Find the length of MN.
*LOOK AT PICTURE*
Answer:
MN = 10
Step-by-step explanation:
There is a scale factor of 2 [This means that the lengths of triangle ∆MPN are exactly 2 times larger than ∆SRQ], so 5 × 2 = 10.
Notice that each corresponding line is marked by a black mark perpendicular to the side. Since 2 corresponds to 4, and 3 corresponds to 6, 5 must correspond to 10. These triangles are similar as indicated by the marks so there is just a size difference. Because these two triangles are similar, the sides must be proportional.
∆MPN ~ ∆SRQ.
It can also be thought of as completing a set of proportional fractions:
4/2 = 6/3 = ?/5
4/2 = 2 → 6/3 = 2 → ?/5 = 2.
?/5 = 2, ? = 5 × 2 = 10.

I took the test.
On the first night, the Movie House Theater sold 7 adult tickets and 11 child tickets for
$227. On the second night they took in $150 by selling 6 adult tickets and 6 child tickets.
Find the price of an adult ticket and the price of a child ticket.
Answer:
Adults $10
Child: $6
Step-by-step explanation:
I took the test
The price of an adult ticket and the price of a child ticket are $12 and $13.
What is the system of equation?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
On the first night,
the Movie House Theater sold 7 adult tickets and 11 child tickets for $227.
On the second night, they took in $150 by selling 6 adult tickets and 6 child tickets.
Let x be the number of tickets sold to an adult and y be the number of tickets sold to a child.
According to the question,
7x + 11y = 227 equation 1
and 6x + 6y = 150,
Simplifying,
x + y = 25 equation 2
Now, we have a system of equations.
7x + 11y = 227 equation 1
x + y = 25 equation 2
From the equation 2 we have,
y = 25 - x
Substitute the value of y to the equation 1,
7x + 11(25-x) = 227
7x + 275 - 11x = 227
275 - 227 = 4x
x = 48/4
x = 12
Then y = 25 - 12
y = 13.
Therefore, the prices of ticket for adult's and children are $12 and $13 respectively.

i need to know where to graph it too
Step-by-step explanation:
y=2x+3
y=3x+3
(Use the elimination method)
y=2x+3(-3) = -6x-9
y=3x+3(2) = 6x+6
(subtract the new equations)
y= -3
(Now find X)
(plug in y in any equation and solve)
y=2x+3
(-3)=2x+3
0= 2x X= 0
or you can just graph the lines go to three on the Y axis put a point go up the y-axis two and over 1 and plot another point.
go to three on the y-axis and plot a point. go up three on the y-axis and over 1

Is “12.95 x 10^4” a Scientific Notation? Yes or No? Explain.
Answer:
Yes
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8. and that is something Very similar.

Answer:
the answer is BE
Step-by-step explanation:
skews are lines that dont intersect or arent parallel to each other
in that case BE or CF are correct but BE is the only answer choice that works... hope it works
The line segment skew to GH is BE.
What are skew line segments?Skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron.
Given is a rectangular prism, with vertices, A, B, C, D, E, F, G and H
We are asked to identify a line segment which is skew to GH,
In the given options, EF, AD are BC are parallel to GH hence not skew, but line segment BE is neither parallel nor perpendicular to GH.
Hence, the line segment skew to GH is BE.

Expo Milano 2015 was visited by 22.2 million people. It is expected that Expo 2020 Dubai will
be visited by 25 million people. Find the percent of change.
Answer:
12.6% is the percent of change.
Step-by-step explanation:
As Expo Milano 2015 was visited by 22.2 million people.
And it is expected that Expo 2020 Dubai will be visited by 25 million people.
so
25 - 22.2 = 2.8 million people
so dividing the 2.8 by 22.2 would give us the percentage of increase.
2.8/22.2 = 0.126 which is = 12.6%
Therefore, 12,6% is the percent of change.

22, 24, 27, 28, 30
22, 24.5, 26, 28, 30
Given:
The data values are 22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30.
To find:

Now,
Minimum value = 22
[tex]Q_1=\dfrac{24+25}{2}=24.5[/tex]
Median = 26
[tex]Q_2=\dfrac{28+28}{2}=28[/tex]
