Step-by-step explanation:

Bob's linear speed is higher than Jack's because the radius of the circle

around which Bob rotates is larger.

Responses:

Given:

The rotational speed of the merry go round = 6 revolution per minute

Jack's distance from the center = 10 feet

Bob's distance from the center = 14 feet

The angular speed, ω, of the merry-go-round is found as follows;

Answer:

y = -1x + 2

Step-by-step explanation:

We need to find y = mx + b

Use the following equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Plug in the values

[tex]\frac{-1-0}{3-2}[/tex]  = [tex]\frac{-1}{1} = -1[/tex]

We have found the slope(m) which is -1

We have to find y-int b

Plug in any given x,y into the slope formula

-1 = -1(3) + b

-1 = -3 + b

2 = b

At last the formula is

y = -1x + 2

Answer:

yearly cost for housing expenses = $11,400, average monthly cost for food = $650

yearly clothing cost = $900,

average monthly cost for transportation= $500,

Yearly cost for insurance & medical= $14,400

yearly cost for emergency fund = $600

average monthly college saving = $50

Step-by-step explanation:

Yearly housing = monthly cost * 12 = 950 * 12 = 11400

Food, monthly = 7800 /12 = 650

Clothing, yearly = 75 * 12 = $900

Monthly transport = 6000 / 12 = $500

Insurance and medical = 1200*12 =14400

Emergency fund = $50 * 12 = $600

College saving = $600 / 12 = $50

Answer:

a There are n-3 diagonals from each vertex.

b The diagonals from each vertex divide the polygon into n-2 triangles.

c In a regular polygon with n sides, each angle measures (n-2)180/n degrees.

Step-by-step explanation:

You can check to see which answers are true for a 3-sided or 4-sided regular polygon (a triangle or square).

  triangle: 3 sides, 0 diagonals, 1 triangle 60-degree angles

  square: 4 sides, 1 diagonal, 2 triangles, 90-degree angles

The statements that are true for our test cases are ...

  a There are n-3 diagonals from each vertex.

  b The diagonals from each vertex divide the polygon into n-2 triangles.

  c In a regular polygon with n sides, each angle measures (n-2)180/n degrees.

Answer:

  31 and 72

Step-by-step explanation:

Let x be the smaller number and y be the larger number. Then we have ...

  x + y = 103 . . . . . sum is 103

  y = 2x +10 . . . . . y/x is 2 remainder 10

Substituting for y, we get ...

  x + (2x +10) = 103

  3x = 93

  x = 31

  y = 103 -31 = 72

The two numbers are 31 and 72.

Answer:

40

the

answer

is

40

Answer:

The 30% of a number can be calculated multiplying that number by 0.3, so, if we call the number we don't know x, we can write this equation:

0.3x = 12

And then solve it for x::

x = 12/0.3 = 40

So now we know that the number is 40.

We can replace the 40 in the equation to get if our answer is correct or not..

30% of 40: 0.3 *  40 = 12

And then, we see it's correct

Answer:

y > 1/3 x - 3

Step-by-step explanation:

First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).

Find the change of y over the change of x to get the slope of the line.

(-2 - (-3))/(3 - 0) = 1/3

Since the line intercepts the y axis at (0, -3), the equation of the line would be

y = 1/3x - 3

We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents

y > 1/3 x - 3

Answer:

density = 0.0087 kg/cm³

Step-by-step explanation:

density = mass/volume

= 3.48/400 = 0.0087 kg/cm³

answer will be -24

A=-24

Answer:

A = 36

Step-by-step explanation:

Using the cofunction identity

tan(90 - x) = cotx

Given

tan2A = cot(A - 18) , then

90 - 2A = A - 18 ( add 2A to both sides )

90 = 3A - 18 ( add 18 to both sides )

108 = 3A ( divide both sides by 3 )

36 = A
