Using x as the variable, write a formula to find the perimeter of the figure. Use the formula to find the perimeter. a regular d

Mamont248 [21]

Answer:

c. 12x; 111 cm

Step-by-step explanation:

The regular dodecagon has 12 sides. Each side has a length of x=9.25 cm, and we know that the perimeter of the figure is the sum of the lengths of all the sides: Therefore, since we have 12 sides, the perimeter will be given by the product between the length of each side, x, and the number of sides, 12:

$p=12 \cdot x$

and if we substitute x = 9.25 cm, we find

$p=12 \cdot 9.25 cm=111 cm$

HELP for (ii)…..how do we find a?

Mariana [72]

By using the information given on the graph, we can see that a = 3.

<h3>How to find the value of a?</h3>

Here we have an exponential of the form:

$y = p*a^x$

And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:

$4 = p*a^0\\\\36 = p*a^2$

From the first equation we get that p = 4, replacing that on the second one we get:

$36 = 4*a^2\\\\36/4 = 9 = a^2\\\\\sqrt{9} = 3 = a$

So we conclude that a = 3.

If twelve pounds of nails cost $3.84 what is the unit cost A) 32c B) 28c C) 23c D) 18c

aalyn [17]

Answer:

Option A) 32c

Step-by-step explanation:

we know that

To find the unit cost, divide the total cost of twelve pounds by twelve pounds

so

$\frac{\$3.84}{12}=\$0.32$

Remember that

1$=100 cents

Convert dollars to cents

$\$0.32=0.32*100=32c$

therefore

The cost of one pound of nails cost 32 cents
