ABC is a 30 60 90 triangle
In such a triangle, the shortest side AB multiplied by the square root of 3 equals the length of the "medium" side CB.
6 * sq root (3) = 10.39
(Incidentally, the hypotenuse AC = short side*2 = 12)
Here is the correct step:
7(6)÷5+42
=42÷5+42
=8.4+42
=50.4
We see that Line 2 is incorrect because Line 1 showed us this “ 7(6)÷5+42 " but line 2 show us different expression 7(6)÷5+16. As a result, Line 2 is the final answer. Hope it help!
11/26 chance that the student plays both instruments.
First, add the amount of students that just play flute or piano:
3 + 5 = 8
Then add 8 to the amount that does not play either instrument:
8 + 7 = 15
Then do:
26 - 15 = 11
Then place 11 over the amount of people:
11/26
