Western North Carolina Woods have a deer population density of 3.5 deer per acre. If there are a total of 435 deer, how many acres are in this parcel of woods?
There are about 124.29 acres in this parcel woods
Step-by-step explanation:
The given is:
Western North Carolina Woods have a deer population density of 3.5 deer per acreThere are a total of 435 deerWe need to find how many acres are in this parcel of woods
∵ The population density = 3.5 deer per acre
- That means 1 acre for every 3 dears
∵ There are a total of 435 deer
∴ [tex]\frac{3.5}{1}=\frac{435}{x}[/tex] , where x is the number of acres
- By using cross multiplication
∴ 3.5 × x = 1 × 435
∴ 3.5 x = 435
- Divide both sides by 3.5
∴ x = 124.29
There are about 124.29 acres in this parcel woods

A line has a slope of -1/7 and passes through (4, -2) and (p, -1) what is the value of p
Answer:
Therefore the value of p is -3.
Step-by-step explanation:
Given a line has a slope of [tex]-\frac{1}{7}[/tex] and passes through (4,-2)and (p,-1)
The slope of a line which passes through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is
[tex]=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here [tex]x_1= 4,y_1=-2, x_2=p[/tex] and [tex]y_2= -1[/tex]
Therefore the slope of the line which passes through the given points is
[tex]=\frac{-1+2}{p-4}[/tex]
According to the problem,
[tex]\frac{-1+2}{p-4}= -\frac{1}{7}[/tex]
[tex]\Leftrightarrow \frac{1}{p-4} =-\frac{1}{7}[/tex]
[tex]\Leftrightarrow p-4=-7[/tex]
[tex]\Leftrightarrow p = -7+4[/tex]
[tex]\Leftrightarrow p = -3[/tex]
Therefore the value of p is -3.

Terry Wade's variable costs for his car
totaled $1,876.88 last year and his fixed
costs totaled $1,685. If he drove 10,846
miles last year, what was his cost per
mile? Round to the nearest cent.
A $0.45
B $0.33
C $0.64
D $0.35
To find Terry Wade's cost per mile, his variable and fixed costs are summed and then divided by the total miles driven, yielding a cost per mile of approximately $0.33.
Explanation:To calculate Terry Wade's cost per mile for using his car, we first need to add together his variable and fixed costs, and then divide this total by the number of miles he drove last year.
This gives us the cost per mile.
Step 1: Add variable and fixed costs.
Variable costs = $1,876.88
Fixed costs = $1,685
Total costs = Variable costs + Fixed costs = $1,876.88 + $1,685 = $3,561.88
Step 2: Divide the total costs by the number of miles driven.
Number of miles driven = 10,846 miles
Cost per mile = Total costs ÷ Number of miles driven = $3,561.88 ÷ 10,846 miles
Cost per mile ≈ $0.328 or rounded to the nearest cent, $0.33.
Therefore, the cost per mile for Terry Wade last year was $0.33, making the correct answer B $0.33.

If f(x) = 3x + 2 and g(x) = x^2– X, find each value.
A. g(36)
B. f(2) + 1
A) g(36) = 1260
B) f(2) + 1 = 9
Solution:
Given that,
[tex]f(x) = 3x + 2\\\\g(x) = x^2-x[/tex]
Find each value
A) g(36)Substitute x = 36 in g(x)
[tex]g(36) = (36)^2 - 36\\\\g(36) = 1296-36\\\\g(36) = 1260[/tex]
B) f(2) + 1Substitute x = 2 in f(x)
[tex]f(2) + 1 = 3(2) + 2 + 1\\\\f(2) + 1 = 6 + 2 + 1\\\\f(2) + 1 = 9[/tex]
Thus the values are found
Final answer:
To solve the functions, substitute the given values into the relevant function. After performing calculations, g(36) is found to be 1260, and f(2) + 1 is calculated to be 9.
Explanation:
To find the values for given functions, we need to substitute the relevant inputs into each function and then perform the necessary calculations.
A. g(36)
Given g(x) = x² \\- x, we substitute x with 36:
g(36) = 36² \\- 36 = 1296 \\- 36 = 1260.
B. f(2) + 1
Given f(x) = 3x + 2, we first find f(2):
f(2) = 3(2) + 2 = 6 + 2 = 8.
Now, we add 1 to f(2):
f(2) + 1 = 8 + 1 = 9.

Step-by-step explanation:
A city has a population of 250,000 people. Suppose that each year the population grows by 6%. What will the population be after 12 years ?
Answer:
503,049
Step-by-step explanation:
250,000 × 1.06^12 is the formula.
You take the percentage which is 6% and you add 1 to it.
So, you get 1.06
Then you take the 1.06 and raise it to the number of years which is 12.
1.06^12
Then you multiply that number to the base number which is 250,000 and get 503,049.
Hope this helps!
Final answer:
To find the population after 12 years given a 6% annual growth, we apply the exponential growth formula. With an initial population of 250,000, the formula gives approximately 503,054 as the population after 12 years.
Explanation:
To calculate the population of a city after 12 years when it grows by an annual rate of 6%, we utilize the formula for exponential growth, P(t) = P0 * [tex](1 + r)^t[/tex], where P(t) is the population at time t, P0 is the initial population, r is the growth rate, and t is the number of years.
Given:
Initial population P0 = 250,000Growth rate r = 6% or 0.06Time t = 12 yearsThe population after 12 years can be calculated as follows:
P(12) = 250,000 * [tex](1 + 0.06)^{12}[/tex]
P(12) = 250,000 * [tex](1.06)^{12}[/tex]
P(12) ≈ 250,000 * 2.0122
P(12) ≈ 503,054
Therefore, the estimated population after 12 years is approximately 503,054.

John paid $34 for 2 books and 3 pencils. He paid $36 for 3 books and 2 pencils. How much was each?
Cost of each book is $ 8 and cost of each pencil is $ 6
Solution:
Let "a" be the cost of 1 book
Let "b" be the cost of 1 pencil
John paid $34 for 2 books and 3 pencils
Therefore,
2 books x cost of 1 book + 3 pencil x cost of 1 pencil = 34
[tex]2 \times a + 3 \times b = 34[/tex]
2a + 3b = 34 ----------- eqn 1
He paid $36 for 3 books and 2 pencils
3 books x cost of 1 book + 2 pencil x cost of 1 pencil = 36
[tex]3 \times a + 2 \times b = 36[/tex]
3a + 2b = 36 -------- eqn 2
Let us solve eqn 1 and eqn 2
Multiply eqn 1 by 2
4a + 6b = 68 ---------- eqn 3
Multiply eqn 2 by 3
9a + 6b = 108 --------- eqn 4
Subtract eqn 3 from eqn 4
9a + 6b = 108
4a + 6b = 68
( - ) -------------
5a = 40
a = 8
Substitute a = 8 in eqn 1
2(8) + 3b = 34
16 + 3b = 34
3b = 34 - 16
3b = 18
b = 6
Thus cost of each book is $ 8 and cost of each pencil is $ 6

12) The school that Danielle goes to is selling tickets to a choral performance. On the first day of
ticket sales the school sold 5 senior citizen tickets and 9 student tickets for a total of $144. The
school took in $192 on the second day by selling 14 senior citizen tickets and 6 student tickets.
What is the price each of one senior citizen ticket and one student ticket?
Answer:
Senior citizen tickets = $9
Student tickets = $11
Step-by-step explanation:
We begin by converting these into simultaneous linear equation;
Senior citizen tickets = a
Student tickets = b
5a + 9b = 144
14a + 6b = 192
5a = 144 - 9b
a = 144/5 - 9b/5
a = 28.8 - 1.8b
We now substitute this into the first equation
14(28.8 - 1.8b) + 6b = 192
403.2 - 25.2b +6b = 192
-19.2b = 192 - 403.2
b = -211.2/-19.2
b = 11
Put the value of b into either equation
5a + 9b = 144
5a + 9(11) = 144
5a +99 = 144
5a = 144-99
5a = 45
a = 9
