Answer: after 40 seconds, the two tanks will have the same amount of water.
Step-by-step explanation:
Let x represent the number of seconds after which both tanks will have the same amount of water.
A fish tank has 150 gallons of water and is being drained at a rate of 1/2 gallons each second. It means that the number of gallons of water that would be in the tank after t seconds is
150 - 0.5t
A second fish tank has 120 gallons and it is being filled at a rate of 1/4 gallons each second. It means that the number of gallons of water that would be in the tank after t seconds is
120 + 0.25t
For the volume of both tanks to he the same, then
120 + 0.25t = 150 - 0.5t
0.25t + 0.5t = 150 - 120
0.75t = 30
t = 40 seconds
Answer:
2:15 p.m.
Step-by-step explanation:
Starting time 1:40 p.m.
Time on subway <u>+0:17
</u>
Time off subway 1:57 p.m.
Time walking <u>+0:18
</u>
Time at apartment 1:75
When the minutes are more than 60, you subtract 60 from the minutes and add 1 to the hours.
1 :75
+1<u> - :60
</u>
2 :15 p.m.
Daniel arrived at the apartment at 2:15 p.m.
A= c+4+12
a= c+16
a+c= c+16+c+16-16= 2c+16
We can start by separating the x^3, and that means we have to multiply both sides by 4, resulting in x^3=27. Next, we can find the cube root of both sides ( as x is the cube root of x^3), getting x=3
