The mechanical advantage of an inclined plane is 10. The length of the ramp is 44 m. The inclined plane is used to lift a fridge, with a mass of 82 kg, to a height of 4 m. a). How much force would a mover need to apply to get the fridge up the inclined plane(use 9.81 m/s2 as the acceleration de to gravity)? b). What is the efficiency of the inclined plane? (Please show your work!)

thank you!

Step-by-step explanation:

i try really i think the answer is 488 i dont know

Step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
