Answer:
18 cups.
Step-by-step explanation:
We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation:
.
To find number of cups x to make a profit of at least $20 we will use our given inequality.






Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.
Answer:
1. Yes it does. It's a function because it pass in the vertical line test, which tell us that if you can draw an vertical line through the graph and this line touches the graph in only one point, it is a function.
2. B. I and II only
3. A. y = 8/7 x +5
Answer:
R = -8 1/6
Step-by-step explanation:
We'll solve the given equation for R.
Subtract 3 1/2 from both sides of the equation, to isolate R:
R + 3 1/2 - 3 1/2 = -4 2/3 - 3 1/2, or
R = -4 2/3 - 3 1/2
The LCD here is 6, which is the product of 3 and 2. Converting the fractions to denominator 6, we get:
R = -4 4/6 - 3 3/6, or
R = -7 - 7/6, or R = -7 - 1 1/6, or -8 1/6
Answer:
100.48 feet
Step-by-step explanation:
The circumfrence of a circle is represented in the equation C=2\pi r^{2}
So we input the values into the equation C=2(3.14)(4)^2 which when entered into a calculator gives you 100.48feet
