The formula for a circle is (x-h)^2 + (y-k)^2 = r^2 where h is x-value and k is the y-value of the center.

If diameter is 24, the radius is 12

(x + 9)^2 + (y - 5)^2 = 144

Find the equation of the line that is perpendicular to the line x=-7 and contains the point (-6,8)
Alex73 [517]

Answer:

The equation would be y = 8

Step-by-step explanation:

Since the line x = -7 is a vertical line, we know that any line perpendicular to it would be horizontal. All horizontal lines can be written as y = (a number). Since we have an ordered pair that is on the line, we can find that number as the y value in that pair.

y = 8

Solve the system of equations by substitution:<br> y = 3x – 7<br> 6x- 2y= 12
Pie

Answer: no solution

y=3x-7

6x-2y=12

6x-2(3x-7)=12

6x-6x+14=12

14=12

A rubber ball has a radius of about 2.86 in. Can the ball be packaged in a box shaped like a cube with a volume of 125 in3?
Vlada [557]

Answer:

I am not sure what the values needed to add in / etc, but here is the height of the box: 5

Step-by-step explanation:

A cube is a kind of rectangle where all the sides are the same. So to find volume, cube the length of any side. To find height, calculate the cube root of a cube's volume. For this example, the cube has a volume of 125. The cube root of 125 is 5. The height of the cube is 5.

(hopefully this is correct, have a nice day!)

Bill is in a class of 15 boys and 35 girls 40 percent of the students in the class take the bus to school how many students do n
GREYUIT [131]

the gender of the kids does not matter so it can be discarded.

you add up how many boys and girls in the class to make a total of 50 kids

your 100% is 50

meaning 40% of 50 is 20

so if 20 kids took the bus to school then 30 did not take the bus.
