Ihave a bag of m& m's. there are 9 green m& m's and this is 30% of the bag. how many total m& m's are in the bag?

30 total m&m's

Step-by-step explanation:

You want to find the rest of the bag, which is 70% of the bag (100% - 30%). The question is basically asking: What is 70% of x if 30% of x is equal to 9? The variable x represents the total m&m's in the bag.

Create an equation that models 30% of x.

To solve for x, divide both sides of the equation by 0.3.

We know that the value of x is 30, so this means that there is a total of 30 m&m's in the bag. However, to check your answer substitute the value of x into the expression for "What is 70% of x?"

This question can be modeled by: 70%x or 0.7x.

Substitute 30 for x.

Now take this amount and add this to the known amount of green m&m's in the bag.

After checking our answer we can verify that 30 is the correct answer.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

yes. we do proportions in probabilities.
