Both of the Students are correct, where the units are the same in the beginning and at the end. If you divide 20 feet by 4, you get 5 feet or 60 inches. If you convert 20 feet to inches, you get 240 inches. When you divide 240 by 4, you get 60 inches. Therefore, they both are correct.
Answer:
![-4](https://tex.z-dn.net/?f=-4)
Step-by-step explanation:
Step 1: Apply the rule
![\left(-64\right)=-64\\\\=\sqrt[3]{-64}](https://tex.z-dn.net/?f=%5Cleft%28-64%5Cright%29%3D-64%5C%5C%5C%5C%3D%5Csqrt%5B3%5D%7B-64%7D)
Step 2: Apply the radical rule
![\sqrt[3]{-64}=-\sqrt[3]{64}\\\\=-\sqrt[3]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-64%7D%3D-%5Csqrt%5B3%5D%7B64%7D%5C%5C%5C%5C%3D-%5Csqrt%5B3%5D%7B64%7D)
Step 3: Factor the number
![\:64=4^3\\\\=-\sqrt[3]{4^3}](https://tex.z-dn.net/?f=%5C%3A64%3D4%5E3%5C%5C%5C%5C%3D-%5Csqrt%5B3%5D%7B4%5E3%7D)
Step 4: Apply the radical rule
![\sqrt[3]{4^3}=4\\\\=-4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4%5E3%7D%3D4%5C%5C%5C%5C%3D-4)
Therefore, ![\:\sqrt[3]{\left(\:-\:64\right)}\:=\:-4](https://tex.z-dn.net/?f=%5C%3A%5Csqrt%5B3%5D%7B%5Cleft%28%5C%3A-%5C%3A64%5Cright%29%7D%5C%3A%3D%5C%3A-4)
100-75=25
27 divided by 0.25 is108
there are 108 questions on the test
I really don’t remember how to do these
