The correct answer for this would be -10
Use distributive property
4x + 8 = 2x - 12
Add 12 to both sides
4x + 20 = 2x
Subtract 4x to both sides
20 = -2x
Divide by -2, x = -10

Tom swam to the bottom of a swimming pool that was 9 feet deep and he touched
the bottom. He swam back to the surface. How many feet did Tom swim?

Answers

Answer:

18 feet

Step-by-step explanation:

9 x 2 = 18

Answer: 18 feet

Reason: he swam 9 feet going down the pool, but he didn’t just stay under there, he swam back up to the surface.
Thus we can 9 (feet for swimming to the bottom) plus 9 ( feet for swimming to the top).

A saleswoman is paid $80 a day plus $6 for each sale she makes. She wants to earn more than $150 today. Write an inequality that represents the number of sales, x, the saleswoman must make today to earn more than $150. What is the least number of sales she must make to reach her sales goal

Answers

Answer:

12

Step-by-step explanation:

Given that:

Daily wages paid to a saleswoman = $80

Wages paid for each sale made by her = $6

Target of today's earnings = more than $150

To find:

Least number of sales to be made so that the total earnings today is more than $150.

Solution:

Number of sales for today = [tex]x[/tex]

Wages for one sale = $6

Wages for [tex]x[/tex] number of sales = $6[tex]x[/tex]

Total earnings = Per day sales + Wages for [tex]x[/tex] number of sales > $150

[tex]80 + 6x > 150[/tex]

we need to solve for above inequality to find the least number of sales to be made to meet the goal.

Subtracting 80 from both sides:

[tex]\Rightarrow 6x>70\\[/tex]

Dividing both sides by 6:

[tex]\Rightarrow x > 11[/tex]

Therefore, at least 12 sales must be made.

what is the birthday polynomial project for 05/11/2004?

Answers

Answer:

OBJECTIVE: To create, characterize and graph a polynomial function that reflects you!

PROCESS:

1. Write, IN ORDER, the digits of the month (1 or 2 digits), day (1 or 2 digits), and year (4 digits) of your birthday.

For example, April 2, 1976 could be “421976” or “4021976”. Use must use 6, 7 or 8 digits.

2. Create a polynomial using your digits, in order. Again, for example, my polynomial could be:

() = 4

5 + 2

4 − 1

3 − 9

2 + 7 −6 or

() = 4

6 + 2

4 − 1

3 − 9

2 + 7 − 6

*notice in the second example, the 0 eliminated the 5th degree term

**if your birth year is 2000, you may change your constant term (the “lagger”, which is the 6 in my

equation) to your favorite number, instead of 0.

3. Experiment with the shape of your birthday polynomial by changing the signs (+/-) of various terms in your

calculator. Try to create a polynomial function with an interesting shape and some turning points. Be creative!

You’re trying to express yourself in this graph!

*notice the change in the 2 graphs

below by just changing 3 positive

signs to negative!

4. Analyze your polynomial (using your calculator)

by finding these characteristics:

a. Roots (x-intercepts)

b. Y-intercept

c. Relative minimums and maximums

d. End behavior

e. Points (x, y)

PRODUCT: Make a presentation of your polynomial. Be creative! Be colorful! Be neat! Be artistic and ACURATE! Just

meeting the basic requirements will earn you a 90% (at most). At a minimum, your presentation should include a visual

representation of the graph of your polynomial and should also include the following:

□ The statements: My Birthday is ________________

My Birthday Polynomial is ______________________.

□ A T-chart with 10 (x, y) points

□ All Roots (labeled on graph and values)

□ Y-intercept (labeled on graph and value)

□ Relative Maximum and Minimums (labeled on graph and values)

□ Sentence description of end behavior and why this occurs

ASSESSMENT: Your project will replace lowest MID-CHAPTER QUIZ (30 points). You will be graded on completion of all

requirements and accuracy of graph and values. Additional points (90% and above) will be awarded for creativity and

effort.

YOUR PROJECT IS DUE WEDNESDAY, DECEMBER 2. ABSOLUTELY NO LATE PROJECTS WILL BE ACCEPTED. PLEASE FEEL

Step-by-step explanation:

The birthday polynomial for the date 05/11/2004 is 20040511.

The birthday polynomial is a mathematical concept that assigns a unique polynomial to a specific date, typically represented in the format MM/DD/YYYY.

To construct the birthday polynomial for a given date, follow these steps:

1. Write the date in the format MM/DD/YYYY.

2. Rearrange the numbers in reverse order, i.e., YYYY/MM/DD.

3. Remove any slashes or separators between the numbers.

To construct the birthday polynomial for the date 05/11/2004, follow these steps:

1. Write the date in the format MM/DD/YYYY: 05/11/2004

2. Rearrange the numbers in reverse order: 2004/05/11

3. Remove the slashes: 20040511

a regular square pyramid is 3m height and the perimeter of its base is 16m find the volume of the prism if its height is 10cm.​

Answers

Answer:

240

Step-by-step explanation:

Answer:

16 m^3

Step-by-step explanation:

Question:

"a regular square pyramid is 3m height and the perimeter of its base is 16m find the volume of the pyramid"

volume of pyramid = (1/3) * (area of base) * height

The perimeter of the base is 16 m, and the base is a square.

perimeter of square = 4 * side

4 * side = 16 m

side = 4 m

area of square = (side)^2

area of base = (4 m)^2 = 16 m^2

volume of pyramid = (1/3) * (area of base) * height

volume = (1/3) * (16 m^2) * 3 m

volume = 16 m^2

On a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions. The test is worth a total of 100 points. There are twice as many
2-point questions as 5-point questions on the test. How many 2-point questions are on the test?
•8
•4
•12
•16

Answers

Answer:

B. 8

Step-by-step explanation:

Calculate how many 2 point answers and 5 point answers there are.

2 x 8 = 16

Since there are half as many 5 point answers as there are 2 point answers,

5 x 4 = 20

calculate how many remaining questions there are. The numbers would be 8 since you had 8 2 point questions and 4 since half of 8 is four.

8 + 4 = 12

Subtract that number by the total questions, which is 28.

28 - 12 = 16

Next figure out how many 4 point questions you had (28-12=16)

16 x 4 = 64

To check your work add up the totals and see if they match up to 100.

16 + 20 + 64 = 100
