kiruha [24]

This problem is better understood with a given figure. Assuming that the flight is in a perfect northwest direction such that the angle is 45°, therefore I believe I have the correct figure to simulate the situation (see attached).

 

Now we are asked to find for the value of the hypotenuse (flight speed) given the angle and the side opposite to the angle. In this case, we use the sin function:

sin θ = opposite side / hypotenuse

sin 45 = 68 miles per hr / flight

flight = 68 miles per hr / sin 45

<span>flight = 96.17 miles per hr</span>

If it takes 1/2 day to write a report, how much will be completed after 1/4 of a day?
lana [24]

Answer:

You have completed only half in a 1/4 of a day

Step-by-step explanation:

think of it this way

lets say in half a day e.g at 12pm you finish the report

half of 12 is 6

so that would be a 1/4 of the day

100%=24 hours=whole day

50%=12 hours=half a day

25%=6 hours = quarter of a day

25% = 1/4

i hope this helps
