For this case we have the following equation:
w = || F || • || PQ || costheta
Where,
|| F ||: force vector module
|| PQ ||: distance module
costheta: cosine of the angle between the force vector and the distance vector.
Substituting values:
w = (60) * (100) * (cos (45))
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.640687 lb.ft
Answer:
x = 51
Step-by-step explanation:
(x-3) /4 = 12
Multiply each side by 4
(x-3) /4 *4 = 12*4
x-3 = 48
Add 3 to each side
x-3+3 = 48+3
x = 51
1 + 1x
OR
1 + x
They mean the same thing! Hope this helps!
Answer:
C: 8.00
Step-by-step explanation:
1 in = 2.54 cm
l = 20.32 × 1/2.54
l = 8.00 in
The length of Nancy’s mirror is 8.00 in.
