Answer:  2</h3>
========================================================
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:
w = 4 cm
Step-by-step explanation:
recall that the area of a triangle is given by 
A = (1/2) x base length x height
we are given:
A = 10 cm²
base length = 5 cm
height = w
substituting the values above into the equation, 
A = (1/2) x base length x height
10 = (1/2) x 5 x w
20 = 5w
w = 20/5
w = 4 cm

Choices: <span>A. 16/9
B. 4/3
C. 32/9
D. 64/27</span>
Given:
number of pints used for larger chest = 16 pints
number of pints used for smaller chest = 9 pints
Ratio of the volume of the larger chest compared to the smaller chest.
We will use the number of pints used in lieu of the volume of each chest.
16 / 9 is the ratio. Choice A.
        
             
        
        
        
Patty because she has the lowest time out of them all. From least to greatest Patty would be the least with her time being shorter than the rest
