Answer:
1/8
Step-by-step explanation:
2^(-3) = (1/2)^3 = 1/2^3 = 1/8

x = 6
given + =
to eliminate the fractions multiply through by the lowest common multiple of x, 3 and 6 , that is 6x
multiply all terms by 6x gives
18 + 2x = 5x ( subtract 2x from both sides )
18 = 3x ( divide both sides by 3 )
6 = x
As a check
+ = + =
Answer: B. 254.34 cm^2
Step-by-step explanation:
The area of a circle is pi times the radius squared.
Using the diameter we have to find the radius.
The diameter is two times the radius meaning that the radius is half the diameter.
18/ 2 = 9
The radius will be 9 cm
Now using the formula v= pi * r^2 , input the value for pie and the radius and solve for v the volume
v = 3.14 * 9^2
v= 3.14 * 81
v = 254.34 cm^2
Answer:
b^7/5
Step-by-step explanation:
The 5 is in front of the radical ,so it would go on the denominator.
