Answer:
Area of the walkway border is 736 ft²
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides and four angles) with two pairs of opposite and parallel sides. All angles in a rectangle are 90 degrees each. Also, opposite sides are equal.
The entire pool area has a length of 60 feet and width of 40 feet. The area of the entire pool area is:
Area of entire pool = length * width = 60 feet * 40 feet = 2400 ft²
The area of entire pool
A walkaway border of 4 ft is made around the pool area. There is a decrease of 4 ft round the sides of the pool area.
Therefore length of pool = length of entire pool area - 4 feet border at left - 4 feet border at right = 60 ft - 4 ft - 4 ft = 52 ft
width of pool = width of entire pool area - 4 feet border at top - 4 feet border at bottom = 40 ft - 4 ft - 4 ft = 32 ft
Therefore the pool is 52 ft × 32 ft
Area of pool = length * width = 52 ft * 32 ft = 1664 ft²
Area of the walkway border = Entire pool area - Area of pool = 2400 ft² - 1664 ft² = 736 ft²

Step-by-step explanation:
Answer: 
Step-by-step explanation:
f(x) = -3x² - 6x
<u>Requirements of the question</u>
Find the value of f(-9)
<u>Substitute values into the given function</u>
f(x) = -3x² - 6x
f(9) = -3 (-9)² - 6 (-9)
<u>Simplify the exponent</u>
f(9) = -3 (81) - 6 (-9)
<u>Simplify by multiplication</u>
f(-9) = (-243) - (-54)
<u>Simplify by subtraction</u>

Hope this helps!! :)

A binomial distribution has the following properties;
1. There is a fixed number of trials.
2. Each trial is independent of the others.
3.Each trial has a constant probability of success.
4. There are only two possible outcomes, 'success' and 'failure'.
Statements B and D meet the requirements for the variable X to have a binomial distribution.
Given:
Height of Isabelle = 62 inches
Shadow of Isabelle = 93 inches
Shadow of tree = 279 inches
To find:
The height of the tree.
Solution:
Let height of tree be x.
Ratio of height to shadow for Isabelle and tree are


The shadow of Isabelle and tree are proportional to their shadows. So, both ratios must be equal.

Multiply both sides by 279.



Therefore, the height of tree is 186 inches.
