Answer:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.

Answer: 1 teashirt=7 L
1 hat= 3L
Step-by-step explanation:
2 T shirts= 31 - 17
2 T shirts= 14
1 T shirt=14/2
1 T = 7 L
14L+ 1H=17 L
one hat = 17 - 14=3 L
Answer:
b and c
Step-by-step explanation:
The Triangle Inequality Theorem lets us know that the sum of the two shortest sides of the triangle must be greater than the third side of the triangle.
In both A and D, the sum of the shortest two sides are equal to, not greater than the third side, so they will not form a triangle.
In B, 12+20 is 32, which is greater than 25. And in C, 18+24 is 42, which is greater than 30, so they both will form a triangle.
11/50=1.1/5=0.22
They are indeed equivalent.
