Answer:

Step-by-step explanation:
Use the Distance Formula:
![\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = D \\ \\ \sqrt{[6 - 1]^2 + [-7 + 1]^2} = \sqrt{5^2 + [-6]^2} = \sqrt{25 + 36} = \sqrt{61} ≈ 7,810249676 ≈ 8](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Csqrt%7B%5B-x_1%20%2B%20x_2%5D%5E2%20%2B%20%5B-y_1%20%2B%20y_2%5D%5E2%7D%20%3D%20D%20%5C%5C%20%5C%5C%20%5Csqrt%7B%5B6%20-%201%5D%5E2%20%2B%20%5B-7%20%2B%201%5D%5E2%7D%20%3D%20%5Csqrt%7B5%5E2%20%2B%20%5B-6%5D%5E2%7D%20%3D%20%5Csqrt%7B25%20%2B%2036%7D%20%3D%20%5Csqrt%7B61%7D%20%E2%89%88%207%2C810249676%20%E2%89%88%208)
Since we are talking about distance, we ONLY want the NON-NEGATIVE root.

Answer: -8
Explanation:
-sqrt(64)
If 8 x 8 = 64, then the square root of 64 is 8.
Result: -8
        
             
        
        
        
30 because the angles of the triangle should be 180. Since we know one is 90 the other is 60 so 180-(90+60)=30
        
             
        
        
        
Answer: There are 6 sections of   of rope Mario can cut from the rope .
  of rope Mario can cut from the rope .
Step-by-step explanation:
Since we have given that
Length of the rope for the tent = 7 feet
As we know that 

Length of rope is used to tie a tarp on top of the tent = 34.5 inches
Remaining length of rope is given by

According to question, the remaining rope should be cut into
 
So, Number of   sections of rope Mario can cut from the rope is given by
 sections of rope Mario can cut from the rope is given by

Hence, there are 6 sections of  rope Mario can cut from the rope .
 rope Mario can cut from the rope .
