A company can send a maximum of 40 workers to complete a

rewona [7]

Answer:

Step-by-step explanation:

For the sake of the problem, let's make female workers "x" and male workers "y".

x+y<40 This equation shows that the total number of workers has a max of 40.

30x+20y<1,000 This equation shows that the total cost the manager pays ($30 to each woman, $20 to each man) has a max of $1,000.

Now you can solve for x and y.

X+y<40

-y -y

X<-y+40

Substitute -y+40 in for X in the second equation

30(-y+40)+20y<1,000

-30y+1200+20y<1,000 Distribute

-10y+1,200<1,000 Combine like terms

-10y<-200 Subtract 1,200

y>20 Divide by -10; flip the sign

Since y>20, and y=male workers, you now know that the minimum

number of male workers he should send is 20

Can someone help out? or explain?

Y = 90 degrees

1) The angles on a straight line add to 180 degrees so 180-110= 70 degrees.

2) The angles in a triangle add to 180 degrees so 70+70= 140 degrees. The angle at the top of the triangle will have to be 40 degrees as 140+40= 180 degrees.

3) As x is half the angle at the top of the triangle (40 degrees), x will equal 20 degrees.

4) As the angles in a triangle add to 180 degrees 20+70=90 degrees 180-90=90 degrees.

5) Answer = 90 degrees
