The area of the various shapes are:

1) Area of a circle (with radius 8in) 200.96

2) Area of Rectangle (45 *14) = 630in

3) Area of rectangle (24 *9) = 216in

4) Area of pentagon with side 10in = 172.05

5) Area of circle with diameter 20in = 314

6) Area of rectangle 5 x 8 = 40ft.

Lets take the circles first where the radius is 8in.

1) The area of a circle is

A = πr²

A =  π x r²

A = 3.14 x 8²

A = 200.96

2) Area of circle with diameter of 20 inches

Where diameter is 20inches, radius is 10inches

So
A =  3.14 x 10²

A = 3.14 x 100

A =  314

Now to the rectangles

1) Area of rectangle is L x B

Where L = Length

B = Breath

So,

A = 45 * 14 = 630in

2) A = 24 x 9 = 216 in

3) A = 5 x 8 = 40 inches

Next the pentagon.

Formula for Area of Pentagon is

Area = (1/4) * √(5 * (5 + 2 * √(5))) * s²

Where s = Side.

Since s = 10in

Area = (1/4) * √(5 * (5 + 2 * √(5))) * (10)²

A = 172.05

When the population of a protozoa develops with a constant relative growth rate of 0.6685 per member per day, and there are two members on the day zero, the population after will consist of 7 at the end of seven days period.

The total population of the protozoa at the end of the seven days can be computed using the calculations given below,

Total Population = Growth Rate x Number of Days + Day zero Population

Total Population = (0.6685 x 7) + 2

Total Population = 6.667, or ~ 7.

If the only marks that remain are at 1 inch and 2 inches, 9 inches and one mark, the missing mark corresponds to the number 6.

This is a classic problem in recreational mathematics, also known as the "burnt ruler problem". To solve it, we need to think creatively and use rational expressions and equations.

First, we note that the distance between the two marks is 9-2=7 inches. We can imagine the ruler as a number line from 0 to 9, where the two marks correspond to the numbers 1 and 2. We want to find the other mark, which corresponds to some number x between 2 and 9.

Next, we observe that we can use the ruler to construct line segments of length 1, 2, 3, 4, 5, 6, 7, 8, and 9 by adding or subtracting these lengths using the two marks as reference points. For example, we can construct a line segment of length 3 by starting at the mark at 2, moving 1 inch to the right, and then moving 2 more inches to the right.

Now, we notice that any line segment of length n can be expressed as a difference of two line segments of smaller lengths. For example, a line segment of length 7 can be expressed as the difference between a line segment of length 2 and a line segment of length 5. More generally, we can write:

n = a - b

where a and b are integers between 1 and n-1.

Using this observation, we can try to find a way to express the length of the missing segment x as a difference of two integers between 1 and 7. We can start by listing all possible values of a and b:

a=2, b=1: 2-1=1

a=3, b=1: 3-1=2

a=4, b=1: 4-1=3

a=5, b=1: 5-1=4

a=6, b=1: 6-1=5

a=7, b=1: 7-1=6

a=3, b=2: 3-2=1

a=4, b=2: 4-2=2

a=5, b=2: 5-2=3

a=6, b=2: 6-2=4

a=4, b=3: 4-3=1

a=5, b=3: 5-3=2

a=6, b=3: 6-3=3

a=5, b=4: 5-4=1

a=6, b=4: 6-4=2

a=6, b=5: 6-5=1

We notice that the only values of a and b that work are 6 and 1, respectively, since 6-1=5, which is the length of the line segment between the two marks that was not given.

The length of the rectangle is 23 km and the width of the rectangle is 15 km.

A rectangle is 8 km longer than it is wide.

Its area is 345 sq-km.

Let the width of the rectangle is x.

The length is 8 km longer than the width.

So the width of the rectangle is x + 8 km.

The formula of the area of rectangle is:

A = length × width

We know A = 345 sq-km.

Now putting the value

x × (x + 8) = 345

Now simplifying

x^2 + 8x = 345

Subtract 345 on both side, we get

x^2 + 8x - 345 = 0

Now factor the equation

x^2 + (23 - 15)x - 345 = 0

x^2 + 23x - 15x - 345 = 0

x(x + 23) - 15(x + 23) = 0

(x - 15)(x + 23) = 0

Now equation the factor equal to zero.

x - 15 = 0           or             x + 23 = 0

x = 15                or              x = -23

Since the dimension of the rectangle can't be negative. So

The width of the rectangle is 15 km.

Now we determine the value of length

x + 8 = 15 + 8 = 23

The set of parameters that would give you the highest position within the class with a score of x = 75 is option (C) μ = 60 and σ = 5 is the correct answer.

In this question,

A z-score tells us how many standard deviations away a value is from the mean. A positive z-score indicates the raw score is higher than the mean average. A negative z-score reveals the raw score is below the mean average.

According to the Percentile to z-score calculator, the z-score that corresponds to the 90th percentile is 1.2816. Thus, any student who receives a z-score greater than 1.2816 would be considered a “good” z-score.

The z-score can be calculated as

z-score = \(\frac{x-\mu}{\sigma}\)

On substituting the above options of μ and σ with the score of x = 75,

a) μ = 70 and σ = 5,

z-score = \(\frac{75-70}{5}\)

⇒ \(\frac{5}{5}\) = 1

b) μ = 70 and σ = 10,

z-score = \(\frac{75-70}{10}\)

⇒ \(\frac{5}{10}\) = 0.5

c) μ = 60 and σ = 5,

z-score = \(\frac{75-60}{5}\)

⇒ \(\frac{15}{5}\) = 3

d) μ = 60 and σ = 10

z-score = \(\frac{75-60}{10}\)

⇒ \(\frac{15}{10}\) = 1.5

Thus the z-score 3, is the higher value. 99% have a z-score between -3 and 3. Therefore, the set of parameters that would give you the highest position within the class with a score of x = 75 is option (C) μ = 60 and σ = 5 is the correct answer.

Answer:

the system of equations has infinite solution

Step-by-step explanation:

Reese states that the system of equations has no solution because the slopes are the same. Describe Reese’s error. ( y=−3x−1 ), ( 3x+y=−1 )

Solution:

The equation of a straight line graph is given by:

y = mx + b, where m is the slope of the line and b is the y intercept.

A system of linear equations has no solution when the graphs are parallel, that is they have the same slope and different y intercept.

A system of linear equations has infinite solutions when the graphs are the exact same line, that is they have the equal slope and equal y intercept.

The first equation: y = -3x - 1 has a slope of -3 and y intercept of -1.

The second equation: 3x + y = - 1; i.e. y = -3x - 1  has a slope of -3 and y intercept of -1.

Since both equations have equal slope and equal y intercept, hence both equations are infinite solutions.

Therefore the statement that the system of equations has no solution is wrong.

Where the above conditions are given,  the correct option is: Plan 1 is a better deal for more than 5 cards purchased.

To determine   which pricing plan is a better deal,we need to compare the total cost for a certain number of game cards purchased.

Let's calculate the   total cost for different numbers  of game cards.

For Plan 1  -

- Admission fee  - $5 (fixed)

- Cost per game card  - $1

For Plan 2  -

- Admission fee  - $2.50 (fixed)

- Cost per game card  - $1.50

Now, let's compare the total cost for different numbers of game cards  -

1. If you purchase 1 game card  -

  - Plan 1  - $5 (admission fee) + $1 (cost per game card) = $6

  - Plan 2  - $2.50 (admission fee) + $1.50 (cost per game card) = $4

2. If you purchase 5 game cards  -

  - Plan 1  - $5 (admission fee) + $5 (cost for 5 game cards) = $10

  - Plan 2  - $2.50 (admission fee) + $7.50 (cost for 5 game cards) = $10

3. If you purchase 8 game cards  -

  - Plan 1  - $5 (admission fee) + $8 (cost for 8 game cards) = $13

  - Plan 2  - $2.50 (admission fee) + $12 (cost for 8 game cards) = $14.50

Based on these calculations, we can conclude that  -

- Plan 1 is a better deal for more than 5 cards purchased.

- Plan 2 is a better deal for more than 8 cards purchased.

Therefore, the correct option is  - Plan 1 is a better deal for more than 5 cards purchased.

The distance along the unit circle between any two successive 8th roots of 1 is c) π/4.

To find the distance along the unit circle between any two successive 8th roots of 1, we can consider the concept of angular displacement.

Each 8th root of 1 represents a point on the unit circle that is evenly spaced by an angle of 2π/8 = π/4 radians.

Starting from the point corresponding to 1 on the unit circle, we can move π/4 radians to reach the first 8th root of 1. Moving π/4 radians further will bring us to the second 8th root of 1, and so on.

Since we are moving by π/4 radians for each successive 8th root of 1, the distance between any two successive 8th roots of 1 is π/4 radians.

Therefore, the correct answer is option c. π/4.
