A ​236-inch pipe is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece.

The equation that passes through the point (7, -2) and (11, 5) is y = 4/7x - 9

Equation of the line:

The standard form of the equation of the line is written as

y = mx + b

here

x and y represents the coordinates of the equation

m refers the slope of the equation

b refers the y intercept of the equation

Given,

Here we have the points (7, -2) and (11, 5).

Now we have to find the equation that passes through this points.

If you want to find the equation of the line, we have to find the slope and the intercept of the line.

The slope of the line is calculated by using the given point (7, -2) and (11, 5),

=> m = (11 - 7) / ( 5 - (-2))

=> m = 4/7

Now, we have to use the slope and the point (11, 5) to find the value of y intercept of the equation,

=> 5 = (4/7) (11) + b

=> 35 = 44 + b

=> b = -9

Therefore, the equation that passes through the points is y = 4/7x - 9

The input of a function that can be controlled is the independent variable while the output is the dependent variable thus "Number of hours" and "D" are independent while the amount of muscle mass is the dependent variable.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

An input variable that we can control and manage is said to be an independent variable.

For example in function y = f(x) here we can control variable x so it will be an independent variable.

As per the given,

The number of hours we can spend so will be an independent variable.

The input D will be the independent variable.

The amount of mass muscles depends on age so it will be the dependent variable.

Hence "Number of hours" and "D" are independent while the amount of muscle mass is the dependent variable".

Answer:

y = -2x-13

1) plot the coordinate you have on a graph (starting at (0,0) move to the left until you hit -8 and then up until you are at +3)

2) Since your slope is negative the line will be higher on the left and lower on the right, so starting at the point you have plotted move down 2 units and to the right one unit.

3) Do this until you intersect with the y-axis (at -13), this is your value for 'b'

4) Plug your values for 'b' and 'm' into the slope-intercept equation

1a) The number of whole servings Susan can make from 4.25 pounds of flour if one serving uses ²/₃ is 6.

1b) The quantity of flour Susan has after making 6 servings is ¹/₄ pounds.

2) Garrison can drink ⁷/₈ gallons of lemonade each of the next six days.

3) The student council sold 122 bags of chips.

4) If a container can hold 3¹/₃ ounces of peanuts, 5 containers will hold 16²/₃ ounces.

5) The number of people at the football game (400) last night who were not wearing orange and black is 240.

6) The number of long sleeves in Jordan's outfits is 45.

The numbers and values can be determined using suitable mathematical operations.

The basic mathematical operations used include division, subtraction, and multiplication.

1) The total quantity of flour available = 4.25 pounds

The amount of flour required per serving = ²/₃ pounds

The number of servings from 4.25 pounds = 6³/₈ servings (4.25 ÷ ²/₃)

= 6 servings.

Quantity of flour left = ¹/₄ pounds [4 - 6(²/₃)]

2) The number of lemonades available = 5.5 gallons

The quantity Garrison took on Monday = ¹/₄ gallons (0.25)

The remaining number of gallons = 5.25 gallons (5.5 - 0.25)

The gallons for the remaining 6 days = ⁷/₈ gallons (5¹/₄ ÷ 6)

3) The total amount realized from sales = $73.20

The unit price per bag of chips = $0.60

The units sold = 122 ($73.20 ÷ $0.60)

4) The ounces of peanuts per container = 3¹/₃

The number of containers = 5

The ounces of peanuts for 5 containers = 16²/₃ ounces (3¹/₃ x 5)

5) The total number of people at the game = 400

The proportion of people wearing orange and black = ²/₅

The proportion of people not wearing orange and black = ³/₅ (1 - ²/₅)

The number of people not wearing orange and black = 240 (400 x ³/₅)

6) The total number of outfits in Jordan's closet = 200

The proportion of shirts = ³/₄

The proportion of long sleeve shirts = ³/₁₀

The number of long sleeve shirts = 45 (200 x ³/₄ x ³/₁₀)

Answer:

[tex]15\sqrt{5}[/tex]

Step-by-step explanation:

simplify [tex]\sqrt{20}[/tex] and [tex]3\sqrt{50}[/tex]

 [tex]\sqrt{20}[/tex] simplifies into [tex]\sqrt{5}[/tex]

 so [tex]\sqrt{20}[/tex] =  [tex]\sqrt{4} \sqrt{5}[/tex]

we can simplify [tex]\sqrt{4[/tex] into a whole number

[tex]\sqrt{4[/tex] =2

          =   2[tex]\sqrt{5}[/tex]

   [tex]\sqrt{50[/tex] simplifies into [tex]\sqrt{2[/tex]

   so [tex]\sqrt{50[/tex] =3( [tex]\sqrt{25} \sqrt{2}[/tex])

we can simplify [tex]\sqrt{25}[/tex] into a whole number

[tex]\sqrt{25[/tex] = 5

= 15[tex]\sqrt{2[/tex]

then we add these simplified roots back into the question

2[tex]\sqrt{5}[/tex] + [tex]5\sqrt{2[/tex] -[tex]2\sqrt{5[/tex]

we simplify again as [tex]2\sqrt{5[/tex] cancels out

Answer:

x = 30 degrees

y = 15 degrees

z = 150 degrees

Step-by-step explanation:

Finding x:

2x + 90 + x = 180

3x + 90 = 180

3x = 90

x = 30

x and 2y are alternate interior angles, which means that they are congruent:

x = 2y

30 = 2y

15 = y

x and z are same side interior angles, which means that they are supplementary:

x + z = 180

30 + z = 180

z = 180 - 30

z = 150

Answer: A loss of 6 dollars

Step-by-step explanation:

Step 1 is to determine how many eggs she purchased:

3 dozen eggs * 12 eggs per dozen = 36 eggs purchased

Step 2 is to find the cost of the eggs purchased using the information you gave:

(36 eggs / 6) * 10 dollars = $60 purchase price

Step 3 is to find out how many eggs broke which is calculated like this:

36 total eggs * .25 = 9 broken eggs

Step 4 is to find how much money she made from selling the remaining eggs:

(36 total eggs - 9 broken eggs) * $2 per egg = $54 resale

Step 5 is finding the profit or loss:

$54 resale price - $60 purchase price = $ -6 (aka a 6 dollar loss)

Step-by-step explanation:

The square mural in Olivia's classroom has dimensions x by x.

Then she paints a mural of dimensions: x+5 (the length) by x-2 (the width).

Thus the second mural (the hallway mural) has the shape of a rectangle with dimensions (x+5) by (x-2), so the area of the second mural is

(x+5)(x-2).

each side of the classroom mural is 7 feet means that x = 7 ft,

thus the area of the hallway mural is :

(x+5)(x-2)=(7+5)(7-2)=12*5=60 (square feet)

So the answer is 60 square feet.

The solutions to the rectangles located on the coordinate plane questions in the first page are;

1. Jordan ran a total distance of 6 miles

2. The fourth vertex is located at (5.5, -3.5)

3. The area of the pool is 48 square yards

The area of a figure is the region covered by the closed boundary of the shape or figure.

1. The coordinates of the points expressed as decimals are;

H(-0.75, 0.5), B(1, 0.5), L(1, -0.25), (0.5, -0.25), C(0.5, -0.75), S(-0.75, -0.75)

The distances between the points Jordan visited are;

HB = 1 - (-0.75) = 1.75

BL = |-0.25 - 0.5| = 0.75

LP = |0.5 - 1| = 0.5

PC = |-0.75 - (-0.25)| = 0.5

SC = |-0.75 - 0.5| = 1.25

SH = 0.5 - (-0.75) = 1.25

The total distance Jordan ran = 1.75 + 0.75 + 0.5 + 0.5 + 1.25 + 1.25 = 6

The total distance Jordan ran is 6 miles

2. The shape of the piece of material = A rectangle

The vertices of the rectangle are; (-1.2, -3.5), (-1.2, 4.4) and (5.5, 4.4)

The above vertices indicates that the sides of the rectangle are parallel to the x and y-axis as each two of the three points share a common coordinate

(-1.2, -3.5) and (-1.2, 4.4) represent a vertical side

(-1.2, 4.4) and (5.5, 4.4) represent a horizontal side

Therefore, based on plotting the points on the coordinate plane using MS Excel, we have;

(-1.2, -3.5) and (5.5 ,-3.5) will represent the other horizontal side

(5.5, 4.4) and (5.5, -3.5) represents the other vertical side

The coordinates of the fourth vertex is (5.5, -3.5)

3. The vertices of the pool are;

A(-5, 7), B(1, 7), C(1, -1), and D(-5, -1)

The length of the sides of the pool are;

AB = 1 - (-5) = 6

BC = 7 - (-1) = 8

CD = 1 - (-5) = 6

AD = 7 - (-1) = 8

The length of the rectangular pool = 8 yards

The width = 6 yards

The area of a rectangle = Length × Width

Area of the pool = 8 yard × 6 yards = 48 square yards

-3(4x - 5) = 6(x + 3) + 10

-3(4x - 5) = 6(x + 3) + 10

- 12x + 15 = 6x + 18 + 10

- 12x + 15 = 6x + 28

subtract 6x from both sides of the equation
