Answer:
4 mi/h
Step-by-step explanation:
The distance between the cyclists is the hypotenuse of an isosceles right triangle. The hypotenuse is √2 times the length of the legs in such a triangle, so each cyclist must have ridden 8 miles in 2 hours.
Their speed is (8 mi)/(2 h) = 4 mi/h.

<em>Additional comment</em>
Consider an isosceles right triangle with leg lengths 1. Then the Pythagorean theorem tells us the length of the hypotenuse is ...
c² = a² +b² . . . square of hypotenuse is sum of squares of legs
c² = 1² +1² . . . . both legs are 1 in our example triangle
c² = 2
c = √2
That is, the hypotenuse is √2 times the leg length.
Answer:
(7, 3)
Step-by-step explanation:
(2+5, 6-3) = (7, 3)
Semi-monthly means twice every month, typically either on the 1st and 15th,
or on the 15th and last.
Months don't line up with weeks in any regular way. Depending on the
company, if they say "bi-monthly", they may pay 24 times a year, or else
26 times a year.
If they pay every 2 weeks, the semi-monthly is $2400.
