Answer:
It would be about $9
Step-by-step explanation:
you would round $10.80 to $11 because it says to estimate and then you do 20-11 which is 9 so the answer is $9
Answer:
$150
Step-by-step explanation:
First use a proportion to find the answer:
40/100=60/x
Now we solve for x
60*100=6,000
6,000 divided by 40= 150
x=150
Therefore the answer is $150
Answer:
(x - 2)^2 + (y + 5)^2 = 5
Step-by-step explanation:
If the center is at (h, k) : (2, -5), then the general form of the equation of this circle is
(x - 2)^2 + (y + 5)^2 = r^2, and we must find r^2.
We know that (3, -3) is a point on the circle. Substitute 3 for x and -3 for y in the above equation to find r^2:
(3 - 2)^2 + (-3 + 5)^2 = r^2, or
1^2 + 2^2 = r^2
Then r^2 = 5, and the desired equation is
(x - 2)^2 + (y + 5)^2 = 5 or (√5)^2
