The correct answer on the equation representing Kona's mother's age is option a) K² - 4.

Let M represent the Kona's mother's age = M = K² - 4.

Now substitute the value by taking Kona's age be 10.

= 10² - 4

= 100 - 4

=96.

Since the difference is Kona's age squared with subtracting 4.

The problem states that Kona's mother's age is the difference between Kona's age squared and four, We are given that the K represents Kona's age. Therefore, the expression for Kona's mother's age can be written as  K² - 4. This is because we substitute the K for the Kona's age and square it, then subtract four to find the mother's age. Hence the correct is option A. The difference code refers to the answer or result formed after subtracting the given equation or expression.

Answer:

To find out which rental car company is cheaper, you need to compare the cost for the same number of miles driven. Let's say you drive a total of "m" miles.

The cost for renting a car from Lou's Garage is 50 + 0.1m dollars.

The cost for renting a car from Jerry's Garage is 25 + 0.05m dollars.

To determine which option is cheaper, you need to compare these two expressions and find out which one is less. To do this, you can subtract the second expression from the first expression:

50 + 0.1m - (25 + 0.05m) = 25 + 0.05m

This equation shows that the cost of renting a car from Lou's Garage is 25 + 0.05m dollars more expensive than renting a car from Jerry's Garage for the same number of miles driven. Therefore, Jerry's Garage is the cheaper option.

Answer:

Based on these observations, the inequality represented by the graph is y > mx + b, where m is a positive number and b is a negative number.

Step-by-step explanation:

The graph represents a linear function. To find the inequality, we can find the equation of the line in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

From the graph, it can be seen that the slope of the line is positive, which means that as x increases, y also increases. Also, the y-intercept is negative, which means that the line crosses the y-axis at a negative value.

Based on these observations, the inequality represented by the graph is y > mx + b, where m is a positive number and b is a negative number.

Note that the exact values of m and b can be found by using two points on the line and solving for the slope and y-intercept using the formula for a line.

We can use the sine ratio to solve this problem and the value of x would be 8.604.

What are trigonometric ratios?

Trigonometric ratios are ratios of the side lengths of a right triangle with respect to its acute angles.

Sine (sin) ratio: The sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

In the given figure, we have given the hypotenuse of the triangle, and  an angle is given which is opposite to 35 degree, so we can use the sine ratio to find the value of x

sin35°= x/15

To solve for x, we can use the following steps:

Multiply both sides of the equation by 15 to isolate x:

sin 35° = x/15

15 * sin 35° = x

Use a calculator to approximate sin 35°:

sin 35° ≈ 0.5736

Substitute the approximation into the equation and solve for x:

x = 15 * 0.5736

x ≈ 8.604

Therefore, x is approximately equal to 8.604.

Hence, we can use the sine ratio to solve this problem and the value of x would be 8.604.

You did not make enough money to buy the television with a total earnings of $458

To write an expression for total earnings, we can use the given rates of pay and multiply them by the unit rates of the activites and then add them together.

So the expression for total earnings (E) is:

E = 10x + 8y + 20z

Where

Using the given parameters in the question, the total earnings (E) in the last 4 weeks is

E = ($10 x 9) + ($8 x 26) + ($20 x 8)

Evaluate

E = $90 + $208 + $160

E = $458

$458 is less than the cost of television ($540)

The unshaded area is 11.5 times bigger than the shaded area.

The area of the circle is given by:

A_circle = πr^2

where;

n this case, r = 10 cm, so:

A_circle = π(10 cm)^2 = 100π cm^2

The area of the semicircle is given by:

A_semicircle = (1/2)πr^2

where;

In this case, the diameter of the semicircle is 8 cm, so the radius is 4 cm:

A_semicircle = (1/2)π(4 cm)^2 = 8π cm^2

To find the area of the shaded region, we need to subtract the area of the semicircle from the area of the circle:

A_shaded = A_circle - A_semicircle

= 100π cm^2 - 8π cm^2

= 92π cm^2

The unshaded area is the area of the circle minus the area of the shaded region:

A_unshaded = A_circle - A_shaded

= 100π cm^2 - 92π cm^2

= 8π cm^2

So the unshaded area is 8π cm^2 and the shaded area is 92π cm^2.

There are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.

In this problem, we want to find the number of ways to seat 14 people in a circle such that every man is diametrically opposite a woman.

Since every man must be diametrically opposite a woman, we can pair each man with one woman. There are 5 men and 9 women, so there are 5 pairs. We need to find the number of ways to seat these 5 pairs of people in a circle.

To do this, we can first seat one pair in any position. Then, we can seat the second pair anywhere but opposite the first pair. This gives us 11 positions for the second pair. Continuing in this way, we see that there are 11 * 6 * 5 * 4 * 3 = 7920 ways to seat the 5 pairs of people in a circle.

Assuming 14 people, 5 men and 9 women, how many ways can they sit in a circle such that every man is diametrically opposite a woman?

Answer:

Step-by-step explanation:

Part A:

The actual length of the dining room is 120 inches and the percent error is -5%, which means that Rihana's measurement was too short. To find the length she measured, we need to add 5% to the actual length:

120 inches * (1 + (-5%)/100) = 120 inches * (1 - 0.05) = 120 inches * 0.95 = 114 inches

So Rihana measured the length of her dining room as 114 inches.

Part B:

To find the length that Rihana measured, we used the formula for calculating percent error:

measured length = actual length * (1 + (percent error)/100)

Since the percent error was negative (-5%), this means that Rihana's measurement was too short, so we subtracted the percent error from 100%. To do this, we added the negative percent error to 100%:

100% + (-5%) = 100% - 5% = 95%

So the measured length was 120 inches * 95% = 114 inches.

Aɳʂɯҽɾҽԃ Ⴆყ ɠσԃKEY ꦿ

The length of the dining room measured by Rihana with a -5%  percent error  is 114 inches.

What is a percent error?

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

A) Given the percent error as -5%.

The actual length = 120inches

Now error in measurement = 5% of 120 inches = 6 inches.

Since there is a negative sign in percent error, the measured value is 6 inches less than actual value.

Therefore the measured value = 120 - 6 = 114 inches.

B) We are given the actual length as 120 inches.

There is a -5% error in the measured value.

This means that the measured value is (5% of 120) inches less than actual value. It is identified as less because of the negative sign.

So the measured value is = 120 - 0.05*120 = 114 inches.

Therefore the length of the dining room measured by Rihana with a -5%  percent error is 114 inches.

b. To calculate the expected value when it costs $3 to play, we need to first find the probability of winning.

There are 8 possible outcomes on the spinner, and only one of them results in a win, so the probability of winning is 1/8. The probability of losing is 7/8.

The expected value is the sum of the product of each outcome and its probability. Let X be the amount won. Then:

E(X) = (1/8)($100) + (7/8)(-$3)

So the expected value when it costs $3 to play is $9.87. Since the expected value is positive, you can expect to make a profit in the long run.

What is Number line?

A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in primary mathematics. Every point on a number line is presumed to be a real number, and every real number is assumed to be a point.

To solve the inequality 3x - 1 <= -7, we can start by adding 1 to both sides to isolate the variable:

3x - 1 + 1 <= -7 + 1

Simplifying, we get:

3x <= -6

Next, we can divide both sides by 3 to solve for x:

3x/3 <= -6/3

Simplifying, we get:

x <= -2

This tells us that any value of x that is less than or equal to -2 will make the inequality true. We can represent this on a number line by shading all values less than or equal to -2

The circle at -2 indicates that -2 is included in the solution set, and the arrow pointing to the left indicates that all values less than -2 are also included in the solution set.
