Ragan makes beaded jewelry. The graph below shows the number of beads on varying cord lengths.
MakcuM [25]

Answer:

Option C) 34 inches

Step-by-step 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\frac{86.39}{2.52} = 34.28 \approx 34

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

The expression that shows the total gallons is 0.5gallon/1 day*16cups/1gallon * 7days/1week

<h3>Dimensional Analysis</h3>

From the given question, we are told that Katrina drinks 0.5 gallons per day. In order to determine the total cup that she drank in a a week, we will have:

Total gallons in a week. = 0.5gallons/1 day * 7days/1

Total gallons in a week = 3.5 gallons

Since 1 gallon. = 16 cups, then;

3.5 gallons = 16cups/1gallon * 3.5gallons

3.5 gallons = 56 cups

Hence the expression that shows the total gallons is 0.5gallon/1 day*16cups/1gallon * 7days/1week
