# I Need Help Can You Help Me

Can you help me with my math HW? I need the formula, how to do the problem, as well as the answer?

Here's the problem:

Gear A: 15 teeth
Gear B: 18 teeth
Gear C: 24 teeth

Gears are aligned and each gear has the number of teeth indicated. What is the least positive number of rotations gear C must make before the arrows will be aligned the same way?

I seriously need help. can you help me?

can you answer these questions for me? thank you. p.s. answer the ones you know=]

1.describe how amplitude,frequency and wavelength are determined in transverse/compressional waves.

2.a bus driver is rounding a curve approaching a railroad crossing. she hears a train's whistle and hears the whistle's pitch become lower. what assumption can she make about what she will see when she rounds the curve and looks at the crossing?

3. when a boy blows a dog whistle the dog came, but the boy can't hear the whistle, why?

4.why does the ringing of an alarm clock enclosed in an airtight container become softer as the air is drawn out of the container?

5. explain how sound waves are converted to radio waves? examples please.

6. how is the reflection of light off a white wall similar to the reflection of light off a mirror? how is it different

I need help with a math problem, can you help me?

P= 2W + 2L [Perimeter= 2 times width plus 2 times height]
P= 2(4.2) + 2(3.65) [= 2 times 4.2 plus 2 times 3.65]
P= 8.4 + 7.3 [= 8.4 + 7.3]
P= 15.7 inches squared

Perimeter= 15.7 square inches, or 15.7 inches squared.

I need help with my math, can you help me?

1. if you know that the hypotenuse is 13 and one leg is 5 you can set up this equation
5^2 + x^2= 13^2
x^2=144
x=12
So 1/2x5x12= 30
2. first, let's find the average o f 18 and 42.
18+42= 60/2 = 30
30x4/5 = 24
3.A percent is the # of ppl who are left handed/ everyone in the class
6/24=1/4=25%
4. you have to work backwards on this one. so 20% of 80% is
the same as 1/5x4/5=4/25 or 32% 15% of that can be written as
3/20 x 4/25 = 12/500 = 3/125 = 2.4%

BTW, some of the people above me don't know how to divide, add, etc. So if you want the right answer, it would behoove you to listen to me.

Can you help me with my homework?

I need help with this physics homework. The question is:

A flywheel is rotating at a high speed. No energy is being supplied to it. The flywheel is used to turn a dynamo, and the energy from the dynamo is used to light a bulb.
The experiment is repeated using a different bulb which gives out more energy each second. Compared to the first light bulb describe how the second light bulb will affect the motion of the flywheel and explain your answer.
