The answer is B. Surviving droughts
Step-by-step explanation:
Judging from the high of 400, her day 21 appears to be approx 300
if she put in 100 then the next five days she added a total of 200 more to reach 300
200/5 = $40 / day
In this problem you will need to use the Pythagorean theorem (c^2=a^2+b^2).
The a and b represents the two edges, while c is the diagonal side and it is called the hypotenuse. Since you already know what the hypotenuse is and what one of the sides already are you just have to use the problem: c^2-a^2=b^2. Then if you plug the data you already have into the problem you will get 10^2-6^2=b^2. That then equals 100-36=b^2. Then you subtract and get b^2=64. Then you square root both sides and you get the answer b=8.
