Answer:
560
Step-by-step explanation:
560÷210+÷90138 which makes the answer
A number is rational if it can be written in form a/b where a and b are integers and b is not equal to 0
integers are like -4,-3,-2,-1,0,1,2,3,4, etc
so
√20=2√5 which is irrational because we can't write it as a fraciton with only integers
also a rational number multilied by an irratinonal number=irrtaional
we know that the square root of any prime number will be irrational and 5 is prime so 2 times √5=rational times irrational=irrational
√20 is irrational
Answer:
22, I think
Step-by-step explanation:
You count all the squares on all of the faces.
So you count the two on the top and double it for the bottom, so four
Then, on the sides you have three so you double that and get six
Next, you double the six squares on the other side and get twelve.
Lastly, you add them up!
4 + 6 + 12
Hope this helps!
Answer:
The length of the missing segment is 24
Step-by-step explanation:
Given
The figure above
Required
Determine the missing segment
Let the missing segment be represented with x
Given that, there exist parallel lines between the two triangles;
The relationship between the sides of the triangles is as follows;
Cross Multiply
Open bracket
Subtract 15x from both sides
Divide both sides by 5
Hence, the length of the missing segment is 24
