A property map is drawn at a scale of 1:1000. Calculate the corresponding actual distance if the distance between two points on
zvonat [6]

Answer:10 m

Step-by-step explanation:

Given

Scaling ratio 1:1000

i.e. one unit in map is equal to 1000 unit in actual distance

therefore if the distance between two points is 1 cm in map then

it is 1000 cm in reality

What is the slope of a line parallel to the line y=3x-4=8y+1
Lyrx [107]

Answer:  If the original equation is y = 3x -4,  the slope is 3.

Any equation of a line parallel to the line <u>y = 3x -4</u> will have a slope of 3.

Step-by-step explanation:

In slope-intercept form, y =mx + b the coefficient of x, m is the slope.

Here 3 is that value.

It is very unusual to have two equal signs in a question about slope.

I am not sure what to do with the <u><em>=8y + 1</em></u>

Is this supposed to be another equation in the system, missing a term?

The formula for the volume of a cylinder is V=πr²h.  Substituting the information we have, we get 1470=(3.14)(6²)<span>h
</span>1470=113.04h
Divide both sides by 113.04:
1470/113.04 = 113.04h/113.04
13 ≈ h
The height of the cylinder is 13 inches.  We know that the height of the cone is 1/2 the height of the cylinder; 1/2(13) = 6.5 inches.  The formula for the volume of a cone is:
V=1/3πr²h
The cone and the cylinder have the same radius, and we now know that the height of the cone is 6.5.  Substituting this information in we have:
V=1/3(3.14)(6²)(6.5) = 244.92 in³
The total volume of the cake would be the volume of the cylinder added to the volume of the cone:
1470+244.92 = 1714.92 in³.

The formula for the volume of a sphere, for the ball cake, is 
<em /><em>V</em>=4/3πr³.  Using the radius of 3 we have:
<span><em>V</em>=4/3(3.14)(3</span>³)=113.04 for the volume of the circus ball cake.
The formula for the area of the cone-shaped hat cake is <em>V</em>=1/3π<em>r</em>²<em>h</em>.  We want it to have the same volume as the circus ball cake, and we know the radius is still 3:
<em />113.04=1/3(3.14)(3²)<em>h</em>
This simplifies to
113.04=9.42<em>h</em>
Divide both sides by 9.42:
113.04/9.42 = 9.42<em>h</em>/9.42
The hat cake would have to have a height of 12 inches to have the same volume.

What is the volume of a right circular cone with a diameter of 21 centimeters and a height of 87 centimeters? Use 3.14 as an app
Sindrei [870]
The volume of the cone will be given by:
Volume=1/3πr^2h
therefore the volume of our cone will be:
π=3.14
h=87
r=21/2
Volume=1/3*3.14*(21/2)^2*87
=10,039.365 cm^2
