Length - a
Width - b
Area = a * b 
320 = a & b 
b = 4/5a
320 = a^2 /5
400 = a^2
a = \sqrt{400}
a = 20
b = 16

scoray [572]
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!

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
DedPeter [7]

Answer:

C

Step-by-step explanation:

Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is y + 5.

Moving left or right affects the "x" coordinate and moving left is negative so

x - 3

(x - 3, y + 5)

 Hence, C is the correct answer
