Answer:
50
Step-by-step explanation:
The distance between the friends is changing at the constant rate of 50 mph.
___
The equation for the distance in the westerly direction is ...
w = 30t . . . . . miles, where t is time in hours
The equation for the distance in the southerly direction is ...
s = 40t . . . . . miles, where t is time in hours
Then the total distance between the friends is ...
d = √((30t)² + (40t)²) = √(2500t²) = 50t . . . . miles, where t is time in hours
And the rate of change of distance is the derivative of this with respect to t:
dd/dt = 50 . . . . . . miles per hour
Answer. To verify that the decimals are lined up correctly, we must ensure that they are both lined up at the same point. The reason this is done is so that whole numbers will be subtracted from other whole numbers, not decimals.

Answer: 31 hope this helped
Step-by-step explanation: I'm assuming your problem looks like this: 4+5*6-3 =? To solve this problem you need to use the order of operations. PEMDAS which stands for Parentheses, exponents, multiply and divide, and lastly add and subtract. You must multiply and divide before you add and subtract so you must do 5*6 first. You now get 4+30-3. Now all you have left is addition and subtraction so you now just go from right to left and do one at a time. So 4+30 = 34 , 34-3=31. Therefore your answer should be 31. Hope that helped!
