100, 5 times

21 times 5 is 105

So 21/100 is equal to 105/500

Or you can do

500*0.21=105

A circle has its center at (6,-3). One point on the circle is (3, 1).

Komok [63]

Answer: A (10,-6)

Step-by-step explanation:

step 1:- The equation of the circle is given center and radius is

$(x-h)^{2} +(y-k)^{2} = r^{2}$

Step 2:-

A circle has its center at (6,-3) and point on the circle is (3,1),Now

we have find radius from center to the given point on the circle

The distance of two points are

$\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1} )^2 }$

$\sqrt{(1-(-3))^2+(3-6)^2}$

$\sqrt{25}$

$r=5$

step 3:-

The equation of the circle having center and radius is

$(x-6)^{2}+(y+3)^2=5^{2}$

verification:

This circle is passing through the point (10,-6)

$(10-6)^{2}+(-6+3)^2=25$

$25 =25$

There fore the another point that lies on the circle is (10,-6).
