I substituted in a 6th grade class today and we did a worksheet of these brainteasers. We came up with 32 Teeth in an Adult.
It is 32t^5.
32 teeth for an adult human
t - 2t - 3t = 32t - 5t = 32-4t = 32t = -8According to the information given in the question, t can't equal 8.
You need t to find the value.

Negative sixteen plus thirty two is 16. When a number is negative, subtract the negative number from the positive one to find the answer.
The problem can be solved using calculus. We want to obtain the maximum of the function h = h(t). First, we derive h with respect to t, dh/dt = - 2(16)t + 48 = 48 - 32t We then equate to zero and solve for t, 48 - 32t = 0 t = 48/32 = 1.5 So, the maximum altitude for the ball is acquire at t = 1.5 seconds. And the height is, h = 48(1.5) - 16(1.5) * 2 = 36 ft

if you are looking for a 25t sprocket then you need a 9t rear driver other wise it going to feel like you a pedaling forever and not going anywhere there are websites or just look online for proper bmx gearing ratio's also you may need spacers for your cranks
14°C is about 57.2°FStart by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about 57.2 degrees Fahrenheit.57.2 F
5 in Fahrenheit is -15 in Celsius. To convert Fahrenheit temperatures to Celsius, subtract 32 from the degrees Fahrenheit, and then divide by 1.8. For example, 5 degrees minus 32 equals minus 27 (or -27). Then divide by 1.8 and you get minus 15, or (-15) degrees Celsius.
That's like asking if a size 10 shoe is better than a size 11. You need one that fits, that's all, what size it is isn't that important. I'm assuming here that you are talking about a BMX, and the sprocket by the pedals, and that you're planning to keep the "driver"/rear sprocket. If you feel that you're too slow off the start, then going from 32T to 25T will make you quicker to get going. The downside is that with the 25T you will lose a bit of top speed on account of not being able to spin the pedals any faster. If you think you'rfe doing OK from standstill, then replacing the sprocket will make you slower w/o anything good to trade for it.
