Maria pulls colored marbles out of a bag one at a time. Her results are shown in the table below.

Color Outcomes
Blue 36
Yellow 42
Black 18
White 24

Based on the outcomes, if 20 more marbles are pulled out of the bag and replaced, how many marbles can be expected to be white?

Answer:

Nicholas pulls 5 blue marbles from the bag.

Step-by-step explanation:

Since Nicholas performs an experiment in which he pulls a marble from a bag, and in his experiment, he finds that he is twice as likely to pull a red marble as a blue marble, to determine, if Nicholas pulls 10 red marbles, how many blue marbles does he pull, the following calculation must be performed:

10/2 = X

5 = X

Therefore, Nicholas pulls 5 blue marbles from the bag.

Explanation:

We have c^2 + 2c, where 2 is the coefficient of the c term

This halves to 2/2 = 1, and then we square that to get 1^2 = 1.

Adding 1 to c^2+2c will result in c^2+2c+1, allowing it to be factored. This is because it's a perfect square

The rule we use is

(a+b)^2 = a^2 + 2ab + b^2

Answer:

x = 5

Step-by-step explanation:

Since this shape is a quadrilateral, the sum of the interior angles is 360.

Equation:

81 + 20x - 16 + 15x + 30 + 16x + 10 = 360

51x + 105 = 360

51x = 360 - 105

51x = 255

x = 5

Answer:

780

Step-by-step explanation:

24 - 67 = - 43

- 43 - 88 = - 131

- 131 + 77 - 77 = - 131

- 131 + 78 = - 53

- 53 - 55 = - 108

- 108 + 888 = 780

Answer:

Option D. 4√2

Step-by-step explanation:

8/√2

The above expression can be simplified as follow:

8/√2

Rationalise the denominator i.e multiply the numerator and the demoninator by √2. This is illustrated below:

8/√2 × (√2/√2)

8 × √2 / √2 × √2

8√2 / 2

4√2

Thus, option D gives the correct answer to the question.

Answer:

3295000

Step-by-step explanation:

3295×999+3295

3295 * 999 = 3291705

3295×999+3295

3295 * 999 + 3295

3291705 + 3295 = 3295000

Answer:

12 and 10

Step-by-step explanation:

Answer:

11 and 21

Step-by-step explanation:

Let the first number equal x. If the first number, the second number is ten more, and can represented as x + 10. Now, the sum is 32, so we can add the two numbers to get 32:

x + x + 10 = 32

2x + 10 = 32

2x = 22

x = 11

If the first number 11, the second number is 10 more, and therefore is 21.

b) 7x² - 12x√14 + 72

Step-by-step explanation:

Let's solve the problem,

→ (x√7 - 3√8)(x√7 - 3√8)

→ (x√7 - 3√8)²

→ 7x² - 12x√14 + 72

Hence, option (b) is correct.

Answer:

X= -12 Y=10

Step-by-step explanation:

The solution is, Solve of the system of equations.

9x+11y=2 & 3x+4y=4 is, x = -12 & y =10.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

given that, the system of equations.

9x+11y=2 .......(1)

3x+4y=4 ...........(2)

now, for solving, multiply (2) by 3 & subtract from (1),

we get,

9x + 11y =  2

9x + 12y = 12

---------------------

y= 10

from (1), we get, x = -12

Hence, The solution is, Solve of the system of equations.

9x+11y=2 & 3x+4y=4 is, x = -12 & y =10.

Answer:

375 miles

Step-by-step explanation:

Create a proportion where x is the number of miles she can drive on 12.5 gallons of gas:

[tex]\frac{96}{3.2}[/tex] = [tex]\frac{x}{12.5}[/tex]

Cross multiply and solve for x:

3.2x = 1200

x = 375

So, with 12.5 gallons of gas, Sara can drive 375 miles

Answer;

14x-12

Explanation:

Since we are not asked what to fine, we can find the perimeter of the rectangle

Perimeter = 2(L+W)

Perimeter = 2(2x+1+5x-7)

Perimeter = 2(7x - 6)

Perimeter = 14x - 12

Hence the perimeter of the rectangle is 14x-12
