Explanation:
Focus on triangle ABC. Let's find the missing angle
A+B+C = 180
113+B+22 = 180
B+135 = 180
B = 180-135
B = 45
Between the triangles, have two pairs of angles that are congruent
A = D = 113
B = E = 45
Which is enough to prove the triangles are similar through the angle angle (AA) similarity theorem. This must mean that C = F = 22
Since we have A pair with D, and B pair with E, this means that [tex]\triangle ABC \sim \triangle DE F[/tex]
The order of the letters is important so we know how the angles pair up. The first letters pair up together, the second letters pair up, and so on.
Consequently, this means sides BC and EF pair up and AC and DF pair up
We can then say...
BC/EF = AC/DF
18/12 = x/4
18*4 = 12*x
72 = 12x
12x = 72
x = 72/12
x = 6
AC = 6

Say a certain manufacturing industry has 63.1 thousand jobs in 2008, but is expected to decline at an average annual rate of 1.7 thousand jobs per year from 2008 to 2018. Assuming this holds true, what will be this industry’s percent change from 2008 to 2018?
a.
70%
b.
-27%
c.
-17%
d.
-75%
Please select the best answer from the choices provided
A
B
C
D
Answers
Answer:
The answer is B!
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 63000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 63000, so we can write it down as 100%=63000.
4. We know, that x% equals 17000 of the output value, so we can write it down as x%=17000.
5. Now we have two simple equations:
1) 100%=63000
2) x%=17000
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=63000/17000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 17000 is what percent of 63000
100%/x%=63000/17000
(100/x)*x=(63000/17000)*x - we multiply both sides of the equation by x
100=3.7058823529412*x - we divide both sides of the equation by (3.7058823529412) to get x
100/3.7058823529412=x
26.984126984127=x
x=26.984126984127
now we have:
17000 is 27% of 63000

-27%

Given the above equation, what is the value of
10-[(a -3) - 7]?
Answers
Answer:
10
Step-by-step explanation:
a=3+7
a=10
10-[(10-3)-7]=
=10-[7-7]=
=10-0=
=10
The solution of expression 10 - [(a - 3) - 7] would be 10.
Given that,
The equation is,
-7 + a = 3
Now, we can simplify the equation as,
- 7 + a = 3
a - 7 = 3
Subtract 3 on both sides,
a - 3 - 7 = 0
(a - 3) - 7 = 0 .. (i)
Here, the equation to simplify is,
10 - [(a - 3) - 7]
Substitute the value from equation (i),
10 - 0
= 10
Therefore, the solution of expression is 10.

DEF is a right traingle if the three sides are 24 40 and 17
Answers
If it is, then the squares of the short side and the medium side add up to the square of the longest side.
Let's check it out:
Square of the short side = 17² = 289
Square of the medium side = 24² = 576
These two squares add up to (289 + 576) = 865
Square of the longest side = 40² = 1,600
865 is not equal to 1,600.
So these three numbers do not make a right triangle.

The width of the television will be 23 inches. Then the correct option is A.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
The length of a rectangular television is 3 inches longer than its width. The display has a 144-inch perimeter. Then the equation is given below.
L = 2W + 3 ...1
144 = 2(L + W) ...2
From equations 1 and 2, then have
144 = 2(2W + 3 + W)
72 = 3W + 3
3W = 69
W = 23 inches
The width of the television will be 23 inches. Then the correct option is A.
