Answer:

Question 1:  Slope = \frac{1}{3}  feet

Question 2:  Slope = 4

Step-by-step explanation:

Question 1:

The pitch of a roof is the inclination of that roof. The "slopiness" of the roof. Whether it is steep or not.

To know the pitch, we need to find the "RISE" over "RUN". That means the "height" from ground and the "length" from initial position.

The height is shown in the figure as 4 ft

The length is shown in the figure as 12 ft

The slope is the quotient of it.

Hence,

Slope = 4/12 = 1/3 feet

Question 2:

To find slope from table of points, we need 2 coordinate pairs in the form (x,y). Lets take the first two points.

(1,2)

and

(3,10)

The slope would be the change in y coordinates of both (2nd point y coordinate - 1st point y coordinate) DIVIDED by the change in x coordinates of both (2nd point x coordinate - 1st point x coordinate). So:

Change in y coordinates = 10 - 2 = 8

Change in x coordinates = 3 - 1 = 2

Thus,

Slope = change in y/change in x = 8/2 = 4

Slope = 4

How do you use the triangle sum theorem to find the measure of each angle in degrees ?!
TEA [102]

Answer:

The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.

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

Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°

Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)

Ask in the comments below if you are not sure about something.

I hope that helps you! :D

A cube whose edge is 20 cm 1 point
Sav [38]

Answer:

Unpainted  surface area = 514.28 cm²

Step-by-step explanation:

Given:

Side of cube = 20 Cm

Radius of circle = 20 / 2 = 10 Cm

Find:

Unpainted  surface area

Computation:

Unpainted  surface area = Surface area of cube - 6(Area of circle)

Unpainted  surface area = 6a² - 6[πr²]

Unpainted  surface area = 6[a² - πr²]

Unpainted  surface area = 6[20² - π10²]

Unpainted  surface area = 6[400 - 314.285714]

Unpainted  surface area = 514.28 cm²

A music club has 35 drum players. If 25% of the total number of members in the club are drum players, what is the total number o
Pachacha [2.7K]

Answer:

140

Step-by-step explanation:

Since 25% is 1/4 of 100, that means that 35 is 1/4 of the total amount of members in the club. So, 35 times 4 is 140.

4x9(yellow)=36
36+8=44
basically 8 gallons of red
i hope this made sense
