Answer:
56
Step-by-step explanation:
Let the x be the amount of money Maria had.
3/7 + 1/4 + 1/8 = 45/56
She spend 45/56 of x.
∴ 45/56 × x = (45/56)x
1 - 45/56 = 11/56
(11/56)x is the money that was left.
This is equivalent to 11.
(11/56)x = 11
11x = 11×56
11x = 616
x = 616/11
= 56.
Maria had #56.

Answer:
Work done = 3750 Joules
Step-by-step explanation:
The force acting in the body should be resolved to it's horizontal component before we can use ut to solve for the problem
Horizontal component= 150 * cos 60
Horizontal component= 150*0.5
Horizontal component= 75N
Work done= Force * distance
Work done= 75*50
Work done= 3750 Nm
Work done = 3750 Joules
