Answer:
Reference angle is 
and tan
= -1
Step-by-step explanation:
lies in the 4th quadrant
and reference angle for angle in 4th quadrant is 2π - x , where x is the angle given.
and reference angle for is
2π- =
and tan = -tan = -1

Answer: My guess is $4.55
Step-by-step explanation:
2.50 + 1.75 = 4.25 (This is the total of everything you bought)
4.25 x 0.07= 0.2975 (0.2975 is 7% of 4.25 but because this is money I will round it to <em>0.30</em>)
(0.30 is the tax so now add it to the original amount)
$4.25 + $0.30 = $4.55
For this problem, you would have to use a system of equations. Hope this helps!
Answer:
65 cups
Step-by-step explanation:
If she sold 10 more cups of lemonade than tea and sold 120 cups total. I first would subtract 10 cups from 120 =110. then I divide 110 /2 = 55 cups
The 55 cups makes it equal then I add the 10 cups back to the Lemonade to get 55+10 = 65
So your answer would be 65 cups of lemonade
