In City Lake, researchers caught, marked, and released 258 bass. Later, they took a sample of 130 bass and found that 26 were ma

Vsevolod [243]

26 out of 130 were marked.

Divide 26 by 130:

26/130 = 0.20

20% of the bass caught were tagged.

Now divide the total amount caught and tagged by that percentage:

258 / 0.20 = 1,290

There are 1,290 bass in the lake.

Suppose a rectangular garden plot has a length that can be expressed as x+2 feet and a width expressed as x+7 feet. Write a poly

mafiozo [28]

Answer:

$Area = x^2 + 9x + 14$

$Perimeter = 4x + 18$

Step-by-step explanation:

Given:

Length of rectangular garden = (x + 2) ft

Width = (x + 7) ft

Required:

a. Polynomial expression of the area of the garden

b. Polynomial expression of the perimeter of the garden

SOLUTION:

Area of the rectangular garden = length × width

$Area = (x + 2)(x + 7)$

Expand using the distributive property of multiplication

$Area = x(x + 7) +2(x + 7)$

$Area = x^2 + 7x + 2x + 14$

$Area = x^2 + 9x + 14$

Perimeter = 2(length) + 2(width)

$Perimeter = 2(x + 2) + 2(x + 7)$

$Perimeter = 2x + 4 + 2x + 14$

Collect like terms

$Perimeter = 2x + 2x + 4 + 14$

$Perimeter = 4x + 18$

777dan777 [17]

D

19/50 multiply 2 on numerator and denominator it becomes 38/100
38/100 = 0.38 since 38/100 is 38 divide by 100 which is 0.38
