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:
.
Answer:
A
Step-by-step explanation:
There is/are :-
- 1 real zero
- 3 complex zeros
75 represents the total minutes spent running and biking
<h3>How to interpret the equation?</h3>
The given parameters are:
- x = number of minutes spends running
- y =number of minutes biking
The equation is given as:
x + y = 75
The above means that when the minutes spent running and the minutes spent biking are added, the total is 75
Hence, the 75 represents the total minutes spent running and biking

Step-by-step explanation:
Answer:
17:7
Step-by-step explanation:
The first jar is 2/3 water, and the second jar is 3/4 water. Since the jars are equal volume, the resulting mixture will be the average.
(2/3 + 3/4) / 2
(8/12 + 9/12) / 2
(17/12) / 2
17/24
If the jar is divided into 24 parts, 17 parts are water, and the remaining 7 parts are vinegar. So the ratio is 17:7.
