change the units to yards

21/3 = 7 yds

12/3 = 4 yds

A= 7*4 = 28 yds

cost = 29.56 * 28 = 827.68

the total cost is $827.68

PLEASE HELP
sweet-ann [11.9K]

Answer:

m < ANM = 36 degrees.

AM = 9.40 cm to the nearest hundredth.

Perimeter =  94.05 cm to the nearest hundredth.

Step-by-step explanation:

As we have a regular pentagon:

m < ANB = 360 / 5

= 72 degrees

So m < ANM = 1/2 * 72

= 36 degrees.

In the triangle ANM, AN = 16 so

sin 36 = Am / 16

AM =  16 sin36

= 9.4045 cm.

AB = 2 * AM = 18.809 cm

So as all sides are equal:

Perimeter = 5 * 18.809

= 94.05 cm.

M is -7/2 and b is 0

The m is the rate of change and it is always the coefficient of the X. The b is the constant in the equation and in this case there is none so it is 0.
