The location of T is 3 units from the midpoint X or 6 units from the endpoint B
Midpoint of a Line
In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints.
Since one of the endpoints is BX and the endpoint is XT and the midpoint is X.
The distance between B and X is 3 units.
Since X is the midpoint, the distance between X and T is equal to 3 units.
Therefore, the distance between B and T is 6 units and the location of T is 3 units from X or 6 units from T.

A merchant bought several pieces of silk for $70. He sold all but two of them at a profit of $4 per piece. His total profit was $18. How many pieces did he originally purchase?
Let n be the number of pieces. He sold n - 2 pieces
Let p be the original price. His selling price = p + 4
Then n · p = 70.00
And (n - 2) · (p + 4) = 70.00+18.00 ---> np + 4n - 2p - 8 = 88.00
---> np + 4n - 2p = 96.00
---> 70.00 + 4n - 2p = 96.00
4n - 2p = 26.00
2n - p = 13.00
Trying some possibilities (7 & 1), (8 & 3), (9 & 5), and (10 & 7), finally gets us to the answer: n = 10 and p = 7.00.

Answers
450 m² of metal are needed to cover the sides of the pyramid.
The correct answer is an option (A)
In this question, a monument is made in the form of a right pyramid with a regular hexagon as a base. each base side is 5 meters and the slant height is 30 meters.
If only the sides (and not the base) of the monument is to be covered by metal, we need to find the amount of metal needed to cover the sides of the pyramid.
Since the base of the pyramid is hexagon, there are 6 triangular sides of the pyramid.
We need to find the area of 6 triangular surfaces.
The base of the triangle b = 5 meters and the height of the triangle is the slant height of the pyramid.
h = 30 meters
So, area of the one triangular surface would be,
A1 = 1/2 × b × h
A1 = 1/2 × 5 × 30
A1 = 5 × 15
A1 = 75 square meters
And the area of the 6 triangular surfaces would be,
A = 6 × A1
A = 6 × 75
A = 450 square meters
Therefore, 450 m² of metal are needed to cover the sides of the pyramid.
The correct answer is an option (A)

A plant biologist studies the height of sunflowers. He measures a large sample of sunflowers and creates a probability distribution. The distribution is normal in shape with mean 112 cm and standard deviation 16 cm.
What is the probability (approximately) that a sunflower will be less than 136 cm tall?
Enter a number in decimal form, e.g. 0.68, not 68 or 68%.
Answers
The probability that sunflower will be less than 136 cm tall is 0.9332.
How to calculate the probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
From the information, the biologist measures a large sample of sunflowers and creates a probability distribution and the distribution is normal in shape with a mean 112 cm and a standard deviation 16 cm.
It should be noted that the following can be deduced:
Mean = 112
Standard deviation = 16
Sunflower should be less than 136. This will be x < 136.
Therefore, the probability will be;
P(X < 136)
= P(Z < [(number - mean) / standard deviation)]
= P(Z < [136 - 112)/16]
= P(Z < 1.50)
= 0.9332
It should be noted that the probability is gotten by looking at the value of x in the z table.

-1.1<< 2 - sqrt 10 < -1.2 will be the answer but doesn't look like its right. Appreciate your help for this. thanks
Answers
Think of -1.1 as -11
Think of -1.2 as -12
I moved the decimal points to the right for each value
Then on a vertical number line, notice how -12 is below -11, so -12 < -11
If we divide both sides by 10, then we go from -12 < -11 to -1.2 < -1.1
In short, the final expression you have -1.1 < middleStuff < -1.2 is in the wrong order.
It should be -1.2 < 2 - sqrt(10) < -1.1
I swapped the places of -1.1 and -1.2
If you were to use a calculator, then 2-sqrt(10) = -1.162 approximately which fits the description of being between -1.2 and -1.1; this helps confirm we have the correct upper lower and upper bounds.
------------------------------------
Here's another way to look at it
3.1 < sqrt(10) < 3.2
-1*3.1 > -1*sqrt(10) > -1*3.2 ............ see note1 below
-3.1 > -sqrt(10) > -3.2
-3.1+2 > -sqrt(10)+2 > -3.2+2 ....... see note2
2-3.1 > 2-sqrt(10) > 2-3.2
-1.1 > 2 - sqrt(10) > -1.2
-1.2 < 2 - sqrt(10) < -1.1 ........... see note3
Footnotes
note1: For this step I multiplied all three sides by -1. Multiplying by a negative will flip the inequality signsnote2: I added 2 to all three sides. This does not flip any of the inequality signs.note3: We go from the form a > b > c to c < b < a. The outer sides 'a' and 'c' swap places while b in the middle stays where it is.

Range and Domain. The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
What Separates a Function's Domain from its Range?
A function's domain and range are its constituent parts. In contrast to a function's range, which is the set of all potential outputs, a function's domain is the set of all possible inputs.

Shantel told her hired hand Warren to gather eggs from the henhouse. Warren collected 30 eggs and brought them to Shantel. Shantel inspected
them and complained that 40% of them were broken. How many of them were still good eggs?
eggs were still good.
Answers
Answer:
18 eggs are still good.
Step-by-step explanation:
If 40% was broken then 60% are still good.
30(.6) = 18
Answer: 18 eggs were not broken and considered good.
Step-by-step explanation: 30 x 40% is the amount of eggs that were broken.
30 x 60% would be the amount of eggs that were still good.
This is becuase the total percentage must add up to be 100% between good eggs and broken eggs.
30 x .60 = 18 So 18 eggs were good
30 x .40 = 12, so that was the number of eggs that were broken
You could have done this problem two ways. Either calculate the broken eggs and subtract from the total. 30-12 = 18, or you could have just calculated the correct amount from figuring the percentage of eggs that were good from the beginning.
1) Is it possible to end up with two different prime factorizations for a number, or will you always end up with the same list of prime factors?
2) What was true about all of the numbers in the final lists of factors? Why?
3) Can two different numbers have the same prime factorization? Why or why not?
4) Explain how writing a number as a product of prime numbers is a way of representing that number.
How does knowing that the prime factorization of 40 is 2 × 2 × 2 × 5 help you know every possible factor of 40?
5) How is what you did in the Action Task related to the colour code in the Minds On Activity?
Answers
1) A prime factorization of a particular number will always give the same prime factors.
2) All the factors in the list when multiplied will give the original number.
3) No, two different numbers cannot have the same prime factorization.
4) The prime factors of 40 are 2 and 5.
1) We anticipate finding factors in prime factorization that can add to themselves to get the original number. The original number can be obtained by multiplying the remaining components together as long as the first factor can divide the quantity without leaving a remnant.
Prime factorization of the number, 15 goes thus;
15/3=5
5/5=1
3*5=15
So, all the factors multiply to give the original number.
2) Numbers that split an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal halves.
3) The collection of prime numbers that can be multiplied together to produce a given number is known as the prime factorization of that number. Because the same set of numbers must provide the same result when multiplied together, two separate numbers cannot have the same prime factorization.
4) Any number can be represented as a sum of prime numbers using prime factorization. A number with exactly two elements, 1 and the number itself, is said to be a prime number. As an illustration, the prime factorization of 18 is 2 3 3. Here, the two main elements or prime factors of 18 are 2 and 3.
The prime factorization of 40 is :
40 = 2 × 2 × 2 × 5
