Find the area of the regular pentagon. 4.1 cm 6 cm Area = [?] cm? Enter your answer to the nearest tenth.

Assoli18 [71]

Answer:

Area of the given regular pentagon is 61.5 cm².

Step-by-step explanation:

Area of a regular polygon is given by,

Area = $\frac{1}{2}aP$

Here, a = Apothem of the polygon

P = Perimeter of the polygon

Apothem of the regular pentagon given as 4.1 cm.

Side of the pentagon = 6 cm

Perimeter of the pentagon = 5(6)

= 30 cm

Substituting these values in the formula,

Area = $\frac{1}{2}(4.1)(30)$

= 61.5 cm²

Therefore, area of the given regular pentagon is 61.5 cm².

At the gift shop, they sell small greeting cards and large greeting cards. The cost of a small greeting card is $1.60 and the co

erik [133]

<h2>Explanations:</h2>

From the given question, we have the following parameters

Cost of a small greeting card = $1.60

The cost of a large greeting card = $4.05.

Cost of 5 small greeting cards = 5(1.60)

Cost of 5 small greeting cards = $8.00

Cost of 4 large greeting cards = 4(4.05)

Cost of 4 large greeting cards = $16.2

Cost of 5 small and 4 large = $8.00 + $16.2

Cost of 5 small and 4 large $24.2

Hence it would cost $24.2 to get 5 small greeting cards and 4 large greeting cards

Similarly;

Cost of x small greeting cards = 1.60x

Cost of y large greeting cards = 4.05y

Cost of small greeting cards and y large greeting cards = 1.60x + 4.05y

Hence it would cost $(1.60x + 4.05y) to get x small greeting cards and y large greeting cards

Which of the following is fartherest to the left on a number line 1/5, (0.1)to second power, 0.02

Alexxx [7]

1/5 is .2
.1^2 is .01
.02 is .02

So the furthest left would be the smallest number, which in this case is 0.1^2

Can someone please HELP me on how to do this

frutty [35]

Answer:

4)x= g-c

5)x =u+k

6)x = g-c

7) $a=\frac{k}{u}$

8) $x= \frac{g}{c}$

9) $a=\frac{4}{12m}$

10) $x= \frac{2c+3}{3}$

11) $a=\frac{n+p}{m}$

12) $a= \frac{ub}{k}$

13)a= d -r + c

14) $x=\frac{np}{m}$

Step-by-step explanation:

4) g= c+x

x= g-c

5) u=x-k

x =u+k

6)g = c+x

x = g-c

7) $u=\frac{k}{a} \\\\a=\frac{k}{u}$

8) g=xc

$x= \frac{g}{c}$

9) 12am = 4

$a=\frac{4}{12m}$

10)-3x+2c = -3

2c = -3 +3x

2c +3 = 3x

$x= \frac{2c+3}{3}$

11) am= n+p

$a=\frac{n+p}{m}$

12) $u = \frac{ak}{b} \\\\u*b = ak\\\\a= \frac{ub}{k}$

13)a-c = d-r

a= d -r + c

14)xm= np

$x=\frac{np}{m}$
