X = √3 * ( 1 / cos(60°) ) = 2√3
y = √3 * tan(60°) = 3
hope I helped.
What you would need to do is find out how many pages can he read in 1 hour. If he can read 20 pages in 4 hours, then that means he can read 5 pages in 1 hour. So, what you need to do is divide 5 by 200, and you'll get 40. Armando will finish the whole book in 40 hours.
Subst. the given x and y values: 6(-1)^4 * (3)^3
6 * 27 = 162
Note that you MUST do the exponentiation first.
Also note that your post would be much clearer if you'd please use " ^ " to denote exponentiation: 6x^4 * y^3
Answer:
6.625 OR 53/8
Step-by-step explanation:
hope that helps!
Profit = paid - supplies
Plug in the given values. We are finding out how much money he needs per room, if he is doing 4 rooms, and subtracting the supplies: 300 = 4n - 4*32.50
Simplify: 300 = 4n - 130
Add 130 to each side. 430 = 4n
Divide by 4 on each side: 107.50= n
300 = 4(107.50) - 130? True
This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.
