he must run 30 miles to burn 1200 calories
Step-by-step explanation:
8 miles = 320 calories
Answer:
x = 18
Step-by-step explanation:
Given ![3 \sqrt[4]{(x-2)^3}-4 = 20](https://tex.z-dn.net/?f=3%20%5Csqrt%5B4%5D%7B%28x-2%29%5E3%7D-4%20%3D%2020)
now adding '4' on both sides, we get
![3 \sqrt[4]{(x-2)^3}-4+4= 20+4](https://tex.z-dn.net/?f=3%20%5Csqrt%5B4%5D%7B%28x-2%29%5E3%7D-4%2B4%3D%2020%2B4)
![3 \sqrt[4]{(x-2)^3} = 24](https://tex.z-dn.net/?f=3%20%5Csqrt%5B4%5D%7B%28x-2%29%5E3%7D%20%3D%2024)
i)
= <u>24</u>
cancelling '3' on both sides, we get
![\sqrt[4]{(x-2)^3} = 8](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%28x-2%29%5E3%7D%20%3D%208)
ii)
= <u> 8</u>
<u>iii) </u>
<u></u>
<u></u>
<u></u>
iv) 
now simplify on both sides,we get


simplify we get solution is
<u>v) (x-2) </u>= 16
<u>vi) final answer is x = 16 +2 =18</u>

The only statements that is true about the information on the table are:
- The ratio of students who wish they had flight to those who wish for invisibility -Ratio 2:3. All other statements/ratios are false/incorrect.
<h3>
How do we get the ratio of students who wish they had flight to those who wish for invisibility?</h3>
Ratio is simple math.
The number of people who wish for invisibility are: 12 ; while
The number of people who wish for flight are: 8
Thus the ratio will be given as:
8/12 further simplified by dividing by 4, we have
(8/4) : (12/4)
= 2:3
Hence, only the last statement is true.
