ANSWER
C. 35 men
EXPLANATION
Let m represent the number of men needed and d represent the number of days.
From the question,the number of men needed varies inversely to the time needed to complete the project.
We can write the inverse variation equation.

where k is the constant of variation.
When m=28, d =90.
We substitute these values into the variation equation to determine the value of k.



Now the equation becomes:

When d=72,


Therefore he needs to have 35 men working.
M=-2+-4
———=2/1=1
4 + -3
(4,3 ), (-2,-4)
(X1,y1)(x2,y2)
Answer:
Step-by-step explanation:
Given
- 3 rectangular cards
- each card is 8 inches by 9 inches
The way that she can arrange the cards, without overlapping, to make one larger polygon with the smallest possible perimeter is that:
Put 3 cards together according to the length
So the smallest possible perimeter is:
8 + 8 + 8 + 8 + 8 + 8 + 9 + 9 = 66 inches as you can see in the attached photo.
The area of the polygon is equal to the combined area of the 3 cards without overlapping or extending.
Hope it can find you well.
