Complete Question
We have two stacks of styrofoam cups. One stack has 6 cups, and its height is 15 cm. The other stack has 12 cups, and its height is 23 cm. How many cups are needed for a stack with a height of 50 cm
Answer:
37.5 cups
Step-by-step explanation:
Height 1 = 15cm
Number of cups = 6
Height 2 = 23 cm
Number of cups = 12
Hence:
H1 - H2/N1 - N2
= 15 - 23/6 - 12
= -8/-6
= 4/3
The number of cups that are needed for a stack with a height of 50 cm is calculated as:
50 cm ÷ 4/3
= 50 × 3/4
= 37.5 cups
18² - 4 * 3 * 7 =240
x1 = (-b-root of 240)/2a = ............
x2 =(-b + root of 240)/2a = ........
