For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:
Where "r" represents the radius of the circle, in this case
Substituting in the perimeter equation we have:
Rationalizing we have:
Taking out common factor :
Answer:
Option C
Answer:
72 Keychains
Step-by-step explanation:
120 feet = $3.25
divide 120 by 3.25 to find how much string can be bought with $1. The result is 36.923. Then multiply that number by the number of dollars allotted to buying string. 8*36.923= 295.384. This is the total number of feet of string they have. They use 1 foot for each key chain so they can make 295 keychains based on how much string they have.
35 beads = $2.59
Divide 35 by 2.59 to find how many beads can be bought with $1. The result is 13.514. Then multiply that number by the number of dollars allotted to buying beads. This comes out to 364.878. This means She can buy 364 beads. Each Key chain needs 5 beads so divide 364/5 getting a total of 72 keychains.
Since there aren't enough beads to make any more than 72 keychains, they can make a total of 72 keychains (even though there is extra string)
Answer:
22 divided by 300 will be equal to 0.07333.
Step-by-step explanation:
Dividing 22 by 300
The value of
So, the value of 22 divided by 300 will be equal to 0.07333.
Step-by-step explanation:
<em>Vamsi is X years old</em>
Vamsi = X
<em>his brother is 3 years elder to him</em>
Brother = X + 3
<em>his uncle is 4 times his age</em>
Uncle = 4X
<em>his aunt is 5 years younger than his uncle</em>
Aunt = Uncle - 5
<em>what will be the age of his uncle 6 years from now</em>
= 4X + 6
<em>what are the ages of vamis brother, uncle and aunt?</em>
Assume Vamis = 15 years
Brother = X + 3 = 15 + 3 = 18
Uncle = 4X = 4 * 15 = 60
Aunt = Uncle - 5 = 60 - 5 = 55
<em>what will be the age of his uncle 6 years from now</em>
Uncle = 4X + 6 = 60 + 6 = 66
