For this case we have that by definition, the circumference of a circle is given by:
Where:
d: Is the diameter of the circumference
According to the data we have to:
Substituting:
Rounding out we have that the diameter is: 80
Answer:
Option B
It would be "Nine times parentheses eight plus four"
If it has been marked up 40% then you now have 140%. To find 140% of $63 you need to multiply 63 by 1.4 to give $88.20. So the mark up is $25.20
I can only assume that you meant, "Solve for x:"
Apply the exponent 3/2 to both sides of this equation. The result will be
3/2
343 = x/6.
Multiplying both sides by 6 isolates x:
3/2
6*343 = x Since 7^3 = 343, the expression for x
can be rewritten as
3/2
6*(7^3) = x which can be further simplified, as follows:
x = 6^(3/2)*7^(9/2), or:
x = 6^(3/2)*7^(8/2)*√7, or
x = 6^(3/2)*7^4*√7
