If d is distance measured in km and t is time measured in hours, then d = 69t tells you that train A is moving at a rate of 69 km/h.

Why? If t = 1, then d is the distance it moves in 1 hour, and that's precisely the unit rate. It's the rate at which the distance changes when 1 unit of time passes.

For train B, use the info in the given table. In 1 hour (between hours 4 and 5), the train covers a distance of 375 km - 300 km = 75 km. So it's moving at a rate of 75 km/h.

It should be clear which train is faster.

\(d(A) = 69t\)

\(d(B) = 75t\)

The unit rate is the coefficient of t which is the slope of the line because the trains distance traveled equation are linear.

Thus :

Train A's unit rate is 69 km per hour.

And

Train B's unit rate is 75 km per hour.

Answer:

13.27 cm

Step-by-step explanation:

I am using (xy) to mean the length of the side xy

7^2 + (xy)^2 = 15^2

49 + (xy)^2 = 225

(xy)^2 = 225-49

(xy)^2 = 176

Side (xy) = sqrt(176) = 13.2664991614 = 13.27 cm

The difference in volume between the two boxes would be = 156in³

To calculate the difference in volume between the boxes is the find the individual volume of the boxes using the formula ;

Volume = length×width×height.

For box 1 = length = 12in, width = 7¾in, height= 2in

Vol = 12×7¾×2 = 186in³

For box 2; length = 3⅔in, width = 3½in, height= 2⅓in

Mary Lou Mason's total taxes on her purchase would be $1.37.

Taxes are mandatory payments to the government that are used to fund public services such as infrastructure, education, and health care. Taxes can be direct, such as income taxes, or indirect, such as sales taxes.

Mary Lou Mason's total purchase was $19.14.

To calculate the total taxes for her purchase, we can use the following formula:

Tax = (State Sales Tax %) x (Total Purchase) + (County Tax %) x (Total Purchase)

Therefore, the total taxes for Mary Lou Mason's purchase would be:

Tax = (6.5%) x ($19.14) + (1.5%) x ($19.14)

Tax = (0.065 x 19.14) + (0.015 x 19.14)

Tax = 1.24 + 0.13

The width of the field is 230 feet and the length is 310 feet.

Let's denote the width of the field as "x" feet.

The length of the field is 80 feet longer than the width, so it can be represented as "x + 80" feet.

To find the total amount of fencing material needed, we sum up the lengths of all four sides of the rectangular field:

2(length) + 2(width) = perimeter

Substituting the given values:

2(x + 80) + 2(x) = 1080

2x + 160 + 2x = 1080

4x + 160 = 1080

4x = 920

x = 920/4

x = 230

Therefore, the width of the field is 230 feet.

Now we can find the length by adding 80 feet to the width:

Length = Width + 80 = 230 + 80 = 310 feet.

So, the width of the field is 230 feet and the length is 310 feet.

The correct answer is that the data set {3, 7, 4} is represented in the given histogram.(option-a)

The given histogram represents the number of children in each age group who need to travel to school. Since the histogram has only three bars, we can conclude that there are only three age groups.

The first bar represents children aged 5-10, of which there are 3. The second bar represents children aged 11-13, of which there are 7. The third bar represents children aged 14-18, of which there are 4.

Therefore, the data set that is represented in the histogram is:

Measurement of weight 6 is in ounces and the measurement of weight 170 is in grams.

What is measurement?

An object or event's attributes are quantified through measurement so that they can be compared to those of other things or events. Measurement, then, is the process of establishing how big or small a physical quantity is in relation to a fundamental reference quantity of the same kind.

Given:

Elena has a pet parakeet that weighs 6 when measured in one unit and

170 when measured in a different unit.

We have to find the correct units from grams and ounces for these.

We know that, 1 ounce is greater than 1 gram.

1 ounce = 28.3495 grams

Multiply both sides by 6.

6 ounces = 170.097 grams

Approximate the values to the nearest whole number.

6 ounces = 170 grams

Therefore, 6 ounces = 170 grams.

Option B is a correct representation of the given number line,  -3.8 < 1.5, and is located to the left of 1.5.

A number line is a visual depiction of numbers on a straight line drawn either horizontally or vertically. It is simple for humans to compare numbers and carry out simple arithmetic operations on them when they are written down on a number line. A number line is thought to begin at zero (0). Left of zero, there are only negative numbers, and right of zero, there are only positive numbers.

Given a number line and two points marked on it,

-3.8 and 1.5

we find from the number line that -3.8 lie left to 1.5,

and the negative numbers are always less than the positive numbers,

so -3.8 is less than 1.5,

-3.8 < 1.5, and lie left to 1.5.

What is alphanumeric series?

An alphanumeric series is a sequence of letters and/or numbers that follows a certain pattern or rule. For example, "A, B, C, D, E..." is an example of an alphabetical series, and "1, 3, 5, 7, 9..." is an example of a numerical series. An alphanumeric series may combine both letters and numbers, such as "A1, B2, C3, D4, E5...". The pattern or rule followed by an alphanumeric series may be based on numerical or alphabetical order.

The given series V, Q, M, J, H, ... follows a pattern where each letter is the 6th letter from the previous letter. So, the next letter in the series would be 6 letters after H, which is N.

Therefore, the letter that comes next in the given alphanumeric series is "N".

Answer: bottom right

Answer:

The reduced echelon form of the given matrix B is [ 1 0 0 -5 | 0 ], [ 0 1 0 3 | 0 ], and [ 0 0 1 0 | 0 ]. The parametric description of the set of solutions for the given system of linear equations is { [5x4, -3x4, 0, x4] | x4 ∈ R }.

Step-by-step explanation:

Using row operations to reduce the matrix B to reduced row echelon form, we have:

[ 1 3 -5 4 | 0 ]

[ 1 4 -8 7 | 0 ]

[-3 -7 9 -6 | 0 ]

R2 - R1 -> R2

R3 + 3R1 -> R3

[ 1 3 -5 4 | 0 ]

[ 0 1 -3 3 | 0 ]

[ 0 2 4 6 | 0 ]

R1 - 3R2 -> R1

R3 - 2R2 -> R3

[ 1 0 4 -5 | 0 ]

[ 0 1 -3 3 | 0 ]

[ 0 0 10 0 | 0 ]

R3/10 -> R3

[ 1 0 4 -5 | 0 ]

[ 0 1 -3 3 | 0 ]

[ 0 0 1 0 | 0 ]

R2 + 3R3 -> R2

R1 - 4R3 -> R1

R2 + 3R3 -> R3

[ 1 0 0 -5 | 0 ]

[ 0 1 0 3 | 0 ]

[ 0 0 1 0 | 0 ]

Therefore, the reduced echelon form of the matrix B is:

[ 1 0 0 -5 | 0 ]

[ 0 1 0 3 | 0 ]

[ 0 0 1 0 | 0 ]

asterisk

can you make it step by step easy to understand

Certainly! Here are the steps to find the reduced row echelon form of the matrix B = [1, 3, -5, 4, 1, 4, -8, 7, -3, -7, 9, -6]:

Write the matrix in augmented form, with a vertical line separating the coefficients from the constant terms.

[ 1 3 -5 4 | 0 ]

[ 1 4 -8 7 | 0 ]

[-3 -7 9 -6 | 0 ]

Use row operations to transform the matrix into row echelon form. The goal is to create zeros below the leading entries (the first nonzero element) in each row. Here are the steps:

a. Subtract the first row from the second row, and subtract 3 times the first row from the third row:

[ 1 3 -5 4 | 0 ]

[ 0 1 -3 3 | 0 ]

[ 0 2 4 6 | 0 ]

b. Subtract 3 times the second row from the first row, and subtract 2 times the second row from the third row:

[ 1 0 4 -5 | 0 ]

[ 0 1 -3 3 | 0 ]

[ 0 0 10 0 | 0 ]

c. Divide the third row by 10 to create a leading 1 in the third row:

[ 1 0 4 -5 | 0 ]

[ 0 1 -3 3 | 0 ]

[ 0 0 1 0 | 0 ]

Use row operations to transform the matrix into reduced row echelon form. The goal is to create leading 1's in each row, and zeros above and below the leading 1's. Here are the steps:

a. Subtract 4 times the third row from the first row, and subtract 3 times the third row from the second row:

[ 1 0 0 -5 | 0 ]

[ 0 1 0 3 | 0 ]

[ 0 0 1 0 | 0 ]

The matrix is now in reduced row echelon form. The leftmost nonzero entry in each nonzero row is 1, and each leading 1 is the only nonzero entry in its column. The rows are arranged so that all rows with all zeros are at the bottom of the matrix.

Therefore, the reduced row echelon form of the matrix B is:

[ 1 0 0 -5 | 0 ]

[ 0 1 0 3 | 0 ]

[ 0 0 1 0 | 0 ]

For (b):

From the reduced echelon form obtained in part (a), we can write the system of equations as:

x1 + 0x2 + 4x3 = -5

0x1 + x2 - 3x3 = 3

0x1 + 0x2 + x3 = 0

We can solve for the basic variables (x1, x2, x3) in terms of the free variable(s):

x1 = -5 - 4x3

x2 = 3 + 3x3

x3 = free

Therefore, the general solution to the system of equations is:

x = [-5 - 4x3, 3 + 3x3, x3]

where x3 is any real number, since it is the free variable. This is the parametric description of the set of solutions. We can also write this solution set in set-builder notation as:

{ [-5 - 4x3, 3 + 3x3, x3] | x3 ∈ R }

This means that any vector in the solution set can be obtained by choosing a value for the free variable x3 and plugging it into the expressions for x1, x2, and x3. For example, if we choose x3 = 0, we get the solution (x1, x2, x3) = (-5, 3, 0). If we choose x3 = 1, we get the solution (x1, x2, x3) = (-9, 6, 1), and so on.

Step-by-step explanation:

a) To compare the overall percentage of late deliveries for each delivery service, we need to calculate the total number of late packages and total number of deliveries for each service, and then divide the number of late packages by the total number of deliveries, and multiply by 100 to get the percentage.

For Pack Rats, the total number of deliveries is 400 + 100 = 500, and the total number of late packages is 12 + 16 = 28. Therefore, the percentage of late deliveries for Pack Rats is:

percentage of late deliveries for Pack Rats = (28/500) x 100 = 5.6%

percentage of late deliveries for Boxes R Us = (30/500) x 100 = 6%

Therefore, based on these calculations, Pack Rats has a lower overall percentage of late deliveries compared to Boxes R Us.

b) While Pack Rats has a lower overall percentage of late deliveries compared to Boxes R Us, it's important to note that this decision should not be based solely on this one comparison. It's possible that there are other factors that the company needs to consider, such as the cost of each delivery service or the quality of customer service provided by each company.

Furthermore, the sample size in this trial period may not be large enough to draw a definitive conclusion about the reliability of each service. Therefore, while Pack Rats may be a good choice based on the available data, the company should consider other factors and conduct further research before making a final decision.

The amount of money that Theresa has left is equal to £2,740.

In order to write a linear equation to describe this situation, we would assign variables to the cost of flights for each of them and the cost of accommodation for each of them respectively, and then translate the word problem into a linear equation as follows:

Let the variable a represent cost of flights for each of them.

Let the variable f represent cost of accommodation for each of them.

Since Theresa paid for herself and 11 friends to go on holiday with a flight cost of £339 and accommodation cost of £266, a linear equation to describe this situation is given by;

y = 12(a + b)

y = 12(266 + 339)

y = £7,260

For the amount of money left, we have:

Amount of money left = £10,000 - £7,260
