Answer:

The steepness of any incline can be measured as the ratio of the vertical change to the horizontal change. For example, a  5 % incline can be written as  5100 , which means that for every  100  feet forward, the height increases  5  feet.Figure  4.4.1 In mathematics incline of a line the slope and use the letter  m  to denote it. The vertical change is called the rise and the horizontal change is called the run.Slopem=vertical changehorizontal change=riserun(4.4.1)The rise and the run can be positive or negative. A positive rise corresponds to a vertical change up and a negative rise corresponds to a vertical change down. A positive run denotes a horizontal change to the right and a negative run corresponds to a horizontal change to the left. Given the graph, we can calculate the slope by determining the vertical and horizontal changes between any two points.Example  4.4.1 Figure  4.4.2 From the given points on the graph, count  3  units down and  4  units right.m=riserun=−3units4units=−34 the Answer is.m=−34 .

Step-by-step explanation:

I solved this.

Answer:

[tex]-\frac{35}{18}[/tex]

Step-by-step explanation:

[tex]\frac{5}{3}[/tex] ÷ [tex]-\frac{6}{7}[/tex] is the same as [tex]\frac{5}{3}[/tex] × [tex]-\frac{7}{6}[/tex]

Multiply across:

5 x 7 = 35

3 x 6 = 18

Applying the negative sign, we get:

[tex]-\frac{35}{18}[/tex]

Since we cannot simplify any further, -35/18 is out final answer.

Answer:

Option A, [tex]385.0\ ft^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the base

[tex]A = l * w[/tex]

[tex]A = 11\ ft * 11\ ft[/tex]

[tex]A = 121\ ft^2[/tex]

Step 2:  Determine the area of the triangles

[tex]A = \frac{h * b}{2}[/tex]

[tex]A = \frac{12\ ft * (11\ ft / 2)}{2}[/tex]

[tex]A = \frac{12\ ft * 5.5\ ft}{2}[/tex]

[tex]A = \frac{66\ ft^2}{2}[/tex]

[tex]A = 33\ ft^2[/tex]

There are two of these triangles per side which means that there are 8 of these triangles in total.  

[tex]33\ ft^2 * 8[/tex]

[tex]264\ ft^2[/tex]

Step 3:  Determine the surface area

[tex]SA = 121\ ft^2 + 264\ ft^2[/tex]

[tex]SA = 385\ ft^2[/tex]

Answer: Option A, [tex]385.0\ ft^2[/tex]

Answer:

0.571428571429 grams per cm³

Step-by-step explanation:

density = mass/volume

Let’s calculate the volume V of the pyramid :

V = (1/3)×base×height

   = (1÷3)×(5×7)×9

   = 105 cm³

Then

The density = mass/volume

                    = 60÷105

                    = 0.571428571429

The center of the circle must be on the perpendicular bisector of chord PQ since it passes through the center.

It should be noted that a perpendicular bisector simply means a line the intersect another line through the intersection point.

In this case, the center of the circle must be on the perpendicular bisector of chord PQ since it passes through the center. This bisects it at a right angle. The chord closer to the centimeter will be the one closer to the diameter.

Answer:

The answer is 4cm.

Step-by-step explanation:

Given:

Height= 15cm

The volume of the Cylindrical bottle= 753.6

They have said to use π= 3.14

We are supposed to find r.

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

Volume of cylinder= πr²h

now substitute teh values given in the formula..we will get:

753.6 = 3.14× r²× 15

After u solve it , you will get

r²= 16

∴r = √16= 4cm

So,  the radius of the bottle is 4cm

Step-by-step explanation:

Area750 cm² = 750 × 10^-4 m²

pressure = F/A

= 61 /(750×10^-4)

= 61 × 10⁴/750

= 0.081 × 10⁴

= 810 N/ m²

Answer:

813N/m^2

Step-by-step explanation:

Pressure is defined as the amount of force applied to an area. There are 100cm in a single meter, therefore:

[tex]750cm^2=\sqrt{750} cm\frac{1}{100} \frac{m}{cm} =\frac{\sqrt{750} }{100} m=0.075m^2[/tex]

Pressure formula is:

Answer:

25.7 m

Step-by-step explanation:

Semicircles are half circles that are divided at the diameter.

We want to find the semicircle arc.

To do this, just find the circumference of the circle and then divide by 2.

Circumference formula:

2rπ or Dπ

10π = 31.4

31.4 / 2 = 15.7

Now, we have to find the straight line part of the semicircle. The length of that straight line is the diameter. We already know that the diameter is 10.

Add

15.7+10 = 25.7

Now isolate 'w'

[tex]\sf w = 15 +\dfrac{19}{2}\\\\= \dfrac{15*2}{1*2}+\dfrac{19}{2}\\\\=\dfrac{30}{2}+\dfrac{19}{2}\\\\=\dfrac{30+19}{2}\\\\=\dfrac{49}{2}\\\\= 24\dfrac{1}{2}[/tex]

Answer:

  (b)  Length = 30 feet, width = 20 feet

Step-by-step explanation:

The scale factor is applied to the drawing dimensions to find the actual dimensions.

__

  length = (6 cm) × (5 ft)/(1 cm) = 30 ft

  width = (4 cm) × (5 ft)/(1 cm) = 20 ft

_____

Additional comment

You can also write the scale factor as part of a proportion:

  5 ft : 1 cm :: x ft : 6 cm

Multiplying by 6 cm gives

  (5 ft)(6 cm)/(1 cm) = x ft = 30 ft . . . . as above

Answer:

21.875%

Step-by-step explanation:

We need an equation to represent this problem,

Let x be the number of books she had before giving away 42 of them,

x - 42 = 150

To find out how many books she had before turn the problem around and add 42 with 150,

150 + 42 = x

⇒ x = 192

Now that you know that divide 42 by 192,

Let n be the quotient of 42/192

42/192 = n

⇒ n = 0.21875

Now to turn that into a percent move the decimal 2 spaces to the left,

0.21875

⇒ 2.1875

⇒ 21.875%

Therefore there was a 21.875% change.
