Yea I agree with both of them as 1/4 and 25/100 is the same as 25%. As you can put 25 percent in a fraction form as they both used for example 1/4,2/8 or even 25/100.
Are you really having trouble counting the blocks ? It shouldn't be
a problem, because you can <em>see</em> all of them in the picture. There are
no blocks hiding behind other ones.
There are 5 blocks in the bottom row, sitting on the table, and
4 more stacked on top of them . . . total of 9 blocks.

Answer:
13. (A, b, C) = (30.66°, 91.042, 25.34°)
14. insufficient information
Step-by-step explanation:
13. The Law of Cosines can help you find the side opposite the given angle. Then that can be used with the Law of Sines to find the other angles.
b = √(a² +c² -2ac·cos(B)) = √(56² +47² -2(56)(47)cos(124°)) ≈ √8288.59
b ≈ 91.042
__
A = arcsin(a/b·sin(B)) ≈ arcsin(56/91.042·sin(124°)) ≈ 30.66°
C = 180° -124° -30.66° = 25.34°
The missing dimensions are (A, b, C) = (30.66°, 91.042, 25.34°).

14. One side and one angle do not define a unique triangle. There is insufficient information to find f.
15 more than half -12 = 9 or -6 + 15 = 9
Step-by-step explanation:
x = the number
2x - 25 = x
2x = x + 25
x = 25
