In physics, work is equal to the product of force and distance, given that the direction of force is the same with the direction of the distance.
W = Fd
The total force is
F = 1,700 N + 500 N = 2,200 N
Now, if the question is the work needed to lift the barbell from the ground, the distance would be 2 m. Hence, the work would be
W = (2,220 N)(2 m) = 4,400 N·m or 4,400 J
The given ratio of powder to water is 3:2 based on weight for Kool-aide. It is also given that 120g of flavored powder is needed for a certain amount of Kool-aide.
Let us assume that the amount of water (by weight) required to maintain the given ratio of 3:2 be represented by the letter 
. Thus, from the given information we can conclude that:
Cross-multiplying we get:
grams.
Thus, the amount of water in grams in that Kool-aide is 80 grams.
We know that the puppy weights 56 ounces and it tells us that 1 pound = 16 ounces so every 16 ounces we have a pound. It wants to know how many pounds does the puppy weights. 56 / 16 = number of pounds. So 56 divided by 16 = pounds. The puppy weights 3.5 pounds
For the last question
40*3=120 total cakes
120*.15=18 chocolate cakes
