Sam is an accountant. he finds that he spends two-fifths of his work day answering emails. if he kept 3.6 hours answering emails yesterday, how many hours did he work?

Let the total hours that Sam has in a workday be depicted by the letter x.

Sam finds that he spends two-fifths of his work day answering emails which amounts to 3.6 hours.

If we write the above information mathematically, we will get:

We will now isolate x. Thus we have:

hours

Thus Sam has a typical workday of 9 hours. Out of this he spends 3.6 hours writing emails. Therefore, the number of hours Sam worked is:

9-3.6= 5.4 hours.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

darn right!
