The ratio of men to women in a certain factory is 3 to 4. There are 222 men. How many workers are there?
IgorLugansk [536]
The ratio of men to women in a certain factory = 3:4
The total number of men in the factory = 222
Let us assume the common ratio to be = x
Then
3x = 222
x = 222/3
  = 74
Then
The total number of women workers in the factory = 4 * 74
                                                                                 = 296
So
The total number of workers in the factory = 296 + 222
                                                                    = 518
From the above deduction we can easily conclude that there are a total of 518 workers in the factory.

5. Suppose a password requires three distinct letters. Find the number of permutations for the three letters in the code if the
Roman55 [17]

Answer:

There are 15600 ways to pick a password

Step-by-step explanation:

We have 26 possibilities to pick a letter. So, we have 26 possibilities for the first component of the password. The second letter should be different from the first one, so we have one less possibility, giving us a total of 25, and for the third letter we have 24.

This gives us 26*25*24 = 15600 ways of picking a password.

What is the surface area of the square pyramid?<br> (Figure is not drawn to scale.)
Reil [10]
Area of the base = 8^2 = 64

area of 1 traingle = 1/2 * 8 * 5.4 =  21.6

there are 4 triangular sides  so their area = 4 * 21.6  = 86.4

Total surface area = 64 + 86.4 =  150.4 cm2
