How would you use a yardstick to measure the length of a rug

Answers

1 yardstick is equal to 1 yard, which is also equal to 3 feet. If you line the end of the yardstick up with the end of the rug, you can figure out 3 feet in. Then line the yardstick up at the 3 foot mark to determine where 6 feet is. Keep laying the yardstick across the rug until you have an overall estimate of how many feet you have. Add up the number of times you have laid the yardstick down and multiply by 3 feet.

Step-by-step explanation:

this is good

70 megabytes can do 35 of these picture take up.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that kiara downloaded 264 pictures from her cellphone to her computer. These pictures took up 528 megabytes of space on her computer.

Each picture took up the same amount of space.

We have to find that how many megabytes do 35 of these picture take up.

therefore, we have to first divide the 528 by 264 then multiply it with 35.

So, we get

= 528/264 x 35

= 35 x 2 = 70

Hence, 70 megabytes can do 35 of these picture take up.

The width of a large, rectangle-shaped tree farm is 1.9 kilometers. The best length of the farm is 4.4 kilometers. What is the best estimate of the area of the farm? Estimate 1.9 x 4.4

Answers

To make estimates, we usually round the numbers the nearest integer.
Since 1.9 is closest to 2 than it is to 1, the nearest integer of 1.9 is 2.
Similarly, since 4.4 is closest to 4 than it is to 5, the nearest integer of 4.4 is 4.

Now, to estimate the area of the farm, we are going to multiply our two integers:
Estimated Area of the Farm= [tex]2[/tex]x[tex]4=8[/tex]

Since 8 is between 4 and 10, we can conclude that the best estimate of the area of the farm is: between 4 and 10

Which statement describes if there is an extraneous solution to the equation √x-3 = x-5? A. there are no solutions to the equation, B. the extraneous solution is x = 7, C. the valid solutions are x = 7 and x = 4, or D. the extraneous solution is x = 4

Answers

Remember that an extraneous solution of an equation, is the solution that emerges from solving the equation but is not a valid solution.

Lets solve our equation to find out what is the extraneous solution:
[tex] \sqrt{x-3} =x-5[/tex]
[tex](\sqrt{x-3})^2 =(x-5)^2[/tex]
[tex]x-3=x^2-10x+25[/tex]
[tex]x^2-11x+28=0[/tex]
[tex](x-4)(x-7)=0[/tex]
[tex]x-4=0[/tex] and [tex]x-7=0[/tex]
[tex]x=4[/tex] and [tex]x=7[/tex]

So, the solutions of our equation are [tex]x=4[/tex] and [tex]x=7[/tex]. Lets replace each solution in our original equation to check if they are valid solutions:
- For [tex]x=7[/tex]
[tex] \sqrt{x-3} =x-5[/tex]
[tex]\sqrt{7-3} =7-5[/tex]
[tex] \sqrt{4} =2[/tex]
[tex]2=2[/tex]
We can conclude that 7 is a valid solution of the equation.

- For [tex]x=4[/tex]
[tex] \sqrt{x-3} =x-5[/tex]
[tex]\sqrt{4-3} =4-5[/tex]
[tex] \sqrt{1} =1[/tex]
[tex]1 \neq 1[/tex]
We can conclude that 4 is not a valid solution of the equation; therefore, 4 is a extraneous solution.

We can conclude that the correct answer is: D. the extraneous solution is x = 4

Answer:

D. the extraneous solution is x = 4

Step-by-step explanation:

You want to know the statement that describes if there is an extraneous solution to the equation √x-3 = x-5.

Solution

A straightforward (blind) solution to the problem proceeds by squaring both sides and solving the quadratic:

x -3 = x² -10x +25
x² -11x +28 = 0
(x -7)(x -4) = 0 ⇒ x = 4 or x = 7

When you try these solutions in the original equation, you get ...

√(4 -3) = 4 -5 ⇒ 1 = -1 . . . . . x = 4 is an extraneous solution, choice D

√(7 -3) = 7 -5 ⇒ 2 = 2 . . . . . x = 7 is the solution

Domain

The square root function is only defined for non-negative values, so the left side of the equation is only defined for x ≥ 3.

The left side of the equation produces non-negative values. The right side of the equation will have non-negative values only for x ≥ 5.

Considering the domain of the equation is x ≥ 5, we know that x = 4 cannot be a solution. It can be ignored. This value only arises because squaring the radical allows values of x that require the root to be negative.

Additional comment

The attached graph shows the only solution is x=7, the value that makes the difference between the sides of the equation be zero. We find it useful to write radical equations in the form f(x) = 0, making the x-intercepts of the graph of f(x) be the solution(s). The graphing calculator does not graph the function where it is undefined, so the domain restrictions are automatically accommodated.

How many sides does a regular polygon have if each exterior angle measures 30?

Answers

Sum of exterior angles of every polygon irrespective of number of its sides is 360o . As it is a regular polygon, all exterior angles are equal and are 30o . Hence number of sides of the polygon is 360o30o=12.

The number of sides that the polygon with each exterior angle measuring 30° has is 12.

What is a polygon?

A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.

The sum of all the exterior angles of a regular polygon is always equal to 360°. Therefore, the measure of an exterior angle for a regular polygon is given as,

[tex]\theta = \dfrac{360^o}{n}[/tex]

where n is the number of sides.

Given that the measure of the exterior angle is 30°. Therefore, the number of sides will be,

Final answer:

To find the perimeter of the given quadrilateral, calculate the distance between each pair of consecutive points using the distance formula and sum these distances. The perimeter is the sum of √17 + √20 + 3 + 2 which is 13.59 units.

Explanation:

The question you've asked involves finding the perimeter of a four-sided figure, known as a quadrilateral, with vertices R, S, T, and U located at (-1, 3), (-2, 7), (2, 5), and (-1, 5) respectively. To find the perimeter of this shape, we need to calculate the distance between each pair of consecutive vertices and sum these distances up.

Firstly, use the distance formula – d = √((x2 - x1)² + (y2 - y1)²) – to calculate the length of each side:

RS = √((-2 - (-1))² + (7 - 3)²) = √(1 + 16) = √17=4.12

ST = √((2 - (-2))² + (5 - 7)²) = √(16 + 4) = √20 = 4.47

TU = √((-1 - 2)² + (5 - 5)²) = √(9 + 0) = 3

UR = √((-1 - (-1))² + (3 - 5)²) = √(0 + 4) = 2

Finally, sum these distances to find the perimeter: √17 + √20 + 3 + 2 which comes out to be 13.59 units. The exact perimeter involves square roots since we're dealing with irrational distances.

a. 9g - 3

b. 3g - 9

c. g - 4g

d. 3g + 9

Answer:

a. 9g - 3

Step-by-step explanation:

Sal scored g number of goals this season . Ben has scored 4 times as many goals as Sal . Chun has scored 3 fewer goals than Ben. There goals can be expressed as follows

Sal's goal = g

Ben's goal = 4(g) = 4 × g = 4g

Chun's goal = 4g - 3

sum of their goals = g + 4g + (4g - 3)

sum of their goals = g + 4g + 4g - 3

sum of their goals = 9g - 3

The area covered by the planter is 220¹/₂ in² = 220,5 in²

Further explanation

To solve the above questions, we need to recall some of the formulas as follows:

Area of Square = (Length of Side)²

Perimeter of Square = 4 × (Length of Side)

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Rhombus = 4 × ( Length of Side )

Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )

Let us now tackle the problem !

Given:

Length of Rectangle = L = 3¹/₂ inches

Width of Rectangle = W = 1³/₄ inches

Unknown:

Area of Plainter = A = ?

Solution:

This problem is about Area of Rectangle.

[tex]\texttt{Area of Rectangle} = \texttt{Length} \times \texttt{Width}[/tex]

[tex]\texttt{Area of Rectangle} = 3\frac{1}{2} \times 1\frac{3}{4}[/tex]

A section in a stained glass window is shaped like a trapezoid. The top base is 1 centimeter and the bottom base is 3.5 centimeters long. If the area of the section of glass is 8.1 square centimeters, how tall is the section?

Answers

Final answer:

The height of the trapezoidal section is approximately 3.6 centimeters.

Explanation:

To find the height of the trapezoidal section, we can use the formula for the area of a trapezoid: A = 1/2 * (top base + bottom base) * height. In this case, the top base is 1 centimeter and the bottom base is 3.5 centimeters. We are given that the area is 8.1 square centimeters. Plugging these values into the formula:

8.1 = 1/2 * (1 + 3.5) * height8.1 = 2.25 * heightheight = 8.1 / 2.25height ≈ 3.6 centimeters

Therefore, the height of the trapezoidal section is approximately 3.6 centimeters.

Final answer:

The height of the trapezoidal section of stained glass is calculated using the area formula for trapezoids. With the given measurements, the height is found to be 3.6 centimeters.

Explanation:

To find the height of a trapezoid section in a stained glass window with a top base of 1 centimeter, a bottom base of 3.5 centimeters, and an area of 8.1 square centimeters, we use the formula for the area of a trapezoid, which is Area = 1/2 × (base1 + base2) × height. In this case, base1 is the top base, base2 is the bottom base, and Area is already given as 8.1 cm2.

Plugging the values into the formula gives us:

8.1 = 1/2 × (1 + 3.5) × height

8.1 = 1/2 × 4.5 × height

8.1 = 2.25 × height

To find the height, we divide both sides by 2.25:

height = 8.1 / 2.25

height = 3.6 centimeters

Thus, the height of the trapezoid section is 3.6 centimeters.
