Answer:
78.5 ft²
Step-by-step explanation:
In this situation, the dog's 5 ft leash is the radius of the circle that he forms.
So, the radius is 5.
Use the area formula, A =
r². Plug in 5 as r, and 3.14 as 
A =
r²
A = (3.14)(5²)
A = (3.14)(25)
A = 78.5
So, the area of the grass he can cover is 78.5 ft²
Answer:
the solution for x will be given by {x| -13 < x < 13}
Therefore the correct option is B.
Step-by-step explanation:
i) given that |x| < 13
ii) therefore x < 13 for positive values of x
iii) for negative values of x we have -x < 13
therefore x > -13
iv) from ii) and iii) above we can conclude that the solution for x will be given by {x| -13 < x < 13}
Therefore the correct option is B.
Answer: 42
Step-by-step explanation:
Let the six consecutive even numbers be x , x+2 , x+4 ,x+6 ,x+8 ,x+10.
Then According to the question , we have

Now, the second number from the above six consecutive even numbers is x+2.
Substitute the value of x in it, we get
The second number in this sequence =
