Step-by-step explanation:
- <em>Assuming copper sulfate has same density as water</em>
<u>Chemical to water ratio as per given is:</u>
- 250 kg : 1000 liter = 1 kg : 4 liter
Lab solution is 350 ml
<u>Converting to same ratio as above:</u>
350/(1 + 4) = 70 ml
- 70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 ml
Answer is 0.07 kg
The distance traveled by the Salmon is proportional to the duration spent
swimming.
A table of the distance traveled by the Atlantic Salmon is presented as follows;

Reasons:
The given parameter are;
The steady rate at which Atlantic Salmon swims = 2 miles in 3 minutes
Distance the Salmon swims, d ∝ Time taken, t
Therefore;
d = s·t
Where;
s = The constant of proportionality = The speed
Which gives;

The speed with which the Atlantic Salmon swims per minute is therefore;

The distance travelled, <em>d</em>, is given as follows;

A table showing the distance travelled by the fish with time is presented as follows;

Answer:
D is incorrect
Step-by-step explanation: A is correct because there are 12 cars and 7 trucks. B is correct because there are 7 trucks and 12 cars. C is correct because there are 12 cars and 19 total vehicles(7+12=19). D is incorrect because while there are 7 trucks, there are not 12 vehicles in TOTAL.
