Answer:

Kurram is elder by 19 months

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.

What is linear inequality?

When a polynomial of degree 1 is compared to another algebraic expression of a degree less than or equal to 1, this is an example of a linear inequality, which is an inequality involving at least one linear algebraic expression. Different types of linear inequalities can be represented in a number of different ways.

The graph of the region shows a positive region which represents the value as a greater or increasing order.

The sign '>' represents the greater region.

a. If you can play the game for free, the expected value is zero since there is no cost and no prize for winning.

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)

= $12.50 - $2.63

= $9.87

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.

However, this does not mean that you will win every time you play, as the outcome of each individual game is still random.

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.

What is Mixture?

A mixture is generated when more than one chemical is mixed. A mixture can be created in a variety of ways, including using a liquid, solid, or gaseous medium.

First, let's add up the amount of the three ingredients to find the total volume of the mixture:

144 fl oz + 24 fl oz + 56 fl oz = 224 fl oz

Now, we can convert fluid ounces to quarts:

1 quart = 32 fluid ounces

So, we can divide the total volume in fluid ounces by 32 to find the total volume in quarts:

224 fl oz / 32 fl oz/quart = 7 quarts

Answer: 1.25 and 1.33

Step-by-step explanation:

question 3:

both sides of 24 became sides that measure 30.

24 times x = 30

therefore x, the scale factor, is 1.25

question 4:

3 increases to 4 and 15 increases to 20 (you have to rotate these shape before anything else to see the corresponding changes)

If radius of circle is tripled then area of circle will be increased by:9 times.

If the radius of a circle is tripled, then the new radius is three times the original radius, or R' = 3R, where R is the original radius and R' is the new radius. The area of a circle is given by the formula A = πR^2, where A is the area and R is the radius.

Substituting R' = 3R into the formula for the area of a circle, we get:

A' = πR'^2

= π(3R)^2

= 9πR^2

Therefore, the new area A' is 9 times the original area A. In other words, if the radius of a circle is tripled, the area of the circle will be increased by a factor of 9. This is because the area of a circle is proportional to the square of its radius.

The mean, also known as the average, is a central value that represents the typical value of a set of data.

To calculate the mean, you add up all the values in the data set and divide by the number of values. The mean provides a general sense of the distribution of the data and helps to identify any patterns or trends. In the stem-and-leaf plot, the mean can be calculated by adding up all the values and dividing by the number of throws. The mean in this case is 4.62 feet, which indicates that a typical throw of the ball results in 4.62 feet. This value can be used to gain a better understanding of the overall performance of the ball thrower and provide insight into how far the ball is typically thrown.

It is important to note that the mean is sensitive to outliers or extreme values, so it may not accurately reflect the typical value of the data in all cases. However, in this particular case, the mean provides a useful representation of the typical performance of the ball thrower.

Answer:d

Step-by-step explanation:

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.

The difference of the fractions 8/2 and 3/5 is given as follows:

17/5.

The difference operation for this problem is defined as follows:

8/2 - 3/5.

8 is divisible by 2, with a quotient of 4, hence the subtraction can be simplified as follows:

4 - 3/5.

With a common denominator of 5, we have that 4 x 5 = 20, hence:

20/5 - 3/5.

As the fractions now have a common denominator, we can subtract the numerators while keeping the denominator constant, thus the subtraction is given as follows:

(20 - 3)/5 = 17/5.

Any value of x that is less than or equal to -2 will make the inequality true.

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. Therefore, the number line that shows all of the values of x that make the inequality 3x - 1 <= -7 true is the one with all values less than or equal to -2 shaded.

The hybrid car will consume approximately 21.65 liters of gasoline to travel 132 km.To convert the hybrid car's fuel consumption rate from miles/gallon to kilometers/liter, we need to multiply by a conversion factor of 0.425 (1 mile = 1.609 kilometers, 1 gallon = 3.785 liters).

So the car's fuel consumption rate is 54.1 miles/gallon x 0.425 km/mile ÷ 3.785 liters/gallon = 6.09 km/liter.To find how many liters of gasoline the car will consume traveling 132 km, we can use the formula:

Gasoline consumed = distance traveled ÷ fuel consumption rate

Gasoline consumed = 132 km ÷ 6.09 km/liter = 21.65 liters (rounded to two decimal places).Therefore, the hybrid car will consume approximately 21.65 liters of gasoline to travel 132 km.
