4.A small pizza has a diameter of 21 cm.

What is the approximate circumference of the pizza? $\pi$ = 3.14.

Answers

Answer 1

Answer: Well, circumference formula is pi times diameter.
$C= \pi d$
So, all you have to do is multiply the given diameter by pi to get your circumference in centimeters.
21·3.14=65.94

Circumference is 65.94 centimeters

65.94cm

Solve the inequality. 6x + 3 > 3x + 30

Answers

6x+3>3x+30

The thing about solving inequalities, you just need to treat the symbol, which is the less than symbol in this case, as an equal sign.

So our problem becomes: 6x+3=3x+30

Now we solve this like a normal algebra problem.

First, get all the variables on one side. Since 3x is smaller than 6x, we'll get rid of that by subtracting it from each side.

3x+3=30 is what we end up with.

Now to get the variable alone and get rid of that constant. To do that, we are going to subtract 3 from each side.

We end up with 3x=27

Now, to get the 'x' alone, we need to divide each side by 3.

x=9 is what we end up.

BUT WE FORGOT TO DO SOMETHING

We started this as an inequality problem, so we need to end it as an inequality solution.

Since there wasn't any negatives we need to worry about (Which is something else entirely) we just need to transfer the symbol we started with down.

x>9

Each morning a deli worker has to make several pies and peel a bucket of potatoes. on Monday it took the worker 2 h to make the pies and an average of 1.5 min to peel each potato. on Tuesday the worker finished the work in the amount of time but it took 2.5 h to make the pies and an average of 1 min to peel each potato. about how many potatoes are in a bucket?• what qualities do you know and how are they related to each other?
• how can you use the known and unknown quantities to write an equation for this situation?

Answers

Let the number of Potatoes = P

On Monday the time spent was 2 hours + 1.5*P minutes
Convert the time to make the pies into minutes = 120 minutres
Therefore on Monday the worker took

120 + 1.5P minutes

On Tuesday the worker took 2.5 hours (150 minutes) + 1minute x P
ie
150 + P minutes

We are told that the times are the same therefore
120 + 1.5P = 150 + P
subtract P from both sides of the equation
120 + 0.5P = 150
Subtract 120 from both sides of the equation
0.5P = 30

Therefore P = 30/0.5 = 60

There are 60 potatoes in the bucket.

HELP; The life spans of 10 adult mayflies have a mean of 4 hours and a MAD of 2 hours. Fill in the table below with possible values for the life spans. You can use the same values more than once. Can any one of the 10 mayflies in the group live for 1 full day? Justify your answer.

Answers

No, any one of the 10 mayflies in the group live for 1 full day.

What is the absolute mean deviation?

The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations and their mean.

The life spans of 10 adult mayflies have a mean of 4 hours and a MAD of 2 hours.

Fill in the table below with possible values for the life spans. You can use the same values more than once.

Mean = 4 hours.

Mean absolute deviation = 2 hours.

Assume that the life spans of each fish is 4 hours;

Then mean = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4/10

= 40/10

= 4 hours.

No fish can live for a full day.

Hence, No, any one of the 10 mayflies in the group live for 1 full day.

#SPJ2

Step-by-step answer:

Assuming MAD stands for mean absolute deviation (2 hours), then the total absolute deviation from the mean (4 hours) is 10*2=20 hours.

If one of the flies live for 1 full day, the absolute deviation is 24-4=20 hours. This automatically requires the other flies live exactly 4 hours to have the MAD equal to 20 hours.

However, the above arrangement does not give a mean of 4 hours, but a mean of (24+9*4)/10=6 hours. This means that it is not possible to have a fly living for a full day.
