8 days
Step-by-step explanation:


It takes Time 8 days to clear 1 acre
2 1/2 because 50-20 leaves you with 30 so you have one. Than 30-20 leaves you with 10. Now you have two. There isn't another 20 but 10 is half of twenty so that gives you a half so it is 2 1/2
First find out the triangle (red) in the top left.

The area of a triangle is found by length times width and divide it all by 2 because a triangle is half of a square. Now we multiply that by 2 for the second triangle (in green) at the bottom. We can do this because the blue does to the half way mark on the quilt so the other triangle on the bottom has to be the same.

Now we find out the area of the whole SQUARE quilt. It already gave the measurement of one side so they all have to be the same.

Now we only need the area of the side the blue is on. So divide by 2 and get 72.
Now subtract 18 from 72.
The answer is 54 for blue.
B.) We say that there is a positive correlation between x and y if the x-values increase as the corresponding y-values increase
Answer:
-4.5
Step-by-step explanation:
(y2-y1)/(x2-x1)
(8+10)/(-5+1)
(18/-4)
-4.5
