Answer:
F = 160 pounds
B. 160 pounds
Step-by-step explanation:
F = k / l
Where,
F = amount of force needed
l = length of the lever
k = constant of proportionality
F = 240 when l = 24 inch
F = k / l
240 = k / 24
Cross product
240*24 = k
k = 5,760
Find F when l = 36 inch
Recall, k = 5,760
F = k / l
= 5,760 / 36
= 160
F = 160 pounds
The correct answer is B. 160 pounds
Answer:
94
Step-by-step explanation:
Since the circle equals to 142 degrees you have to subtract the already given umber (48) by the total amount and it'll give you the missing angle which is 94.
