Time taken to travel 340 km at speed of 85km/hr = 340/85=4 hrsHence the bus started at 9.15 A.M

teacher day is celebrated on 5 September

Volume of block of wood

= 20 cm × 80cm × 40cm

=64000 cm³

Volume of 1 cube = 20 × 20 × 20

= 800 cm³

No of boxes = 64000/800

= 80 boxes

galat h bhai

it's wrong

20×20×20=not 80020×20×20=8000

Cost of 24 pen is ₹56

Cost of 1 pen is ₹56/24 = ₹4

Cost of 18 pen is 18 × ₹4 = 72

145/5=29/1=29,, 87/1=87; 403 , 186/2=372; 403/1=403;

percentage change will be there= 86-77/86*10010.46 percentage

cash price of briefcase = 450cash down payment = 210

Put volume of triangle l×b×h =12×13×5 = 780

The right answer is '780

thanks bro

Rs 80 is the cp of ???

x - 18/x = 6

x² - 6x - 18 = 0

Discrimanat = b² - 4ac

= (-6)² - 4 × (1) × (-18)

= 26 + 72

= 98

the other root will be the conjugate of this root that is 2-√3

answer is option (2). 50

explaination:- perimeter of square=20

4s=20, s=5. so each side is 5.

width of sqaure=width of rectangle=5=b

length is double the width in rectangle so 5×2=10=l

area of rectangle = l×b

5×10=50cm²

so area of rectangle is equal to 50cm².

50 is answer please mark best i am new in this app

50 is the right answer

2)50 is the right answer of the following

I am agree with your answer but in answer sheet the answer was 12.5 percent

Let the CP of 20 pen = SP of 16 pen = xCP of 1 pen = x/20SP of 1 pen = x/16Gain = SP-CP =x/80Gain% ={ (x/80)/(x/20)}* 100 = 25%

nice

thanks

Let the number be x

As per given conditionx + 24 = 110x/10010(x + 24) = 11x10x + 240 = 11x11x - 10x = 240x = 240

Therefore, Number is 240

(d) is correct option

rupees =100 paisaSo50 rupees 90 paisa can be written as

1)50.90 Rupees Answer

the roots of the required quation be M and N let the roots of the equation 2x²+2(p+q)x+p²+q²=0 be a and ba + b = -(p+q)ab = (p^2 + q^2) / 2(a+b)^2 = (p+q)^2(a-b)^2 = (a+b)^2 - 4ab(a-b)^2 = -(p - q)^2we wanted the values of square of sum of the roots and square of difference of the rootsNow M = (a+b)^2 = (p+q)^2 and N = (a-b)^2 = -(p - q)^2M + N = 4pqMN = (p+q)^2 [-(p - q)^2]MN= -(p^2 - q^2)^2hence the required equation isx^2 - (4pq)x - (p^2 - q^2)^2 = 0

If you will post question in language of except English or Hindi then how India will understand ?

We know that the two last pages are 31 and 32 since their sum is 63. So the pages in the first half of the book are 1-16, and the second half 17-32.

He removed odd number of leaves in the first half (1 - smallest) and even number in second half (2-smallest). To maximize the sum of whats left, he should be removing pages 1&2 from first half and pages 17,18,19 &20 from second half.

Total number of pages is (1+32)(16) = 528. Subtract the pages that were removed. 528 - (1+2+17+18+19+20) = 451

Like my answer if you find it useful!

Cost of the book = Money I had - Money I have = 50 - 5 = Rs. 45.

Profit per pen = re.1profit for 45 pens = rs.45if profit is always in positive then loss for the month is -5so 45+x = -5x = -50so the loss is -50pencils sold = (50/0.40) = 125Do as same as this

pen is profit Rs, 1, profit 45 pens = Rs. 45, profit in positive then loss for month = -5; 45 + x = -5; x = -45 + -5=-50;; pencil sold = ( 50 / 0. 40) =125.

Put the values of a , b and cthen(xy^p-1)^q-r (xy^q-1)^r-p(xy^r-1)^p-qafter solving

P(5,r) = P(6,r-1)

We know that P(n,r) = n!/(n-r)!

=> 5!/(5-r)! = 6!/(6-r+1)!

=> (7-r)!/(5-r)! = 6!/5! (By rearranging terms)

Also n! = n(n-1)!

=> (7-r)(6-r)(5-r)!/(5-r)! = 6×5!/5!

=> (7-r)(6-r) = 6 (Cancelling terms)

=> r^2 - 13r + 36 = 0

=> (r-9)(r-4) = 0

Hence r = 4,9

are u in grade 9.

When you find ameanfor a set of numbers, all the numbers carry an equalweight. For example, if you want to find thearithmetic meanof 1, 3, 5, 7, and 10: Add up your data points: 1 + 3 + 5 + 7 + 10 = 26. Divide by the number of items in the set: 26 / 5 = 5.2.

workers daily wages no.of workers total money men 60 50 30,00 women 40 30 1200 children 20 20 400 =/100 4600 mean /f(x)=4600/100=46
