Answer:
36x-3y+4z^2+26-7x^2
Step-by-step explanation:
Okay well for starters, you can't subtract that because it's an expression, not an equation. And secondly, there was '?' which I'm going to assue=me was a typing error.
Now to actually simplify this mess of an expression, you just need to combine the like-terms! Once you do that you really can't do anything else, since you don't know the varibles.
Answer:
Step-by-step explanation:
The easier way to figure this is by using the concept of torque in physics. If the torque of the man is greater than that experienced by the box, the lever will tilt in the man's favor (in other words, he will move down and the box will be lifted). Torque is found by multiplying the perpendicular force by the length of the lever arm. Because we want the man's torque to be greater than the box's torque, the inequality is:
and
That decimal is 6 inches in terms of meters.
180r > 76.2 so
r > .42 meters or `16.67 inches. The man has to sit at a distance greater than 16.67 inches in order for the box to be lifted by the lever.
Answer:
red segment = 25.12 ft
Step-by-step explanation:
circumference of full circle = (3.14)(24) = 75.36 ft
semi circle = 75.36/2 = 37.68 ft
60° segment = (60/360)(75.36) = 12.56 ft
red segment = 37.68 - 12.56 = 25.12 ft
