75% of the whole length is 30 cm
(30x100)/75=40cm
So a=40 cm
Answer:
x * (rate of calories burned) = y
Step-by-step explanation:
The independent variable is the one that isn't being affected and therefore represents the time that Sabir walks and the number of calories he burns. Therefore, we can multiply x by the rate of calories burned to get y. The rate is not provided.
Answer:
The answer is 
Step-by-step explanation:
In order to determine the answer, we have to know about equation. In an equation, we have variables, some of them depend on the others. If we want to know the value of one variable ( the dependent variable), we have to free it in any side of the equation.
In this case, we want to know the value of "L" variable. So we free that variable to the right side of the equation.
We divide each side by "W":
We simplify the "W" in the right side:
Finally, the solution for "L" is :
The number of minutes that would make the water level be less than or equal to 64 cups is;
160 minutes.
We are given the equation;
W = -0.414t + 129.549
where;
t is the number of minutes
W is the level of water
The expression to find the amount of time it will take for the water level be less than or equal to 64 cups is;
-0.414t + 129.549 ≤ 64
Using substitution property of equality, subtract 129.549 from both sides to get;
-0.414t + 129.549 - 129.549 ≤ 64 - 129.549
-0.414t ≤ -65.549
Using division property of equality, divide both sides by -0.414 to get;
t ≤ -65.549/-0.414
t ≥ 158.33
(sign changed to ≥ because we divided the inequality by a negative number.)
We have to approximate the inequality to get;
t = 160 minutes.
