A total of 600 advertisements were sold for a certain magazine. If 30 percent of the first 200 sold were in color, 20 percent of
solong [7]

Answer:

%35 of them were in color

Step-by-step explanation:

Since 30 percent of the first 200 sold were in color, 200x30/100 = 60 of them were in color.

Since 20 percent of the next 300 sold were in color, 300x20/100 = 60 of them were in color.

Since 90 percent of the last 100 sold were in color, 100x90/100 = 90 of them were in color.

In total, 60 + 60 + 90 = 210 out of 600 were in color.

The percentage is:  \frac{600}{100} = \frac{210}{x} → x = \frac{21000}{600} = 35

Pls help fast:<br>How many ways can 3 songs be chosen from 12 to create a 3 song ordered play list?​
leva [86]

Answer:

1320

Step-by-step explanation:

Total number of songs = 12

Number of songs required to arrange in a play list = 3

It means we have to arrange 3 songs from 12 in the play lines. So, required number of ways is

Ways=^{12}P_{3}

Ways=\dfrac{12!}{(12-3)!}         [\because ^nP_r=\dfrac{n!}{(n-r)!}]

Ways=\dfrac{12\times 11\times 10\times 9!}{9!}

Ways=1320

Therefore, the required number of ways is 1320.
