Answer:

180

Step-by-step explanation:

At the beggining, it says they are stacked in 5 layers which means the number of cubes is divisible by 5.

If the number of cubes equals x:

The least amount of sugar cubes the Jones family could have used is \(61*2\) which equals 122. The most they could've used is \(61*3\) which equals 183.

Based on the information from the Jones family, x is between 122 and 183.

Based on the information from the Connor family, x is between 176 and 264.

Based on the information from both, x is between 176 and 183. The only number that is divisible by 5 between those numbers is 180 cubes.

Answer:

Lemmy ; 2 7/8 miles

Step-by-step explanation:

Given that :

Distance walked by Lemmy:

Saturday = 3 1/2 miles

Sunday = 4 3/4 miles

Total distance walked by Lemmy:

3 1/2 + 4 3/4

7/2 + 19/4

(14 + 19) / 4

33 / 4

= 8 1/4

Miles walked by Ronnie : 5 3/8

Lemmy walked farther because : 8 1/4 > 5 3/8

Number of distance walked farther than Ronnie :

8 1/4 - 5 3/8

33/4 - 43/8

(66 - 43) / 8

= 23/ 8

Answer:

x = 12/7

Step-by-step explanation:

You put:                         What you should have had is:

13x - 3y = 12                   13x - 3y = 12

- x + 3y = 12                    + x + 3y = 12

Now that we have that, we can do

14x = 24

Than, divide 24 by 14

x = 24/14

which we can simplify by dividing both by 2

x = 12/7

We can't simplify it down anymore, so this is our answer.

Answer:

y = (1/3)x + 1

Step-by-step explanation:

A parallel line has the same slope as the reference line.  This means the new equation would have a slope of (1/3).  The y-intercept, -5, needs to be different.  But since the line needs to pass through point (3,2), we need a value of b that will cause that to happen.

We can start with y = (1/3)x + b.  As long as b is not -5, the line will be different and parallel.  To force it through point (3,2), just enter those values and solve for b:

y = (1/3)x + b

2= (1/3)*3 + b

2 = 1 + b

b = 1

The equation becomes y = (1/3)x + 1.

See attached image.

The system of linear equations can be written as an augmented matrix equation as \(\[\begin{bmatrix} 1 & 1 & -1 & 4 \\ \end{bmatrix}\]\) and the solution to the system of linear equations is x = 0, y = 4, z = 0.

(a) The system of linear equations can be written as an augmented matrix equation as shown below:

\(\[\begin{bmatrix} 1 & 1 & -1 & 4 \\ \end{bmatrix}\]\)

where,
the coefficients of x, y, z are 1, 1 and -1 respectively,
and the constant term is 4.

(b) Using Gaussian elimination method to solve the system of linear equations:

\(\[\begin{bmatrix} 1 & 1 & -1 & 4 \\ \end{bmatrix}\]\)

We use the first row as the pivot row and eliminate all the elements below the pivot in the first column. The first operation that we perform is to eliminate the 1 below the pivot, by subtracting the first row from the second row. The first row is not changed, because we need it to eliminate the other elements below the pivot in the next step.

\(\[\begin{bmatrix} 1 & 1 & -1 & 4 \\ 0 & -1 & 1 & -4 \\ \end{bmatrix}\]\)

The second operation is to eliminate the -1 below the pivot, by subtracting the first row from the third row.

\(\[\begin{bmatrix} 1 & 1 & -1 & 4 \\ 0 & -1 & 1 & -4 \\ 0 & 2 & 0 & 8 \\ \end{bmatrix}\]\)

The third operation is to eliminate the 2 below the pivot, by adding the second row to the third row.

\(\[\begin{bmatrix} 1 & 1 & -1 & 4 \\ 0 & -1 & 1 & -4 \\ 0 & 0 & 1 & 0 \\ \end{bmatrix}\]\)

Now, we have reached the upper triangular form of the matrix.
We can solve for z from the third row as:

z = 0

Substituting z = 0 into the second row, we can solve for y as:

-y + 1(0) = -4

y = 4

Substituting y = 4 and z = 0 into the first row, we can solve for x as:

x + 4 - 0 = 4

x = 0

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

x = 0, y = 4, z = 0.

Answer:

  B.  False

Step-by-step explanation:

You want to know if it is true that when each of seven persons in a group shakes hands with each of the other six persons, a total of forty-two handshakes occurs.

The count of 42 handshakes includes every one of 7 shaking hands with each of the remaining 6, without regard to whether they met before.

The count will include A shaking hands with B, and B shaking hands with A. That handshake will be counted twice, so the number 42 overstates the actual number of handshakes by a factor of 2.

It is false that there will be 42 handshakes. (There will be only 21.)

Answer:

Step-by-step explanation:

Let the first no be x

Second number woud be 35-x

So , second equation would be

4*x - (35-x) = 10

5x-35 = 10

5x = 45

x=9

Second number is 35-9 = 26

Answer:

9, 26

Step-by-step explanation:

x = 1st number

y = 2nd number

x + y = 35    →  y = 35 - x

4x - y = 10       substitute y = 35 - x into this equation and solve for x

4x - (35 - x) = 10

4x - 35 + x = 10

5x = 10 + 35

5x = 45

x = 45/5 = 9

Now you can solve for y:

y = 35 - x = 35 - 9 = 26

The figure here is a rectangle.

Using the formula for perimeter and area:

Part a. Fencing that will be used more = 24ft.

Part b. Area of proposed space greater than area of current space

= 276ft²

A quadrilateral with equal angles and parallel opposite sides is referred to as a rectangle. Around us, there are a lot of rectangle items. The length and width of each rectangle serve as its two distinguishing attributes. The width and length of a rectangle, respectively, are its longer and shorter sides.

In the given question,

Length of current space, l = 24ft.

Breadth of current space, b = 16 ft.

Length of proposed space = 24 + 3 + 3 = 30ft.

Breadth of proposed space = 16 + 3 + 3 = 22ft.

Part a.

Perimeter of current space = 2 (l + b)

= 2 × (24 + 16)

= 2× 40

= 80ft.

Perimeter of proposed space = 2 × (30+22)

= 2 × 52

= 104ft.

So, fencing that will be used more = 104 - 80

= 24ft.

Part b.

Area of current space = l × b

= 24 × 16

= 384ft².

Area of proposed space = 30 × 22

= 660ft².

Area of proposed space greater than area of current space = 660 - 384

Step-by-step explanation:

Buying bulk topsoil is less expensive than buying bags of topsoil in this case.

Volume is a measure of the amount of space occupied by a three-dimensional object. It is typically measured in cubic units, such as cubic meters (m³), cubic centimeters (cm³), or cubic feet (ft³).

To find the volume of a simple object such as a cube, rectangular prism, or cylinder, you can use a formula that involves multiplying the length, width, and height of the object. For example, the formula for the volume of a rectangular prism is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.

For more complex objects, such as irregular shapes or those with curved surfaces, you can use techniques such as integration or approximation to find the volume.

First, we need to determine how many cubic feet of topsoil Austin needs to cover his backyard with a 4 inch layer. We can start by calculating the volume of his backyard in cubic feet:

Volume = length x width x depth

Volume = 70 ft x 60 ft x (4 in / 12) ft

Volume = 1400 ft³

So Austin needs 1400 cubic feet of topsoil to cover his backyard with a 4 inch layer.

Option 1: Bags of Topsoil

Each bag of topsoil covers 3 cubic feet, so Austin needs 1400 / 3 = 466.67 bags of topsoil. Since he can only buy whole bags, he will need to buy 467 bags. Each bag costs $2.50, so the total cost of the topsoil would be:

Total cost = number of bags x cost per bag

Total cost = 467 x $2.50

Total cost = $1167.50

Since delivery is free, the total cost of the topsoil is $1167.50.

Option 2: Bulk Topsoil

Bulk topsoil costs $22.00 per cubic yard, and Austin needs 1400 / 27 = 51.85 cubic yards. Since he can only buy whole yards, he will need to buy 52 yards. The cost of the topsoil itself would be:

Cost of topsoil = volume of topsoil x cost per cubic yard

Cost of topsoil = 52 yd³ x $22.00/yd³

Cost of topsoil = $1144.00

There is also a $20 delivery fee, so the total cost of the topsoil would be:

Total cost = cost of topsoil + delivery fee

Total cost = $1144.00 + $20.00

Total cost = $1164.00

Therefore, buying bulk topsoil is less expensive than buying bags of topsoil in this case.

The matching answers and corresponding colors for the holiday lights are: (Slope: 3) Dark Blue, (Slope: -4) Violet, (Slope: 1/4) Red.

To find the slope of a line passing through two points \((x_1, y_1)\ and\ (x_2, y_2)\), we can use the formula:

Slope = \((y_2 - y_1) / (x_2 - x_1)\)

Let's calculate the slopes for each pair of points:

1. (8, 3) and (10, 9):

Slope = (9 - 3) / (10 - 8) = 6 / 2 = 3

2. (2, -3) and (1, 1):

Slope = (1 - (-3)) / (1 - 2) = 4 / (-1) = -4

3. (-4, -8) and (-8, -9):

Slope = (-9 - (-8)) / (-8 - (-4)) = (-9 + 8) / (-8 + 4) = -1 / (-4) = 1/4

Now let's compare the slopes to identify the matching answers:

1. Slope: 3 (Dark Blue)

2. Slope: -4 (Violet)

Answer:

x=9

Step-by-step explanation:

First, distribute the negative sign, changing (2x+9) to -2x-9

next, distribute. 10x+−2x+−9=(−3)(15)+(−3)(−4x)

then, combine like the like terms  (10x+−2x)+(−9)=12x−45

then you get  8x+−9=12x−45, and you will subtract 12x from both sides, resulting in −4x−9=−45. To get -4x by itself, add 9 to both sides

lastly, divide both sides by -4

x=9

Answer:

x = 9

Step-by-step explanation:

Distribute

10x - (2x + 9) = -3 (15 - 4x)

10 − 2 − 9 = − 3 (15 − 4)

Combine like terms

8 − 9 = − 3 (15 − 4 )

Rearrange terms

8 − 9 = − 3 (− 4 + 15)

Distribute

8 − 9 = 12 − 45

Add 9 to both sides of the equation

8 − 9 + 9 = 12 − 45 + 9
