Answer:
Step-by-step explanation:
Given that water leaks from a vertical cylindrical tank through a small hole in its base at a rate proportional to the square root of the volume of the water remaining. The tank intitially contains 300 liters and 23 liters leak out during the first day
Let V represent the volume at time t.
Rate of change of V is 
where k represents the constant of proportionality
We separate the variables and integrate
Use the fact when t =0, V =300
Now use the fact when t =1 V= 300-23 = 277
k is negative because there is leak
So equation is
Using this
A) when half empty V = 150
t = 
so it takes 3.75 days
B) When t =3
V = 233.7515
Answer:
Complete percentage of tape = 150%
Step-by-step explanation:
Given:
Two parts shows 100%
Total number of parts = 3
Find:
Complete percentage of tape
Computation:
Complete percentage of tape = 100%[3/2]
Complete percentage of tape = 150%

Answer:
y=70 degrees
Step-by-step explanation:
If 2 angles are complimentary, they add up to 90 degrees.
x+y=90 degrees
x=20 degrees
y=90-20 degrees
y=70 degrees
If that is wrong, try this. Let's say the questions gives us the fact that x is 20 degrees greater than y.
y=x
Substituting x for y, the equation is x+x+20=90
Since y is x, x would also be y, which is 35. then x+20 would be 55.
So y would be 35.
THE ANSWER WOULD BE <u><em>70 DEGREES</em></u>, BUT IF THAT IS WRONG, DO THE SECOND ONE, WHICH IS 35
Answer:
The average distance from venus to mars is 2.5x10⁸ kilometers.
Step-by-step explanation:
We know:
d₁: average distance between venus and earth = 2.5x10⁷ km
d₂: average distance between mars and earth = 2.25x10⁸ km
We can find the average distance from venus to mars as follows:
First, we need to equal the base power 10 so we can sum both distances:
Now, average distance:
Therefore, the average distance from venus to mars is 2.5x10⁸ kilometers.
I hope it helps you!
