Answer:
Your bicycle has 22 gears.
Step-by-step explanation:
The number of gears in the bycicle is the number of combinatiors of a front sprocket and a rear sprocket.
For each front sprocket, there are 11 rear sprockets. There are 2 front sprocts.
So, the number of gears that your bicycle has is
2*11 = 22.
Answer:
Part 1) The volume of each beam is 
Part 2) You can fill 
Part 3) Yes, the amount of sand left over is 
Step-by-step explanation:
Part 1) What is the total volume of each beam?
The volume of a cylinder is equal to
we have
----> the radius is half the diameter
assume
substitute the values
Part 2) How many beams can you fill with this sand?
we know that
You are given a container with a 50,000 sq ft of sand for your beams
<em>Note</em> Is a 50,000 cubic foot of sand instead of 50,000 sq ft of sand
Divide the total volume of sand by the volume of each beam to obtain the number of beams
Round down
Part 3) Will you have any sand left over? If so how much?
yes
Answer:
The answer is 10
Step-by-step explanation:
Answer:
Step-by-step explanation:
“the center of the ellipse is located below the given co-vertex”
Co-vertex and center are vertically aligned, so the ellipse is horizontal.
Equation for horizontal ellipse:
(x-h)²/a² + (y-k)²/b² = 1
with
a² ≥ b²
center (h,k)
vertices (h±a, k)
co-vertices (h, k±b)
foci (h±c,k), c² = a² -b²
One co-vertex is (-8,9), so h = -8.
One focus is (4,4), so k = 4.
Center (h,k) = (-8,4)
c = distance between center and focus = |-8 - 4| = 12
b = |9-k| = 5
a² = c² + b² = 169
(x+8)²/169 + (y-4)²/25 = 1
No.2 and that last no. is true statement.
