in the figure p is the incenter of isosceles rst what type of triangle is rpt? Thank you in advance .

Answers

Answer:

$\Delta \text{RPT is an isosceles triangle}$

Step-by-step explanation:

As in the triangle RST,

$RS=ST\ \ \ \Rightarrow m\angle SRT=m\angle STR$

Because if in a triangle two angles equal one another, then the sides opposite the equal angles also equal one another.

Incenter is obtained by the Intersection of a triangle's three angle bisectors and it is equidistant from the three sides of the triangle.

So, RP and TP are the angle bisectors of ∠R and ∠T respectively.

$\Rightarrow (m\angle SRT)/(2)=(m\angle STR)/(2)$

$\Rightarrow m\angle PRT=m\angle PTR$

$\Rightarrow PR=PT$

$\Rightarrow \Delta \text{RPT is an isosceles triangle}$

Isosceles triangles mean that 2 sides of the triangle are congruent. Since triangle RST is isosceles and P is its incenter, that means that PT and PR must be congruent, also. PRT is an isosceles triangle.

Jane,Andre,and Maria pick apples. Andre picks three times as many pounds Maria. Jane picks two times pounds as Andre. The total weight of apples is 840 pounds. How many pounds of apples does Andre pick?

Answers

Andre picked up almost 253 pounds of apples from a total of 840 pounds.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given are Jane, Andre, and Maria. All of them are picking apples such that Andre picks three times as many pounds as Maria. Jane picks two times pounds as Andre and the total weight of apples is 840 pounds

Assume that Maria took (x) pounds of apples.

Then, Andre will pick (3x) pounds of apples.

Finally, Jane will pick up (6x) pounds of apples.

The total weight of apples is 840 pounds.

Therefore, we can model the situation as follows -

x + 3x + 6x = 840

10x = 840

x = 84

So, Maria took 84 pounds of apples.

Now, the apples picked up by Andre = 3x = 3 x 84 = 252 pounds of apples

Therefore, Andre picked up almost 253 pounds of apples from a total of 840 pounds.

Andre picks 252 pounds of apples.

Further explanation:

Jane, Andre and Maria pick apples such that the apples picked by Jane are denoted by J, the apples picked by Andre are denoted by A and the apples picked by Maria are denoted by M.

The total weight of apples is 840 pounds.

Therefore, this can be written as,

${\text{J + A + M}} = 840$ ...... $(1)\n$

Andre picks three times as many pounds Maria then . ${\text{A=3M}}$ .

Jane picks two times pounds as Andre then . $J = 2A$ .

Substitute 3M for A in the equation $J = 2A$ to obtain relation between J and M as,

$\begin{aligned}{\text{J}}&={\text{2A}}\n&= {\text{2}}\cdot{\text{3M}}\n&={\text{6M}}\end{aligned}$

Now, substitute 3M for A and 6M for J in equation (1) then we get,

$\begin{aligned} {\text{6M + 3M + M} &= 840}\n{\text{10M}& = 840}\n{\text{M}& = 84}\n\end {aligned}$

Therefore, Maria picks 84 pounds of apples.

Substitute the obtained value of $M$ as 84 in equation $J = 2A$ as,

$\begin{gathered}{\text{J}}={\text{6}}\cdot {\text{84}}\n={\text{504}}\n\end{gathered}$

Therefore, Jane picks 504 pounds of apples.

Substitute the obtained value of $M$ as 84 in equation $J = 6M$ as,

$\begin{gathered}{\text{A}}={\text{3}}\cdot {\text{84}}\n={\text{252}}\n\end{gathered}$

Therefore, Andre picks 252 pounds of apples.

Thus, the total quantity that Andre picks is $\boxed{{252}\text{ } \text{pounds}}$ .
