I am a second year Computer Engineering Technology student and I am think about getting work in a recording studio, what you you recommend as far as education goes? The only recoding engineering program in my city is a specialization in a music diploma. I do not necessarily want to got school for 2 years to learn music engineering. I was think about learning more about the equipment and approach the positions as some who knows a bit about the equipment and can do basic troubleshooting.

QUESTION:
You're a pilot on an aircraft carrier. You must fly to another aircraft carrier, now 1450 km at 45 degrees of your position, moving 56 km/h due east. The wind is blowing from the south at 72km/h. Calulate the heading and air speed needed to reach the carrier 2.5h after you take off....HINT: Draw a displacement vector diagram.

Here are the problems im confused with

it says to state whether the number given is a solution to the equation.




1. 14b = 56;b = 4

2. 32 = y divided by 8;y = 256

3. 52 = y divided by 6;y = 256

____________________________________________

Solve each equation. Then check each solution .
Show your work

1. 6v = 792

2. b divided by 18 = 21

3. 19m = 266

4. g divided by 52 = 18

5. z divided by 27 = 63

6. 58 = j divided by 71


WHo knows how to do this cause im confused on what to do i did the first few problems but the rest are giveing me trouble

For the life of my I cannot solve this equation I know how, but the numbers are so hard to change them to get same coefficients that I always end with with x = 2.34523 and I am fairly sure that the variables equal whole numbers because this is a word problem about price per item.

equation:

1b + 100m + 16d = 435
3b + 18 m + 45d= 435
7b + 6 m + 46d= 435

Thanks for the help...

write the prime factorization of each number. Then write it using exponents.
example- 18 2x3x3=2x3^2
i get how they got the answer but not how to find the rest.
36
40

is there a trick we aren't doing that is more simple?

How could you determine the mass of an object if you were in a space shuttle?

You do not know the density, or the mass of the object on earth.
Please help me. The sooner you answer, the more likely I will choose your answer as the best answer.

I'm aware that in the northern hemisphere, low pressure systems circulate counterclockwise and high pressure systems in the northern hemisphere circulate clockwise, etc. However, I really don't understand why this happens; my teacher claims we don't need to know why but I want to know so I can remember it easily. Any explanations?
