Answer: 13 packages.

Step-by-step explanation:

This can be translated to:

Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all the headphones and music players in identical packages. What is the largest number of packages that Tim can do?

To solve this we must find the largest common factor between 39 and 13.

to do this, we divide the smaller number by different integers, and see if the result also divides the larger number into an integer.

13/1 =13 and 39/13 = 3

So 13 is the largest common factor.

This means that we can make 13 packages, each with:

39/13= 3 headphones

13/13 = 1 music players

Answer:

9 sides

Step-by-step explanation:

Two methods and the same answer = 9 sides

Method 1: Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.

Method 2: Since the exterior angle 140 degrees, The sum of the interior angles = (2n - 4)* right angles. So 140n =(2n - 4)* right angles, or

140n =(2n - 4)*90, or

140n = 180n - 360, or

40n = 360, or

n = 9 sides.

Hence the number of sides is 9 sides.

Answer:

9

Step-by-step explanation:

The sum of the interior angle and the exterior angle = 180°

Thus the exterior angle of the polygon = 180° - 140° = 40°

The sum of the exterior angles of a polygon = 360°, thus

number of sides = 360° ÷ 40° = 9

Answer:

CD = 12.

Step-by-step explanation:

By the tangent-secant theorem:

AB^2 = AC * AD

8^2 = 4 * AD

AD = 64/4 = 16

Finally CD = AD - 4 = 12.

Answer:

Step-by-step explanation:

area = pi*radius*radius -> Radius =  [tex]\sqrt{\frac{area}{pi} }[/tex]

area: 63.585 m2

   -> radius = [tex]\sqrt{\frac{63.585}{3.14} }[/tex] = 4.5 m

area: 28.26m2

  -> radius = [tex]\sqrt{\frac{28.26}{3.14} }[/tex] = 3m

   -> diameter = 6m

area: 120.7016m2

  -> radius = [tex]\sqrt{\frac{120.7016}{3.14} }[/tex] = 6.2m

   -> diameter = 12.4m

area: 12.56m2

   -> radius = [tex]\sqrt{\frac{12.56}{3.14} }[/tex] = 2m

area: 482.8064m2

   ->radius = [tex]\sqrt{\frac{482.8064}{3.14} }[/tex] = 12.4m

area: 113.04 m2

   ->radius = [tex]\sqrt{\frac{113.04}{3.14} }[/tex] = 6m

Answer:

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

slope is equal to the rate of change, and the equation for it is

change of y divided by change of x

if you were to pick two points of this graph, lets use (-4,-3) and (2,-1), you do the following:

(-4,-3) and (2,-1)

-3-(-1)=-2

(-4,-3) and (2,-1)

-4-2=-6

-2/-6=1/3

Step 1) Divide the figure into shapes

Triangle: 9 x 10

Large rectangle: 8 x 17

Small rectangle: 5 x 9

Smaller rectangle (bottom): 4 x 6

Step 2) Find the area of each shape

Triangle: A = 1/2 x 9 x 10 = 45

Large rectangle: A = 8 x 17 = 136

Small rectangle: A = 5 x 9 = 45

Smaller rectangle (bottom): A = 4 x 6 = 24

Step 3) Add the areas together

A = 45 + 136 + 45 + 24 = 250 square kilometers

Answer:

my answer was -27

Step-by-step explanation:

Answer:

-3

Step-by-step explanation: -2 -17 +12- -4

-2 -17 is -19 since they are both negative. If you add 12 positive to that it becomes -7. Since you are subtracting or taking away -4, think of it as adding 4 instead. This leaves you with -3.

Answer: 5(a+4)

Step-by-step explanation:

An expression that is equivalent to 5a + 20 is: 5 ( a + 4 ).

Since 5 times a equals 5a and 5 times 4 equals 20.

Therefore, 5 (a + 4) is equivalent to 5a + 20.

Where is the equation?

Answer:

D

Step-by-step explanation:

Because the angle with measure 29 degrees and n are a linear pair, their value must add up to 180 degrees. Therefore:

n+29=180

n=180-29

n=151 degrees, or answer choice D

Answer:

|A| - C = 5

Step-by-step explanation:

The maximum value that a sine function can have is 1, and the minimum value is -1.

With this information, to find the minimum value of y, we can use sin(Bx) = -1, and to find the maximum value, we can use sin(Bx) = 1. Then, we have that:

19 = A + C

-5 = -A + C

Summing both equations, we have:

14 = 2C

C = 7

Now, to find the value of A, we can use the first equation:

19 = A + C

19 = A + 7

A = 12

So the value of |A| - C is:

|12| - 7 = 12 - 7 = 5

Answer:

$1.50 per pound

Step-by-step explanation:

got same question and got it right.

The cost per pound of apples is given as $1.50 per pound.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

From the table,

Let the cost of the apples is directly proportional to the pound of x apples,
y = kx

Where k represents the cost of each pound of apply,
From the table consider an ordered pair,
x = 2, y = 3
Now,
3 = 2k
k = 3 / 2
k = 1.5

Thus, the cost per pound of apples is given as $1.50 per pound.
