Every time Martina orders Chinese food, she gets egg drop soup. So, she decides to learn how to make it herself. Her recipe call
MrRa [10]

Answer:

2 cartons

Step-by-step explanation:

Hey! To start, we need to determine what we already know, Martine needs 8 cups worth of broth, but can only find 32-fluid ounce cartons.

Next, we need to find what we need to know, how many fluid ounces are in a cup? <em>There are 8 fluid ounces in 1 cup!</em>

Now, all we need to do is convert our cups to be able to find out how many cartons we need! So, to do this, we are going to multiply our number of cups by the number of fluid ounces in just 1 cup (so 8!).

<em>8 cups x 8 fluid ounces (per 1 cup) = 64 fluid ounces</em>

So! Martina needs 64 fluid ounces of broth to be able to create her recipe!

<em>But, we aren't finished just yet, as we need to find how many cartons Martina needs! Like we did before, we know that there a 32 fluid ounces in 1 carton so if we have 64 fluid ounces in the recipe, all we need to do is divide 64 by 32 to find out how many cartons we need!</em>

<em>64 fluid ounces (8 cups worth) ÷ 32 fluid ounces (per carton) = 2 cartons</em>

Melina needs to buy 2 cartons of broth to be able to complete her recipe.

Hope this Helps! :)

There are 12 peaches and 8 bananas in a fruit basket. You get a snack for yourself and three of your friends by choosing of the
muminat

Answer:

10.2% chance

Step-by-step explanation:

There are 12 peaches and 8 bananas for a total of 20 pieces of fruit.

So we can write it:

\frac{12}{20}  *  \frac{11}{19} *  \frac{10}{18} *  \frac{9}{17} =  \frac{11880}{116,280} = .102 or 10.2% chance

For ease multiply all numerators (top numbers) together, then multiply the denominators (bottom numbers) together, and then divide.

12 * 11 * 10 * 9 = 11880

20 * 19 * 18 * 17 = 116,280

We start with 12 peaches and 20 total fruit, as we select a peach the number of peaches and total fruit goes down by one. We do this 4 times because you draw 4 fruits. If you select 1 fruit your chances of it being a peach are 12/20, each time you select a fruit the chances of it being a peach go down because you have 1 less total fruit, and 1 less peach. This is why you multiply each probability together.
