The ratio of males to females was 4:5. If there are 180 people at the fair how many males are there?

9514 1404 393

  80

Step-by-step explanation:

Let m represent the number of males. Then you have ...

  m/(180 -m) = 4/5

  5m = 4(180 -m) . . . . cross multiply

  9m = 720 . . . . . . . . add 4m, simplify

  m = 80 . . . . . . . . . . divide by 9

The number of males at the fair was 80.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
