a fifth grade class sold 25 liters of orange juice the orange juice was sold in cups containing 200 millilters and 300 milliliters an equal number of cups contaning 200 milliliters and 300 millilters were sold how many cups of orange juice did the class sell
number of 200 ml cups -- x
number of 300 ml cups -- x (it said their number was equal)
200x + 300x = 25000
500x = 25000
x = 50
So they used 50 cups of each
check:
50(200) = 10000 ml
50(300) = 15000 ml for a total of 25000 ml or 25 litres
100
Mikhail used 220 inches of wire to make this figure. The figure is made up of two identical triangles, a 15 inch by 12 inch rectangle and a square of side 19 inches. What is the length of one side of each triangle if all the sides of the triangles are equal in length?
To find the number of cups of orange juice the fifth-grade class sold, we need to determine how many cups were sold for each cup size (200 milliliters and 300 milliliters) and then find the total.
Let's start by calculating the number of cups sold for 200 milliliters:
- 1 liter is equal to 1000 milliliters, so 25 liters of orange juice is 25 x 1000 = 25000 milliliters.
- Each cup contains 200 milliliters, so the number of cups sold for 200 milliliters is 25000 / 200 = 125 cups.
Next, let's calculate the number of cups sold for 300 milliliters:
- Similarly, the total amount of orange juice in milliliters is 25000.
- Since each cup contains 300 milliliters, the number of cups sold for 300 milliliters is 25000 / 300 = 83.33 cups.
Now, since the question states that an equal number of cups of 200 milliliters and 300 milliliters were sold, we need to consider the lowest whole number of cups we can have for both sizes. In this case, we can only have 83 cups for both sizes.
Finally, to find the total number of cups sold, we add the number of cups sold for each size:
125 cups (200 milliliters) + 83 cups (300 milliliters) = 208 cups
Therefore, the fifth-grade class sold a total of 208 cups of orange juice.
