For this case we have the following equation:
w = F • PQ
Where,
w: work done
F: is the force vector
PQ: is the vector of the direction of movement.
Rewriting the equation we have:
w = || F || • || PQ || costheta
Substituting values:
w = (60) * (100) * (cos (45))
w = (60) * (100) * (root (2) / 2)
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.6 lb.ft

Each T shirt costs $21.
Since Martha takes her niece and nephew to a concert, and she buys T-shirts and bumper stickers for them, and the bumper stickers cost $ 1 each, and Martha's niece wants 1 shirt and 4 bumper stickers, and her nephew wants 2 shirts but no bumper stickers, to determine, if Martha's total is $ 67, what is the cost of one shirt, the following calculation must be performed, posing linear equations:
- 1 bumper sticker = $ 1
- 1 T shirt + 4 bumper stickers + 2 T shirts = $ 67
- 1X + 4 x 1 + 2X = 67
- 3X = 67 - 4
- X = 63/3
- X = 21
Therefore, each T shirt costs $21.
