I need help on these 3 Hardy Weinberg Problem..can someone go through the steps of each one to show how you got the answer? I'm totally confused!

4. A population of mice shows a recessive trait of white fur 49% of the time. What is the frequency of the dominant allele?

5. In a midwest town with a population of 9375, 75% of the townsfolk show the dominant trait of free earlobes. How many people in this should be heterozygous for free earlobes?

7. the frequency of stillbirths homozygous for a recessive lethal gene is about 1 in 25000. What is the proportion of the carriers (heterozygous) in that population?

We all know that actually compass needle points to the north pole. But does it work when we Are in the north pole? Where should it point anyway.

I have this question on my homework:

4x^2 + 20x - 4y^2 + 6y - 3 = 0

I think that this is a hyperbola (I thought it was a circle..but the 4y^2 is negative so I guess it's a hyperbola). Can you convert it to graphing form? I got an answer but there's a bunch of fractions in it and I have no idea if it's right or not. Thanks.

There are three that I am disputing. Here they are:

Determine the number of atoms that are in 1.25 mol of O2.

Find the percentage composition of a compound containing 32.0 g of bromine and 4.9 g of magnesium.

If your chemistry classroom has a volume of 1.8 x 10^5 dm^3, how many gas particles are in the room at standard temperature and pressure? (Remember that 1 mole of any gas occupies 22.4 dm^3 at STP.)

Thank you for your help!

I have a physics question:
Two astronauts outside a space capsule decided to play catch with a third astronaut. All the astronauts weigh the same on earth and are equally strong. The first astronaut throws the second toward the third and the game begins. Describe the motion of the astronauts as the game proceeds. How long will the game last?

I have to explain this question using momentum. Please help!!!

Jennifer is considering a strategy for an upcoming 2-mile bicycle race. During practice she maintains a speed of 20 miles per hour for the first mile, but fatigue reduces her speed to 10 miles per hour for the second mile.

Explain why Jennifer's average speed over these 2 miles is not the same as tha arithmetic mean of 20 miles per hour and 10 miles per hour. Find Jennifer's average speed for these 2 miles.
