B) 26 inches

C) 34 inches

D) 36 inches

Answer 1

c

Explanation:

Answer 2

Option C) 34 inches

Explanation:

We are given the following in the question:

The graph shows the number of beads on varying cord lengths.

The y-axis represents the number of beads and x-axis represents the cord length in inches.

The graph represents the equation:

`y = 2.52x + 1.61`

where y is the number of beads and x is the cord length.

We have to find the cord length of a necklace consisting of 88 beads.

Thus, we are given y = 88.

Putting this value in the equation, we get,

`y = 2.52x + 1.61\\88 = 2.52x + 1.61\\2.52x = 88 - 1.61\\2.52x = 86.39\\\\x = \displaystyle(86.39)/(2.52) = 34.28 \approx 34`

Thus, the cord length of necklace with 88 beads is approximatwly 34 inches.
