28 divided by 8 is equal to 3.5, so one hotdog will cost $3.50
Hi Friend
Here is your answer
The volume V of a circular cylinder is given by
V=13πr2h cubic centimeters
where r is the radius in centimeters and h is the height in centimeters. Substitute V=255 and r=6 and solve for h.
Let me now if it is right.
Answer: b/a = -8
Step-by-step explanation:
When we have a quadratic equation:
y = a*x^2 + b*x + c.
The vertex of this function (and the axis of symetry) is located at:
x = -b/2a
Now, we know that the axis of symmetry is at x = 4.
then we have:
4 = -b/2a
And we want to find b/a.
Then we start with:
-b/2a = 4.
first we multiply by 2 in each side:
2*(-b/2a) = -b/a = 2*4 = 8.
now we multiply by -1 in each side:
-1*(-b/a) = b/a = -1*8.
Then we have: b/a = -8
20. Since PQS = 112, RQS = 112 - 72 = 40
So now we know 10X = 40
Divide both sides by 10: X = 40/10 = 4.
21. 16Y = 135 - 47
16y = 88
y = 88 / 16
y = 5.5
It would equal 3
i hope this helps
