Answer:
50:1
Step-by-step explanation:
To simplify the ratio 50:1, we find the greatest common divisor of 50 and 1, and then we divide 50 and 1 by the greatest common divisor.
The greatest common divisor that you can use to simplify 50:1 is 1. Which means the answer to ratio 50:1 simplified is:
50:1

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).

Work out the mean for the data set
below:
2.3, 0.3, 7,6.1, 9.7
Give your answer as a decimal.
Answer:
Mean = 5.08
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
[tex] \frac{2.3 + 0.3 + 7 + 6.1 + 9.7}{5} [/tex]
[tex] = \frac{25.4}{5} [/tex]
= 5.08

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as
Daniel.
Let k be Kevin's age and let d be Daniel's age.
Which system of equations renresents this situation?
Answer:
k - 2 = 4d - 8
d + 1 = 4d - 8
Step-by-step explanation:
Daniel's age = d
Kevin's age = k
Given that, k = d + 3 -------------- (1)
Two years ago, the age of Daniel = d - 2
Two years ago, the age of Kevin = k - 2
Since, two years ago, Kevin was 4 times as old as
Daniel, k - 2 = 4(d - 2)
Opening the bracket,
k - 2 = 4d - 8
Since the value of k is d + 3 (see (1))
d + 3 - 2 = 4d - 8
d + 1 = 4d - 8
(I am just giving the answer cause I LOVE Linear Equation )
1 + 8 = 4d - d
9 = 3d
9/3 = d
3 = d
Therefore, Daniel's present age is 3 and Kevin's present age = 6

What is the difference in the volume of a cylinder having a radius of 4 and a height of 8, and the volume of a rectangular prism having dimensions of length = 10, width = 7 and height = 6? Use 3.14.
Round to the nearest hundredth.
===========================================
Work Shown:
The cylinder has volume of...
V = pi*r^2*h
V = 3.14*4^2*8
V = 401.92
----------------
The rectangular prism has a volume of...
V = L*W*H
V = 10*7*6
V = 420
----------------
Subtract the two results:
420-401.92 = 18.08
The cylinder has roughly 18.08 more cubic units of volume compared to the rectangular prism.
Answer:
volume of cylinder: V=Sđ*h=R^2*3.14*8
volume of rectangular prism: V=Sđ*h=10*7*6

Consider the line y=8x - 3
Find the equation of the line that is parallel to this line and passes through the point (3, -2)
Find the equation of the line that is perpendicular to this line and passes through the point (3, -2)
Answer:
y=8x-26
y=-1/8x-13/8
Step-by-step explanation:
Y=kx+b
When the two lines are parallel,
k1=k2
k2=8 And passes through the point (3, -2)
So y+2=8(x-3)
Get the answer y=8x-26
When the two lines are perpendicular,
k1*k2=-1
K2=-1/8 And passes through the point (3,-2)
So y+2=-1/8(x-3)
Get the answer y=-1/8x-13/8

(NO LINK PLS <3)
Answer:
13
Step-by-step explanation:
To find the range substitute the value of x from the domain into the equation.
x = - 2 : y = -5(- 2) + 3 = 10 + 3 = 13
x = 0 : y = - 5(0) + 3 = 0 + 3 = 3
x = 1 : y = - 5(1) + 3 = - 5 + 3 = - 2
x = 3 : y = - 5(3) + 3 = - 15 + 3 = - 12
range is { - 12, - 2, 3, 13 }
with greatest value in the range being 13

have completed 816 miles which is 46% of the trail. Can you find about how many miles for the total trip?
Answer:
1773.91 miles
Step-by-step explanation:
Given data
Completed miles= 816 miles
Percentage completion= 46%
Let the total distance be x
Hence
46% of x= 816
let us find x
46/100*x= 816
0.46x=816
x= 816/0.46
x= 1773.91
Therefore the total distance is 1773.91 miles
What value of x makes the equation true? 16 + (18+ 10) = (x +18) +10 x=

18+10+x=28+x
44-28=x
x=16
A fair coin is tossed n times. For which value of n can the experimental probability of tossing tails equal the theoretical probability?
Answer:
The value of the coin tosses per time in the air
Step-by-step explanation:
The value of n for which the experimental probability of tossing tails can equal the theoretical probability is any even number.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The theoretical probability of tossing tails in a fair coin is 0.5 or 1/2.
The experimental probability of tossing tails in n trials is the number of times tails appear divided by n.
So, we want to find a value of n such that:
number of times tails appear / n = 0.5
Solving for n:
number of times tails appear = 0.5n
Since the number of times tails appear must be a whole number, n must be even.
This is because if n is odd, then it is not possible to have exactly half the trials result in tails.
For example,
If n=3, the possible numbers of tails that can appear are 0, 1, 2, or 3. Half of 3 is 1.5, which is not a whole number, so it is impossible to have exactly half the trials result in tails.
On the other hand,
If n=4, the possible numbers of tails that can appear are 0, 1, 2, 3, or 4.
Half of 4 is 2, which is a whole number, so it is possible to have exactly half the trials result in tails.
Therefore,
The value of n for which the experimental probability of tossing tails can equal the theoretical probability is any even number.

Would you rather be reborn into the past or future? Why?
Would you rather go into the past and meet your ancestors or go into the future and meet your great-great grandchildren? Why?
Would you rather have a rewind button or a pause button on your life? Why?
(I'm aware that this isn't a mathematical question, this is simply just for fun:)
Answer:
Future just cause I don't really have much interest about the past, moving forward as always. I'd like to see how things advance over time :")

Patterns are made using straight lines and arcs.
Pattern A (one row)
Pattern B (two rows)
More rows are added to Pattern B so that
number of straight lines : number of arcs = 7:6
How many rows are added?
5 rows are to be added in the pattern if the ratio will be 7:6 between number of straight lines.
What is a pattern?
A pattern is a sequence. It can be an AP, GP also.
How to determine the number of rows to be added?
present ratio between number of straight lines and number of arcs
=8:9
When we add 1 row it will increase 4 straight lines and 3 arcs. So when 5 rows are added it will increase 20 straight lines and 15 arcs.
Then total number of straight lines will be 28 and the total number of arcs will be 24 and the ratio will be 28:24 which after dividing by 4 becomes 7:6.
Hence 5 rows are to be added in the pattern B to get the ratio 7:6.
