There will only be one solution to this problem.
220 = 2x - 12x
Combine like terms on the right side of the equation:
220 = - 10x
Divide both sides by - 10 to isolate the variable x.
220 / - 10 = x
-22 = x, one solution.
1) circumference of the first bead = 0.25 in
2) circumference of the second bead = (0.25 + 0.15) in
3) circumference of the third bead = 0.25 + 0.15*2 in
4) circumference of the nth bead = 0.25 + 0.15 * (n -1) in
5) circumference of the 24th bead = 0.25 + 0.15 * (24 - 1) = 3.7 in
6) circumference = 2π*radius => radius = circumference / (2π)
7) radius of the 24th bead = circumference of the 24th bead / (2π)
radius of the 24th bead = 3.7 inches / (2π) = 0.5889 in ≈ 0.59 in
Answer: 0.59 in

Answer:
Step-by-step explanation:
To find the time at which both balls are at the same height, set the equations equal to each other then solve for t.
h = -16t^2 + 56t
h = -16t^2 + 156t - 248
-16t^2 + 56t = -16t^2 + 156t - 248
You can cancel out the -16t^2's to get
56t = 156t - 248
=> 0 = 100t - 248
=> 248 = 100t
=> 2.48 = t
Using this time value, plug into either equation to find the height.
h = 16(2.48)^2 + 56(2.48)
Final answer:
h = 40.4736
Answer:
x = 32
Step-by-step explanation:
x/4 = 8
<=> x = 8 . 4
<=> x = 32
