Shown below is a blueprint for a rectangular kennel at a pet hotel.

yulyashka [42]

Answer:

The total length of fencing needed to enclose the kennel 74 feet.

Step-by-step explanation:

Given:

The blueprint of the rectangular kennel shows one side is 23 feet and another side is 14 feet.

As it is a rectangular shape, let the two sides be the length and the breadth of the rectangular kennel. i.e

$length = L = 23\ feet\\breadth = B = 14\ feet\\$

To find:

Total length of fencing needed is to enclose the kennel. i.e

Perimeter of a rectangular kennel = ?

Solution:

we have the formula for perimeter of a rectangle as giving below.

$\textrm{perimeter of rectangle} = 2(length + breadth) \\\textrm{total length of fencing} = 2( L+B)\\ \textrm{substituting the values of length and breadth we get}\\ \textrm{total length of fencing} = 2(23+14)\\=2\times37\\= 74\ feet$

Therefore,the total length of fencing needed to enclose the kennel 74 feet.

Find the product, using suitable properties:

Ray Of Light [21]

Answer: a) 6700 b) 2233

Step-by-step explanation:

a)

$(-67)*(-99)+(-67)*(-1)=\\(-67)*((-99)+(-1))=\\(-67)*(-100)=\\6700$

b)

$29*(80-3)=\\(30-1)*(80-3)=\\30*80+(-1)*80+(-3)*30+(-1)*(-3)=\\2400-80-90+3=\\2403-170=\\2233$

In the United States, among a representative group of 6,006 white men and 1,126 black men, ages 70-79 at diagnosis with stage IV

Ivenika [448]

Answer:

White men diagnosed with stage IV prostatic adenocarcinoma within the age bracket of 70-79 are 1.27 times more likely to survive five years after the diagnosis of stage IV prostatic adenocarcinoma than black men.

Step-by-step explanation:

The exposure is race and the outcome is survival.

Race Alive Dead T

W 2337 3669 6006

B 344 782 1126

Relative Risk - 1.27

White men diagnosed with stage IV prostatic adenocarcinoma within the age bracket of 70-79 are 1.27 times more likely to survive five years after the diagnosis of stage IV prostatic adenocarcinoma than black men.

Find the Highest Common Factor (HCF) of 196 and 12

Norma-Jean [14]

Answer:

The greatest common factor is 4

Step-by-step explanation:

1.Find the prime factorization of 12

a) 12 = 2 × 2 × 3

2.Find the prime factorization of 196

a) 196 = 2 × 2 × 7 × 7

To find the GCF, multiply all the prime factors common to both numbers:

a)GCF=2x2

Therefore, GCF = 2 × 2

GCF = 4
