Eggs DO sound good about now. How about some bacon?

Couldn't you just use the law of sines?

Nine to the second power (squared) is Eighty-One

10x+20y

I don't think you can, I haven't messed around with the calculator enough to see. Try asking a mod.

By putting one number over the other Numerator over denominator. On the calculator, just push the divide button.

Music anyday.

Squared simply means multiplied by itself, so 9² = 9 * 9 = 81

Let x be the unknown score.....and we have....

[ 84 + 93 + 89 + 88  + x ] / 5   = 90       multiply both sides by 5

84 + 93 + 89 + 88  + x  =  450     simplify

354 + x   = 450     subtract 354 from both sides

x = 450 - 354  

x = 96    is the lowest  score he can make to have an average of  "90"

Another way of looking at it is to consider how the scores vary from the desired mean result of 90. So we have 84 = 90 - 6, 93 = 90 + 3, 89 = 90 - 1 and 88 = 90 - 2.

So we have -6, 3, -1 and -2, which total -6. Therefore Kent needs to score 90 + 6 in the fifth test, which gives the same answer as before (96).

The first four test scores were 84, 93, 89 and 88, which total 354.

To get a mean of 90 over 5 tests requires a total score of 5 * 90 = 450.

So Kent needs to score 450 - 354 = 96 on the fifth test.

P(yellow from first bag) = 4/(7+4) = 4/11 ≈ 0.3636

P(yellow from second bag) = 3/(5+3) = 3/8 = 0.375

P(both drawn chips are yellow) = (4/11) * (3/8) = 12/88 ≈ 0.1363 recurring

Fractions (12/88) always give an exact solution, decimal representation may not, as in this case.

We  have 11 chips in the first bag and 4 are yellow......so the probability of drawing a yellow chip =   4/11

And we have 8 chips in the next bag and 3 are yelllow......so the probability  of drawing a yellow chip = 3/8

And the probability of drawing a yellow chip from the first bag and then a yellow chip from the second  bag  is given by multiplying the separate probabilities......so we have....

[4/ 11] * [3 / 8 ]   =    { swap denominators }

[4 / 8]  * [ 3/ 11]  =

[1 / 2 ] * [ 3 / 11]  =

3 / 22    = about  13.64%

It's two. I answered it anyways.

500-397= 103

The ratio between NH3 and O2 is 4:3, respectively.

So for every four NH3's you have, you gotta to have three O2's.

I dont feel like doing the conversion steps... sooooooo here:

You need 60 grams of O2 to react with 5 moles of NH3.

You start with:

(-125)^-2/3

Though this actually equals:

\(\sqrt[3]{-125}^{2}\)

Square -125:

\(\sqrt[3]{15625}\)

Find the cube root of 15625:

25

You start with:

-3v = -21

Divide by -3 on both sides:

v = 7

You're given:

x/8 - 5 = -5 

Add five to both sides:

x/8 = 0

Multiply by 8 on both sides:

x = 0

cos^-1(x/5)-sin^-1(12/13) = tan^-1(-35/56)

cos^-1 (x/5)  - 67.38°  = -44.19°      add 67.38°  to both sides

cos^-1 (x/5) =  23.19°    ...... this says that......

cos(23.19) = x/5        rearrange to solve for x

x =  5cos(23.19)  = about 4.596

9+b=14      Let's subtract '9' from each side of the equation

9-9 + b = 14 - 9  

b= 5

Substitute   5   into the equation for 'b'   9 + (5) = 14   Check!

I wish I had your work! Simply put, this is Algebra 1.

You are given:

9 + b = 14

You need to find b so in order to do that we need to make "b" be by itself, we can subtract nine on both siides of the equal side to have b on one side and the value on the other:

b = 5

You can't simplify this any further so it's the answer, In order to check, just plug in 5 where b was in the equation.

Hope this helps
