Kate is allowed to work no more than 20 hours a week. she has already worked 13 hours this week. at most, how many more hours can she work? write and inequality and solve.

h ≤ 7

h stands for hours. We use the less than or equal to symbol, since she can work 20 hours, but nothing above that, and she can also work less than 7 hours.

tan47=1.0724

cos60=0.5

-btw next time you can use a calculator instead of wasting points, all you need to do is type in the numbers in a sientific calculator, press tan and then type in 47 and hit enter and then you should get it :(
