Step-by-step explanation:
Since she has $16 left, this means she spent $84. ($100-$16=$84)
Then, since she bought the same give for 7 of her friends, divide:
84/7=12.
This means that each gift cost $12.
20x = 2*100
x = 10 ml (amt of 30% solution needed)
100-x = 90 ml (amt of 10% solution needed)
Very hard but I hope it helps

Hello!</h2>
The answer is:
The slope of the hill is equal to 2.
<h2>Why?</h2>
To solve the problem, we need to remember that the slope of a line, is the rate of increase or decrease of the line.
From the statement we know that the tallest peak of the roller coaster is 310 feet (y), while the roller coaster travels 155 horizontal feet (x), so, calculating we have:

Then, substituting the given information and calculating, we have:

We have that the slope of the hill is equal to 2.
Have a nice day!

Answer:
723.53 m^2
Step-by-step explanation:
The area is the product of the width and length. Each foot is 0.3048 meters, so the area in square meters is ...
(59 ft·0.3048 m/ft)·(132 ft·0.3048 m/ft) ≈ 723.53 m^2
