Give an example of this when adding two rationalnumbers with different signs and provide the product.
kolezko [41]

ANSWER:

\begin{gathered} \frac{4}{5}+-\frac{8}{3}=-\frac{28}{15} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{32}{15} \end{gathered}

STEP-BY-STEP EXPLANATION:

Rational numbers are all numbers that can be expressed as a fraction, that is, as the quotient of two whole numbers.

Therefore, an example would be:

\begin{gathered} \frac{4}{5}\text{ and - }\frac{8}{3} \\ \text{adding} \\ \frac{4}{5}+-\frac{8}{3}=\frac{4}{5}-\frac{8}{3} \\ \frac{4}{5}-\frac{8}{3}=\frac{4\cdot3-5\cdot8}{5\cdot3}=\frac{12-40}{15}=-\frac{28}{15} \\ \text{ product} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{4\cdot8}{5\cdot3}=-\frac{32}{15} \end{gathered}

Find the volume of a prism with triangular bases where the perimeter of the base = 16", apothem = x", and the prism height = 10"
DIA [1.3K]
First, calculate for the area of the base by the equation given,
                                              A = 1/2aP
where A is area, a is apothem, and P is perimeter. Substituting the known values,
                                              A = 1/2(x)(16") = 8x in²
Next, solve for the volume of the prism by the equation,
                                                V = Bh = (8x in²)(10 in)
                                                   V = 80x in³
Thus, the volume of the prism is approximately 80x in³.
