Answer:
51
Step-by-step explanation:
A = Surface area of the Earth = [tex]1.5\times 10^8\ \text{km}^2[/tex]
Total number of people on Earth = 7.594 billion as of 2018 = [tex]7.594\times 10^9[/tex]
We need to find the number of people living in each square km of land area.
So, we need to divide the number of people by the land area of the Earth.
[tex]1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}[/tex]
[tex]\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}[/tex]
[tex]\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}[/tex]
So, 51 people will inhabit each square km of land area.

Answer:
A. 228.5
B. 10
Step-by-step explanation:
A. Since x represents the number of months, replace x with 6 in the equation. Then multiply 29x6, which equals 174. Then add 174+54.5, which equals 228.5.
B. You need to solve for x by switching the signs in the equation. Set the original equation (29x+54.5) equal to 344.50. To solve for x, first subtract 344.50-54.5, which equals 290 (you subtract because it's the opposite of adding). Then divide 290÷29, which equals 10. You can check your work by replacing x in the original equation with 10, and if you get 344.5, your answer is correct.

one type of insect is 0.0052 meters long. what is this length in scientific notation?
Answer:
Because scientific notation has to be in between 1 and 10, you would need this to be 5.2. Count the spaces and since its getting smaller your exponent is negative.
Your answer should be 5.2*10^(-3)

If F, G, and H are the midpoints of the sides of triangle JKL , FG = 37, KL = 48, and GH = 30 find each measure
Answer:
The measure of JK is 60
Step-by-step explanation:
It is given that the points F, G, and H are the midpoints of the sides of triangle JKL , FG = 37, KL = 48, and GH = 30.
The point F is midpoint of JK, point G is midpoint of KL and the point H is midpoint of LJ as shown in figure .
According to the midpoint theorem, the line connecting the midpoints of two sides is parallel to the third and its length is half of the third si
Answer:
60

geometry, is this right if not whats the answer ?
==============================================
Explanation:
Because S and T are midpoints of segments PQ and QR, we know that ST is a midsegment of triangle PQR. Consequently, this means ST is parallel to PR.
From the same side interior angle theorem, the angles (11x-3) and (5x-9) are supplementary angles. This is only true because of the parallel lines.
So we can say the following:
(angle P) + (angle S) = 180
(5x-9) + (11x-3) = 180
(5x+11x) + (-9-3) = 180
16x - 12 = 180
16x = 180+12
16x = 192
x = 192/16
x = 12
--------------------------
Use this to find angle PST
angle PST = 11x-3
angle PST = 11*12-3
angle PST = 132-3
angle PST = 129 degrees
--------------------------
Optionally we can find angle QPR
angle QPR = 5x-9
angle QPR = 5*12-9
angle QPR = 60-9
angle QPR = 51 degrees
As a check, adding the two angles we found should get us 180
(angle PST)+(angle QPR) = 129+51 = 180
The answer checks out.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
5x - 2y = 9
3x + 4y = -5
Step 2: Rewrite systems
10x - 4y = 18
3x + 4y = -5
Step 3: Solve for x
Add to equations together: 13x = 13Divide 13 on both sides: x = 1Step 4: Solve for y
Define: 3x + 4y = -5Substitute in x: 3(1) + 4y = -5Multiply: 3 + 4y = -5Isolate y term: 4y = -8Isolate y: y = -2And we have our final answer!

C personalities are organized and controlled. They take their time completing tasks accurately, like to research things thoroughly, and are always prepared. Because they put so much time and effort into everything they do, they hate to be criticized. They are perfectionists at heart and take even the smallest complaint personally. This makes them extremely difficult to confront. The best way to approach it is to focus on parts of the problem largely out of the C personality’s control or aspects of the problem they might not have considered. Make it clear that you appreciate all of their efforts and that you’re bringing something to their attention because it’s a variable that they need to have in the equation in the future. No matter what, don’t frame the conflict as a personal attack. If you do, the C personality will likely become resentful and go out of their way to avoid future interactions with you.%%%%%%%%%%%%%%%

How do you find a unit rate for $2.50 for 5 ounces
Answer:
You divide 2.50 by 5.
So 2.50/5 makes it $0.50 per ounce.
Answer: $0.50 for 1 ounce
Step-by-step explanation:
To find a unit rate, you have to find the cost for one. When we say it's $2.50 for 5 ounces, it's for 5, not 1. So we have to divide by 5.
2.50/5= 0.5 and 5/5=1
