I have a solution of methyl red which is 3.27x 10^ -4 M that is prepared by diluting 10 mL to 100mL. What is the concentration?

Is doing (3.27x10^-4)(.01)= x(.1) to solve for the concentration the right way?
= 3.27x10^-5

Thanks in advance!

A hand grenade is thrown at an angle of 35 degrees from the horizontal at a speed of 58 miles/hour. 1.6 seconds after it is launched, it blows up.

1. How high above the ground is it? (ft)
2. How far is it from the thrower?

My answers come out to:

1. 39 ft
2. 111.5 ft

I'm fairly certain about the second one, but I'm not sure about the first answer. Help?

Thanks.

plants are animals are both formed living cells .... when the first cell was formed in the world it multiplied started joining together .... some cells became plants so that they can be eaten ........some cells become trees which produced fruits ..... some cells become animals ... some cells birds ....
what i wonder is evolution theory states that living beings are evolved as per their surroundings by improving each traits by millions of years ..... then how come all different species a tree a shrub a deer and a lion grows in a same habitat ....shouldn't be it only lion ....why life evolved like something can be eaten ,,,,some thing to eat etc ............

Of the 6 courses offered by the music department at her college, Kay must choose exactly 4 of them. How many different combinations of 4 courses are possible for Kay if there are no restrictions on which 4 courses she can choose?

Please explain step by step. I'm just setting foot into this area of mathematics. I understand that the number of possible permutations are

6*5*4*3 = 360.

I want to know the way to find the different combinations including repeats.

Like...

A B C D = 1
A B D C = 2
.... = 3


... = blah?

What's the mathematical way to find the number of those?

If there were two choices the number of combinations would be

A B = 1
B A = 2
