Answer:

a) 5x/16

b) x = 32

Step-by-step explanation:

a) x/8 + 3x/16 can be simplified by getting a common denominator. x/8 can be changed like this:

x/8 × 2/2 is 2x/16

now we have:

2x/16 + 3x/16

= 5x/16

b) solve x/8+3x/16=10

change the left side of the equation as in part a.

5x/16 = 10

multiply both sides of the equation by 16

5x = 160

divide by 5

x = 32

we can replace the second occurrence of x = -2 with x = 1:

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range.

For the table to be a function, each x-value must correspond to a unique y-value. To determine the missing x-value, we need to find if there are any repeated x-values with different y-values.

The x-value 3 is paired with y-values -3 and -1, which means that the table is not a function. Therefore, we need to replace one of the x-values that appears twice with a different value.

Since x = 0 is already paired with y = 5, we cannot use 0 as the replacement. The only other x-value that appears more than once is x = -2. Therefore, we can replace one of the occurrences of x = -2 with a different value.

For example, we can replace the second occurrence of x = -2 with x = 1:

x    y

3   -3

1    4

-2  -1

-2  -2

0    5

Now each x-value corresponds to a unique y-value, so the table represents a function.

Answer: option (a) and option (e).

Step-by-step explanation:

Answer:

(a) and (e) are correct

Step-by-step explanation:

(a) x² + (y - 3)² = 6²

(b) x² + (y - 5)² = (√6)²

(c) (x - 4)² + y² = 6²

(d) (x + 6)² + y² = 12²

(e) x² + (y + 8)² = 6²

The general equation of a circle is:

(x - a)² + (y - b)² = r², where (a, b) represents the x-y coordinates of the centre, and r represents the radius.

Hence, by process of elimination, the options that have a diameter of 12 units and therefore, a radius of 6 units, are (a), (c), and (e).

Therefore, the correct choices are (a), and (e), as (c) has a circle centre of (4,0) and does not lie on the y-axis.

Therefore, the graph of the given set is: closed circles on 1 and 4 with a line segment between.

A common form for an algebraic expression is one of the following: addition, subtraction, multiplication, or division. Simplify the values to determine the result.

The expression (x I x ≤ 1) U (x I x ≥ 24) represents the set of all values of x that are less than or equal to 1 or greater than or equal to 24.

1) probability that Ed will answer all 6 questions correctly is approximately 0.00024.

2) probability that Ed will answer exactly 2 questions correctly is approximately 0.29663.

3) probability that Ed will answer at least 2 questions correctly is approximately 0.46606.

What is Probability?

Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.

1) Probability of answering 6 questions correctly:

Since there are 4 choices for each question, the probability of guessing the correct answer for a single question is 1/4.

P(6 correct) = [tex](1/4)^{6}[/tex] = 0.00024414 ≈ 0.00024

So the probability that Ed will answer all 6 questions correctly is approximately 0.00024.

2) Probability of answering exactly 2 questions correctly:

The probability of guessing exactly 2 questions correctly can be calculated using the binomial probability formula:

P(exactly 2 correct) = (6 choose 2) * (1/4)² * [tex](3/4)^{4}[/tex]

P(exactly 2 correct) ≈ 0.29663

So the probability that Ed will answer exactly 2 questions correctly is approximately 0.29663.

3) Probability of answering at least 2 questions correctly:

P(at least 2 correct) = P(2 correct) + P(3 correct) + P(4 correct) + P(5 correct) + P(6 correct)

P(k correct) = (6 choose k) * [tex](1/4)^{k}[/tex] * [tex](3/4)^{(6-k)}[/tex]

where k can be 3, 4, or 5.

P(at least 2 correct) ≈ 0.46606

So the probability that Ed will answer at least 2 questions correctly is approximately 0.46606.

Step-by-step explanation:

The reason why it is possible to draw two different rectangles that have an area of 30 square inches is that there are multiple pairs of whole numbers that multiply to 30. For example, a rectangle with dimensions 5 inches by 6 inches has an area of 30 square inches, and so does a rectangle with dimensions 2 inches by 15 inches.

However, the number 7 is a prime number, which means it can only be divided evenly by 1 and itself. Therefore, the only way to get an area of 7 square inches for a rectangle is by multiplying 1 and 7, which means the dimensions of the rectangle would be 1 inch by 7 inches. Since there are no other pairs of whole numbers that multiply to 7, it is not possible to draw two different rectangles with an area of 7 square inches.

First, we can use the given information to find the ratio between green and yellow:

6 yellow = 5 green

=> green/yellow = 6/5

Next, we can use the given information to find the ratio between purple and green:

4 green = 3 purple

=> purple/green = 4/3

Finally, we can use the given information to find the ratio between red and purple:

5 purple = 2 red

=> red/purple = 5/2

To find the ratio between yellow and red, we can combine these ratios and simplify:

green/yellow = 6/5

=> yellow/green = 5/6

purple/green = 4/3

=> green/purple = 3/4

red/purple = 5/2

=> purple/red = 2/5

yellow/green * green/purple * purple/red = yellow/red

(5/6) * (3/4) * (2/5) = 1/2

Answer:

Step-by-step explanation:

To find out how many bunches of each flower the shop should order, we need to calculate the percentage of customers who preferred each flower, and then use that percentage to estimate the number of bunches needed for each flower.

First, we need to calculate the total number of customers who were surveyed:

Total customers surveyed = 8 + 4 + 8 + 20 = 40

Next, we can calculate the percentage of customers who preferred each flower:

Percentage of customers who preferred daisy = (8/40) x 100% = 20%

Percentage of customers who preferred gardenia = (4/40) x 100% = 10%

Percentage of customers who preferred mum = (8/40) x 100% = 20%

Percentage of customers who preferred rose = (20/40) x 100% = 50%

Now, we can use these percentages to estimate how many bunches of each flower to order.

Let's assume that each bunch contains 10 flowers (this is just an example, the actual number may vary):

Number of bunches of daisy to order = 20% of 50 bunches = 10 bunches

Number of bunches of gardenia to order = 10% of 50 bunches = 5 bunches

Number of bunches of mum to order = 20% of 50 bunches = 10 bunches

Number of bunches of rose to order = 50% of 50 bunches = 25 bunches

So, the shop should order 10 bunches of daisy, 5 bunches of gardenia, 10 bunches of mum, and 25 bunches of rose to meet the expected demand on Sunday.

The solutions to the equation -b² + 2b = 0 are b = 0 and b = 2.

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, a left-hand side (LHS) and a right-hand side (RHS), which are connected by an equals sign (=). The expressions on each side of the equals sign can be made up of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. An equation can be solved to find the value of the variable(s) that makes both sides of the equation equal.

To find the solution of -b²+ 2b = 0, we can use algebraic manipulation as follows:

-b² + 2b = 0

Factor out -b:

-b(b - 2) = 0

From this equation, we see that either -b = 0 or b - 2 = 0:

-b = 0 or b - 2 = 0

Solving for b in each case, we get:

-b = 0 --> b = 0

b - 2 = 0 --> b = 2

Therefore, the solutions to the equation -b² + 2b = 0 are b = 0 and b = 2.

a) The angular velocity of the wheel is approximately 1.0667 radians per second. b) The wheel will spin at approximately 10.16 revolutions per minute.

Angular velocity is a measure of how quickly an object rotates or revolves around a fixed point, such as an axis or a center of rotation. It is a vector quantity that describes the rate of change of an object's angular position with respect to time, and is usually expressed in units of radians per second (rad/s) or degrees per second (deg/s).

a) To find the angular velocity of the wheel, we can use the formula:

angular velocity = linear velocity / radius

In this case, the linear velocity of the hamster is 16 centimeters per second, and the radius of the wheel is 15 centimeters. So, we have:

angular velocity = 16 / 15

angular velocity = 1.0667 radians per second

Therefore, the angular velocity of the wheel is approximately 1.0667 radians per second.

b) To find the speed of the wheel in revolutions per minute, we need to convert the angular velocity from radians per second to revolutions per minute. There are 2π radians in one revolution, and 60 seconds in one minute. So, we can use the following formula:

angular velocity (in revolutions per minute) = angular velocity (in radians per second) * 60 / 2π

Plugging in the angular velocity we found in part (a), we get:

angular velocity (in revolutions per minute) = 1.0667 * 60 / 2π

angular velocity (in revolutions per minute) ≈ 10.16 revolutions per minute

Therefore, the wheel will spin at approximately 10.16 revolutions per minute.

The smaller number is 6 .

The larger number is 22

Let's let x be the smaller number and y be the larger number.

From the problem, we know that one number is eight less than five times the other, so we can write:

y = 5x - 8

We also know that the sum of the two numbers is 28, so we can write:

x + y = 28

Now we have two equations in two variables. We can solve for one of the variables in terms of the other, and substitute that expression into the other equation to eliminate one variable.

Let's solve the first equation for x

x = (y + 8)/5

Now we can substitute this expression for x into the second equation:

(y + 8)/5 + y = 28

Multiplying both sides by 5 to eliminate the fraction, we get:

y + 8 + 5y = 140

Combining like terms, we get:

6y + 8 = 140

Subtracting 8 from both sides, we get:

6y = 132

Dividing both sides by 6, we get:

y = 22

Now we can use the equation y = 5x - 8 to solve for x:

22 = 5x - 8

Adding 8 to both sides, we get:

30 = 5x

Dividing both sides by 5, we get:

x = 6

Therefore, the smaller number is 6 and the larger number is 22.

Answer:  the simplified form of sec(Q) is sqrt(24/7).

Step-by-step explanation: The equation secant of angle Q is equal to two multiplied by the square root of six and divided by nine.

In order to reduce the complexity of the given mathematical expression, it is possible to employ the fundamental definition of secant, which states that:

The trigonometric identity denoted as sec(Q) equals the reciprocal of the cosine function evaluated at the angle Q. More precisely, sec(Q) = 1 / cos(Q).

The value of cos(Q) may be determined through the utilization of the Pythagorean identity.

The present mathematical equation demonstrates a fundamental identity in trigonometry, wherein the squares of the sine and cosine functions are summed to equal one. Written symbolically, the equation can be expressed as sin^2(Q) + cos^2(Q) = 1.

Given the condition that sec(Q) is positive, it is ascertainable that Q is situated within the first or fourth quadrant, wherein the cosine of Q is likewise positive. Consequently, the derivation for the solution of the cosine of the angle Q can be expressed as follows:

The trigonometric identity expressed as cos(Q) = sqrt(1 - sin^2(Q)) is a fundamental result in the field of mathematics. This particular equation provides a relationship between the cosine and sine functions of angle Q. Specifically, it states that the cosine of an angle Q is equal to the square root of one minus the sine squared of the same angle Q. The use of such identities is common in mathematical analysis and applied sciences, where it allows for efficient manipulation of trigonometric functions and the mathematical modeling of a variety of physical phenomena.

The following mathematical expression can be written in an academic style: Cosine of angle Q can be expressed as the square root of one minus the square of nine divided by twice the square root of six, i.e., cos(Q) = √(1 - (9/2√6)^2), while substituting the value of sine of angle Q as being equal to nine divided by twice the square root of six (i.e., sin(Q) = 9/2√6).

The mathematical expression cos(Q) = sqrt(1 - (81/24)) may be represented in a more academic manner. Specifically, it may be articulated as follows: the cosine of angle Q is equivalent to the square root of one subtracted by the quotient of 81 and 24. This revision lends itself to a more formal and precise mode of communication, which is characteristic of academic writing.

The mathematical expression cos(Q) = √(7/24) can be represented in a formal and academic manner.

The value of secant of angle Q can now be determined as:

The trigonometric function defining the secant of an angle Q is expressed as sec(Q) = 1/cos(Q).

The trigonometric function, sec(Q), can be expressed as the reciprocal of the square root of 7/24.

The mathematical statement, sec(Q) = sqrt(24/7), can be expressed in a formal and academic manner as follows. The reciprocal of the cosine function of the angle Q is equivalent to the square root of the fraction 24 over 7.

The daily rental rate for a compact car is $ [tex]56,[/tex] and the optional insurance costs $10 per day. Therefore, the total daily cost of renting a compact car with insurance is:

[tex]56 + 10 = 66[/tex]

To determine the total cost of renting the compact car for 8 days, we simply multiply the daily cost by the number of days:

[tex]66 \times 8 = $528[/tex]

Next, we need to determine the cost of gasoline if Nate returns the car without a full tank. The gasoline charge is $ [tex]3.50[/tex] per gallon, but we don't know how many gallons Nate will need to fill up the tank.

If we assume that a compact car has a gas tank capacity of around 12 gallons, and that Nate will need to refill the tank to its full capacity, then the gasoline charge would be:

$[tex]3.50 \times 12 = $42[/tex]

Finally, we can calculate the total cost of the rental, including the optional insurance and the gasoline charge if Nate returns the car without a full tank:

$[tex]528 + $42 = $570[/tex]

Therefore, the total cost of the car rental for Nate if he rents a compact car with the optional insurance and fills up the gas tank before returning the car would be $[tex]570[/tex].
