Answer:
19.2 lbs of dog food in 5 weeks
Step-by-step explanation:
12 divided by 5 is 2.4
So that means each week the dog consumes 2.4 lbs of food each week.
If we want to see how much he eats in 8 weeks, we'd multiply 2.4 by 8, giving us 19.2
Answer:
c. P=R-10; 35 million
Step-by-step explanation:
P=R-10, just read what the text says, namely profit = revenue - expenses
P=25, 25=R-10 <=> R=35
I don’t understand what the question is
Answer: no solution or zero solutions.

Answer:
Step-by-step explanation:
To find the number of kilograms of mercury we need to find how to relate density, mass and, volume. For this we shall recall the density formula:
where 
is the density, 
is the mass and, 
is the volume.
We have the density and want to compute the mass so now we want to know the volume of the pool.
The volume of a rectangular pool is given by the fomula:
.
So for our pool
.
.
Our density is in 
, so the last thing we need to do before computing the mass is to express the density in 
(this is because we want our mass in 
and, we have our volume in 
).
For the density conversion we have to remember that
so
.
With this we can finally compute mass:
.
