==========================================================

Explanation:

We have n = 8 sides for this octagon.

This means the interior angles sum to 180(n-2) = 180(8-2) = 180*6 = 1080 degrees.

The tickmarks tell us that each side is the same length, so we have a regular octagon. This means that all 8 angles are the same measure. Let's say each angle is y degrees.

1 angle = y degrees

8 angles = 8y degrees

Solving 8y = 1080 leads to y = 1080/8 = 135

Each angle of this regular octagon is 135 degrees.

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

Now set 16x+23 equal to 135 and solve for x

16x+23 = 135

16x+23-23 = 135-23

16x = 112

16x/16 = 112/16

x = 7

Answer:

2) 520

3) 135

4) 490

5) 850

Step-by-step explanation:

2) 10 regular for every 2 premium. so 12 total. Then we do 624 divided by 12 so we get 52. So we multiply 10 by 52 and 520. So they have 520 regular subscribers.

3) 3 short sleeves for every 9 long sleeves. So 12 in total. 540 divided by 12 is 45. 45 times 3 is 135. So 135 short sleeves were sold.

4) 7 teens for every 2 adults. so 9 in total. 630 divided by 9 is 70. 70 times 7 is 490. So 490 of the people who voted were teens.

5) For every 10 songs he like there was 5 he disliked. So 15 in total. 1275 divided by 15 is 85. 85 times 10 is 850. He liked a total of 850 songs.

Answer:

Step-by-step explanation:

If the zero occur when x={5, -2, -1} then the equation must be

(x-5)(x+2)(x+1) if expansion is desired

(x^2-3x-10)(x+1)

x^3+x^2-3x^2-3x-10x-10

x^3-2x^2-13x-10

Answer:

2x-3y=6

Step-by-step explanation:

To keep it short, since one of the points o the equation 2x-3y=6 is on the line and is the center of the non rigid transformation we can stretch or compress however long we want, the equation or slope will stay the same since slopes are proportional for example the slope in this problem is 2/3. If we multiply the line by a scale factor of 2, the lines are similar and the slope is 4/6 which is the same as 2/3. So the equation stays the same

Answer:

-43/50

(decimal) = -0.86

Step-by-step explanation:

Find the LCD which is 50.

16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50

3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50

subtract them which will give you -43/50

Answer:

I think it's 8.7

Step-by-step explanation:

if you divide 6.5 by 3, you get 2.16666666667, so that is how long it takes to make 1 CD liable. Multiple that by 4 and round and you get 8.7.

If I'm wrong I apologize :(

Answer:

531 cm^2  approx

Step-by-step explanation:

Given data

Diameter= 26 cm

radius= d/2= 26/2= 13 cm

Area= πr^2

substitute

A= 3.142*13^2

A= 3.142*169

A= 530.998

A= 531 cm^2  approx

Answer:

x = 5

Step-by-step explanation:

The sum of the angles of a triangle is 180°.

(180 - 18x + 5) + (-1 + 8x) + 46 = 180

⇒ 180 - 18x + 5 - 1 + 8x + 46 = 180

⇒ -10x + 230 = 180

⇒ -10x = -50

⇒ x = 5

Answer:

x^4 - 16x^3 + 96x^2 -256x + 256

Step-by-step explanation:

The coefficients of this using the pascal triangle is ;

1 4 6 4 1

Thus, we have that;

1(x^4•(-4)^0) + 4(x^3)(-4)^1 + 6(x^2)(-4^2) + 4(x^1)(-4)^3 + 1(x^0)(-4)^4

= x^4 - 16x^3 + 96x^2 -256x + 256

Answer:

Sin A = 0.38462

Step-by-step explanation:

From the trigonometric function,

Sin A = [tex]\frac{Opposite}{Hypotenuse}[/tex]  ................... 1

So that, applying the Pythagoras theorem to determine the value of hypotenuse,

[tex]/Hyp/^{2}[/tex] = [tex]/Opp/^{2}[/tex] + [tex]/Adj/^{2}[/tex]

            = [tex]24^{2}[/tex] + [tex]10^{2}[/tex]

            = 576 + 100

[tex]/Hyp/^{2}[/tex] = 676

Hyp = [tex]\sqrt{676}[/tex]

       = 26

The hypotenuse of the triangle is 26.

Thus, from equation 1;

Sin A = [tex]\frac{10}{26}[/tex]

Sin A = 0.38462

Answer:

1. complementary

2. not complementary or supplementary

3. not complementary or supplementary

4. complementary

5. supplementary

Step-by-step explanation:

You can tell if two angles are complementary if their combined angle values add up to 90 degrees

[tex]A+B=90[/tex]

You can tell if two angles are supplementary if their combined angle values add up to 180 degrees

[tex]A+B=180[/tex]

If they don't add up to these values then they are neither complementary nor supplementary

[tex]A+B\neq 90[/tex]        [tex]A+B\neq 180[/tex]

plz mark me brainliest. :)

Answer:

2 1/6 berries

Step-by-step explanation:

Sam has 2 1/2 pounds of blueberries. Ben also has some blue berries. Together, they have 4 2/3 pounds of blueberries

Total number of berries = Number did berries Sam has + Number of Berries Ben had

The number of berries Ben had =

4 2/3 - 2 1/2

2 ( 4 - 3/6)

2 1/6 berries

Answer:

0.5

Step-by-step explanation:

6 is half of the tiles

Answer:

We have been given that a car can travel 476 miles on 14 gallons of gas and we are asked to write an equation relating the distance d to the number of gallons g.

We can set an equation as distance traveled is directly proportional to number of gallons used in travelling that distance.

Now we will find out K(number of miles traveled in one gallon of gas) by substituting our given values in this equation.

Therefore, we can see that car travels 34 miles in one gallon of gas.

Now we can use this information to find out how many gallons of gas does this car need to travel 578 miles.

Let us divide number of miles to be traveled by number of miles traveled in one gallon of gas to find out number of gallons of gas needed.

Therefore, car need 17 gallons of gas to travel 578 miles.

Step-by-step explanation:

Step-by-step explanation:

476=14

578=X

578*14/476

8092/476=17

So the answer is 17 gallons

the answer is 150

Answer:

135

E = - 14.5t + 135

Step-by-step explanation:

Given that, descent rate is constant ;

Elevation after 2 days = 106 m

Elevation after 6 days = 48 m

Let

Rate of elevation per day= x

Initial elevation = a

Hence,

a - 2x = 106 - - - (1)

a - 6x = 48 ___(2)

-2x + 6x = 106 - 48

4x = 58

x = 58/4

x = 14.5 meters per day

Hence, initial elevation :

a - 2(14.5) = 106

a - 29 = 106

a = 106 + 29

a = 135

Relationship between Rover's elevation, E and elapsed time, t

E = - 14.5t + 135

-14.5 = rate per day
