Answer:

We can start the problem by using the formula for the area of a rectangle:

Area = length x width

The total area of the pool and the walkway is given as 360 square feet. Let's assume that the width of the walkway is w feet. Then, the dimensions of the entire area can be represented as (8 + 2w) by (10 + 2w) feet, since there is an additional width of w feet on both sides of the pool. Therefore, we can set up the equation:

(8 + 2w) x (10 + 2w) = 360

Expanding the left side and simplifying, we get:

4w^2 + 36w - 80 = 0

We can solve for w using the quadratic formula:

w = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 4, b = 36, and c = -80. Substituting these values into the formula, we get:

w = (-36 ± sqrt(36^2 - 4(4)(-80))) / 8

w = (-36 ± sqrt(1872)) / 8

w ≈ -5.6 or w ≈ 3.6

Since the width cannot be negative, we can discard the first solution. Therefore, the width of the walkway should be approximately 3.6 feet.

your given information is important because your first piece of info is the y intercept. The y intercept can be interpreted as (0,2). this is your initial point.

once you have that point, you can then use the slope to finish off your linear function. the slope is rise/run.

this means that you have to travel in the y direction, which is your rise. this means you have to go either in the positive or negative, depending on the number. in this case, it's -6, so we would go down 6.

then we would run 5 units in the x direction and same like the x it would be depending on the number being positive or negative. since we have a +5 it means we have to move 5 units to the right should have a graph that looks like a (\).

Angles 1 = 2 = 3 = 98° and 4 = 82° are measured.

The right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection. The image serves as a right angle indicator. The angle formed when two chords cross paths inside of a circle is equal to half the sum of the chords' intercepted arcs. Hence, m1 = 50° and m2 = 130°.

The other angle measurements can be calculated using the diagram as follows:

∠1: ∠1 is a vertical angle to ∠2, so it is also 98°.

∠3: ∠3 is a corresponding angle to ∠2, so it is also 98°.

∠4: ∠4 and ∠2 form a straight angle, which means they add up to 180°. Therefore, ∠4 = 180° - ∠2 = 180° - 98° = 82°.

So, the angle measures are:

∠1 = ∠2 = ∠3 = 98°

The shape that has the same perimeter but a different area than Sheri's design is option D.

What is perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.

The figure contains sides with the measurements, 2 units, 4 units, 4 units, 2 units, 2 units, and 2 units.

The perimeter of the figure will be sum of all sides -

Perimeter = 2 + 4 + 4 + 2 + 2 + 2

Perimeter = 16 units

Therefore, the figure has perimeter of 16 units.

The area of the figure can be determined by adding the area of rectangle and square.

Side of the square measures 2 units.

The length of the rectangle is 2 units.

The breadth of the rectangle is 4 units.

So, the equation will be -

Area = Area of rectangle + Area of square

Area  = (l × b) + (side)²

Area  = (2 × 4) + (2)²

Area  = 8 + 4

Area  = 12 units²

Therefore, the figure has area of 12 units².

The diagram in option D contains sides with the measurements, 3 units, 1 unit, 1 unit, 3 units, 4 units, and 4 units.

The perimeter of the figure will be sum of all sides -

Perimeter = 3 + 1 + 1 + 3 + 4 + 4

Perimeter = 16 units

Therefore, the figure has perimeter of 16 units.

The area of the figure can be determined by adding the area of the two rectangles.

The length of the first rectangle is 1 unit.

The breadth of the first rectangle is 3 units.

The length of the second rectangle is 3 units.

The breadth of the second rectangle is 4 units.

So, the equation will be -

Area = Area of rectangle 1 + Area of rectangle 2

Area  = (l × b) + (l × b)

Area  = (1 × 3) + (3 × 4)

Area  = 3 + 12

Area  = 15 units²

Therefore, the figure has area of 12 units².

Step-by-step explanation:

Therefore, the height range that encompasses 99.7% of adolescent women is roughly between 55.9 and 68.1 inches.

It reveals the average deviation of each number from the norm. When it comes to normally distributed, a large standard deviation denotes that values are typically out of the mean, whereas a smaller standard deviation denotes that values are grouped closely around the mean.

The 68-95-99.7 rule is a way to remember the percentage of data that falls within certain numbers of standard deviations from the mean in a normal distribution. Specifically:

Using this rule, we can answer the following questions:

About 68% of young women have heights within 1 standard deviation of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 1 standard deviation from the mean:

64 inches ± 2.7 inches

So the range of heights that includes about 68% of young women is approximately 61.3 inches to 66.7 inches.

    2. What is the range of heights that includes about 95% of young women?

About 95% of young women have heights within 2 standard deviations of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 2 standard deviations from the mean:

64 inches ± 2(2.7 inches)

So the range of heights that includes about 95% of young women is approximately 58.6 inches to 69.4 inches.

     3. What is the range of heights that includes about 99.7% of young women?

About 99.7% of young women have heights within 3 standard deviations of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 3 standard deviations from the mean:

64 inches ± 3(2.7 inches)

So the range of heights that includes about 99.7% of young women is approximately 55.9 inches to 68.1 inches.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To calculate the profit for selling 300 vetkoek every week, we need to first calculate the total revenue generated and the total cost of producing the vetkoek.

Total revenue = Price per vetkoek x Number of vetkoek sold

Total revenue = 10 x 300 = 3000

Total cost = Cost per vetkoek x Number of vetkoek sold

Total cost = 3.80 x 300 = 1140

Profit = Total revenue - Total cost

Profit = 3000 - 1140 = 1860

Answer:

Step-by-step explanation:

The required quotient of the expression 16x⁻² - 8x⁻² - 2x⁻² divided by 2x is 4x⁻³ - x⁻¹⁰.

Arithmetic involves the basic operations of addition, subtraction, multiplication, and division, as well as more advanced operations such as exponents, roots, logarithms, and trigonometric functions.

Here,
To simplify the given expression, we can start by factoring out the common factor of 2x from the numerator. This gives:

(16x⁻² - 8x⁻² - 2x⁻⁹) / 2x

Next, we can simplify the terms in the numerator by combining the like terms:

= (4x⁻² - x⁻⁹) / x

= 4x⁻²⁻¹ - x⁻⁹⁻¹
= 4x⁻³ - x⁻¹⁰

= 4x⁻³ - x⁻¹⁰

The missing side length is equal to 9 yd.

The rectangle is a quadrilateral.  The classification for quadrilaterals is given by the length of sides and angles. For a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

A rectangle is a geometric figure that has 4 sides called: length and width (W). Due to its characteristics, the rectangle presents two lengths (L) and two widths (W).

For solving this question, you should:

        The figure is composed of two rectangles:

          Rectangle 01 whose sides are: 6 yd (W) and 16 yd (L).

          Rectangle 02 whose sides are: 8 yd (W) and 7 yd (L).

If the length (L) of rectangle 01 is 16 yd, which is equal to the sum between the missing side and the length of rectangle 02 (7 yd). Thus

      16=s+7

      s=16-7

      s=9
