The population of Mexico in 2000 was approximately 103,970,000 and the land area was 761,700 square miles. The population increased by 13.4% in 2010. To the nearest whole number, how much was the population density, in people per square mile, increase in 2010?
Answer: 19 people per sqaure mile
Step-by-step explanation:
Given : Population in 2000 = 103,970,000
The population increased by 13.4% in 2010.
Population in 2010 = 103,970,000 + 13.4% of (103,970,000)
= 103,970,000+ (0.134)(103,970,000)
= 103,970,000(1+0.134)
=103,970,000(1.134)
=117,901,980
In 2000,
Population density= [tex]\dfrac{\text{Population}}{\text{Area}}[/tex]
[tex]=\dfrac{103970000}{761700}\approx 136\text{ people per square mile}[/tex]
In 2010
Population density = [tex]\dfrac{\text{Population}}{\text{Area}}[/tex]
[tex]=\dfrac{117901980}{761700}\approx155\text{ people per square mile}[/tex]
Difference = 155-136 = 19 people per sqaure mile
Hence, the increase in population density in 2010 = 19 people per sqaure mile

Find the square of 7-2v10.
Answer:
89 - 28v10 = 0.456
Step-by-step explanation:
(7-2v10)² = 7² - 2*7*2v10 + (2v10)²
(7-2v10)² = 49 -28v10 + 40
(7-2v10)² = 89 - 28v10

The area of a rectangular pool is given by the trinomial 2y2 + 5y – 42. What are the possible dimensions of the pool? Use factoring.
A. 2y + 7 and y – 6
B. 2y – 2 and y + 6
C. –2y – 7 and –y – 6
D. 2y – 7 and y + 6
Answer:
D is your answer
Step-by-step explanation:
(2y-7) (y+6) that is my answer and it matches with D promise 100%
The possible dimensions of the pool are the factors of the trinomial, which are:
2y - 7 and y + 6
The correct answer is (D).
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find the possible dimensions of the pool, we need to factor the trinomial 2y² + 5y - 42.
We can start by looking for two numbers that multiply to -84 (the product of the first and last coefficients of the trinomial) and add up to 5 (the middle coefficient of the trinomial).
Those numbers are 12 and -7, because 12 x -7 = -84 and 12 + (-7) = 5.
Using these numbers, we can rewrite the trinomial as:
2y² + 12y - 7y - 42
Now we can factor by grouping:
(2y² + 12y) - (7y + 42)
2y(y + 6) - 7(y + 6)
(2y - 7)(y + 6)
So the possible dimensions of the pool are the factors of the trinomial, which are:
2y - 7 and y + 6
Therefore,
The possible dimensions of the pool are the factors of the trinomial, which are:
2y - 7 and y + 6
The correct answer is (D) 2y - 7 and y + 6.

Find the area of a regular polygon that has 15 sides and a perimeter 120ft.
Please answer fast
Answer:
Let 's' be the length of a side of the polygon.
Then,
perimeter = 15s
or, 120 = 15s
or, s = 8ft.
The area of regular polygon having 'n' number of sides with each of length 's' is given by:
A = [tex][{\frac{s}{2tan(\frac{180}{n}) }} (n)(s)]^{2}[/tex]
According to question,
s=8ft, n = 15
Therefore, Area = [tex][\frac{8}{2tan(\frac{180}{15}) }(15)(8)] = [\frac{480}{2tan(12)}] = (240cot12)[/tex] ≈1129.11sq. ft
Five hundred tickets were sold for a Saturday evening performance of a play. The tickets cost $ 7.50 for adults and $4.00 for children. A total of $3312.50 was received for all the tickets sold that Saturday evening. How many adults attended the play.
Answer: A+C=500
7.5A+4.75C=3351.25
C=500-A
7.5A+4.75(500-A)=3351.25
7.5A+2375-4.75A=3351.25
2.75A=976.25
A=355 adults ($2662.50)
C=500-A=145 children ($688.75)

Answer:
The birch tree needs 12 years
Step-by-step explanation:
Proportional Relationship
Two variables t and d are proportional if they have the relationship described by the equation:
d = kt
Where k is the constant of proportionality.
From the graph on the question, we recognize the proportionality of the age of a birch tree and its diameter because the line passes through the origin (0,0). To find the equation, we need to recognize a clear point on the graph. We select the point (2,7). Substituting in the equation:
7 = 2k
Thus:
[tex]k=\frac{7}{2}[/tex]
The equation is:
[tex]\displaystyle d=\frac{7}{2}t[/tex]
For the birch to have a diameter of d=42 inches, the time needed can be calculated by solving the equation:
[tex]\displaystyle 42=\frac{7}{2}t[/tex]
[tex]\displaystyle t=42*\frac{2}{7}[/tex]
t = 12 years
The birch tree needs 12 years
