The perimeter of a rectangle is 202020 centimeters. The length is 666 centimeters. What is the area of the rectangle?

Answer» PERIMETER of a rectangle=2(length+BREADTH)
202020cm=2(666+breadth)
=2×166+2×breadth
=1332+ 2×breadth
202020-1332 = 2×breadth
= 200688 = 2×breadth
= 200688÷2 = breadth
= 100344 = breadth


So AREA of the rectangle=length× breadth
=666×100344
= 66,829,104 SQCM

An employer pays rupees 20 for each day a worker works and forfeits rupees 3 for each day a worker is idle. At the end of 60 days a worker gets rupees 280. For how many days did the worker remain idle?

Answer»

Let's say the no of DAYS the worker works is60-x and the no of days a worker stays idle=x. as he is given 20 rupees EVERY day for WORKING and forfeits 3 rupees for STAYING idle. The required equation is (60-x)20-x(3)=280=>1200-20x-3x=280
=>1200-280=23x=>920=23x=>x=40 So he remains idle for 40 days and works for 20 days.

Solve by Elimination by equating Coefficients method4. 5ax + 6by = 28;3ax + 4by = 18Class 10Content Quality Solution Required ❎ Don't Spamming ❎

Answer»

Given : 5ax + 6by = 28 ------ (1)


Given : 3ax + 4by = 18 ------ (2)


On SOLVING (1) * 3, & (2) * 5, we get


= > 15ax + 18by = 84


= > 15ax + 20by = 90


-------------------------


-2by = -6


y = 3/b.




Substitute y = 3/b in (1), we get


= > 5ax + 6by = 28


= > 5ax + 6b(3/b) = 28


= > 5ax + 18 = 28


= > 5ax = 28 - 18


= > 5ax = 10


= > ax = 2


= > x = (2/a).



Therefore, the value of x = (2/a) and y = (3/b).




Hope this helps!

Find the coordinates of mid point of the line segment joining A(3,6)&B(-5,-10)

Answer»

Coordinate of mid point of the LINE segment JOINING A (3,6) is in quadrant 1
coordinate of mid point of the line segment joining B (-5,-10) is in quadrant 2

37.

find the coordinates of the points which divide the line segment joining the point (a) A(2,-3)&B(5,6) in the ratio 2:3 (b) A(-2,-3)&B(3,7) in the ratio 7:2.

Answer»

(a) A(2,-3)&B(5,6) in the ratio 2:3


x= (m*x2 + N*x1)/(m+n)

x=(2*5 + 3*2)/5

x=(10+6)/5

x=16/5


y= (m*y2 + n*y1)/(m+n)

y= (2*6 - 3*3)/5

y= (12-9)/5

y= 3/5


(x,y) = (16/5,3/5)



(b) A(-2,-3)&B(3,7) in the ratio 7:2


x= (m*x2 + n*x1)/(m+n)

x= (7*3 - 2*2)/9

x= 17/9


y= (m*y2 + n*y1)/(m+n)

y= (7*7 - 2*3)/9

y= 43/9


(x,y) = (17/9,43/9)


38.

Using suitable identity (7x-9y) (7x-9y)

Answer» (a - b)(a - b) = {a}^{2} + {b}^{2} - 2ab \\ \\ (7x - 9y)(7x - 9y) \\ = {(7x)}^{2} + {(2y)}^{2} - 2(7x)(9y) \\ = 49 {x}^{2} + 81 {y}^{2} - 126xy

Answer» LET the no. Ihaki chose be x
When she multiples it by 100 it becomes 100x
When when she DIVIDES it into 4 QUARTERS, value of each quarter becomes 25x

Now when she ADD two quarters she will get 50x

When she subtracted 50x by 180 she gets 20

I.E. 50x-180=20
50x =200

x=4

Thus she chose the No. 4

Find the domain of 1/1-2sinx

Answer»

Hello! ! !

Hey dear here is your answer ___________

➖Function is f(X) = 1/(1 - 2sinx)
function is DEFINED only when 1 - 2sinx ≠ 0


➖Let 1 - 2sinx = 0
sinx = 1/2 = sinπ/3


➖we know, if sinФ = sinα then, Ф = nπ + (+1)ⁿ α
so, x = nπ + (-1)ⁿπ/3 , where n is INTEGERS


➖Hence, domain of f(x) is all real NUMBER except {nπ + (-1)ⁿπ/3}


➖e.g., domain ∈ R - {nπ + (-1)ⁿπ/3 , n∈I}

Hey guys please.. solve this question and I will mark this answer as brainlist ...Q 18

Answer»

The answer is
First we will MULTIPLY them with their total income

He SPEND on food is

32000*1/4=8000

He spend on house rent

32000*3/10=9600

He spend on education on children

32000 * 5/21=7619.04

Now we will add the product

8000+9600+7619.04=25219.04

Now we will SUBTRACT that from the total income

32000-25219.04=6780.96

The money LEFT with him is 6780.96.
