Answer:
x = 9
Step-by-step explanation:
divide both sides of the equation by 4 to isolate the x variable according to algerba. Hope it helps!
Answer:
r = 3/2
Step-by-step explanation:
ratio (r) is the number that, when multiplied by the previous (n-1) term, gives the nth term of the geometric sequence (). To find the common ratio, we can take any term and divide it by its preceding term (rearrange the formula to get ). If we take 24 and divide it by 16, we get the common ratio of 3/2 (, ).
That's a 240 degree sector of a 9 inch radius circle. The whole circle has area πr² and we want 240/360 of it.
A = (240/360) π (9²) = 54 π
Answer: 54 π square inches
That's the exact answer. An approximation is
169.646 square inches
Answer:
Step-by-step explanation:
72 = 2 * length + 2 * width
(72 -2*width)/2 = length
36-width = length
we need to know something else about the rectangle
Step-by-step explanation:
Rewrite the formula so that the term with t is positive on the left hand side.
Isolate the term, then step by step, isolate the variable you want as the subject.
p+prt=a
prt=a−p get rid of +p by -p
prt=a−p get rid of x pr by ÷ pr
t=a−ppr
