Your answer is 20 vegetable plants. To answer this, you just need to find 40% of 50, as 40% of their total plants are vegetables. You can do this by dividing 50 by 10 to get 5, which is 10%, and then multiplying 5 by 4 to get 20, which is 40%.
I hope this helps!
Answer:
70%
Step-by-step explanation:
Okay, here we have this:
Considering the provided angle, we are going to calculate the requested cosine, so we obtain the following:
Then to obtain the cosine we will review the following image of the unit triangle:
So since pi radians is equal to 180°, we can see in the image that the cosine of 180 degrees is equal to -1, so we finally get that the cosine of the angle is -1.
