1. Is it possible for a composite number to have more than one prime factorization? Is it possible for a number to have no prime factors? Why?
2.Give and example of how prime factorization could be used in the real world

Answers

Composite number is defined as a number that can be divided by numbers aside from 1 and by itself.

Prime number are numbers that only has a factors of 1 and itself.

It is very possible for a composite number to have more than one prime factorization. But, it is not possible for a number to not have a prime factor. 

When you factorize a number, you break it down into its most basic factors and these basic factors are all prime numbers.

Prime factorization is basically breaking down numbers to its most basic factors. It can be used in everyday living especially when we deal with numerical transactions like money and values.

how is 2.25 written as a fraction

Answers

2.25 as a fraction is 2 1/4
'There is not much that can be done to figure out how to write 2.25 as a fraction, except to literally use what the decimal portion of your number, the .25, means. Since there are 2 digits in 25, the very last digit is the "100th" decimal place. So we can just say that .25 is the same as 25/100.' -Google

So 25/100 is your answer.

A culture of 1.08×10^15 bacteria is in petri dish A. A culture of 2.7×10^11 bacteria is in petri dish B.

How many times greater is the number of bacteria in petri dish A than petri dish B?

Enter your answer, in standard notation, in the box.

Answers

To find the number of times the bacteria in petri dish A than petri dish B, let us divide.

So, number of times = [tex]\frac{Number of times bacteria in petri dish A}{Number of times bacteria in petri dish B}[/tex]

[tex]= \frac{1.08(10^{15} )}{2.7(10^{11} )}[/tex]

= 0.4 × [tex]10^{4}[/tex]

= 4000

Hence, the number of bacteria in petri dish A is 4000 times the number of bacteria in petri dish B.

Change the order and the grouping of the addends so that you can use mental math to find the sum. Then find the sum. 43+39+43+11=

Answers

Final answer:

By applying the commutative property of addition and rearranging the numbers for easier mental calculation, the sum of 43 + 39 + 43 + 11 can be found to be 136.

Explanation:

The question asks to change the order and the grouping of the addends for easier mental calculation, and then to find the sum of 43 + 39 + 43 + 11. By understanding the commutative property of addition, which states that numbers can be added in any order without changing the sum, we can rearrange these numbers for easier addition.

To use mental math effectively, grouping numbers that make round numbers or those that are easier to add can simplify the process. Here, we can group 43 and 43, which are identical, and 39 and 11, which sum up to a round number.

Therefore, by rearranging:

43 + 43 = 86

39 + 11 = 50

Adding these sums together:

86 + 50 = 136

By changing the order and grouping of the addends, we find that the sum is 136.

An airplane can travel at a speed of 550 mph. Write and solve an equation to find the time it will take to fly from London to Montreal, a distance of approximately 3300 miles

Answers

Final answer:

The time it will take for an airplane to fly from London to Montreal at a speed of 550 mph covering a distance of 3300 miles is approximately 6 hours.

Explanation:

To find the time it will take for an airplane to fly from London to Montreal, we can use the equation for speed, which is:

Speed = Distance \u00f7 Time

Knowing that the plane can travel at a speed of 550 mph and the distance from London to Montreal is 3300 miles, we can rearrange the equation to solve for time:

Time = Distance \u00f7 Speed

Time = 3300 miles \u00f7 550 mph

After calculating, we find that:

Time = 6 hours

Therefore, it will take the airplane approximately 6 hours to fly from London to Montreal at a constant speed of 550 mph, ignoring any other factors such as wind or air traffic delays.

Final answer:

To find the time it will take, we can use the formula Time = Distance/Speed. In this case, it will take approximately 6 hours to fly from London to Montreal.

Explanation:

To find the time it will take to fly from London to Montreal, we can use the formula Time = Distance/Speed. In this case, the distance is approximately 3300 miles and the speed is 550 mph.

Plugging in the values into the formula, we get Time = 3300 miles / 550 mph = 6 hours. So, it will take approximately 6 hours to fly from London to Montreal.

Therefore, the time it will take to fly from London to Montreal is 6 hours.

Avery writes an equation that models the total price of visiting the museum as a function of the number of special exhibits they view.

Now, let the function be,

f(x)= 3x+5  = the total price of visiting the museum

So far, 37 miles of a new highway have been completed. This is one mile less than two thirds of the entire length. How long will the new highway be when complete?

Answers

37 = 2/3x - 1
37 + 1 = 2/3x
38 = 2/3x
38 / (2/3) = x
38 * 3/2 = x
114/2 = x
57 = x <=== when complete, the highway will be 57 miles
Final answer:

The total length of the new highway, when complete, will be 57 miles.

Explanation:

The question states that 37 miles of a new highway have been completed and this distance is one mile less than two thirds of the entire length of the highway. To solve this problem, we need to write an equation using the given information and solve for the variable representing the total length of the highway.

Let's denote the total length of the highway as 'x'. According to the problem, two thirds of this length minus one mile equals 37 miles. Forming an equation, we can write (2/3)x - 1 = 37.

To solve for 'x', first add 1 to both sides of the equation to get rid of the '-1' on the left, that gives us (2/3)x = 38. After, to completely isolate 'x', multiply both sides of the equation by the reciprocal of 2/3, which is 3/2. Doing this results in 'x' = 38 * (3/2) = 57 miles.

Therefore, the new highway will be 57 miles long when complete.
