Answer:
20 mg / hour
Step-by-step explanation:
The first step is to find the mg/mL of dopamine.
If there are 52 mg / 26 mL, then there are 2 mg / 1 mL (just reduce the fraction).
If we are losing 10 mL / 1 hour, and there are 2 mg / mL, then the flow rate of dopamine mg / hour is 20.
You can also do this using dimensional analysis.
Just cross out the units that cancel in the numerator and denominator (mL in this case), and you're left with mg / hour. Then multiply the numerators and divide by the denominators. You get the same answer.
(7t-2) - (-3t+1) = -3*(1-3t)
First distribute:
7t-2+3t-1 = -3+9t
Now get all the terms with 't' on the same side by subtracting/adding:
7t+3t-9t = -3+2+1
Combine the terms:
1t=0
t=0
Check:
Plug in 0 for t and see if both sides of the equation come out the same:
Does (7(0)-2) - (-3(0)+1) = -3(1-3(0)) ?
(-2) - (1) = -3(1) ?
-3 = -3 ?
Yes! It works, so t=0!
Answer:
Your answer would be 24 but then if you round it to the nearest tenth the you would have 20

20% also equals 1/5, right?
So in order to find the total number of turtle nests, just find 5/5, or multiply 15 by 5.
15 x 5 = 75
There were 75 total nests
