Emily had 30 cookies to bring to school for her birthday. Three students wanted two cookies each. Then, a new student came that day and he wanted three cookies. Then, one of the three kids gave their cookies back. Emily was still passing out cookies. How many cookies did Emily have Pass out After the Student gave their Cookies Back?

Answers

21

30-6=24-3=21+2=23

3x2=6

Não sei se é isso

Ok, let’s see here. Emily had a total of 30 cookies, and right off the bat 3 students wanted 2 cookies. 3 times 2 is 6, so that’s already 6 cookies taken away. 30 minus 6 is 24, so currently she has 24 cookies left. Then, one of those 3 kids gave only ONE cookie back, so we take 24, and add 1. Giving us 25. We are trying to see how many cookies Emily has passed out so far, so we take the original number, which is 30, and subtract that by our current number which is 25. Giving us 5, meaning she has passed a total of 5 cookies so far.

Answer:

2(n + 8)  

Step-by-step explanation:

From the question we know that what he does is basically he takes the number n, and adds 8 to it, and then multiplies the resulting sum by 2. so we can write that down as...

(n + 8) x 2 = 2(n + 8) = 2n + 16

In Jaunary your Verizon cell phone bill costs $12 for 80 minutes and in March your bill costs $9 for 60 minutes.

A) Determine whether the rate at which you are being charged for your phone bill is proportional to the amount of minutes being used. Explain.

Answers

Both rates are same when you divide them. 80/12= 6.6667 and 60/9= 6.667.

So, 6.6667 is the rate for each minute

The measures of two supplementary angles have a ratio of 4:5. What is the measure of the larger angle?

The measure of the larger angle is
°. what is the angle

Answers

First, we know that all supplementary angles add to 180°. Then, since the angles are in the ratio 4:5, we can also represent these angles as 4x and 5x respectively. Both angle measures have the same variable (x) because no matter how large the angles are, they must have a common multiple because they are in a ratio. We can then write the formula 4x+5x=180 and solve for x. First, you combine like terms to get 9x=180. The you divide both sides by 9 to get x=20. Then, we can find both angles to be 80 (4*20) and 100 (5*20) by plugging them into 4x and 5x.

Got the answer from sdmatera (i’m giving creds)

How can you isolate the variable in this inequality?

3b < -99.

A
Subtract 99 from 3b.

B
Add 99 to both sides.

C
Divide both sides by 3.

D
Multiply both sides by 3.

Answers

Answer:

C- Divide both sides by 3.

Step-by-step explanation:

In order to isolate the variable, we will have to remove all non-1 coefficients from the variable. Since 3b can be written as 3(b), b is being multiplied by 3. So the only way to isolate the variable is to do inverse operations, which would be to divide both sides of the inequality by 3.

Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.

Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.

Answers

A simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years is given as follows:

Choose three numbers with replacement from the set of 0 to 9, which:

numbers from 0 to 3 representing that Phil is correct.numbers from 4 to 9 represents that Phil is incorrect.

How to calculate a probability?

The parameters that are needed to calculate a probability are given as follows:

Number of desired outcomes in the context of a problem/experiment.Number of total outcomes in the context of a problem/experiment.

Then the probability is calculated as the division of the number of desired outcomes by the number of total outcomes.

The probability of a success on a single trial is given as follows:

40% = 0.4, as Phil is correct 40% of the time.

Hence the simulation needs to have three trials, each with a 0.4 = 40% probability of a success.

Answer: 21

Step-by-step explanation: We can use the method: Keep, Change, Flip.

1. Keep 7.

If you want 7 to become a fraction, you can do it like this: [tex]\frac{7}{1}[/tex]

2. Change division to multiplication.

It's very simple. Just change the sign.

3. Flip [tex]\frac{1}{3}[/tex].

It's like converting it into a improper fraction. [tex]\frac{1}{3}[/tex] is now [tex]\frac{3}{1}[/tex].

Now we can solve!

[tex]\frac{7\times3}{1\times1} =21/1[/tex]

Therefore, your answer is 21/1 or just 21.
