The diameter of a circle is the distance across at its widest point (right through the center). The radius is the distance from any point on the circle to the center (which means it's half of the diameter. Since we know the radius of the manhole cover is 12 inches then...
diameter = 2 × r
diameter = 2 × 12
diameter = 24 inches
I believe the answer you are looking for is the quadratic formula. because it has the formula correct, and it to me just looks exactly like it.
So, it has the ax^2+bx+c=0 but just a little difference, it has a subtracting sign instead of adding.
I don't know if I am right, but that is my guess. I remember doing those lol
12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric
she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds
each dog bed sells for 17.50.....5 * 17.50 = 87.50
87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==
Answer:
-1
Step-by-step explanation:
It's going down so it's a negative, and it's going down one square unit at a time so just 1.
