Answer:
Day 13
Step-by-step explanation:
The question can be represented with a geometric sequence
Where,
a = 5
Common ratio , r = 2
v(t) = a * r^(t - 1)
v(t) = 5 * 2^(t-1)
20,000 = 5 * 2^(t-1)
Divide both sides by 5
20,000 / 5 = 5 * 2^(t-1) / 5
4,000 = 2^(t-1)
2^12 = 2^(t-1)
12 = t - 1
12 + 1 = t
t = 13 days
What would be the day when more than 20,000 people will see the video
Check:
v(t) = 5 * 2^(t-1)
= 5 * 2^(13-1)
= 5 * 2^12
= 5 * 4,096
= 20,480
Therefore,
The day when more than 20,000 people will see the video is day 13

a = [tex]6\sqrt{5}[/tex] is the right angled triangle's third side when the right angle triangle's opposite sides are 18 and 12, respectively.
what is triangle ?A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric forms. The name given to a triangle with the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.
given
by pythagoras theorem
c2 = a2 + b2
18*18 = a2 + 12*12

Here is a piece of cake each piece of cake has the same number of candles how old is rongopai
Rongopai's age is equal to the total number of candles on the cake, thus I need to determine what that is.
How to estimate Rongopai's age?What I need to figure out because I am aware that Rongopai's age is equal to the total number of candles on the cake.
The number of pieces the cake was sliced into must first be determined. A quarter has a specific appearance to me. This is how it would seem (the teacher traces a quarter shape on the circle). There must have been more than four pieces since this one seems a little smaller.
Each cut's location may be identified using my finger. Given that all the pieces must be the same size, I'm predicting the locations of each line using the first piece as a reference.
Here would be the approximate location of the first line, followed by here and here (the teacher draws a line with her finger) (tracing two more lines). the third line. In my mind, the lines and parts are somewhat "visible." Four "invisible" pieces plus the one drawn in are present when I count backward.
The complete question is:
A teacher wants a student to see how visualising the size of a share (in this case, a piece of cake) can be used to work out how many shares are needed to make a whole:
“Here is a piece of Rongopai’s birthday cake. Each piece of cake has the same number of candles. How old is Rongopai?”

What means one fifth of a circle?One fifth of a circle means if a circle can be divided into five equal parts, then one fifth is one of them.
How old is Rongopai?
As per the figure given, there is shown a 1 fifth of a circular birthday cake.
As all the piece of cake is equal in size so the total number of cake piece is five.
the number of candles in each piece is four.
the total number of candles present in the whole cake is = 5 × 4
the total number of candles = 20
Therefore, Rongopai is 20 years old.

What are supplementary angles?
Supplementary angles are two angles that add up to 180 degrees. They are angles that when placed together will form a straight line. They are called "supplementary" because they "supplement" each other to form a straight angle.
When two angles are supplementary, their measures add up to 180 degrees. So, if ∠A and ∠B are supplementary, then:
m∠A + m∠B = 180
Given that m∠A = (7x - 11)° and m∠B = (x - 25)°, we can substitute these values into the equation:
(7x - 11)° + (x - 25)° = 180
Simplifying this equation by combining like terms:
8x - 36 = 180
Adding 36 to both sides:
8x = 216
Dividing both sides by 8:
x = 27
Hence, the measure of ∠B is (x - 25)° = (27 - 25)° = 2°.

A gym offers classes for students to attend. If both the range and median number of students attending each class was 13 students, which of the following box-and-whisker plots could represent the number of students attending the classes?
Answer: C (The Last One)
Step-by-step explanation:
The answers correct because, If the range and median is 13 that means that the highest and lowest point equal 13 and the middle/the line in the graphs should be on 13. A doesn't have the line/median on 13 so it is not that answer. But B and C have the line/median on the line so we just have to check the range. The range of B is: 9, The range of C is: 13. So based off that we know that the answer is C.

The Fudd family is attending a family reunion. They plan to rent a
car from the ABC Car Rental Company. Let m represent the number
of miles the family will drive. Let c represent the cost for renting a
car. Complete problems
The complete problem equation will be c = k*m + b
The cost equation for renting a car from the ABC Car Rental Company in terms of the number of miles driven, m, and the cost, c, would likely take the form of:
c = k*m + b where k is the rate of cost per mile and b is the fixed cost for renting the car independent of the miles driven.
It is important to note that this is a general equation and the specific cost equation of the ABC Car Rental Company is not provided. Also, this equation assumes that the cost of renting a car is linear to the miles driven, which may not be the case in practice. Other factors such as the type of car and duration of the rental period could also be included in the cost equation.
Therefore, the problem equation will be c = k*m + b

Two dice are rolled at the same time. The first die shows a 2. Given that is a random variable that represents the sum of the results shown by the two dice, what are the possible values of X?
Answer:
3 ≤ X ≤ 8
Step-by-step explanation:
A die has 6 faces numbered from 1 to 6.
If two dice are rolled at the same time and the first die already shows a 2. Then the second die will show any number between 1 and 6 inclusive.
X which is the sum of the results shown by the dice will always be greater than or equal to 3 but less than or equal to 8. This is because the first die already shows a 2 and the second die will always be a number between 1 and 6 inclusive. i.e
X = result from die 1 + result from die 2
X = 2 + [1, 6]
X = [3, 8]
In other words, the minimum value of X is 3 and the maximum value of X is 8.

a. The markup rate is the constant of proportionality in the equation y= kx. Write an equation that can be used to find the amount of markup on the cost x of a phone
b. Use the equation to calculate the markup amount. What is the retail price of a phone?
c. Next week the store is going to reduce the price to $31. 50. Calculate what percent the sale price is of the retail price.
d. Based on your answer to part C, what is an equation in the form y = kx that relates the sale price to the retail price x?
Answer:
a. y = 2.5x
b. markup: $30; retail price: $42
c. 75%
d. y = 0.75x
Step-by-step explanation:
You want equations relating markup, retail price, and sale price on a phone that costs $12, is marked up 250%, then put on sale for $31.50.
a. Markup equationThe problem statement tells you the markup is 250% of the cost. You could write the equation as ...
y = (250%)x
Or you can simplify it to a decimal number:
y = 2.5x
b. Markup amountThe markup amount is ...
y = 2.5(12) = 30
The markup amount is $30.
That is added to the cost to get the retail price:
retail = $12 +30 = $42
The retail price of the phone is $42.
c. Sale priceThe sale price as a percent of the retail price is ...
percent = (sale price)/(retail price) × 100%
percent = 31.50/42 × 100% = 75%
The sale price is 75% of the retail price.
d. Sale price equationAs in part (a), we could write this as ...
y = (75%)x
or, in decimal, as ...
y = 0.75x
