Let the angle of elevation be θ.
We have a right angled triangle with an opposite of 300.5 ft. (306 - 5.5) and an adjacent of 400 ft. Recalling SOH CAH TOA, tanθ = O/A.
tan(θ) = 300.5/400.
θ = tan^-1(300.5/400).
θ = 36.9°.
<span>You are given
John Davis’ rate which is $9.75 an hour. It is said that he works for four
hours on Monday, six hours on Tuesday, five hours on Wednesday, five hours on
Thursday, and seven hours on Friday. You are asked to find the gross pay of John
Davis. All you need to do is to multiply the rate to the hour of work.</span>
<span>
Monday: $9.75(4h)
= $39</span>
Tuesday:
$9.75(6h) = $58.5
Wednesday:
$9.75(5h) = $48.75
Thursday:
$9.75(5h) = $48.75
Friday:
$9.75(7h) = $68.25
<span>
To get the
gross pay, add everything and you will get $263.25. The answer is letter D.</span>
I think it is reasonable. She will have extra cash (almost $500) but that isn't a bad thing when you are going on a vacation.
If you need to know how to do it, what I did was take the $48 and the 52 weeks and multiply them together to get $2,496.... But if you think in your own opinion it's not reasonable than say she could trim down her savings and only try to earn about 40 dollars each week; you get to the closer amount of $2,000 with $2,080...
I hope this helps. Choose for yourself though! <3 Good luck! (:
