Answer:
17.37
Step-by-step explanation:
y varies inversely as the square root of x
Mathematically:
y = k.root x
We first find k here
To find k, we were made to know that y is 21 and x = 361
k = y/root.x
k = 21/root. 361
k = 21/19
now what is y when x = 247
From y = k.root x
y = 21/19 * root 247
y= 21/19 * 15.72
y = 17.37
Answer:
Step-by-step explanation:
Product of b and 2 = 2b
According to the given description:
Answer:
x > 1 or x < 7
Step-by-step explanation:
| x - 4 | < 3
± ( x - 4 ) < 3
There are two possible cases
( x - 4 ) < 3 or - ( x - 4 ) < 3
x - 4 < 3 or - x + 4 < 3
x < 3 + 4 or 4 - 3 < x
x < 7 or 1 < x
x > 1 or x < 7
Therefore option 4 is correct.
