The total capacity of the big school bus is 140 children.

To find out how many children can fit into the big school bus, let's work through the given information step by step.

When the bus left Area A, it was 2/7 full. This means that 2/7 of the bus's capacity was occupied by children. Let's represent the total capacity of the bus as 'x'. Therefore, 2/7 of 'x' corresponds to the number of children on the bus when it left Area A.

After the bus arrived at Area B, 9 children alighted, which means the number of children decreased by 9. We are then told that there were 31 children remaining on the bus. So, the number of children on the bus before any alighted was 31 + 9 = 40.

Since 2/7 of the bus's capacity was occupied by children when it left Area A, we can set up the following equation:

(2/7) * x = 40

To solve for 'x', we can multiply both sides of the equation by (7/2):

x = 40 * (7/2)

x = 140

Therefore, the total capacity of the big school bus is 140 children.

The feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

To determine whether the feasible set for each system of constraints is convex, we need to analyze the constraints individually and examine their intersection.

a) (x1)² + (x2)² > 9

This constraint represents points outside the circle with a radius of √9 = 3. The feasible set includes all points outside this circle.

b) x1 + x2 ≤ 10

This constraint represents points that lie on or below the line x1 + x2 = 10. The feasible set includes all points on or below this line.

c) x1, x2 > 0

This constraint represents points in the positive quadrant, where both x1 and x2 are greater than zero.

Now, let's analyze the intersection of these constraints:

Considering the first two constraints (a and b), we can see that the feasible set consists of all points outside the circle (constraint a) and below or on the line x1 + x2 = 10 (constraint b).

To determine whether the feasible set is convex, we need to check if any two points within the set create a line segment that lies entirely within the set.

If we consider the points (5, 5) and (3, 7), both points satisfy the individual constraints (a) and (b). However, the line segment connecting these two points, which is the line segment between (5, 5) and (3, 7), exits the feasible set since it passes through the circle (constraint a) and above the line x1 + x2 = 10 (constraint b).

Therefore, the feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

The exchange rate is 1 USD = 0.992714 EURO

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

We need to convert between units in order to ensure accuracy and prevent measurement misinterpretation. For example, we do not measure a pencil's length in kilometres. In this situation, one must convert from kilometres (km) to centimetres (cm) (cm).

Given:

1 US dollar = _________ euro.

As, the exchange rate between US dollar to Euros

1 USD = 0.992714 EURO

1 USD = 1 EURO

y = 8x - 5

Step-by-step explanation:

Given:

To find:

How to find:

The slope is always known as "constant of variation" or "rate of change", but it's basically the increase of both y and x axes in simple terms. The decrease or increase in two points together and then found with the formula of rise/run (increase and decrease) (horizontal line/vertical line).

The y-intercept is always on the y-axis and is the beginning of what is learned in pre-algebra as a "story" which helps students practice finding the slope which again, is the change with "per" or "each".

Make sure to use the formula:

y = mx + b

Now we insert.

y = 8x <---------- slope

y = 8x - 5 <------ y-intercept and completed slope-intercept equation.

The reason it has a negative is because it started out as a negative y-intercept and is increasing by 8 through ordered pairs.

Answer:

y = 8x - 5

Step-by-step explanation:

because if its has a slope of 8 then m is 8

if the y intercept is -5 the b is -5

y = mx + b

y = 8x -5

The equation is y = (5/3)x. Then the cost of the 12 yards of fabric will be $20. Then the correct option is B.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

\(\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)\)

The two points are (3, 5) and (6, 10).

Let 'x' be the number of yards of fabric and 'y' be the cost in dollars. Then the equation is given as,

(y - 5) = [(10 - 5) / (6 - 3)](x - 3)

y - 5= (5/3)x - 5

y = (5/3)x

The cost of the 12 yards of fabric is given as,

y = (5/3) × 12

y = 5 × 4

y = $20

The equation is y = (5/3)x. Then the cost of the 12 yards of fabric will be $20. Then the correct option is B.

The correct answer is b) unchanged. Cutting a chocolate bar in half does not affect its density.

When a chocolate bar is cut in half, its density remains unchanged. Density is a physical property of a substance that is determined by its mass per unit volume. When the chocolate bar is cut in half, the mass is also divided into two equal parts, resulting in a reduction of the volume by half as well. Since both the numerator and denominator in the density formula change proportionally, the density remains the same.

For example, if the density of a chocolate bar is 1 gram per cubic centimeter, cutting it in half would result in two smaller bars, each with half the volume and half the mass. The density of each of the new bars would still be 1 gram per cubic centimeter, even though they are smaller in size.

Therefore, the correct answer is b) unchanged. Cutting a chocolate bar in half does not affect its density.

The sum of the series is 1/2. The sequence An= (6n) / (4n+3) converges to 3/2.

The first series can be written as:

∑n=1 to [infinity] (3^n-1) / (8^n) = ∑n=1 to [infinity] [(3/8)^n - (1/8)^n]

We can simplify the series as:

∑n=1 to [infinity] (3^n-1) / (8^n) = [(3/8)^1 - (1/8)^1] + [(3/8)^2 - (1/8)^2] + [(3/8)^3 - (1/8)^3] + ...

= (3/8 - 1/8) + (9/64 - 1/64) + (27/512 - 1/512) + ...

= 2/8 + 8/64 + 26/512 + ...

=(1/4) + (1/8) + (1/32) + ...

This is a geometric series with first term a = 1/4 and common ratio r = 1/2. Since the absolute value of r is less than 1, the series converges. The sum of the series is:

sum = a / (1 - r) = (1/4) / (1 - 1/2) = (1/4) / (1/2) = 1/2

For the second sequence:

The sequence is given by An = (6n) / (4n+3).

Taking the limit as n approaches infinity, we have:

lim n→∞ An = lim n→∞ (6n) / (4n+3) = lim n→∞ (6/4 + 9/(4n+3))

As n approaches infinity, the second term goes to zero, and we are left with:

James has a total of 21.9 kilograms of sand in his sandbox after adding the sand from the beach. To find the total weight of sand in James' sandbox, we need to convert the given weights from grams to kilograms.

James initially has 14,500 g of sand. To convert this to kilograms, we divide by 1000:

14,500 g ÷ 1000 = 14.5 kg

Next, James brings home an additional 7,400 g of sand from the beach. To convert this to kilograms, we divide by 1000:

7,400 g ÷ 1000 = 7.4 kg

To find the total weight of sand in James' sandbox, we add the initial amount of sand to the amount he brought from the beach:

14.5 kg + 7.4 kg = 21.9 kg

Step-by-step explanation:

First let's get rid of the starting fee of $2

\(16.28 - 2 = 14.28\)

Then divide 14.28 by 0.12 ($14.28 ÷ $0.12)

\(14.28\) ÷ \(0.12 = 119\)

Thus Dante rode the scooter for 119 minutes

The number of minutes that Dante rode the scooter will be 119 minutes.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

For a ride on a rental scooter, Dante paid a $2 fee to start the scooter plus 12 cents per minute of the ride.

Let x be the number of minutes and y be the total amount.

y = 0.12x + 2

The total bill for Dante's ride was $16.28. Then the number of minutes that Dante rode the scooter will be

16.28 = 0.12x + 2

14.28 = 0.12x

It takes approximately 3 hours for an average adult to metabolize four 12-ounce beers.

The alcohol has a half-life of about 3 hours. This means that for every three hours that pass, the amount of alcohol in your body decreases by half. Alcohol is metabolized primarily in the liver.

Here, enzymes break down the ethanol molecule and turn it into a less toxic chemical called Acetaldehyde. Acetaldehyde is then further broken down by the enzyme aldehyde dehydrogenase into Acetic acid. Acetic acid is then further broken down into water and Carbon dioxide and eventually eliminated from the body.

So, for an average adult, it takes approximately 3 hours to metabolize four 12-ounce beers. The rate of metabolism can be affected by a number of factors such as age, gender, body composition, and the rate at which the alcohol was consumed.

Additionally, factors such as weight, body fat percentage, and the amount of food in the stomach can also influence the rate of alcohol metabolism. It is important to note that even after the alcohol is metabolized, it can still remain in the system and affect cognitive and motor skills.

Therefore, it is important to give the body enough time to metabolize the alcohol before attempting to drive or operate any type of machinery.

MN = 25

Step-by-step explanation:

If LN=45, then the addition of both quantities will be 45.

LN = 3x + 2 + x + 19

3x + 2 + x + 19 = 45

4x + 21 = 45

4x = 45 - 21 = 24

x = 6

Now that we found the value of "x", we can find the lenght of MN

MN = x + 19

MN = 6 + 19

MN = 25

Hope it was helpful ;)

Answer: MN = 25

Step-by-step explanation:

Since the length is already given we just add the equations equal to it.

45 =  3x + 2 + x + 19  Combine like terms

45 = 4x + 21               Subtract 21 from both sides

24 = 4x                       Divide by 4

x = 6

Now we plug x into the equation needed.
