Answer: 6
Step-by-step explanation: Process of elimination, 12 seems fairly bigger than it so we cross that out and everything above, now all that’s left is 6 and 10, 10 + 2 is 12 so no, but 6 +2 = 8 so that is your answer.
This math is known as permutations- the arrangement of a set of objects. A way that I use to solve these problems was by just multiplying the numbers, so the singer's can be selected in 28 ways.
Heyyyyyyyyyy! I think 1 of each because- y’a I just think that.
The ladder resting against the house forms a triangle similar to the one in the image below
To answer this question you must use Pythagorean theorem
a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = x
b = 8
c = 34
^^^Plug these numbers into the theorem
solve for x
+ 64 = 1156
Subtract 64 to both sides
= 1092
Take the square root of both sides
x = √1092
This can be simplified to:
2√273
or
x ≈ 33.045...
The ladder reached roughly 33.05 ft up the wall of the building
Hope this helped!
