The correct answer to this question is this one:

geometric means you multiply by some factor to get the next number
you start at 18
the next number is 18*K (K is the factor)
the 3rd number is 18*k*k

but we know the third number is 8

So <span>x = 12.</span>

Answer: The length of the second arc is 12 feet.

Step-by-step explanation:

Since we know that

A rope is swinging in such a way that the length of the arc is decreasing geometrically,

Length of first arc = 18 feet

Length of third arc = 8 feet

Let the length of second arc be x

As we know that

\frac{a_2}{a_1}=\frac{a_3}{a_2}\\\\\frac{x}{18}=\frac{8}{x}\\\\x^2=18\times 8\\\\x^2=144\\\\x=\sqrt{144}\\\\x=12

Hence, the length of the second arc is 12 feet.

worty [1.4K]

Answer: 1/5 of the total distance to his grandmothers house was traveled on Sunday

Step-by-step explanation:

The total distance to to his grandmothers house is assumed to be 1

Marks family traveled 7/10 of the distance to his grandmothers house on Saturday. The remaining distance would

1 - 7/10 = 3 /10

They traveled 2/3 of the remaining distance on Sunday. This means that the distance that they travelled on Sunday is

2/3 × 3/10 = 2/10 = 1/5
