In order for them to work the same amount of time, you would have to make Lucas work for five hours (so he could have the same minimum time as Jonathan). So multiply Lucas's 30 minutes by five, and that equals a total of 2 hours and 30 minutes. So when Jonathan works for five hours he plays for three hours, but when Lucas works for 5 hours he only plays for 2 hours and 30 minutes. So Jonathan spends more time playing video games.
Answer: equation = $600 + tx$8 = $640 ; t = 5 additional hours in May
Step-by-step explanation:
Equation = $600 + tx$8/hour = $640
t = ($640 - $600)/$8/hour
t = $40/$8/hour = 5 hours
Answer: Equation = $600 + tx$8 = $640 ; t = 5 additional hours in May

Answer:
2√5
cos x = -------------

Step-by-step explanation:
If tan x = 1/2 then what is cos x?
Recall that tan x is defined as the quotient sin x / cos x, so that in this case sin x / cos x = 1 / 2 = opp side / adjacent side. Also, recall that cos x = adj side / hypotenuse.
To determine cos x, we need to find the length of the hypotenuse. That, in turn, through use of the Pythagorean Theorem, is √(1^2+2^2), or √5.
Then cos x = adj side / hyp = 2/√5. Rationalizing the denominator, we get
2√5
cos x = -------------
