Two equal rectangular lots are enclosed by fencing the perimeter of a rectangular lot and then putting a fence across its middle. If each lot is to contain 2,700 square feet, what is the minimum amount of fence (in ft) needed to enclose the lots (include the fence across the middle)

Answers

Answer:

360 feet

Step-by-step explanation:

Area = 2XY = 2 · 2,700 = 5,400

Perimeter = (2 · 2X) + 3Y = 4X + 3Y

Y = 5,400 / 2X = 2,700 / X

Perimeter = 4X + 8,100/X

P'(x) = 4 - 8,100/X² = 0

4 = 8,100/X²

X² = 8,100 / 4 = 2,025

X = √2,025 = 45

Y = 2,700 / 45 = 60

Perimeter = (4 · 45) + (3 · 60) = 180 + 180 = 360 feet

At its highest point, the elevation of a county is 5,776 feet above sea level. At its lowest point, the elevation of the county is 6 feet below sea level. Write an expression using integers to represent the difference between the elevations.
(Do not simplify.)

Answers

The expression that represents the elevation is 5,776-(-9)=5,785.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that at its highest point, the elevation of a county is 5,776 feet above sea level. At its lowest point, the elevation of the county is 6 feet below sea level.

The expression will be generated by subtracting the two heights.

5,776-(-9) = 5,785.

Therefore, the expression that represents the elevation is 5,776-(-9)=5,785.

The local newspaper has letters to the editor from 70 people. If this number represents 4% of all of the newspapers readers, how many readers does the newspaper

Answers

Final answer:

The local newspaper has 1,750 readers.

Explanation:

To find the total number of newspaper readers, we can set up a proportion using the given information. Let x be the total number of newspaper readers. We can write the proportion:

70/ x = 4/100

Cross multiplying, we have:

70 * 100 = 4 * x

7000 = 4 * x

Dividing both sides by 4, we find:

x = 7000 / 4

x = 1750

Therefore, the newspaper has 1,750 readers.
