4.2 is also equal to 42/10 which is equal to 21/5. In order to find how many trips you will be dividing fractions (21/5) / (3/5). Although this may seems difficult, because the denominators are the same, it simplifies to 21/3 which is equal to 7 (A)

HACTEHA [7]

Answer:

5.83095 or √34

Step-by-step explanation:

Find the difference between coordinates:

(x2-x1) = (-1 - -4) = 3

(y2-y1) = (-10 - -5) = -5

Square the results and sum them up:

(3)2 + (-5)2 = 9 + 25 = 34

Now Find the square root and that's your result:

Exact solution: √34 = √34

Approximate solution: 5.831
