Explanation:
Focus on the outer ring of numbers only.
The left arm of the angle points at 140. The right arm points at 15. The difference of which is 140-15 = 125
---------------
Alternatively, focus on the inner ring of numbers only.
The left arm points at 40 and the right arm points at 165.
165-40 = 125
We get the same answer as before.

Find the coordinates of B, C, and D given that AB=5 and BC = 10
Answers
Answer:
B = (3, -5)
D = (0, -1)
C = (3, 5)
Step-by-step explanation:
We want to find the coordinates of B, C, and D given that AB = 5 and BC = 10.
Because AB = 5 and BC = 10, we can find the slope of the line using the slope formula:
[tex]\displaystyle \begin{aligned} m & = \frac{\Delta y}{\Delta x} \\ \\ & = \frac{(10)}{(5)} \\ \\ & = 2 \end{aligned}[/tex]
Point A(-2,-5) is on the line. Hence, the equation of the line is:
[tex]\displaystyle \begin{aligned} y-y_1 &= m(x-x_1) \\ \\& = y-(-5) = 2(x-(-2)) \\ \\ y + 5 & = 2x+4 \\ \\ y & = 2x-1 \end{aligned}[/tex]
Because AB is 5, B is simply A shifted rightwards five units. Hence:
[tex]\displaystyle B = (-2+5, -5) = (3, -5)[/tex]
At Point D, x = 0. Hence:
[tex]\displaystyle y = 2(0) -1 = -1[/tex]
Thus, D is at (0, -1).
B and C are collinear. Hence, the x value of C is 3:
[tex]\displaystyle y = 3(2) - 1 = 5[/tex]
Therefore, C is at (3, 5).
Estimate 1 3/4+4 7/8 to the nearest whole number.

Write an equation for the sentence below.
The sum of three times a number (x) and -23−23 is 2828.
Answers
Answer:
3x - 23 = 2828
Step-by-step explanation:
I'll assume the question is supposed to read "The sum of three times a number (x) and −23 is 2828."
"three times a number (x)" can be written as 3x
"sum of three times a number (x) and −23" means 3x - 23
"is 2828" = 2828
Put them together:
3x - 23 = 2828

Using proportions, it is found that 8 more seventh graders are involved in the yearbook.
What is a proportion?A proportion is a fraction of a total amount.
Researching the problem on the internet, it is found that 10% of the 6th graders and 18% of the 7th graders are on the yearbook, hence:
0.1 x 280 = 28 6th graders.
0.18 x 200 = 36 7th graders.

Which is a factor of x2 – 9x 14? x – 9 x – 2 x 5 x 7.
Answers
Answer:
Step-by-step explanation:
The 2 factors of x^2 - 9x + 14 are (x - 7) and (x - 2) because -7 + -2 = -9 and -7 x -2 = 14.
The factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2) option (B) (x - 2) is correct.
What is a quadratic function?Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.
It is given that:
The quadratic expression is:
= x² – 9x + 14
Using factor method:
= x² – 7x - 2x + 14
= x(x - 7) - 2(x - 7)
= (x - 7)(x - 2)
The factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2)
Thus, the factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

In Figure 1 :- In figure 1 , we have given everything we don't need to determine anything in figure 1 In Figure 2 :- Here, we have to determine the measure of sides ,braces and angles with least number of known measures,Let's start ,
From the figure, we can assume the beam forms as AD, BC, EF , GH and so on.
Therefore,
[tex]\sf{ ABCD , AEFD, AGHD.. so \:on similar\: to \:each \:other }[/tex]
So,
[tex]\sf{ Angle\:BAD = Angle\:EBC = Angle\:GEF}[/tex]
Or,
[tex]\sf{ Angle\: ADC = Angle\:BCF = Angle\: EFH }[/tex]
Now, By using similarity theorem we can determine their sizes, braces and angles that is,
[tex]\sf{\red{ AD/BC = AB/AE = CD/CF = BC/EF}}[/tex]
[tex]\bold{\huge{\blue{\underline{Answers :- }}}}[/tex]
Answer 1 :-
For answering the above questions we use knowledge and practices regarding the questions we can do the activity by making figures of unknown sides by assuming it in the form of x, y.so that we can find the known values.
Answer 2 :-
The best way of solving the above questions is that it is already given in the question that the beam is symmetrical so, here we can use similarity theorem.
Answer 3 :-

Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{MO}{PR}[/tex] = [tex]\frac{MN}{PQ}[/tex] ( substitute values )
[tex]\frac{4+x}{5}[/tex] = [tex]\frac{x-2}{2}[/tex] ( cross- multiply )
5(x - 2) = 2(4 + x) ← distribute parenthesis on both sides
5x - 10 = 8 + 2x ( subtract 2x from both sides )
3x - 10 = 8 ( add 10 to both sides )
3x = 18 ( divide both sides by 3 )
x = 6

A wire 90 cm long is cut into two pieces. One

long is the shorter piece of wire?
Answers
Answer:
30 cm
Step-by-step explanation:
30+60=90
30×2=60 so 30cm is the answer.
Step-by-step explanation:
If one price is 2 times the other one, that means it's equal to 2 of those parts. Let's decide our total wire by three to account for the larger part.
[tex]90 \div 3 = 30[/tex]
Now we know the shorter piece is 30 cm. To find the longer piece, multiply the shorter piece by 2.
[tex]30 \times 2 = 60[/tex]

Shorter Piece: 30 cm
Longer Piece: 60 cm

Answers
Answer:
Equation: y = 2x + 25
Step-by-step explanation:
Here x determines the number of year. For the first year,we will see ( 2 * 1 ) = $2 increase. In the second year, ( 2 * 2 ) =$4 increase and like this goes on, whereas the $25 being constant. "y" determines the total cost for each year.
Therefore the equation can be made: y = 2x + 25

The transport charge starts with a minimum charge of R8 and thereafter it was increased by R2 for each kilometre. On a particular day the bus was full with passengers from Butterworth. In each and every kilometre there was a passenger getting off while no new passenger entered in the bus. Mr Dlamini was calculating total money in his hand after each passenger was getting out. The total amount he has after each stop can be written as a series as follows: S. = 8 + 10 + 12 + 14 +... Use the series to calculate the following questions 1.1 (1) Term 2 (T2) = Sum of first two terms (S2) (2) (ii) Express T2 in terms of S, and S2. (1)

From the series, it can be deduced that the sum of the first two terms will be 18.
How to calculate the seriesFrom the information given, it was stated that the transport charge starts with a minimum charge of R8 and thereafter it was increased by R2 for each kilometre.
The series is also given as S. = 8 + 10 + 12 + 14 +... Therefore, the sum of the first two terms will be:
= 8 + 10
= 18
