Step-by-step explanation:

The two angles are supplementary angles, which when added together equal 180 degrees.

6x -10 + 6x +10 = 180

Combine like terms:

12x = 180

Divide both sides by 12:

x = 180/12

x = 15

Answer:

No. The correct solution is (3,-1)

Step-by-step explanation:

Since we are using elimination method, we can go ahead and see that we can cancel "-y" from the first equation and "+y" from the second equation.

Once  we do that, we go ahead add the like terms and get 3x = 9

Then, we divide by 3 on each side and get  x = 3

Now, we can take that value of x and plugin to any of the original 2 equations we started with.

Say we plugin x = 3 into the second equation.. it will turn to, 2(3) + y = 5

Then we solve for y.

2(3) + y = 5

6 + y = 5

6 - 1 = 5

y = -1

There, we found our x value and our y value, (3,-1)  :)

Answer:

Step-by-step explanation:

Because 10 times 4 is 56

The shaded region is 1/4 of the whole circle. Thus, the area of the shaded region is 78.5 square units.

Let r be the radius of the sector and θ be the angle subtended by the sector at the center. Then the area of the sector of the circle will be

Arc = (θ/2π) πr²

The radius is 10 units and the angle is π/2. Then the area of the shaded region is calculated as,

A = [(π/2)/2π] π x 10²

A = 3.14 x 10 x 10 / 4

A = 78.5 square units

More about the area of the sector link is given below.

Answer:

Mean: 3.6

Median: 3.5

Mode: 2

Step-by-step explanation:

Mean: The sum of all numbers divided by the amount of numbers.

Median: The number in the middle.

Mode: the number that is frequently used.

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

Mean: 1 + 4 + 8 + 3 + 4 + 5 + 2 + 2 + 2 + 5 = 36 ÷ 10 = 3.6

Median: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. since two numbers are in the middle, we need to add 3 + 4 ÷ 2 = 3.5

Mode: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. The mode is two because it is used the most.

Answer:

1/6

Step-by-step explanation:

The multiplicative inverse of a number is that number as the denominator, and 1 as the numerator. Let's solve this problem using that knowledge.

6 × ? = 1

6 × m = 1

(m stands for multiplicative inverse)

m = 1/6

The length of the longer piece is 124/7.

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

let the two pieces be x(longer) and y (shorter)

So,

x+y=31

and, 3x=4y

3x-4y=0

Solving both the equations:

x= 124/7 and y=93/7

Hence, the length of longer piece is 124/7.

3 yellow + 7 green = 10 total marbles.

The probability of picking a certain color is the number of that color over the total quantity.

Picking yellow would be 3 yellow / 10 total = 3/10

Picking green would be 7 green / 10 total = 7/10

To find the probability of doing both multiply the probability of each one by each other:

3/10 x 7/10 = 21/100

The answer would be 21/100

Answer:

cosθ = [tex]\frac{12}{13}[/tex]

Step-by-step explanation:

Given

sinθ = - [tex]\frac{5}{13}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]

This is a 5- 12- 13 right triangle

with opposite = 5, adjacent = 12 , hypotenuse = 13

since θ is in 4th quadrant then cosθ > 0

cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{12}{13}[/tex]

The trigonometric ratio of cos θ in quadrant IV is 12/13.

Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.

For the given situation,

Sin θ = -5/13, and

θ lies in the quadrant IV.

By trigonometric ratio,

[tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]

⇒ [tex]sin \theta = -\frac{5}{13}[/tex]

Here opposite side = 5 and

hypotenuse side = 13

The adjacent side can be calculated by using the Pythagoras theorem,

[tex]Hypotenuse^{2} = opposite^{2} +adjacent^{2}[/tex]

⇒ [tex]adjacent = \sqrt{hypotenuse^{2} -opposite^{2} }[/tex]

⇒ [tex]adjacent = \sqrt{13^{2} -5^{2} }[/tex]

⇒ [tex]adjacent = \sqrt{169 -25 }[/tex]

⇒ [tex]adjacent = \sqrt{144}[/tex]

⇒ [tex]adjacent = 12[/tex]

Thus [tex]cos \theta = \frac{adjacent}{hypotenuse}[/tex]

⇒ [tex]cos \theta = \frac{12}{13}[/tex]

θ lies in the quadrant IV, so cos θ > 0.

Hence we can conclude that the trigonometric ratio of cos θ in quadrant IV is 12/13.
