Answer:
2, 4
Step-by-step explanation:
Let there are two unknown consecutive pairs of even integers 2n and 2n+2.
If the sum of the reciprocals of those two integers is 3/4, then we can write,
1/2n +1/(2n+2) =3/4 ...... (1)
Solving this above equation we can check whether the integers exist or not.
Now, from equation (1) we get,
1/n +1/(n+1) =3/2
⇒
⇒4n +2 =3n²+3n
⇒3n²-n-2 =0
⇒ (n-1)(3n+2) =0
⇒ (n-1) =0 {Since if (3n+2) =0 then, n will be a negative fraction, which is not possible}
⇒ n=1
∴ 2n =2 and 2n+2 =4
Hence, the two integers are 2, 4. (Answer)
Answer:
9, if you round to 2 Decimal Places.
(C = 18π = 18 × π = 56.54 (2 DP))
r = C ÷ 2π
= 56.54 ÷ 2 × π ≈ 9
For this case we have that by definition the time is given by:
Where the variable "d" represents the distance and "v" represents the speed.
So, first we need to know the total distance:
Then, the time for 75mph is given by:
Answer:
6,4 hours
Answer:
(1,2)
Step-by-step explanation:
x value -2+4 /2 = 1
y value -2+6/2 = 2
we are ratio as
It will be equivalent to only those terms which would be multiple of this term
so, we will multiply top and bottom term by 5
and we get
so, it is very similar to 12/35
so, it will be equivalent to 12/35
so, option-C.......Answer
