Answer:
Correct answer would be 84/12=7
Step-by-step explanation:
Reason being , Its asking the "product" Of Julies score (7)
If you divide 84 /7 it will be =12
since its already giving you what its equal you would flip it and it would be 84/12
Answer:
Step-by-step explanation:
A large aquarium has a length of 84 inches. It is located in a large basement that is properly heated and ventilated. The width should be close to 1/2 the length and the height ought to be 1/6 the length. If the fish tank requires that an aerator be placed every 28 inches along the back edge, how many aerators are needed. Note: an aerator is not placed in either corner.
Width =_________________
Height= ________________
Aerators = ______________
Find the number of cubic inches of the fish tank. If an aerator will provide enough oxygen to aerate 5 cubic feet,, do you have enough aerators for the fish to live comfortably? If the answer is no, then how many aerators do you need?
Answer:
1/6
Step-by-step explanation:
In a game of "Rock, Paper, Scissors", there are three possibilities. The probability that Marilyn will get Paper is given as
1/3
In a coin flip, the probability that it will land on tails is
1/2
Therefore, the probability that she will win if she predicts "Paper" and calls Tails is the product of the individual probabilities:
1/3 * 1/2 = 1/6
Answer:
The work has Been done is 2503.12 J .
Step-by-step explanation:
Formula for workdone is given by
Workdone = Force × Distance
As w = mg
Where m is the mass , g is the acceleration of gravity .
As given
Ben Pumpiniron applies an upward force to lift a 129-kg barbell to a height of 1.98 m at a constant speed.
m = 129 kg
g = 9.8 m / s²
Putting in the w =mg
w = 129 × 9.8
= 1264.2 kg m / s²
(As given in the question force is constant thus force doing the work is equal to weight .)
Thus
Force = 1264.2 kg m / s²
Workdone = Force × Distance
= 1264.2 × 1.98
= 2503.12 J (Approx)
Therefore the work has Been done is 2503.12 J .
