Assuming that the base of the prism is a regular pentagon, the area of a regular polygon is given by the formula A = 0.5pa; where p is the perimeter and a is the apothem. An apothem is a line that connects the center of the polygon to the midpoint of a side and is also perpendicular to the said side. For this example, the assumed apothem here is k.

Area of base = 2 (0.5 x 20" x k) = 20k

The sides of the prism are rectangles, with width 6" and length (20"/5) = 4".
Area of sides of prism = 5 (6" x 4") = 120

Total Area T.A. = 120 + 20k

Area of base = 2 (0.5 x 20" x k) = 20k

The sides of the prism are rectangles, with width 6" and length (20"/5) = 4".

Area of sides of prism = 5 (6" x 4") = 120

Total Area T.A. = (120 + 20k)

This is correct because I did this question and got it right.

Dahasolnce [82]
If Rita has driven 30 miles so far (three-fifths of the way home), you can calculate what is the total length of her drive using the following steps:

x ... total length
three-fifths of the way home = 30 miles
3/5 of x = 30 miles
3/5 * x = 30    /*5/3
x = 30 * 5/3
x = 50 miles

The total length of her drive is 50 miles.

Verdadero o falso a) al reducir a comun denominador las fracciones se sustituyen por otras equivalentes
alexgriva [62]

Answer:

Verdadero

Step-by-step explanation:

Verdadero, cuando cambias dos fracciones para darles un denominador comun la fraccion entera se sustituye para otra que tiene el mismo valor numerico que la original. Por ejemplo tenemos una fraccion 2/6 en la cual tenemos que cambiarle el denominador a uno comun con otra fraccion que es 18. Entonces sustituyemos la fraccion por la siguente fraccion 6/18. Esta nueva fraccion es equivalente a la original y los dos tienen el mismo valor numerico...

2 / 6 = 0.333

6 / 18 = 0.333

Answer:

6.04 kilometers

Step-by-step explanation:

First, by AA triangle similarity theorem, we know that the two triangles are equal.

So, we can set up a ratio

3,500/2000=4200/x

cross multiplying, we get

3500x=4200*2000

and simplifying, we get x=2400

the distance will be 2,400+4,200=6600 yards

converting to kilometers,

6600*0.0009144=6.04
