Answer:

Step-by-step explanation:

-60

Step-by-step explanation:

Increase in population is given by positive sign

Decrease in population is represented by negative sign

Change in population in 1 year = -300\5

= -60

Town's population faces a decrease of 60 residents each year.

X^2 + 10x + 11 = 0
x^2 + 10x = -11
x^2 + 10x + 25 = -11 + 25
(x + 5)^2 = 14 <===
x + 5 = (+-) sqrt 14
x = -5 (+-) 3.74

x = -5 + 3.74 = -1.26 <== solution
x = -5 - 3.74 = - 8.74 <== solution

David says he has 2/3 of a pipe length left, while Don says he has 11/16 of a length left. Which person has the longest section

Kruka [31]

Answer:

Don

Step-by-step explanation:

1. We make the fractions have common denominators so it is easier to compare them. We can do this buy multiplying 2/3 by a factor of 16, so it becomes 32/48. For 11/16, we multiply by a factor of 3 so it becomes 33/48. It is now apparent that Don has the longer pipe.

Mark wants to fence 4 rectangular gardens, each with a length of 9 1/4 feet and a width of 4 1/2 feet. What is the total length

juin [17]

Answer:

110 feet

Step-by-step explanation:

Given that,

Length of the rectangular garden = 9 1/4 feet = 37/4 feet

Width of the rectangular garden = 4 1/2 feet = 9/4 feet

We need to find the total length of fencing Mark needs to surround all 4 gardens.

The length for 1 garden = perimeter of the garden

The length for 4 garden = 4×perimeter of the garden

= 4×2(l+b)

$=8(l+b)\\\\=8(\dfrac{37}{4}+\dfrac{9}{2})\\\\=8\times 13.75\\\\=110\ \text{feet}$

Hence, 110 feet is the total length of the fencing Mark needs to surround all 4 gardens.
