Step-by-step explanation:

Based on the scale factor of 1:6, if the area of the activity field is 21,600 square feet, the area of the playground is equal to 3,600 square feet.

Given the following data:

Scale factor = 1:6

Area of the activity field = 21,600 square feet.

A scale factor can be defined as the ratio of two (2) corresponding length of sides, area, or diameter in two similar geometric figures such as equilateral triangles, river, planets in our solar system, etc.

Let E represent the area of the elementary playground.

Let H represent the area of the high school activity field.

Therefore, a mathematical expression which relates the area of the elementary playground to the area of the high school activity field is given by:

E : H 1:6 = x : 21,600

Evaluating, we have:

1/6 = x/21,600

Cross-multiplying, we have:

6x = 21,600

x = 21,600/6

x = 3,600 square feet.

Answer:

Here both a & b are positive integers that are obtained from the expression (-a)(-b).

Step-by-step explanation:

It is given that a and b are both positive integers, therefore -a and- b are negative integers.

Now, using this we need to simplify the expression (-a)(-b);

Firstly, let us understand what are integers and types of integers;

The collection of whole numbers and negative numbers is known as an integer in mathematics.

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers.

The inverse additives of the equivalent positive numbers are the negative numbers.

Now, let us understand what are positive and negative integers;

In fact, positive integers are a subset of the wider class of numbers known as integers.

Integers with a negative value are those that are less than zero. They exclude decimals and fractions.

Furthermore, the expression given is (-a)(-b) which is the product of two negative integers.

=> (-a)(-b)

=> ab

Therefore, here both a & b are positive integers that are obtained from the expression (-a)(-b).

Commutative Property of Multiplication

Step-by-step explanation:

The Commutative Property of Multiplication essentially states that constants and variables can be multiplied in any order and the product will not change.

For example, the multiplication of 5 x 4 = 20 and 4 x 5 = 20 are equivalent. No matter what, you will get the same product.

Both equations utilize the distributive property, which states that an expression a(b ± c) can be multiplied to create ab ± ac. As such, we can rearrange the a to either the front or end of the expression and retrieve the same results.

The y-coordinate of the point on the line when x = 8 is -1

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are

Slope, m = 1/2

Point, (x1, y1) = (2, -4)

The linear equation is calculated as

y = m(x - x1) + y1

So, we have

y = 1/2(x - 2) - 4

When x = 8, we have

y = 1/2(8 - 2) - 4

Evaluate

Answer:

11.  17.7 units

12.  24.7 units

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.  

To find the perimeter of a polygon, sum the lengths of its sides.

Use the distance formula to find the length of each side.

[tex]\boxed{\begin{minipage}{4.7 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

Given points:

Use the distance formula to find the length of each side of ABC:

[tex]\begin{aligned}AB & = \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& = \sqrt{(2-(-2))^2+(5-1)^2}\\& = \sqrt{4^2+4^2}\\& = \sqrt{16+16}\\& = \sqrt{32}\end{aligned}[/tex]

[tex]\begin{aligned}BC & = \sqrt{(x_C-x_B)^2+(y_C-y_B)^2}\\& = \sqrt{(5-2)^2+(1-5)^2}\\& = \sqrt{3^2+(-4)^2}\\& = \sqrt{9+16}\\& = \sqrt{25}\\& = 5\end{aligned}[/tex]

[tex]\begin{aligned}AC & = \sqrt{(x_C-x_A)^2+(y_C-y_A)^2}\\& = \sqrt{(5-(-2))^2+(1-1)^2}\\ & = \sqrt{7^2+0^2}\\ & = \sqrt{49}\\ & = 7\end{aligned}[/tex]

To find the perimeter, sum the sides:

[tex]\begin{aligned}\sf Perimeter & = AB+BC+AC\\& = \sqrt{32}+5+7\\& = 4\sqrt{2}+12\\& = 17.7\;\sf units\;(nearest\:tenth)\end{aligned}[/tex]

Given points:

After plotting the given points, it is clear that the polygon is a parallelogram. As the opposite sides of a parallelogram are equal in length:

Therefore, we only need to find the length of two sides to calculate the perimeter.

Use the distance formula to find AB and BC:

[tex]\begin{aligned}AB & = \sqrt{(1-(-3))^2+(6-5)^2}\\& = \sqrt{4^2+1^2}\\& = \sqrt{16+1}\\& = \sqrt{17}\end{aligned}[/tex]

[tex]\begin{aligned}BC & = \sqrt{(3-1)^2+(-2-6)^2}\\& = \sqrt{2^2+(-8)^2}\\& = \sqrt{4+64}\\& = \sqrt{68}\end{aligned}[/tex]

Therefore, the perimeter of ABCD is:

[tex]\begin{aligned}\sf Perimeter & = 2(AB+BC)\\& = 2(\sqrt{17}+\sqrt{68})\\& = 6\sqrt{17}\\& =24.7\;\sf units\;(nearest\:tenth)\end{aligned}[/tex]

The number of apple trees the orchard have is 3533.

The apple orchard  has honey crisp trees and McIntosh trees.

The orchard has 1603 honey crisp trees.

It has 327 more McIntosh trees than honey crisp trees.

Therefore,

number of honey crisp trees = 1603

number of McIntosh trees = 327 + 1603

number of McIntosh trees = 1930

Therefore, the number of apples trees the orchard have can be calculated as follows:

number of apples trees = number of McIntosh trees + number of honey crisp trees

number of honey crisp trees = 1603

number of McIntosh trees = 1930

number of apples trees = 1930 + 1603

number of apples trees = 3533

The horizontal distance as a function of d can be given as h = √(d + 7200) (d - 7200).

It is given in the question that:

Height at which blimp is flying (AB)= 7200 feet

The slanted distance to the pagoda (BC) = d feet

The horizontal distance (AC) = h

Let the angle made between slanted distance and horizontal distance be θ.

So, cosθ = AC/BC

cosθ = h/d

and also, sinθ = AB/BC

sinθ = 7200/d

Now, we know from the first trigonometric identity that cos²θ = 1 - sin²θ.

=> (h/d)² = 1 - (7200/d)²

=> (h/d)² = (d² - 7200)/d²

=> h² = d² - 7200

=> h = √(d² - 7200)

=> h = √(d + 7200) (d - 7200)

Thus, the horizontal distance as a function of d can be given as h = √(d + 7200) (d - 7200).
