In a library where the ratio of men to women is 3 to 1, of the members are men.
3
1/3
3/4
4

Option C.

Step-by-step explanation:

Let the total number of men in the library is x and total number of women is y.

As per statement, " ratio of men to women is 3 : 1"

That means

or x = 3y

Now we add 3x on both the sides of the equation

x + 3x = 3y + 3x

4x = 3(x + y)

x =

  =

Therefore, of the members are men.

Option C will be the answer.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
