1.

The side of an equilateral triangle measures 17/2 cm. Find 1/4 of the perimeter of the triangle.Please answer step-by-step.

Answer»

All sides of an equilateral triangle are equal

PERIMETER of an equilateral triangle = 3 × LENGTH of sides

Perimeter = 3 × 17/2

Perimeter = 51/2 cm

1/4 of perimeter = 1/4 × 51/2

= 51/8cm = 6 3⁄8 cm

Answer» Given : - The vertices of the triangle are (2,1) , (3,7) & (8,4) Required to find : - Centroid of a triangle Concept used : - Before ! solving this question we need to know an important concept related to the centroid of a triangle . How to find the co-ordinates of the centroid of a triangle . Consider a traingle ABC such that the co-ordinates of the vertices of the triangle A = (X1,y1) , B = (x2,y2) & C = (X3,y3) . A centroid is a point where all the 3 ALTITUDES bisect each other . Since, the vertices of a triangle are 3 . so, the no. of altitudes are also 3 . A centroid divides the altitude of a triangle in the ratio of 1 : 2 . If we want to find the centroid of a triangle then we need to draw the corresponding altitudes . where all the 3 altitudes bisect that point is termed as the centroid . According to physics , it will be called as the centre of gravity . So, The formula to find the co-ordinates of centroid of a triangle is ; $\sf{ G = \left( \dfrac{ x_1 + x_2 + x_3}{ 3 } , \dfrac{ y_1 + y_2 + y_3 }{ 3} \right) }$ Here, G is the centroid of the traingle . USING this concept let's crack that question . Solution : - The vertices of the triangle are (2,1) , (3,7) & (8,4) . We need to find the co-ordinates of the centroid . So, Let the vertices of the traingle be ; A = (2,1) B = (3,7) C = (8,4) This implies ; x1 = 2 , y1 = 1 x2 = 3 , y2 = 7 x3 = 8 , y3 = 4 Now, Using the formula let's find the co-ordinates of the centroid . $\sf{ G = \left( \dfrac{ x_1 + x_2 + x_3}{ 3 } , \dfrac{ y_1 + y_2 + y_3 }{ 3} \right) }$ Substituting the values in it $\sf \longrightarrow G =\left( \dfrac{ 2 + 3 + 8}{3} , \dfrac{1 + 7 + 4}{3} \right) \\ \\ \sf \longrightarrow G = \left( \dfrac{13}{3} , \dfrac{12}{3}\right) \\ \\ \sf \longrightarrow G = \left( \dfrac{13}{3} , 4 \right) \\ \\ \\ \therefore \tt Co-ordinates \; of \; the \; centroid = \left( \dfrac{13}{3} , 4 \right)$

Find the centroid of triangle if vertices are (2,1) (3,7)( 8,4 )

Answer»

Given : -

The vertices of the triangle are (2,1) , (3,7) & (8,4)

Required to find : -

Centroid of a triangle

Concept used : -

Before ! solving this question we need to know an important concept related to the centroid of a triangle .

How to find the co-ordinates of the centroid of a triangle .

Consider a traingle ABC such that the co-ordinates of the vertices of the triangle A = (X1,y1) , B = (x2,y2) & C = (X3,y3) .

A centroid is a point where all the 3 ALTITUDES bisect each other .

Since, the vertices of a triangle are 3 . so, the no. of altitudes are also 3 .

A centroid divides the altitude of a triangle in the ratio of 1 : 2 .

If we want to find the centroid of a triangle then we need to draw the corresponding altitudes . where all the 3 altitudes bisect that point is termed as the centroid .

According to physics , it will be called as the centre of gravity .

So,

The formula to find the co-ordinates of centroid of a triangle is ;

$\sf{ G = \left( \dfrac{ x_1 + x_2 + x_3}{ 3 } , \dfrac{ y_1 + y_2 + y_3 }{ 3} \right) }$

Here, G is the centroid of the traingle .

USING this concept let's crack that question .

Solution : -

The vertices of the triangle are (2,1) , (3,7) & (8,4) .

We need to find the co-ordinates of the centroid .

So,

Let the vertices of the traingle be ;

A = (2,1)

B = (3,7)

C = (8,4)

This implies ;

x1 = 2 , y1 = 1

x2 = 3 , y2 = 7

x3 = 8 , y3 = 4

Now,

Using the formula let's find the co-ordinates of the centroid .

$\sf{ G = \left( \dfrac{ x_1 + x_2 + x_3}{ 3 } , \dfrac{ y_1 + y_2 + y_3 }{ 3} \right) }$

Substituting the values in it

$\sf \longrightarrow G =\left( \dfrac{ 2 + 3 + 8}{3} , \dfrac{1 + 7 + 4}{3} \right) \\ \\ \sf \longrightarrow G = \left( \dfrac{13}{3} , \dfrac{12}{3}\right) \\ \\ \sf \longrightarrow G = \left( \dfrac{13}{3} , 4 \right) \\ \\ \\ \therefore \tt Co-ordinates \; of \; the \; centroid = \left( \dfrac{13}{3} , 4 \right)$

A dealer earned a profit of 5% by selling a radio for 714. Find the cost price oHis father's present age = (3x12) yearsEXAMPLE 8.the radio.SolutionLet the cost nrice of the radio her

Answer»

Answer:

CP = 680

Step-by-step explanation:

SP of RADIO = 714

Profit % = 5%

LET CP be 'x'.

∴ profit = 5x/100

P = SP - CP

5x/100 = 714 - x

5x/100 + x = 714

105x/100 = 714

x = 714*100/105

x = 680

∴ CP = 680

A man leaves ₹185378 to be divided between his son and daughter in the ratio 5 whole 2/3 : 2 whole 1/5. Find the amount each receives.

Answer»

GIVEN: Ratio of AMOUNT divided between SON and daughter

$= 5\frac{2}{3} : 2\frac{1}{5}$

$= \frac{17}{3} : \frac{11}{5} =85:33$

Let the share of amount of son and daughter be 85x and 33x

Then 85x + 33x= Rs 185378

$→118x =Rs \: \: 185378$

$→<klux>X</klux> =Rs \: \frac{185378}{118} =Rs \: \: 1571$

Hence amount received by son = 85 x Rs 1571 Rs = 133535

and amount received by daughter = 33 x Rs 1571 = Rs 51843

.therefore,intrest=p*r*t/100

so, =2400*7/2*8/12/100

=24*7*8/2*12
