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

Hence, the prime factors of 40 are 4 and 5.

Answer: 16 miles

Step-by-step explanation:.

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.

therefore

If a skier travels 4700 feet up a ski lift whose angle of inclination is 30°​, how high above his starting level is the​ skier is 2350 feet.

Given data:

Distance = 4700 feet

Angle of inclination = 30°​

Now let determine the height by  formulating an equation which will help us to find the height

4700 × sin 30°

Where:

Sin 30° = 0.5 or 1/2

Hence,

Height :

Height = 4700 feet × 0.5

Height = 2350 feet

So,

Height = 2350 feet above the starting level

Therefore we can conclude that the skier is 2350 feet above the starting level.

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

The probability that sunflower will be less than 136 cm tall is 0.9332.

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.

Step-by-step explanation:

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.

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.

All real numbers fall under the expression's domain, with the exception of cases where it is undefined. No real number exists in this situation, rendering the statement undefinable.

The number of gallons in 6 containers is 4

The statement is given as

A container has a capacity of 2/3 gallons

This means that

1 container = 2/3 gallons

Multiply both sides of the equation by 3/2

So, we have

3/2 * 1 container = 2/3 gallons * 3/2

Evaluate the products

So, we have

3/2 containers = 1 gallon

Multiply both sides by 4

So, we have

4 * 3/2 containers = 4 gallons

This gives

4 gallons = 6 containers

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.
