Invers proportion it takes 12 workers 3 weeks to complete four project. each project take same numbers of hours

a) at this rate how long would it take fifteen workers to complete ten project? = 6 weeks

b) the ten projects need to be completed in under four weeks. what is the minimum number of workers be needed, given that they all work at the same rate as the original workers ? ( i know answer i need axplaning ) :]

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

you can use a^2+ b^2=c^2
