A company can send a maximum of 40 workers to complete a
rewona [7]

Answer:

20

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

lesya [120]

Answer:

See below

Step-by-step explanation:

The initial ordered-pairs are (x, y)

We have a rotation of 90 degrees counterclockwise with respect to origin

Note. Previously the points were

A(-3, 4), B(-3, 0), C(-1, 3)

After the rotation, we have

A(-4, -3), B(0, -3), C(-3, -1)

Thus, (x, y) \rightarrow (-y, x)

Then shifting horizontally to the right 2 units, we get ΔA'B'C'

Thus,

(x, y) \rightarrow (-y, x) \rightarrow (x+2, y)

<span>So, they are looking for the percentage that is NOT explained... Well, given the r we can find the percentage that IS explained by it first. That's given by r^2.

</span>Now - let's take the square of r it gives me .481636. That means that about 48% IS explained. Therefore, the part that cannot be explained must be the missing part (out of 100% <span>so 100% - 48.1636% should be it :)
</span>
<span>So 100% - 48.1636% = 0.518364 and we want to round that off to three decimal places which will give us 0.518... and then we could convert that to a percent for the final. So 0.518 as a percentage is 51.8%! s</span>
