Answer:
8
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle
7x - 4 + 9x + 4 = 128° add like terms
16x = 128 divide both sides by 16
x = 8
A ramp must be in the form of a right triangle where every vertical length(leg) of 1 ft has a horizontal length(leg) of 12 ft. What is the length of a ramp with an 18-ft horizontal leg and a 1.5-ft vertical leg? Round your answer to two decimal places.

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.
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.
Hope this helps!

I think in order to solve this, you would need to add up the fractions that they used. So it would be,
[tex]\frac{1}{4}+\frac{1}{4}+\frac{3}{8}+\frac{3}{8}+\frac{5}{8}+\frac{5}{8}+\frac{5}{8}+\frac{7}{8}[/tex] Transform the Expressions
[tex]\frac{1+1}{4} +\frac{3+3+5+5+5+7}{8}[/tex] Calculate the sum
[tex]\frac{2}{4} +\frac{28}{8}[/tex] Reduce
[tex]\frac{1}{2}+\frac{7}{2}[/tex] Transform the Expression
[tex]\frac{1+7}{2}[/tex] Calculate
[tex]\frac{8}{2}[/tex] Reduce the Fraction
[tex]4[/tex]

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.

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

What is the value of x? Please provide an explanation, thanks!
Answer:
x=97/5Step-by-step explanation:
let y be the opposite angle,
6x-11 + y = 180( sum of opposite angles)
y=180+11-6x
y=191 - 6x
thus, 81+x+5+191-6x=180(angle sum property)
-5x=-97
x=97/5Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answer:
26
Step-by-step explanation:
Let D =Devaughn's age
S= Sydney's age
So D+S=64
D=S+12
Now
D+S=64⇒D=64−S
and so
S+12=64−S 2S=52
S=26
Therefore
D=S+12
D=38

The stemplot below displays the times, in seconds, for 25 students to run 100 meters.
A stemplot titled 100 meter times (seconds) has values 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.
Which of the following is the correct five-number summary?
22, 24, 26, 28, 29
23, 24.5, 26, 28, 29
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:
The five-number summary.
Solution:
We have,
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
Divide the data values on 2 equal parts.
(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)
Divide each parentheses in two equal parts.
(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)
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]
Maximum value = 30
So, the five number summary is 22, 24.5, 26, 28, 30.
Therefore, the correct option is D.
