Given:A(0,0) & B(8,-5)

Mid point (x,y)=(x1+x2)/2 , (y1+y2)/2

=(0+8)/2 , (0+-5)/2

=(4, -5/2)

8y+5x=0 is a right answer

Part 1

Part 2

Part 3

Part 4

Let A(x,y)B(1,4)Centre=(2,-3)

2=x+1/2x+1=4x=3

-3=y+4/2-6=y+4y=-6-4=-10

A(3,-10)

4s² - 4s + 1

(2s)² - 2 ×2s × 1 + 1²

(2s - 1)² = 0

So, s = 1/2

The correct answer is x=67°

From exterior angle property ,

123° = 56° + x => x = 123°-56° = 67°

French maid modern colonies and houses according to their modern infrastructure and architecture in Vietnam they prepared a very well and occupied sewage system so that they are civil system is proper according to their modernity but on the opposite side of their for Friends Colony is there Hue Vietnam is poor people who are deciding the rest of the appropriate place in the sewage pipes so that the rats in the modern society were most common

The diameter of new planet is 74162.7907 m

74162.7907 m is the following question answer.

new planet diameter is 74162.7907 is the correct answer of the following question

initially total = 630boys:girls=3:2boys=378girls=252

now after admission of 90 total=630+90=720boys:girls=7:5so boys=420so girls=300so newly admitted boys=420-378=42

5x-3y+2=0; we get (7,-2); 5(7)-3(-2)+2=0, 35+6+2=47(xx), 5x-3y+2=0; we get (6,3), 5(6)-3(3)+2=30-9+2=0; 32-9=24= ok

the right answer is -4

coordinate of mid point (x,y)x = (x1 +x2)/2y =(y1 +y2)/2A/qx =(-5 + (-1))/2 = -3⇒a/3 = -3⇒a =-9y = (4+0)/2 = 2coordinate of mid point = (-3,2)so,a= -9

please like the solution 👍 ✔️

Given P is midpoint of QR

so, P = ((-5-1)/2 , (4+0)/2)

P = ( -3, 2)

So, given P = (a/3 , 2)

Comparing gives us

a/3 = -3

a = -9

please explain briefly i couldnot understand it

bhai ye kya likha h i could not read it

option 4) 0.56 and 0.57

Let A be the point on the x-axis

so, let A=(a,0) , B=(-5,-2) and C=(4,-2)

Now, let D be the mid point of BC

According to ur question

A lies on the perpendicular bisector of the line joining B(-5,-2) and C(4,-2)That means, AD is perpendicular to BC and also bisects BC

which means the triangle is isocelous

Thus, use AB = AC=> (a + 5)^2+ 4 = (a - 4)^2+ 4

=> (a + 5)^2- (a - 4)^2=0

=> (a + 5 + a - 4)(a + 5 - a +4) = 0

=> (2a + 1)(9) = 0

=> a = -1/2

number of boys and girls are 9+5=14

14 is the best answer

let the no. of boys=9xno. of girls=5xA.T.Q9x+5x=22414x=224x=224/14x=16no of boys=9*16=144no. of girls=5*16=80

number of boys and girls are 9+5=14

14 is the best answer

letthe no. of boy and girl be xthen, 9x+5x=224. (given)14x=224x=224/14x=16

9x=9*16=114 boys5x=5*16=80

14x=2249x=224/14×9=1445x=5×16=80

sukriya

Total number of students = 900

Number of girls = (30/100)*900= 30*9= 270

Therefore, Number of girls are 270

greater no. lie on the right of the smaller no. on number line-11<10so 10 lies right to -11 on number line

A press releaseis a written communication that reports specific but brief information about an event, circumstance, or other happening. It's typically tied to a business or organization and provided tomediathrough a variety of means.

√3.1428=1.772√0.31428=0.560

We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places.

I want method for this sums

For collinear points, area of triangle=0(1/2)[7(1-k)+5(k+2)+3(-2-1)]=0(1/2)[7-7k+5k+10-9]=0(1/2)[8-2k]=02k=8k=4

Total Number of Families (N) = 10,000a) Number of families which buy Newspaper A = 40%*N +5%N + 4%N +2%N = 40/100*10000 + 5/100*10000 + 4*100*10000 + 2/100*10000 = 10000/100(40+5+4+2) = 100(51) = 5100

b) Number of Families which doesn't buy Any NewsPaper = (100 - (40+20+10+5+3+4+2))%N = (100 - 84)%N = 16%N = 16/100*10000 = 16*100= 1600
