Ti-84 will not turn
TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Whats more a mg. or a ml.
Milligram is a unit of mass. Milliliter is a unit of volume. Comparing the two is like trying to compare pounds and gallons.
One ml of water will weigh 1000 mg. One ml of gold will weigh nearly 20000 mg.

How many jelly beans are in a jar thats 23 inches around and 17 inches high?
V = (pi)(r square)(h)
V= Volume (the amount we need to calculate)
pi = 3.14...
r = radius of cylinder (remember this is half that of the circumference)
h = height of cylinder
To make it easier for you below are the figures for the Cylinder.
Radius= 11.5 inches
Height = 17 inches.
Now use the formula above to calculate it.
For the Jelly Bean its,
Radius = 0.25 inches
Height = 0.5
Use the same formula above for jelly bean as well.
Once you have both figures, divide Volume of Jar by Volume of Jelly e.g. VolumeofJar/VolumeofJelly
AND VOILA, you have the amount of jelly beans in a jar (Round the figure out)
Cheers!
