Answer:

There are infinite solutions.

Step-by-step explanation:

A system of linear equations can have infinite solutions if the equations are equivalent. This means that one of the equations is a multiple of the other. It also means that every point on the line satisfies all of the equations at the same time.

Step-by-step explanation:

Formula

Given :

Solving :

Answer:

28.26 feet²

Step-by-step explanation:

Substitute the radius in the formula:

⇒ Area of circular rug = πr²

⇒ Area of circular rug = π(6/2)²                                   [Diameter/2 = Radius]

Simplify the R.H.S:

⇒ Area of circular rug = π(3)²

⇒ Area of circular rug = π(9)                                              [(3)² = 3 × 3 = 9]

Take π as 3.14 and simplify:

⇒ Area of circular rug = (3.14)(9)

⇒ Area of circular rug = 28.26 feet²   (Using calculator)

The number of purple T shirts that the Trenton's scouting group made is 15.

A pie chart is a type of graph where a circle is divided into certain sectors where each sector shows a proportion of the whole.

Given is a pie chart or circle graph.

This shows the number of different colored T shirts that the Trenton's scouting group made.

Total number of T shirts = 100

Total degree of a circle = 360°

The circle is divided in to various sections with each section of different degree.

Angle measure for the purple section = 54°

Proportion of purple T shirts to the full T shirts = 54 / 360

                                                                             = 0.15

Number of purple T shirts in total of 100 T shirts = 0.15 × 100

                                                                                = 15

Answer:

The answer is 192.33

Step-by-step explanation:

A coaster measures 7 cm in diameter. The total area of five roller coasters must be determined.

The diameter of the coaster is d = 7 cm

The radius is:

[tex]r =[/tex] [tex]\frac{d}{2}[/tex]

[tex]=[/tex] [tex]\frac{7}{2}[/tex] [tex]cm[/tex]

[tex]= 3.5[/tex] [tex]cm[/tex]

The area of the circle is:

[tex]A =[/tex] [tex]\pi r^{2}[/tex]

= (3.14 x 3.5^2) [tex]cm^{2}[/tex]

[tex]= 38.465[/tex] [tex]cm^{2}[/tex]

We now know that the area required for five coasters is 5 x 38.465 [tex]cm^{2}[/tex]

Answer:

150 sq. in.

Step-by-step explanation:
Because... Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet.

The polynomial expression that represents the floor area of the larger kitchen in square feet is  24z² + 40z + 16

The area of Rectangle is length times of width.

The length-to-width ratio of the original rectangular kitchen is 3 to 2.

Let the width of the original kitchen "w".

Then the length of the original kitchen is length = 3/2×w

We are also told that the length of the original kitchen is 6z feet. We can use this information to solve for the width of the original kitchen:

6z = 3/2×w

w = 4z

So the width of the original kitchen is 4z feet.

To make the kitchen larger, we add four feet to each original dimension. The new length is:

length = 6z + 4 feet

width = 4z + 4 feet

Area = (6z + 4 feet) × (4z + 4 feet)

Multiplying out the terms, we get:

Area = 24z² + 40z + 16 square feet

Therefore, the polynomial expression that represents the floor area of the larger kitchen in square feet is  24z² + 40z + 16

Answer: the answer is 27.92

Step-by-step explanation: if you right it vertical and line the desimals you will get the answer

Answer:

a) Infinite solutions = intersect at every point (2 of the same line)

m = rise/run = 3/2

b = y-intercept = (0, -3)

y = 3/2x - 3

b) No solutions = no point of intersection (parallel lines)

m = 3/2 (same slope b/c parallel)

b = (0, 2)

y = 3/2x + 2

c) One solution = one point of intersection

Solution = (4, 3)

y - y₁ = m (x - x₁)

y - 2 = m (x - 2)

m = [tex]\frac{y2-y1}{x2-x1}=\frac{3-2}{4-2} =\frac{1}{2}[/tex]

y - 2 = 1/2 (x - 2)

y = 1/2x + 1

Check to see if (4, 3) is the solution to the system:

y = 1/2x + 1

y = 3/2x - 3

1/2x + 1 = 3/2x - 3

1 = 2/2x - 3

x = 4 ✅

y = 1/2(4) + 1 = 3 ✅

Answer:

10 Classroom

Step-by-step explanation:

Since,

Custodian clean 2 classrooms in 15 minutes

Then ,

Let's see how many minutes does it takes for a custodian to clean for 1 classroom

To Find that we have to divide the given minutes by the given classroom.

15/2 = 7.5

Hence, in 7.5 minutes a custodian clean 1 classroom

Therefore:

Classroom to minutes:

1 = 7.5

2 = 15

3 = 22.5

4 = 30

5 = 37.5

6 = 45

7 = 52.5

8 = 60

9 = 67.5

10 = 75

11 = 82.5

Hence, we round to the nearest number:

which is 10 classroom in 75 minutes.

For this reason, the answer is about 10 classroom

Answer:

Initially, as x increases, y is constant.

Afterward, the slope of the graph of the function equals 2 for all x between x = 3 and x = 5.

The slope of the graph equals -1 for x between x = 5 and x = 9.

The greatest value of y is y = 4, and it occurs when x = 5.

Step-by-step explanation:

Initially, the graph of the function is flat. The quantity y remains constant as x increases from x = 0 to x = 3. The linear equation that corresponds to the function in that region is y = 0. The slope is m = 0 because the graph is a horizontal line. The graph of the function starts to increase starting at x = 3. The slope, rise/run, once we solve it, is equal to 2 for when x is between 3 and 5. After x = 5, y starts to decrease as x increases. The slope of the graph between x = 5 and x = 9 is -1. The maximum value of y occurs at the top of the bump in the graph. The coordinates of the top of the bump are (5,4). Therefore, the maximum value is y = 4, and it occurs when x = 5.

The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

Step-by-step explanation:

Eldora and Finn went to an office supply store together

Eldora bought 15 boxes of paper clips and 7  packages of index cards for a total cost of $55.40

Finn bought 12 boxes of paper clips and 10 packages of  index cards for a total cost of $61.70

We need to find the cost of one box of paper clips and the cost of one package of  index cards

Assume that the cost of one box of paper clips is $x and the cost of one package of  index cards is $y

∵ x represents the cost of one box of paper clips

∵ y represents the cost of one package of  index cards

∵ Eldora bought 15 boxes of paper clips and 7  packages of

  index cards for a total cost of $55.40

∴ 15x + 7y = 55.4 ⇒ (1)

∵ Finn bought 12 boxes of paper clips and 10 packages of  

  index cards for a total cost of $61.70

∴ 12x + 10y = 61.7 ⇒ (2)

Now we have system of equations to solve it

Multiply equation (1) by -10 and equation (2) by 7 to eliminate y

∵ -10(15x) + -10(7y) = -10(55.4)

∴ -150x - 70y = -554 ⇒ (3)

∵ 7(12x) + 7(10y) = 7(61.7)

∴ 84x + 70y = 431.9 ⇒ (4)

Add equations (3) and (4)

∵ (-150x + 84x) + (-70y + 70y) = (-554 + 431.9)

∴ -66x = -122.1

- Divide both sides by -66

∴ x = 1.85

Substitute the value of x in equation (1) or (2) to find y

∵ 12(1.85) + 10y = 61.7

∴ 22.2 + 10y = 61.7

- Subtract 22.2 from both sides

∴ 10y = 39.5

- Divide both sides by 10

∴ y = 3.95

The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95
