A number has only 1 factor pair. One of its factors is twice the other factor. What is the number? Explain.
Please help me with this question. I will give brainliest ONLY if two people answer. Plz and thx :D
========================================================
Explanation:
If a number only has one factor pair, then that number must be prime. This is because prime numbers only have factors of 1 and the number itself.
For instance, the value 7 is prime because the only factors of this are 1 and 7.
For something like the number 32, it is composite and not prime because it has the factors {1,2,4,8,16,32} and it leads to these three factor pairs: 1*32, 2*16, 4*8. This is one example showing why the answer isn't composite.
-----------
Let's say that p is the unknown prime we want to find. The factors of this are 1 and p. We're told that "one of the factors is twice the other factor", so that must mean p = 2*1 = 2. We can see that 2 is twice that of 1.

Answer:
use m a t h w a y
really easy to use
works for all algebraic equations
Step-by-step explanation:
I assume you're trying to simplify these.
For all of these, divide the coefficients separately from the x's and that separately from the y's.
#5: [tex]\dfrac{16t^4}{8t}[/tex]
Start with 16/8 = 2.
Then move to [tex]\dfrac{t^4}{t}[/tex].
[tex]\dfrac{t^4}{t} = \dfrac{t \cdot t \cdot t \cdot t}{t}[/tex]
So, you'll cancel out one t from the top with the one t in the bottom and be left with [tex]t^3[/tex].
Putting that all together:
[tex]\dfrac{16t^4}{8t} = 2t^3[/tex]
#6: [tex]\dfrac{x^6y^{14}}{x^4y^9}[/tex]
You have 6 x's in the top and 4 x's in the bottom. When you cancel out 4 from the top to cancel the 4 in the bottom, you'll be left with 2 x's in the top:
[tex]\dfrac{x^6}{x^4}=x^2[/tex]
Similarly, 14 y's up top and 9 in the bottom. When you cancel one-for-one, you'll be left with 5 y's up top:
[tex]\dfrac{y^{14}}{y^9}=y^5[/tex]
Putting that all together:
[tex]\dfrac{x^6y^{14}}{x^4y^9}=x^2y^5[/tex]
#7: [tex]\dfrac{3^4x^4}{3x^2}[/tex]
This is the same as #6, just with 3's and x's.
You have four 3's up top and one in the bottom. When you cancel, you'll be left with three 3's up top:
[tex]\dfrac{3^4}{3}=3^3[/tex]
You have 4 x's up top and 2 x's down below. That will leave 2 x's up top once you cancel them out:
[tex]\dfrac{x^4}{x^2}=x^2[/tex]
Putting that together:
[tex]\dfrac{3^4x^4}{3x^2}=3^3x^2[/tex]

Find the perimeter of the figure to the nearest hundredth. Sorry to ask ANOTHER question on this stuff but I'm doing an assignment and I don't get it-
Answer:
I did my best, but it has been a while. I really hope that this helps
Step-by-step explanation:
so you can find the perimeter of a circle
-----The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle, you need to go halfway around the circle and then across a diagonal to get back to where you started, so the perimeter is 1/2 π × d + d.

A scale model of an airplane has a wingspan of 8 inches (in). In real life, the same airplane has a wingspan of 32 feet (ft). What is the scale of the model to real life?
Answer:
The ratio would be 8 inches to 384 inches. You can write it as 8/384. If you simplify it, it would be 1/48.

There are 12 gray marbles in a jar and eight white marbles. What percent of marbles are white. Explain answer pls.
Answer:
40 %
Step-by-step explanation:
8/20 is 40% and 12/20 is 60%
AWNSER:
40%
EXPPLENATION:
1. you need to find how many marbles are in the bag in total. e.g.(20)
2. find out how many of the marbles are blue and put it into a fraction blue/total number of marbles. e.g.(8/20)
3.multiply the fraction so that you have 100 as your denominator since 'per-cent' means out of 100. e.g.(8/20 x 5= 40/100)
4. remove the fraction/ take off the 100 and your done
