A bag contains 2 red marbles, 4 blue marbles and 8 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that both marbles drawn will be blue?

Answer: w =1 L=6

Step-by-step explanation:

What is Perimeter = 2 L + 2W

2L + 2B =14

L = 2W + 4

2(2W + 4) + 2W = 14

4W +8 +2W =14

6W=14-8

W=1

L=2W +4= 6

Answer:

21 of them aren't brown

How 2 solve:

Subtract

39-18= 21

[tex]7x + 8 = ( - 5x) + 32 \\ 7x + 5x = 32 - 8 \\ 12x = 24 \\ x = \frac{ \cancel{24} {}^{ \: \: \: 2} }{ \cancel{12}}\\x=2 [/tex]

[tex] \Large{\boxed{\sf x = 2}} [/tex]

[tex] \\ [/tex]

Given equation:

[tex] \sf 7x + 8 = -5x + 32 [/tex]

[tex] \\ [/tex]

Substract 8 from each side :

[tex] \sf 7x + 8 - 8 = -5x + 32 - 8 \\ \\ \sf 7x = -5x + 24 [/tex]

[tex] \\ [/tex]

Add 5x to both sides :

[tex] \sf 7x + 5x = -5x + 24 + 5x \\ \\ \sf 12x = 24 [/tex]

[tex] \\ [/tex]

Divide both sides by 12 :

[tex] \sf \dfrac{12x}{12} = \dfrac{24}{12} \\ \\ \\ \boxed{\boxed{\sf x = 2}} [/tex]

The game is an illustration of probability, and the probability that each player wins is 1/12

From the question, we have the following parameters:

Number of a pair of numbers = 3

A die has 6 possible outcomes.

So, the probability of getting the first pair is:

P1 = 1/6

The probability of getting the second pair is:

P2 = 1/6

The probability of getting the first and the second pairs is

P = 1/6 * 1/6

Evaluate

P = 1/36

There are three pairs of numbers in total.

So, the probability of winning is:

P(Win) = 3 * 1/36

Evaluate

P(Win) = 1/12

Hence, the probability that each player wins is 1/12

Step-by-step explanation:

Step-by-step explanation:

[tex]180 = 70 + 90 + y \\ y = 20 \\ (x + y + 18) + 44 + 90 = 180 \\ y = 8[/tex]

Step-by-step explanation:

by the way, you are completely and exactly right at 6.

Q is the inscribed angle of the (inner) arc angle TR.

and as such it is half of that arc angle TR.

S is now on the same side of the circle center as the segment TR. so, we have to flip the situation around :

S is half of the outside arc angle between T and R.

as the sum of the inner and outside arc angles are 360° (the full circle), the sum of half of their values is then

360/2 = 180°

so, yes,

x + 2 + 9x - 7 = 180

10x - 5 = 180

10x = 185

x = 18.5

Q = x + 2 = 18.5 + 2 = 20.5°

S = 9x - 7 = 9×18.5 - 7 = 166.5 - 7 = 159.5°

Answer:

$43.30

Step-by-step explanation:

What we know,

3 hamburgers = $12.99

Coleman wants to know how much would he have to pay for 10 hamburgers,

In order to find out how much 10 hamburgers cost, you need to find out how much 1 hamburger costs,

To find how much 1 hamburger costs divide 12.99 by 3,

12.99/3

= 4.33

Now we know that 1 hamburger cost $4.33,

Now time to find out how much 10 hamburgers cost,

Multiply 4.33 by 10,

4.33 × 10

= 43.30

Therefore it cost $43.30 for 10 hamburgers.

Any smooth curve connecting two points is called an arc. The correct option is c.

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]

where

θ is the angle, that arc creates at the centre of the circle in degree.

If the central angle has a measure of π/2(90°), then the length of the arc will be one-fourth of the total, while if the measure of the angle is π(180°), then the length of the arc will be half of the total.

Similarly, if the measure of the angle is 3π/4, then the length of the arc will be three-fourth of the total, while if the measure of the angle is 2π(360°), then the length of the arc will be 2πr.

Hence, the correct option is c.

Based on the calculations, the total distance of Mara's run is equal to: C. 12 km.

In order to determine the total distance of Mara's run, we would solve for the length of the hypotenuse by applying Pythagorean's theorem and then add it to the other distances.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

Substituting the given parameters into the formula, we have;

c² = 3² + 4²

c² = 9 + 16

c = √25

c = 5 km.

Total distance = 3 + 4 + 5

Answer:

Step-by-step explanation:

The length which result in a ratio closest to the golden ratio is equal to  7.5 inches and 4.5 inches. Option C is correct.

The line segment is made with two end points. Length of a line segment is the distance of both the ends of it.

A 12 inch line segment is divided into two parts. Suppose the line segment is AC which is divided into AB and BC parts. Thus,

AB+BC=AC

AB+BC=12                   ....1

The value of golden ratio is equal to 1.618. It can also be given as (1+√5)/2. The ratio of both segment is equal to golden ratio. Thus

[tex]\dfrac{AB}{BC}=\dfrac{AC}{AB}=\dfrac{1+\sqrt{5}}{2}\\\dfrac{12}{AB}=1.618\\AB=7.4166 \rm\; in[/tex]
