X is 50 because a triangle should end up being equal to 180 in total and since the top is 80 then that leaves you with 100 and then the two bottoms are the same so that makes it 50
Answer:
10
Step-by-step explanation:
11, 13, 4, 9
In order to find the median we must first arrange the numbers in order (Least to greatest)
4, 9, 11, 13
If there is 2 numbers in the middle: the median is their average
If there is only one number in the middle, that number is the median.
Since there are two numbers (9 and 11) we have to take their average.
(9+11) / 2 = 20 / 2 = 10
The median is 10!
Answer:
The answer is 2/3 and I will show the working to prove that in the explanation
Step-by-step explanation:
÷ 
×
Answer =× = 
- So basically what is happening in the above steps what I have shown is that first I am changing the division sign into multiplication and then I am reciprocating the fraction of 1/4 into 4/1 because on the other side of it is multiplying and after doing that I am simplifying the fraction 4/6 by dividing it by 2 and hence I got a fraction of 2/3 as the answer
Answer:
Step-by-step explanation:
Composite numbers are positive numbers that have factors, This means that they are divisible by numbers other than 1 and itself provided that number is a factor of the composite number. They possess at the bearest minimum level, a divisor other than 1 and itself. They are a natural number that is expressible as the product of two(or more) numbers other than 1 and itself.
For example:
4 is a composite number because its factors are 1, 2 and 4 which have another divisor apart from 1 and itself (4). That divisor is 2.
We all know that prime numbers are numbers that can be only be divided by 1 and itself.
Therefore, the sum of two composite number, for example:
4 + 6 = 10, We can now see that 10 is never a prime number.
