When you need to divide one fraction by another one,
here's what you do:

-- Flip the second fraction over.
-- Then multiply them.

================================

2/9  divided by  5/12  =  2/9  times  12/5

When you multiply fractions, you multiply the numerators to get the numerator,
and multiply denominators to get the denominator.

2/9  times  12/5  =  (2 times 12) / (9 times 5)  =  24/45  =  8/15
HI. So our problem is: 2/9 ÷ 5/12, lets start out with what I explained earlier in the other problem: KCF, which represents: Keep Change Flip, you can always use this for dividing, so what we do: Keep 2/9 we Change the ÷ sign to a × (multiply sign) and we Flip 5/12 to 12/5 (improper fraction)... So what is our problem now? : 
2/9*12/5= (12*2=24) (5*9=45) So what do we have? 24/45 :) And for simplest form... you can see it is not equal :) Hope that isn't too long! 

During the financial crisis of 2008, the price of a barrel of Brent crude oil fell a high of $140 per barrel to around $50 per barrel. What is the percent decrease in the price of oil that occurred during this period.

Answers

Answer:

  decrease of 64.3%

Step-by-step explanation:

Percentage change can be calculated from ...

  pct change = ((new value)/(original value) -1) × 100%

  = (50/140 -1) × 100%

  = (-9/14)×100% = -64 2/7% ≈ -64.3%

The price of crude fell about 64.3% in that period.

Slope and y intercept

Answers

The equation of a line is given by y = mx + c; where m is the slope and c is the y intercept.
The given equation is 13x - 11y = -12
11y = 13x + 12
y = 13/11 x + 12/11.
Therefore, the slope is 13/11 and the y-intercept is (0, 12/11).

The product of (3 + 2i) and a complex number is (17 + 7i). the complex number is?

Answers

Hello,

(3+2i)*x=17+7i
==>x=(17+7i)/(3+2i)
==>x=(17+7i)(3-2i)/((3+2i)(3-2i))
==>x=(65-13i)/13
==>x=5-i
