Find the length of AB, given that be is a median of the triangle and AC = 30.
RSB [31]

SOLUTION

Draw the diagram

a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.

Hence

|DB|\text{ bisect |AC|}

SInce AC=30, Then

\begin{gathered} AB=15,\text{ CB= 15} \\ \text{Hence} \\ |AB|=15 \end{gathered}

Thus, from the median properties of a triangle, AB = 15

Apply the product rules to determine the sign of each expression
sammy [17]

Answer:

Step-by-step explanation:

1). (\frac{-4}{9})\times (\frac{7}{4})=(-1)(\frac{4}{9})(\frac{7}{4} )

                =-\frac{7}{9} [Negative]

2). (-2\frac{3}{4})(-1\frac{1}{5})=(-1)(2\frac{3}{4})(-1)(1\frac{1}{5})

                        =(-1)^2(2\frac{3}{4})(1\frac{1}{5})

                        =(2\frac{3}{4})(1\frac{1}{5}) [Positive]

3). (3)(-3)(-3)(-3)(-3) = 3.(-1).3.(-1).3.(-1).3(-1).(3)

                              = (-1)⁴(3)⁵

                              = (3)⁵ [Positive]

4). (-\frac{1}{6})(-2)(-\frac{3}{5})(-9) = (-1)(\frac{1}{6})(-1)(2)(-1)(\frac{3}{5})(-1)(9)

                                   = (-1)^4(\frac{1}{6})(2)(\frac{3}{5})(9)

                                   = (\frac{1}{6})(2)(\frac{3}{5})(9) [Positive]

5). (-\frac{4}{7})(-\frac{3}{5})(-9)=(-1)(\frac{4}{7})(-1)(\frac{3}{5})(-1)(9)

                            =(-1)^3(\frac{4}{7})(\frac{3}{5})(9)

                            =-(\frac{4}{7})(\frac{3}{5})(9) [Negative]

6). (-\frac{10}{7})(\frac{8}{3})=(-1)(\frac{10}{7})(\frac{8}{3})

                    =-(\frac{10}{7})(\frac{8}{3}) [Negative]

Mr. Hinckley owns 83 acres of land, he divides the land into eight equal sections to sell to eight buyers which phrase describes
anygoal [31]

Alright, lets get started.

Mr. Hinckley owns 83 acres of total land.

He divides the land into eight equal sections to sell to eight buyers.

It means, we could find the land each buyer receives by dividing total land by 8.

So, each buyer receives land = \frac{83}{8}

So, each buyer receives land = 10.375 acres

So, the answer is 10.375 acres lands received by each buyer. : Answer

Hope it will help :)
