A shortage of gold causes the price of gold wire to increase by 140%. If 10 feet of gold wire previously cost $50, what is the n
Marianna [84]
The increase in price is 140% of the original price.
The original price was 100% of the original price since 100% is a whole quantity.
Now the new price is 140% more than it was, so the new price is
100% + 140% of the old price.
100% + 140% = 240%

Now we find 240% of $50.
To find a percent of a number, multiply the percent by the number.

240% of $50 =
= 240% * $50
= 2.4 * $50
= $120

Answer: 10 ft of gold wire now costs $120
Gold wire now costs $12 per foot.

HELP COLLEGE ALGEBRA
max2010maxim [7]

Answer:

1) \frac{-8}{11}  

2) 1.276

3) \frac{3}{4}

4) 0

Step-by-step explanation:

The slope formula of the line that pass across two points P1(x1,y1) and P2(x2,y2) is:

\frac{y2 - y1}{x2-x1} = slope

You can use this formula to solve all the four points:

1)

\frac{6- -2}{-9 - 2} = \frac{-8}{11}

2)

\frac{- 9.1 - 0.6}{-9.5 - - 1.9} = \frac{97}{76} =(Rounded)= 1.276

3)

\frac{2-5}{-2 -2} = \frac{3}{4}

4)

\frac{4-4}{-9 --4} = \frac{0}{-5} = 0 \\\\

What is the third quartile of the following data set<br><br> 24,20,35,39,28,42,25,29,44,21,37
strojnjashka [21]
First, arrange the data:

20, 21, 24, 25, 28, 29, 35, 37, 39, 42, 44

You can use the formula 
3/4 multiplied by the number of data + 1 to find the position of the 3rd quartile.

so it's going to be 3/4 x (11+1) = 9th position

the number in 9th position is 39 so that's the 3rd quartile
