I am assuming you meant to write the equation as (x-11)^2 + (y+15)^2= 144 in which case the answer is 12. The general formula of a circle is (x-h)^2 + (y-k)^2 = r^2 so the value on the right hand side of the equation is the square of the radius. You simply have to take the square root of it

The equation of a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius.
To find the radius, we would find the square root of 144, which is 12.
r=12

blsea [12.9K]

Answer:

He can purchase 300 white baloons.

Step-by-step explanation:

150$ is 15000 cents

15000 = 60b + 30w

b being number of blue baloons,w number of white baloons and 60 and 30 prices in cents

15000 = 60*100 + 30w

15000 - 60*100 = 30w

15000- 6000 = 30w

30w = 9000

w =300

number of white baloons is 300

Andrew uses 630 one-inch unit cubes to completely fill the inside of a rectangular box. Which could be the dimensions of the box
dsp73

we have 630 one-inch unit cubes and we want to completely fill the rectangular box (unknown dimensions).

If all the cubes are fitted tightly inside rectangular box without living any space, then box volume would be equal to cubes volume.

There are 630 one-inch unit cubes, so volume of cubes = 630 cubic inches.

Now the volume of rectangular box would also be 630 cubic inches.

We know the formula for volume of rectangular box = length × width × height.

So we need to find any three positive integers whose product is 630.

Out of all given choices, only option A satisfies the condition of factors of 630.

Hence, option A i.e. (7 in x 9 in x 10 in) is the final answer.

-----
42 6th Graders in either class

  100 6th Graders in total
 -42 6th Graders in either class
-------
58 6th Graders in neither class
 58-42= 16 more 6th Graders that are not in either class
