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 :")
I think a rewind is more useful in this case if I am able to correct my mistakes or have a moment back again, I'd like that.

Step-by-step explanation:
The two angles form a straight line which is 180 degrees
5+x +75 = 180
Combine like terms
x+80 = 180
Subtract 80 from each side
x +80-80=180-80
x = 100

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

(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

What is the explicit formula for this sequence?
-6, -2, 2, 6, 10,....
Answer:
4n-10
Step-by-step explanation:
First we will use n as any number.
the difference between each of the numbers is +4
This creates first part of the formula.
4n...
If you do 4n and replace n as one (For the first number of the sequence) then 4×1=4. You then have to find out how much you need to add or subtract to get -6 so the difference between 4 and -6 is -10.
This creates the second part of our formula.
4n - 10
You can check this by doing the same thing for the second number and replacing n with 2.
2×4=8
8 - 10= -2 which is the second number in the sequence which confirms this is correct.
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.

if 5k - 14= 26, then what is k?
Answer:
k = 8
Step-by-step explanation:
5k - 14 = 26
5k - 14 + 14 = 26 + 14
5k = 40

solve for j
PLEASE SHOW WORK IF YOU CAN
Answer:
j = 15
Step-by-step explanation:
The angles shown form a straight line
Angles on a straight line must add up to 180 degrees
Hence, 2j + 32 + 6j - 2 + 30 = 180
( note that we just created an equation that we can use to solve for j )
We now solve for j using the equation we created.
2j + 32 + 6j - 2 + 30 = 180
step 1 combine like terms
2j + 6j = 8j
32 - 2 + 30 = 60
we now have 180 = 8j + 60
step 2 subtract 60 from each side
60 - 60 cancels out
180 - 60 = 120
we now have 120 = 8j
step 3 divide each side by 8
120 / 8 = 15
8j / 8 = j
we're left with j = 15

SOMEONE PLS HELP ME FIND X
Answer:
step one you look at the question until you find the ex cuz it says 125 degrees and 125 degrees 2x
Answer:
x = 50
Step-by-step explanation:
The sum of all entire angles in this, esentially a pentagon, add up to 540
To find x, use the following
540 = 125 + 125 + 90 + 2x + 2x
540 - 125 - 125 -90 = 4x
200 = 4x
200 / 4 = x
50 = x
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.

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
