(ANSWER QUICK PLEASE)1. Kasey noticed that the distribution of candy bars in the variety bags of candy bars is always the same. There are three times as many Twix Bars as Milky Ways. There are 5 fewer snickers than there are Twix.
Using proportions, the amounts are given as follows:
Small: 24 Twix, 8 Milky Ways, 19 Snickers.Medium: 30 Twix, 10 Milky Ways, 25 Snickers.Large: 42 Twix, 14 Milky Ways, 37 Snickers.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
We have that the amount of Twix is triple the amount of Milky ways, hence:
In the small bag, there are 8 x 3 = 24 Twix.In the medium bag, there are 30/3 = 10 Milky Ways.There are 5 fewer Snickers then Twix, hence:
In the small bag, there are 24 - 5 = 19 Snickers.In the medium bag, there are 30 - 5 = 25 Snickers.In the large bag, there are 37 + 5 = 42 Twix and 42/3 = 14 Milky Ways.Hence the amounts are given as follows:
Small: 24 Twix, 8 Milky Ways, 19 Snickers.Medium: 30 Twix, 10 Milky Ways, 25 Snickers.Large: 42 Twix, 14 Milky Ways, 37 Snickers.More can be learned about proportions at https://brainly.com/question/24372153

Find the range of the following piecewise function.
[0,11)
(-4,6]
(0,11]
[-4,6)
Given:
The piecewise function is
[tex]f(x)=\begin{cases}x+4 & \text{ if } -4\leq x<3 \\ 2x-1 & \text{ if } 3\leq x<6 \end{cases}[/tex]
To find:
The range of given piecewise function.
Solution:
Range is the set of output values.
Both functions [tex]f(x)=x+4[/tex] and [tex]f(x)=2x-1[/tex] as linear functions.
Starting value of [tex]f(x)=x+4[/tex] is at x=-4 and end value is at x=3.
Starting value: [tex]f(-4)=-4+4=0[/tex]
End value: [tex]f(3)=3+4=7[/tex]
Starting value of [tex]f(x)=2x-1[/tex] is at x=3 and end value is at x=6.
Starting value: [tex]f(3)=2(3)-1=5[/tex]
End value: [tex]f(6)=2(6)-1=11[/tex]
Least range value is 0 at x=-4 and 0 is included in the range because -4 is included in the domain.
Largest range value is 11 at x=6 and 11 is not included in the range because 6 is not included in the domain.
So, the range of the given piecewise function is [0,11).
Therefore, the correct option is A.

2 Answers:
Choice B) irrational
Choice F) Natural
=====================================================
Reason:
Let's go through the answer choices.
A) The value 0 is a real number. A real number is any thing you can think of such as 2/3 or [tex]\sqrt{93}[/tex] or 10.657 or 22, assuming your teacher hasn't covered imaginary or complex numbers. This rules out choice A.B) This is one of the answers. See choice C for further explanationC) The value 0 is rational since 0 = 0/1 is a fraction of two integers, where the denominator is nonzero. Since 0 is rational, it means it cannot be irrational. The term "irrational" means "not rational". Therefore, we can conclude that 0 is not in the set of irrational numbers. This is why choice B is one of the answers, and why we can rule out choice C.D) The set of integers is {...., -3, -2, -1, 0, 1, 2, 3, ...} which consists of positive and negative whole numbers. We also have 0 in this set. So choice D is ruled out. E) The set of whole numbers is {0, 1, 2, 3, 4, ...} which has 0 in it. We can rule out choice E.F) The set of natural numbers is very similar to the whole numbers, but one key difference: zero is missing. The natural numbers is {1, 2, 3, 4, ...} which shows that choice F is the other answerIf the binomial (x−7) is a factor of the polynomial function f(x), which statement must be true?
If the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0
How to determine the true statement?The given parameters are
The binomial (x−7) is a factor of the polynomial function f(x)
The above means that
When the function f(x) is divided by x - 7, it has no remainder
So, we have
x - 7
Set to 0
x - 7 = 0
Add 7 to both sides
x = 7
Substitute x = 7 in f(x) = 0
f(7) = 0
Hence, if the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0

The measure of C'T' is √17 units after the rotation .
Rotation of a graph is a transformation in which the figure is rotated around a fixed point.
The rotation can be clockwise or anti-clockwise.A complete rotation of 360 degrees puts the graph back into its original position.Rotation does not change the side length of the figure that is rotated.When a polygon is rotated about a fixed point then the transformed figure is congruent to the original figure.The given triangle is CAT and it has the coordinates as C(0,0) , A(-2,1) and T(-1,4).
So when the figure is rotated about a fixed point the side lengths will remain same as the original figure.

I could have given up, but I thought about my grandmother. She always told me that "people who believe that science is the answer to everything are missing out on everything else." With her words in mind, I searched some more. There were many facts that hinted that dragons may not be fictional. I noticed that cultures across the world all described dragons in similar ways. This was odd because they had no way to communicate with each other. I found dragons mentioned in more than just stories. They appeared in old legal papers, in the travel logs of Marco Polo, and in the Bible. I saw that the Chinese calendar uses a different animal each year. Dragons are included along with eleven real animals. I began to believe it was a real possibility that all of these people were talking about a creature that actually existed.
The text discusses the Chinese calendar by writing, "Dragons are included along with eleven real animals."
What does that imply? (5 points)
Dragons are the only fake animal on the Chinese calendar.
Dragons are not the only fake animal on the Chinese calendar.
Dragons are real because all the other animals on the calendar are fake.

Smallest possible value of the least common multiple is 6
a =12 and b=54
In mathematics, the greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted as GCD(x,y)=[tex]\frac{x*y}{LCM(x,y)}[/tex]

A seal went 25 feet below sea level to catch a fish. A sea lion dove 10 feet less than three times as deep as the seal to catch a larger fish. What is the sea lion's position in relation to sea level?
Answer:
65 feet below sea level.
Step-by-step explanation:
With the information provided, we can create the following equation for the position of the sea lion (p)
p = 3x - 10
In this equation, x would be the final position of the seal when it caught the fish. Since we are told that the seal's position is 25 feet below sea level then we can plug in this value as x and solve for p...
p = (3 * 25) - 10
p = 75 - 10
p = 65
Finally, we can see that the sea lion's position is 65 feet below sea level.

Answer:
The domain of the function is:
[tex]\mathrm{Domain\:of\:}\:\sqrt{x+5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:[-5,\:\infty \:)\end{bmatrix}[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)\:=\sqrt{x+5}[/tex]
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
From the function, it is clear that for the values x<-5, the function becomes undefined.
For example, for x=-6
√x+5 = √-6+5 = √-1 which is undefined
and for x=-5
√x+5 = √5+5 = √0 which is defined
Thus, the domain of the function is:
[tex]\mathrm{Domain\:of\:}\:\sqrt{x+5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:[-5,\:\infty \:)\end{bmatrix}[/tex]

A contractor bought 8.2 ft^2 of sheet metal. He had used 4.9ft^2 so far and has $ 59.40 worth of sheet metal remaining. The equation 8.2x-4.9x=59.4 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer: Each square foot of metal costs $14.97
Step-by-step explanation:
He initially had 8.2 ft^2 of metal.
He used 4.9ft^2 of metal, then he now has:
8.2 ft^2 - 4.9 ft^2 = 3.3 ft^2
And this 3.3 ft^2 is whort $49.40
Then if X is the cost per square foot, we have the equation:
3.3ft^2*X = $49.40
We can solve it for X as:
X = ($49.40/3.3ft^2) = $14.97 ft^-2
This means that each square foot costs $14.97
Given f(x)=5x+4, solve for x when f (x) = -6
