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.

There are about 124.29 acres in this parcel woods

Step-by-step explanation:

The given is:

We 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

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

P = (0,4) Q = (2,0)

Step-by-step explanation:

Answer:

A. 2.3km

Step-by-step explanation:

Since 2cm = 1km

4.6cm = xkm

xkm = 4.6 x 1 / 2

= 2.3km

Answer:

I would believe that the answer is A. 2.3 km

Step-by-step explanation:

If 2cm=1km

then 4cm=2km

not to mention the km is 1/2 or the cm

so i would believe that .6cm would be .3km

therefore the answer must be 2.3km

Answer:

7.5

Step-by-step explanation:

The given exponential function is

[tex]f(x) = {2}^{x} + 3[/tex]

The average rate of change over a≤x≤b is given by;

[tex] \frac{f(b) - f(a)}{b - a} [/tex]

This implies that the average rate of change between the values 1 ≤ x ≤ 5 is

[tex] \frac{f(5) - f(1)}{5 - 1} [/tex]

We evaluate to get:

[tex]\frac{ {2}^{5} + 3 - {2}^{1} - 3}{4} = \frac{30}{4} = \frac{15}{2} = 7.5[/tex]

Answer:

This would equal 64

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.

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.

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:

The 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.

Answer:

25.12 feet

Step-by-step explanation:

To find the circumference of the round wading pool with an 8-foot diameter using 3.14 for pi, the formula C = πd is used, resulting in a circumference of 25.12 feet.

The question is asking to find the circumference of a round wading pool with a diameter of 8 feet using 3.14 for pi. The formula for the circumference of a circle is C = πd, where C represents the circumference, π (pi) is approximately 3.14, and d is the diameter of the circle. Given that the diameter (d) of the pool is 8 feet, we substitute the values into the formula to get:

C = 3.14 × 8 feet = 25.12 feet

Therefore, the circumference of the wading pool is 25.12 feet.

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
