Louis makes a model of a plane.
The wingspan of the model is 50 centimetres.
The wingspan of the real plane is 80 metres.
Work out the scale of the model.
Give your answer in the form 1:n
Answers
Answer:
1 : 1.6
For every centimeter on the model, it is 11.6 centimeters on the real plane
Step-by-step explanation:
The required value of the scale of the model in the form of 1:160.
Given that,
The wingspan of the model is 50 centimeter,
The wingspan of the real plane is 80 meter.
We have to determine,
The scale of the model and give your answer in the form 1 : n.
According to the question,
The wingspan of the model = 50 centimeter [tex]= \frac{50}{100} = 0.5m[/tex]
The wingspan of the real plane is 80 meter.
The ratio of the scale = 1:n
Therefore,
The equation of proportion is,
[tex]\frac{wingspan \ of \ the \ model}{wingspan\ of \ the \ palne} = \frac{1}{n}[/tex]
Putting all the values in the equation,
[tex]\frac{0.5}{80} = \frac{1}{n} \\\\n = \frac{1 \times 80}{0.5} \\\\n = 160[/tex]
The value of n = 160.
Hence, The required value of the scale of the model in the form of 1:160.

A triangle has a base of 18.1 kilometres and a height of 17.4 kilometres. What is the area?
Answers
Answer:
157.47km²
Step-by-step explanation:
Given the following
base of 18.1 kilometres
height of 17.4 kilometres
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * 18.1 * 17.4
Area of the triangle = 314.94/2
Area of the triangle = 157.47km²
Hence the area of the triangle is 157.47km²

Write a situation about today's sales for the following systems of equations and then determine how much of each menu item you sold e + f = 48 and e = 3f
Answers
Answer:
3x48+48 = 192
3x48= 144
144+48= 192
There has been sold 12 items of f and 36 items of e in the system.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We are Given the system of equation:
(1) e + f = 48
(2) e = 3f
Then Substituting e=3f into e + f=48:
3f + f = 48
Adding similar terms:
4f = 48
Dividing both sides by 4:
f = 48/4
Simplifying:
f = 12
Replacing;
f=12 in e + f =48
e + 12 = 48
Now Subtracting -12 to both sides:
e = 48 - 12
e = 36
Thus There has been sold 12 items of f and 36 items of e.

how I find the slope it by looking at the y-axis and what hits directly on that line. you can see that 3 hits directly on that line so the b in y=mx+b is three which is your starting point. then you follow the line and see where it hits directly on a point. then count the blocks. remember that it's rise over run so that's y over x. so you go down five and over one. since you go down five it's negative. the negative is only added onto the five not the one. and since it's five over one, you don't need to put the over one, it's just automatically there. hope this helps! good luck!

Answer:

Step-by-step explanation:

The volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.
What is a right square pyramid?In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the squares joints at the top which is perpendicular to the center of the square.
We know volume for the right square pyramid is given by:
[tex]\rm V= \frac{1}{3} b\times h[/tex]
Volume for the cut off portion:
[tex]\rm v = \dfrac{1}{3}\times16\times16\times12[/tex]
v = 1024 cubic meters
Volume for the completer pyramid"
[tex]\rm V=\dfrac{1}{3}\times64\times64\times48[/tex]
V = 65536 cubic meters
Volume of the building = 65536 - 1024
= 64512 cubic meters
Thus, the volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.

That’s because in radicals if there’s a square inside they square root that and put it on the outside. For example for √8, it would be 2√2, since the four can be square rooted, and there is still a 2 left inside the square root. For √48, there is a sixteen inside so you square root the 16 and get 4√3.

Answers
Answer:
C. y </ 3/4x +10 and y<l -1/2x - 3
Step-by-step explanation:
Basically first do process of elimination with your focus on one equation
for example :: ( >l is greater then or equal to and <l is lease then or equal to)
focus -> y >l 3/4x + 10
1) determine which line has the y-intercept of positive 10
2) is the line dotted or straight? dotted line = > or < while straight line = >l or <l
this should get rid of B and D now
3) remember this = if the slope is - then the shaded portion would be the way that the less then sign is pointing
( y <l -4x then the shaded portion would be on the left side )
remember again = if the slope is + then the shaded portion would be the way that the greater then sign is pointing
( y <l 4x then the shaded portion would be on the right side )
so the line that we are focused on would have the right side shaded which means that it would be a <l ,so the answer would be C
