The answer is 11
242/2 is 121 then the square root of that is 11
Answer:
-47
Step-by-step explanation:
To find the answer, you need to find the pattern.
Each term of the sequence is decreased by an odd number in a pattern of (-1, -3, -5, -7, -9, -11, -13...)
So:
2 - 1 = 1 (second term)
1 - 3 = -2 (third term)
-2 - 5 = -7 (fourth term)
-7 - 7 = -14 (fifth term)
-14 - 9 = -23 (sixth term)
-23 - 11 = -34 (seventh term)
-34 - 13 = -47 (eighth term)
Answer:
I think 13 is C
Step-by-step explanation:
71+52= 123
180-123= 57

Step-by-step explanation:
The question is incomplete, as there are lots of missing details in the question. To do this, I will make assumptions
See attachment for question illustration where
the height of the second floor
the distance where the base of the ladder is placed
the length of the ladder
So, we are to solve for x.
Using Pythagoras theorem, we have:
Make the subject
Take square roots of both sides
The above is the expression to calculate the base length of the ladder.
Assume
So, we have:
