Answer:
Inductive reasoning is the opposite of deductive reasoning. Inductive reasoning makes broad generalizations from specific observations. Basically, there is data, then conclusions are drawn from the data. ... Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false.

1 unit = 10 ft
How long is the cable? Round your answer
to the nearest whole foot.
This value is approximate.
==========================================================
Explanation:
The cable is connected by these key points
A = (0,3)B = (6,5)C = (12,4)D = (18,2)Let's use the distance formula to find the length of segment AB.
[tex]A = (x_1,y_1) = (0,3)\\\\B = (x_2,y_2) = (6,5)\\\\d = \text{Distance from A to B} = \text{length of segment AB}\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-6)^2 + (3-5)^2}\\\\d = \sqrt{(-6)^2 + (-2)^2}\\\\d = \sqrt{36 + 4}\\\\d = \sqrt{40}\\\\d \approx 6.325\\\\[/tex]
Segment AB is roughly 6.325 units long. You could use the pythagorean theorem as an alternative route instead of the distance formula.
If you repeated this process for the other segment lengths, then you should get these other approximate lengths.
BC = 6.083CD = 6.325Add up those three results:
AB+BC+CD = 6.325+6.083+6.325 = 18.733
The entire cable is roughly 18.733 units long.
Since 1 unit = 10 feet, we'll multiply that result by 10.
18.733*10 = 187.33 feet
This rounds to 187 feet which is the approximate length of the cable.
The length of the cable will be 187.2 feet long.
What is the distance between two points?Let one point be (x, y) and another point be (h, k). Then the distance between the points will be
D² = (x - h)² + (y - k)²
From the diagram, the length between (0, 3) and (6, 5), (6, 5) and (12, 4), and (12, 4) and (18, 2) will be the length of the cable (L).
[tex]\rm L = \sqrt{(6 - 0)^2 + (5-3)^2} + \sqrt{(12 - 6)^2 + (4 - 5)^2} + \sqrt{(18 - 12)^2 + (2 - 4)^2}\\[/tex]
Simplify the equation, then we have
L = √40 + √37 + √40
L = 6.32 + 6.08 + 6.32
L = 18.72 units
L = 18.72 x 10
L = 187.2 ft
The length of the cable will be 187.2 feet long.

Step-by-step explanation:
2 times x is 2x
The sum of 2 times x and 6 is 2x + 6
And we do 4 times that, making sure to put 2x + 6 in parentheses; we're multiplying 4 times the entire sum.

Find the length of the arc
Answer:
C
Step-by-step explanation:
There are two arcs a major and a minor arc. You should never have to rely on a diagram to get the right answer.
The circumference is 2 * pi * r
r = 6 km
C = 2* pi * 6
C = 12 pi
The arc size is
arc size = 135 / 360 * 12pi
arc size = 3/8 * 12 pi
arc size = 4 1/2 pi = 9 pi /2 km
Solve for the value of k
Answer:
4k-7 + 3k+ 6 = 90
7k -1 = 90
7k = 91
k=13
Step-by-step explanation:
Notice that if we add the 3 angles in the image, the outcome should be an angle of 180° (the one of the line alone)
With this, we will found that the answer is k = 13
Let's do the math, for the initial information we can write:
(4k - 7)° + 90° + (3k + 6°) = 180°
Where the 90° comes from the right angle, the one written with a little square.
Now we can solve this for k
(4k - 7)° + 90° + (3k + 6°) = 180°
(4k + 3k)° + (-7° + 90° + 6°) = 180°
7°k + 89° = 180°
7°k = 180° - 89° = 91°
k = 91°/7° = 13
So we found that the value of k is 13.

EMERGENCY A speeding ticket costs $80 plus $10 for each mile per hour over the speed limit the violator was traveling. How much would someone going 12 miles per hour faster than the speed limit have to pay for their ticket?
Answer:
$200
Step-by-step explanation:
Fine calculated per mile = $10
Fine calculated for 'm' mile = 10 * m = 10m
Cost paid by violator = 80 + 10m
m = 12 miles
Cost paid by the violator = 80 + 10*12
= 80 + 120
= $ 200

Answer:
B) 74
Step-by-step explanation:
This is an icoseles triangle because of the 2 lines in each side. This makes <Y equal to <Z
Given:
<Y = <Z
All triangle angles add up to 180 so:
<W + <Y + <Z = 180
<W + 53 + 53 = 180
<W + 106 = 180
<W = 180 - 106

Xian and his cousin Kal both collect stamps. Xian has 52 stamps, and Kal has 68 stamps. The boys recently

send him 16 new stamps per month. After how many months will Xlan and Kal have the same number of
stamps? How many stamps will each have?
Answer:
In 4 months, they will both have 132 stamps.
Step-by-step explanation:
Let x = # of months
52 + 20x = 68 + 16x
4x = 16
x = 4
Plug x value into both expressions and see if it checks out
52 + 20(4) = 68 + 16(4)
52 + 80 = 68 + 64
132 = 132

Because the subtraction sign is after the negative, it applies to the term in front of it, in this case because there is a parenthesis, it would multiply into that and your equation from there would be 1-4-3x<-3. Then combine like terms from there.

Answer:
quadrilateral has 4 sides
so 104°+40°+110°+x=360°
254°+x=360°
collect like terms
x=360-254
x= 106
;- x=106
which is (c)
Answer:
x = 106°
Step-by-step explanation:
Using the angle marked 110° as my starting point,
One can use angles on a straight line sum up to 180° to find the angle that adds up to 110° which makes it 180,
thus 70°.
moving on,
tackling with the angle marked 40°, Using the fact that angles on a straight line sum up to 180°, the angle obtained will be 140° (40° + a = 180, a = 180° -40°, a = 140°)
Using the angle marked 104°, Just like the previous one Using the principle that angles on a straight line sums up to 180°, then the unknown angle will be 76°.
Finding all the other interior angles angles in the quadrilateral except the angle in line with the x,
the next step to take is to add up all the angles Using any variable and equate it to 360°
why? angles in this type of quadrilateral equals 360,
That is,
140° + 76° + 70° + y = 360
286 + y= 360
y = 360 - 286
y = 74
The final step now is to use the principle, ( angles on a straight line sums up to 180)
74° + x = 180
x = 180 - 74
x = 106°
