There are 10 doors to a coliseum. In how many ways can a person go in and out if one can enter any door but leave using another door? Use permutation formula (P(n,r)) to solve.

Answer:

52cm^2

Step-by-step explanation:

I did the splitting in my head and that's pretty hard to explain like this so, just BTW if your confused on where I got my lengths from.

(7*6) + (5*2)

(42) + (10)

52

I separated them into an almost square and a rectangle, then I found the area of each rectangle and then added them together.

Hopefully this was useful and you didn't have any issues with this!

Answer:

x = 24°

Step-by-step explanation:

the sum of the interior angles in a triangle = 180°

so:

(2x + 5°) + 64° + 3x - 9° = 180°

combine like terms:

5x + 60° = 180°

subtract 60° from each side of the equation:

5x = 120°

x = 24°

Answer:

2

Step-by-step explanation:

Answer:

let angle e be x

x+4x+10=180°[by linear pair]

5x+10=180°

5x=180-10

5x=170

x=170/5

x=34

angle E=34°

angle E+angle C+angle D=180°[by angle sum property]

34°+70°+2x=180°

104°+2x=180°

2x=180°-104

2x=76°

angle d=76°

Answer:

A = 3x^2 - 2x - 1

Step-by-step explanation:

3x times x equals 3x^2

(3x times - 1) + (x times 1) = -2x

1 times -1 = -1

put the partial products together, you get the above answer.

Answer:

  C  The cost of living will increase by approximately 5% each year

Step-by-step explanation:

If we assume your function is ...

  [tex]f(x)=34000(1.05)^x\qquad\text{x is years}[/tex]

Then the growth factor 1.05 represents a growth rate of 1.05 -1 = .05 = 5% per year. The positive growth rate means the cost of living is increasing.

Noah's cost of living is increasing about 5% per year.

Answer:

7

Step-by-step explanation:

Note the values on the right are 7 times the corresponding value on the left side, that is

15 × 7 = 105

12 × 7 = 84

4 × 7 = 28

Then

1 × 7 = 7 ← required value

Answer:

7 or B

Step-by-step explanation:

28/4=7

12*7=84

7 is the number you multiply the first row by to get tbe second row. 1*7=7

Answer:

Cost of 1 bushes = a = $9

Cost of 1 tree = b = $73.5

Step-by-step explanation:

Given:

13 bushes and 4 trees cost = $411

Missing;

6 bushes and 2 trees cost = $201

Find:

Value of bushes and tree

Computation:

Cost of 1 bushes = a

Cost of 1 tree = b

So,

13a + 4b = 411 ...........eq1

6a + 2b = 201 ................eq2

From Eq1 and Eq2

Cost of 1 bushes = a = $9

From eq 1

13a + 4b = 411

13(9) + 4b = 411

Cost of 1 tree = b = $73.5

(-5s¹²)/ (2t³³) is the Simplified form of the Given equation.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given an equation [tex](\frac{5s^{2}t^{-7} }{-2s^{-2}t^{4} })^{3}[/tex]

Simplifying using PEMDAS

First, we will solve the power

=> (-5/2 s²⁺² t⁻⁷⁻⁴)³

=> (-5/2 s⁴ t⁻¹¹)³

=> (-5s¹²)/ (2t³³)

Therefore, the Simplified notation of the Given equation is (-5s¹²)/ (2t³³).

Complete question:

Answer:

Step-by-step explanation:

The easiest and most proper way to approach this task is to combine like terms inside parentheses:  (24x + 7 – 12x) => (12x + 7).

Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7).  This is an acceptable answer.  There is the option of carrying out the multiplication, which results in

3x + 7/4, which is another acceptable answer.

5 + 8 + 1 + 2 + 10  =  26 (divided by) 5 = 5.2

The mean and the standard deviation of the data set is 5.2 and 3.429.

The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.

We have,

Data:  {5, 8, 1, 2, 10}.

So, the mean of data

= (5+ 8 + 1 + 2 +10)/ 5

= 5.2

Then, the Value of Deviations

-0.2, 2.8, -4.2, -3.2, 4.8

So, the variance is

= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5

= 11.76

And, Standard deviation is

= 3.429

Answer:

Step-by-step explanation:

Answer:

- 362.5t + 1100

Step-by-step explanation:

Given :

Value, = v ; time, = t

t1, v1 = (0, 1100)

t2, v2 = (2, 375)

Slope, m = v2 - v1 / t2 - t1

m = (375 - 1100) / (2 - 0)

m = - 725 / 2

m = - 362.5

v - v1 = m(t - t1)

v - 1100 = - 362.5(t - 0)

v - 1100 = - 362.5t

v = - 362.5t + 1100

Answer:

10.3

Step-by-step explanation:

The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.

[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]                            

We find the square root of both sides to find the value of c.

10.295 ≈ c

Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3
