The cost of each bag of flour is $ 18.85 and the cost of each bag of $ 25.7 which a wholesale food supplier charges for each bag of flour and for each bag of sugar.

Given that:

The cost of each bag of flour = x dollars

The cost of each bag of sugar = y dollars

Bakery A purchases seven bags of flour and five bags of sugar for a total cost of $260.45.

Bakery B purchases five bags of flour and three bags of sugar for a total cost of $171.35.

Making equation from both the above statements. We get,

7x + 5y = 260.45 ...... (1)

5x + 3 y = 171.35 ....... (2)

Multiplying equation (1) by 5 and equation (2) by 7. We get the value,

35x + 25y = 1302.25 ....... (3)

35x + 21y = 1199.45 ........ (4)

Subtracting equation (4) from (3). We get,

4y = 102.80

=> y = $ 25.70

Putting the value of y in equation (1). We get,

7x + 25.70 x 5 = 260.45

7x = 260.45 - 128.5

7x = 131.95/7

=> x = $ 18.85

Hence, we can say that a wholesale food supplier charges 18.85 dollars for each bag of flour and 25.7 dollars for each bag of sugar.

The monthly bill for 20 gallons of water is $88.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

A water bottling company charges $8 per month for their water dispenser and $4 for each gallon of water delivered.

If you have g gallons of water delivered in a month.

Then, the equation to represent the  amount of your bill for that month.

8+ 4g

Now, for g=20 the amount of bill would be

Answer:

(- 1, 3 )

Step-by-step explanation:

2x + 3y = 7 → (1)

- 2x + 4y = 14 → (2)

add (1) and (2) term by term to eliminate x

(2x - 2x) + (3y + 4y) = (7 + 14)

0 + 7y = 21

7y = 21 ( divide both sides by 7 )

y = 3

substitute y = 3 into either of the 2 equations and solve for x

substituting into (1)

2x + 3(3) = 7

2x + 9 = 7 ( subtract 9 from both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

As a check

substitute the values of x and y into the left side of both equations and if equal to the right side in both equations then the values of x and y are true.

(1) 2(- 1) + 3(3) = - 2 + 9 = 7 ← true

(2) - 2(- 1) + 4(3) = 2 + 12 = 14 ← true

then (- 1, 3 ) is the solution to the system

Answer:39.65

Step-by-step explanation:

turn 6.5% to 0.065

610 x 0.065=39.65

The inequality will be 3.70x ≤ 145 and the number of items that you can by is  x ≤ 39

Total budget that you have = $145

The price of each item = $3.70

Consider the number of items = x

The inequality will be

3.70x ≤ 145

We have to solve the inequality to find the number of items

3.70x ≤ 145

Divide 3.70 on the both side of the inequality

3.70x / 3.70 ≤ 145 / 3.70

x ≤ 39.18

x ≤ 39

The number of items that you can buy is x ≤ 39

Hence, the inequality will be 3.70x ≤ 145 and the number of items that you can by is  x ≤ 39

Answer:

x = 0.08

Step-by-step explanation:

2x²+ 8x - 1 = 0

4x + 8x - 1 = 0

12x - 1 = 0

Add 1 to the -1 and to the 0 too

12x = 1

Divide both side

x = 0.08

The value of x is 17, y is 2 and length of DF is 20.

Basic Proportionality Theorem (can be abbreviated as BPT) states that, if a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion.

For x

DG = GE ( Given )

DG + GE = DE

DE = 2(DG)

DG/DE = 1/2

hence GH/EF = 1/2

By Basic Proportionality Theorem ( BPT )

(x – 3) / 28 = 1/2

after cross multiplication

2(x – 3) = 28

2x – 6 = 28

2x = 34

x = 17

For y

By Basic Proportionality Theorem (BPT) to side DF

DF = 2(DH)

DH/DF = 1/2

(y + 8) / (y + 8 + x – 7) = 1/2

after cross multiplication

2(y + 8) = y + 8 + x – 7

put x = 17

2(y + 8) = y + 8 + 17 – 7

2(y + 8) = y + 18

2y + 16 = y + 18

2y = y + 2

2y – y = 2

y = 2

DF = 2(2+8)

     = 2(10)

     = 20

Hence, x is 17, y is 2 and DF is 20.

Given,

We require the following inputs to determine the probability that both the base-9 representation and the base-11 representation are three-digit numbers:

The base-11's lowest 3-digit number is 100.

The comparable number is 121 when expressed in base 10.

888 is the biggest 3-digit base-9 number.

The corresponding number is 728 when expressed in base 10.

As a result, there are the following possibilities:

Possibilities = 728 - 121 + 1

Possibilities = 608

The total number of 3-digit base-10 numbers is

Count = 999 - 100 + 1

Count = 900

The necessary probability is:

P = 608/900

Functional dependency SSN --> Name exists in the table STUDENT is TRUE, The correct option is (A)

due to the fact that a student ID is a primary key in a table and that (StudentID, SSN) can also combine to form a composite key that can be used to identify a record in a table in a unique way. The augmented functional dependency between the StudentID and SSN enables you to locate additional data in the table. However, using only StudentID will also assist you in finding data in the table.

Since it could be a candidate key, this is true because it can be used in part of augmented functional dependency.

Thus, the SSN matches the name in the STUDENT table.

Step-by-step explanation:

I went a weird way to get this.  I wrot the line in the slope intercept form and  then converted it to the standare form.

For the slope intercept form I need a slope and a y interctp.  I used the two points given to find the slope.  The slope is the change in y over the change in x.  From the points the y values are 3 and -1.  The x values are 1.2 and -4

[tex]\frac{3 - -1}{\frac{1}{2}- - 4 }[/tex] = [tex]\frac{3+1}{\frac{1}{4}+4 }[/tex] = [tex]\frac{4}{\frac{9}{2} }[/tex]

4 ÷[tex]\frac{9}{2}[/tex] = [tex]\frac{4}{1}[/tex] x [tex]\frac{2}{9}[/tex] = [tex]\frac{8}{9}[/tex]

[tex]\frac{8}{9}[/tex] is the slope

Now to find the y intercept

I will use

slope [tex]\frac{8}{9}[/tex] (m)

y = -1            from the point (-4,-1) given

x = -4            from the point (-4,-1) given

y=mx + b

-1 = [tex]\frac{8}{9}[/tex](-4) + b

-1 = [tex]\frac{-32}{9}[/tex]x + b       Add [tex]\frac{32}{9}[/tex] to both sides

[tex]\frac{23}{9}[/tex] = b

y = [tex]\frac{8}{9}[/tex]x + [tex]\frac{23}{9}[/tex]  Multiply all the way thorugh by 9

9y = 8x + 23  Subtract 9y from both sides

0 = 8x -9y + 23  Subtract 23 from both sides

-23 = 8x -9y

or

8x -9y = -23

A graph which represents the linear function y = -2x is: graph B.

In Mathematics, a graph can be defined as a type of chart that is typically used for the graphical representation of data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis respectively.

Generally speaking, the graph of any proportional relationship is characterized by a straight line with the data points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) either increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.

In this context, we can reasonably infer and logically deduce that the relationship between x-values and y-values in the graph of y = -2x is proportional as it passes through the origin (0, 0).

Volume of the rectangular solid in cubic inches for the given measures of edges 1. 5 feet by 1½ feet by 3 inches is equal to 972 cubic inches.

As given in the question,

Given measures of edges of the rectangular solid is equal to :

1. 5 feet by 1½ feet by 3 inches

Length = 1.5 feet

Conversion 1 feet = 12 inches

1.5 feet = 1.5 × 12

            = 18 inches

Width = 1½ feet

          = 3/2 feet

          = ( 3/2 ) × 12

          = 18 inches

height = 3 inches

Volume of the rectangular solid = length × width × height

                                                     = 18 × 18 × 3

                                                     = 972 cubic inches
