Interpreting direct variation from a graph

The revolution per foot of travel is 0.2The slope of the graph is 5The revolution per foot of travelFrom the graph, we have the following points
(x.y) = (0,0) and (2,10)
Where:
x represents the number of revolutions
y represents the distance in feet
The revolution per foot of travel (r) is then calculated as:
[tex]r = \frac{x_2 -x_1}{y_2 -y_1}[/tex]
This gives
[tex]r = \frac{2 - 0}{10 - 0}[/tex]
[tex]r = 0.2[/tex]
This means that, the revolution per foot of travel is 0.2
The slope of the graphThis is the reciprocal of the revolution per foot of travel
In (a), we have:
[tex]r = 0.2[/tex]
So, the slope is:
[tex]Slope = \frac 1{0.2}[/tex]
[tex]Slope = 5[/tex]
Hence, the slope of the graph is 5

Chase made a scale drawing of a neighborhood park. The scale of the drawing was 1 millimeter : 8 meters. The volleyball court is 16 meters long in real life. How long is the volleyball court in the drawing?
what millimeters
Answer:
Length of the volleyball court in drawing = 2 mm
Step-by-step explanation:
8 meter = 8 *1000 = 8000 mm
Scale factor = 1 : 8000
Length of the volleyball court in drawing = x
1 : 8000 :: x : 16000
[tex]\dfrac{1}{8000}=\dfrac{x}{16000}\\\\\\\dfrac{1}{8000}*16000=x\\\\[/tex]
x = 2 mm

Question -
If the ratio of the sums of first n^th terms of two AP's is (7n + 1):(4n + 27) find the ratio of their m^th terms.
[tex]\rule{200}4[/tex]
Answer : The required ratio is (14m-6):(8m+23) .
[tex]\rule{200}4[/tex]
Here we are given that the ratio of sum of first n terms of two AP's is (7n + 1):(4n + 27) .
That is.
[tex]\small\sf\longrightarrow \dfrac{S_1}{S_2}=\dfrac{7n +1}{4n +27} \\[/tex]
As , we know that the sum of n terms of an AP is given by ,
[tex]\small\sf\longrightarrow \pink{ S_n =\dfrac{n}{2}[2a +(n-1)d]} \\[/tex]
Assume that ,
First term of 1st AP = a First term of 2nd AP = a'Common difference of 1st AP = dCommon difference of 2nd AP = d'Using this we have ,
[tex]\small\sf\longrightarrow \dfrac{S_1}{S_2}=\dfrac{\dfrac{n}{2}[2a + (n-1)d]}{\dfrac{n}{2}[2a' +(n-1)d'] } \\[/tex]
[tex]\small\sf\longrightarrow \dfrac{7n+1}{4n+27}=\dfrac{2a + (n -1)d}{2a' + (n -1)d' } . . . . . (i) \\[/tex]
Now also we know that the nth term of an AP is given by ,
[tex]\longrightarrow\sf\small \pink{ T_n = a + (n-1)d}\\[/tex]
Therefore,
[tex]\longrightarrow\sf\small \dfrac{T_{m_1}}{T_{m_2}}= \dfrac{ a + (n-1)d }{a'+(n-1)d'}. . . . . (ii)\\[/tex]
[tex]\longrightarrow\sf\small \dfrac{T_1}{T_2}=\dfrac{2a + (2n-2)d}{2a'+(2n-2)d'} . . . . . (iii)\\[/tex]
From equation (i) and (iii) ,
[tex]\longrightarrow\sf\small n-1 = 2m-2\\[/tex]
[tex]\longrightarrow\sf\small n = 2m -2+1 \\[/tex]
[tex]\longrightarrow\sf\small n = 2m -1 \\[/tex]
Substitute this value in equation (i) ,
[tex]\longrightarrow \sf\small \dfrac{2a+ (2m-1-1)d}{2a' +(2m-1-1)d'}=\dfrac{7(2m-1)+1}{4(2m-1) +27}\\[/tex]
Simplify,
[tex]\longrightarrow\sf\small \dfrac{ 2a + (2m-2)d}{2a' +(2m-2)d'}=\dfrac{14m-7+1}{8m-4+27}\\[/tex]
[tex]\longrightarrow\sf\small \dfrac{2[a + (m-1)d]}{2[a' + (m-1)d']}=\dfrac{ 14m-6}{8m+23}\\[/tex]

Which of the following proves triangles are congruent
Answer:
SAA
Step-by-step explanation:
This is because we see the triangles share two equal congruent angles and the one side where they touch each other. We don't know anything about the other sides so it cannot be ASA.
The two right-angled triangles are congruent by RHS so the correct option is neither.
What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
From the given figure two triangles share a common side which is their height.
The two triangles have the same measure of angles opposite to their base,
Therefore the bases of the triangles are also congruent.
Now, we know if two right-angled triangles have the same height and base
their hypotenuse must also be the same.
Now, the hypotenuse and one of the legs of the triangle is congruent to another right-angled triangle they are congruent by RHS or right-angled hypotenuse.

Jon = 1020
Bon = 2380
Please help, thanks.
Answer:
2. b) New amount = £6200
Same ratio → Jon : Bon = 3 : 7
6200 ÷ (3 + 7) = 620
⇒ 620 × 3 : 620 × 7
⇒ 1860 : 4340
Jon = £1860
Bon = £4340
3.
Tom : Thom : Thomas
= 2 : 3 : 5
= 2x: 3x : 5x
Given Tom received £2400:
⇒ 2x = 2400
⇒ x = 1200
2x: 3x : 5x
⇒ (2 × 1200) : (3 × 1200) : (5 × 1200)
⇒ 2400 : 3600 : 6000
Tom = £2400
Thom = £3600
Thomas = £6000
4.

Therefore, there are 40 dogs
Ram is 1 m 10 cm tall and Shyam is shorter by 20 cm. Find the height of Shyam
Shyam is 0.9 m
Step-by-step explanation:
10 cm = 10/100 m = 0.1 m
Now,
Ram = 1m + 0.1 m = 1.1 m
Now,
shyam = 1.1 m - 20 cm
= 1.1 m - 20/100 m
= 1.1 m - 0.2 m
= 0.9 m

The goal of this is to get 24 by multiplying the p value with q. q can be any number, as long as it gets to 24 in this scenario.
So your first p value is 4, so you can take 24, and divide it by 4 to get your answer.
24/4=6 then you can check it by multiplying 6*4=24. That means 6 is your first q value.
This will work for the rest of them in that table, except for the 0, because no matter what you multiply that by you cannont get 24. Try it out for yourself, goodluck!
Answer:
q- 24/4=6
24/2=12
24/0=0
24/-2= -12
24/-4= -6
Maria is training for a triathlon. Yesterday, she rode her bike for eight and two-thirds miles in two-thirds of an hour. If Maria continues to rides at the same rate, how far will she ride in one hour?
HELP
Answer:
She will ride 13 miles in one hour
Step-by-step explanation:
(8 2/3) / (2/3) = x / 1....8 2/3 miles to 2/3 hr = x miles to 1 hr
cross multiply
(2/3)(x) = (8 2/3)(1)
2/3x = 26/3
x = 26/3 * 3/2
x = 26/2...which equals 13....she will ride 13 miles in 1 hr

Think a moment about factoring a polynomial by finding the GCF.
Explain the role of the GCF in factoring a polynomial.
Where is the GCF placed after factoring the GCF?
How do you verify factoring is correct?
Answer/Step-by-step explanation:
Explain the role of the GCF in factoring a polynomial.
The role of the GCF in factoring a polynomial is the largest monomial that divides evenly into each term. GCF is a factor that is shared by all terms within a polynomial. For instance, if we have a polynomial of the form A*B + A*C, the GCF is A since both terms have A as a factor.
Where is the GCF placed after factoring the GCF?
After factoring out the GCF, it's placed outside the parentheses, in front of the rest of the polynomial. Like the sample we previous use A*B+A*C = A(B+C).
How do you verify factoring is correct?
To Verify factoring is correct distributing the GCF to the polynomial within the parentheses.
