Answer:
20,000 per sq. km.
Step-by-step explanation:
In this question, the variable k represents the total number of people in a single square km. Since we are provided both the total number of the population and the total square kilometers of the land, we can calculate the value of k by dividing the population size by the total land. Therefore, the calculation would be the following...
[tex]\frac{10,400,000 people}{520km^{2} }[/tex] = k
20,000 per sq. km. = k
Finally, we can see that the value of k is 20,000 per sq. km.

Answer:
10
Step-by-step explanation:
10 is the greatest common factor that you can divide into both 40 and 50.
Answer:
10
Step-by-step explanation:
Try and find the prime factorization of 40 and 50.
40=2*2*2*5
50=2*5*5
Multiply the prime factors that are common to both numbers.
2*5=10
In the diagram, AC is a diameter of the circle with center 0. If m ZACB = 50°, what is ZBAC?
OA 50°
OB. 40°
O C. 80°
OD. 100°
Answer:
40degrees
Step-by-step explanation:
Find the diagram attached
Since the triangle ina semi circle is a right angle, hence <B = 90degrees
Also frm the diagram
<A + <B + <C = 180
<A + 90 + 50 = 180
<A + 140 = 180
<A = 180 - 140
<A = 40degrees
Hence the measure if m<BAC is 40degrees
One of two complementary angles is 35° larger than the other. What is the measure of both angles?
Answer:
Since the two angles are complementary, they add up to 90...
If we call the first one x, then the other must be 90-x...
Since they are 35 different, we write
x = (90 - x) + 35
now solve, and get
x = 90 - x + 35
x = -x + 125
2x = 125
x = 62.5 deg
the other must be
90 - 62.5 = 27.5 deg

According to Home Water Works, the average American shower uses 17.2 gallons and lasts about 8.2 minutes. To the nearest tenth of a gallon, how many gallons will Louise use when taking a 15-minute shower? Answer in complete sentences.
ALL GIVE BRAINLY!!!
Answer:
Home Water Works says that in most homes, showers are the third-largest user of water after toilets and clothes washers. The average American shower water usage is 17.2 gallons with the average shower length being 8.2 minutes. The average flow rate is 2.1 gallons per minute.
Answer:
90.2 gallons
Step-by-step explanation:
This is because if we take 8.8 * 8.2=72.16
then we do 72.16*5 =360.8
360.8 / 4 = 90.2 gallons.

Answer:
1. the side length of the square is 3 when its perimeter is 12.
2. (20/21, 5/21)
Step-by-step explanation:
2. 20/21 ÷ 4 = 20/21 × 1/4 = 5/21(the side length of the square with the given perimeter of 20/21)
=> (20/21, 5/21)
Aubrey filled her pool 0.9 of the way with water. Water evaporated from the pool at a rate of 7.5ft ^ 3 per day.
Answer: hello your question lacks vital data hence I will provide you with a general equation within the scope of your question
answer :
General equation = ( Stiver and Mackay or EPA ) evaporation equations
E = [tex]\frac{PAW}{T +459.67}[/tex] or E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]
Step-by-step explanation:
Given data
volume of water in pool = 0.9 i.e. 90% full
rate of evaporation = 7.5ft^3 per day = 56.1039 gallons / day
Assumption :
Volume of pool = 16,000 gallons
In order to resolve the missing part of the problem apply the equation below
E = [tex]\frac{PAW}{T +459.67}[/tex] or E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]
where : E = Evaporation rate , P = water's vapor pressure , A = pool surface Area , W = wind speed , T = Temperature in Fahrenheit

Which greatest digit should replace n so that the number 342n84 is divisible by 3?
Answer:
9
Step-by-step explanation:
If you want the number to be divisible by three make sure the sum of all the numbers are divisible by three. Add all the numbers you have to see what they make.
3+4+2+8+4=21
So we just need to find the greatest number we can add to that to have it remain divisible by three. A number divisible by three is 30, and we can add 9 to 21 to make 30. Of course, there are other numbers we could add, but nine is the largest one-digit number that would work. Other smaller numbers include 3 and 6.
3+4+2+8+4+9=30
Now we check to see if our number is divisible by three
342984÷3 = 114328
114328 is a whole number so we know it's divisible.

Find the equation of the line passing
through the points (3,-2) and (4, 6).
y = 8x + [?]
Step-by-step explanation:
1.) Plug in one of the points.
y = 8x + b
6 = 8(4) + b
2.) Solve for b (or [?])
[tex]6 = 32 + b \\ - 32 \: \: \: \: \: \: \: \: \: - 32[/tex]
32 cancels out on the right side.
Subtract 32 from 6, which is -26
3.) -26 = b
4.) Check with other point:
-2 = 8(3) + b
-2 = 24 + b
Cancel out 24 on the right side: 24-24 = 0
-2 - 24 = -26
-26 = b
Which function is graphed below?
f(x) = –cos(x)
f(x) = cos(x)
f(x) = sin(x)
f(x) = –sin(x)
The function whose graph is plotted below is given by: Option B:f(x) = cos(x)
How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The missing graph is attached below.
It is either sine or cosine (as known from the options).
The sin function is 0 at x = 0, so we're sure the function isn't sin or negative sin as 0 would make it fall on 0.
The function is definitely [tex]\cos(x)[/tex] since at x = 0 it is 1 and at x = [tex]\pi[/tex] it is -1 (while if it would be -cos(x), it would be -1 at x =0 and 1 at x = [tex]\pi[/tex] )
Thus, the function whose graph is plotted below is given by: Option B:f(x) = cos(x)
