Ik it sucks I hate math too, pls help tho

Answer: Perimeter → 15.07964474

Area→ 18.09557368

Answer: -2; -1; 0; 1; 2

[tex]-8\leq 4n<12\\\\=> -2\leq n<3[/tex]

because n is an integer => n ∈ {-2; -1; 0; 1; 2}

Step-by-step explanation:

Answer is : n ={-2; -1; 0; 1; 2}

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.

here, we have,

given that,

-8 ≤ 4n < 12

=> -2≤ n <3

because, n is an integer => n ∈ {-2; -1; 0; 1; 2}

Hence, Answer is : n ={-2; -1; 0; 1; 2}.

Answer:

Row 15 is correct

Step-by-step explanation:

Pascal's triangle:  

                                              1                                            n = 0 , Row = 0

                                      1                 1                                  n = 1  , Row = 1

                             1               2                1                          n = 2 , Row = 2

                                               :

                                          .........

                                           .......

For n = 0, Row number 1  

For n = 1,  Row number 2

For n = 2, Row number 3

We make pascal's triangle but sum of above two number, write below.  

As we can see in pascal's triangle.  

Exponent represent the number of row.  

If binomial has exponent n then nth row of pascal's triangle use.  

For  

Here power is 15  

So, we have to use 15 row of pascal's triangle.  

Hence, Row 15 is correct

Answer:

x = 3

Step-by-step explanation:

24 = 9x -3

(add 3)

27 = 9x

(÷9)

x = 3

Answer:

x = 3

Step-by-step explanation:

Assuming QTSR is a parallelogram, then segment QT is of equal length to segment SR. Solve for x by writing the equation 9x - 3 = 24

Answer:

1 1/8

Step-by-step explanation:

Answer:

1 1/8

Step-by-step explanation:

Answer:

1. 3 cookies

2. 2 cups

3. 300 calories

4. $35 per month

5. k = y/x

6. If there is no constant (k)

Step-by-step explanation:

1. The number of cookies the factory makes in one minute = (The number of cookies the factory makes in 12 minutes)/(12 minutes)

∴ The number of cookies the factory makes in one minute = 36 cookies/(12 minutes) = 3 cookies/minute

The correct answer is 3 cookies

2. The number of cups of water that leak every minute = (The number of cups of water that leak in 1/4 minute) × (The number of 1/4 minute per minute)

The number of cups of water that leak every minute = 1/2 cup per 1/4 minute × 4_1/4 minute per minute

The number of cups of water that leak every minute = 1/2  × 4 = 2

The number of cups of water that leak every minute = 2 cups

3. 5 glazed donuts contains 750 calories

∴ 1 glazed donuts contains 750/5 = 150 calories

2 = 2 × 1 glazed donuts will contain 2 × 150 = 300 calories

4. The charge of the cell phone company for 2 months = $70

The charge of the cell phone company for 6 months = $210

The constant rate per month = The rate of change of the cell phones companys charges

∴ The constant rate per month = (210 - 70)/(6 - 2) = 140/4 = 35

The constant rate (per month) for the service = $35 per month

5. The formula to find the constant of a chart, k = y/x

6. A chart is not considered proportional if there is no constant (k)

Answer:

x = 120 degrees

Step-by-step explanation:

a hexagon has a total of 720 degrees

720- 130-140-150-90-90= 120

Answer:

answer is 50

Step-by-step explanation:

x =180-(65+65)

x=180-130

x=50

Answer:

1) C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) Continuous

Step-by-step explanation:

1) The given parameters are;

The base fee charged = $25

The amount charged for labor = $40/hour

The total cost for h number of hours is C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) The situation is continuous because the different input values of h can be infinite (from o to infinity)

Answer:

C

1/3y - 7/5×+ 2/3-2/3 y- 4/9

Answer: X- 4y - 12=0

step by step explanation:

First, move the constant to the left by adding its opposite to both sides

x-4y -12 = 12-12 =

X-4y-12 =  0

So the answer is X- 4y - 12=0
