Answer:
Rational
Step-by-step explanation:
Any number that can be represented as a fraction is rational. 13.654 can be represented as the mixed number 13 and 654/1000, making it a rational number.
For this case we have the following expression:
We clear the value of the variable "g", for this:
We multiply by 4 on both sides of the equation:
We divide by 3 on both sides of the equation:
We simplify:
Answer:
Answer:
55.95 ft²
Step-by-step explanation:
Circumference formula: C = 2πr => r = C / (2π)
Area formula: A = πr²
Substituting C / (2π) for r in the above equation, we get:
C 47 ft
A = π( ----------- )² = π ( -------------- )²
2π (2π)
or ...
π(47 ft)² 2209 ft²
A = ---------------------- = -------------------- = 55.95 ft²
4π² 4(3.14159)²
X=15
expand the brackets and collect like terms so 6x+15=7x
then -6x to get x=15
