Use the surface area formula of a rectangular prism to find the width. (I have changed it to use the same terms given in the problem).

(

)

Because of the given information, it is known that:

208

The width is not know, so let it keep it's variable

. But substitute the other values into the equation:

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 $\frac{1}{12}$

If a = 4 ft, c = 13 ft, and m∠B = 17°, what is the approximate area of ABC?

andre [41]

Answer:

7.6 ft² ( to 1 dec. place )

Step-by-step explanation:

given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula

A = $\frac{1}{2}$ ac sin B

= 0.5 × 4 × 13 × sin 17° ≈ 7.6
