Answer:
55 8/39 N ≈ 55 N
Step-by-step explanation:
The net force on the 1.4 kg block is proportional to its mass. That is, the ratio of net force on that block to the net force on the total mass is the same as the ratio of the block's mass to the total mass.
net force on 1.4 kg = (1.4 kg)/(1.4 +6.4 kg) × (64 N -15 N) = (7/39)(49 N)
net force on 1.4 kg = 8 31/39 N
Then the force applied by the 6.4 kg mass is ...
64 N - 8 31/39 N = 55 8/39 N ≈ 55 N . . . . applied by 6.4 kg mass
Answer:
x = -9/4
Step-by-step explanation:
First multiply 3 on both sides. One side will be -9 and the other 4x. Then divide 4 on both sides to get x = -9/4 or in decimal form x = -2.25
To find the mean of something you are finding the average, so add all the times they were late to school. Then divide by the number of numbers you had to add. You will have your answer by doing that. What it means to interpret your answer is to explain it.
