Answer:

Length = 10.435 inches

Step-by-step explanation:

Let the length be l

Let the width be w

Since the length is 9 inches more than half the width.

Then;

L = 0.5w + 9

Perimeter of a rectangle is;

P = 2Lw

Thus;

P = 2w(0.5w + 9)

Since perimeter = 60

Then;

2w(0.5w + 9) = 60

w² + 18w = 60

w² + 18w - 60 = 0

From quadratic formula;

w ≈ 2.87 in

L = 0.5(2.87) + 9

L = 10.435 in

The approximate volume in milliliters, y, for a volume of x fluid ounces is equal to 29.57 times the value of x. Which table rep
Angelina_Jolie [31]

The table which represents the relationship is:

Fluid ounces, x            Volume y ( in millimeters)

       1                                       29.57

       2                                      59.14

       3                                      88.71

       4                                     188.28

In mathematics, a relation describes how two distinct sets of information related to one another. If more than two non-empty sets are taken into consideration, a connection between their elements will indicate that more than two sets are being evaluated.

Let y be the volume of fluid x in millimeters.

Now, y is equal to 29.57 times the value of x.

Therefore,

y = 29.57 × x

y = 29.75x

So, when x = 1:

y = 29.75(1) = 29.57

When x = 2,

y = 29.57(2) = 59.14

When x = 3,

y = 29.57(3) = 88.71

When x = 4,

y = 29.57(4) = 118.28

Therefore, the table that represents the relationship is:

Fluid ounces, x            Volume y ( in millimeters)

       1                                       29.57

       2                                      59.14

       3                                      88.71

       4                                     188.28
