a regular pentagon has an apothem of 7.43 cm. Find the length of a side of the pentagon and the length of the radius of the circ
Neko [114]
You have to figure it out.  First, the sum of the angles in a polygon = n-2(180) where n is the number of sides.  For a pentagon, this is 5-2(180)=540.  then divide by 5 for each of 5 large angles in the pentagon, and then divide by 2 for the angle formed by the radius in the right angle.  This is 540/5=108 divided by 2 = 54 degrees in the right angle.  Now that you know the angle , then use trig to solve the problem...

Solve each equation by graphing. Round to the nearest tenth.
arlik [135]

B

rearrange into standard form : ax² + bx + c = 0 (a≠ 0)

2x² - 3x - 2 = 0

(x - 2)(2x + 1) = 0 ( equate each factor to zero and solve for x )

x - 2 = 0 ⇒ x = 2

2x + 1 = 0 ⇒ x = - 0.5

Gisselle has 1/2 of a candy bar. She role off 1/2 of what she had. She then took the piece she broke off and split it into three
saul85 [17]

Answer:

\frac{1}{12}

Step-by-step explanation:

Given:

Gisselle has 1/2 of a candy bar.

She role off 1/2 of what she had and split it into three equal pieces.

Question asked:

What fraction of a candy bar was each piece?

Solution:

Gisselle has = \frac{1}{2} \ of \ a \ candy \ bar

She role off = \frac{1}{2} \ of \ what\ she \ had

                     =\frac{1}{2}  \ of\  \frac{1}{2}\\=\frac{1}{2} \times \frac{1}{2}\\\\=\frac{1}{4}

As she split it into three equal pieces, we will divided it by 3, we get,

\frac{1}{4} \div3\\\frac{1}{4}\times\frac{1}{3}

\frac{1}{12}

Therefore, fraction of a candy bar of each piece is \frac{1}{12}
