If y is directly proportional to x then y:x.
When y = 30, x = 6 then 30/6 = 5:1. Therefor for every 1x there is 5y vice versa. When x = 12, then y = 5 * 12 = 60.
Therefore y = 60 hence 60:12
Answer:
It will take 32/24, or 1 1/3 days, for 24 men to get the job done.
Step-by-step explanation:
Answer: Second option.
Step-by-step explanation:
Given the folllowing Linear Equation:

You need to substitute the coordinates of each point given in the options into the equation and then evaluate.
1) Substituting
into the equation, you get:

2) Substituting the point
. you get:

3) Apply the same procedure using the point
:

4) Apply the same procedure using the point 

5) Substituting
into the equation:

Therefore, the point
is not on the given line.
The pond will be full by the end of the day in 93 days.
<h3>Linear system</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The pond can hold 400 water liters.
y = 3.915(1.106)x is an expression.
<h3>To find </h3>
The pond will be full by the end of the day.
<h3>How many days it will take?</h3>
Let x be the day and y be the hold of water.
When pond can hold 400 liters of water the x will be
400 = 3.915×1.106x
400 = 4.33 x
x = 92.37 ≈ 93
Thus, the pond will be full by the end of the day in 93 days.
