Using section formula

x= 1(4) .+ 3(8) / 4y= 1(-3) + 3(5) / 4

x= 28/4 = 7y= 12/4 = 3

Therefore point (7,3) divides the line segment in the ratio 3:1

As this is simple intrest the intrest in each year wiil same.ex if sum is 900 an simple intrest is rs 20then first year SI amount is 900+20=9202nd year SI =920+20=940....3rd year Si=940+20=960by looking the above we can easily get the simple intrest i.e 960-940=20...so acc to question 3 yr SI=8154 yr SI=854so intrest=854-815=39for 1 yr it is39for 3 yr 39X3=117so sum(Principle)=815-117=698hope u got it.....

Let AB be the lighthouse and C and D be the positions of the ships.

Speed=distance/timeDistance=100

First, 10=100/t1t1=10sec

Second,8=100/t2t2=12.5sec

Beat by 2.5sec

i’m guessing you mean the ratio of the angles is 2:3:4 ?

2 + 3 + 4 = 9

any triangle has 180° total

180 / 9 = 20

40, 60, 80

Agreater angleof a triangle isoppositeagreater side

357000000=3.57*10^8

The speed of light in vacuum is 3 x 10^8 m/s. That means in one second it travels 300000000 metres.

As we know, in one year, there are 365 days; in each day there are 4 hours; in each hour there are 60 minutes and in each minute there are 60 seconds.

Therefore, the distance traveled by light in one year = 3 x 10^8 x 365 x 24 x 60 x 60 =1 light year = 9.4605284 × 1015meters

We need to move the decimal point 6 places to the right so the exponent of the 10s term will be negative:

0.00006=6.0×10^(-6)

A) 1.353*10^9

B) 1.2*10^10

A) 1.353×10×9this is the answer of A part of your question

Nice

Answer:1)50 RsExplanation :GivenCost of 8 books is 240RsNow cost of 5 book is (240×5)/8=150RsRavi gave 200Thus balance =200-150=50Rs

a jug holds 1*3/4 litter of tea how many mugs of capacity 1/4 litre can be filled out of

B={7,14,21,28,..........}

B÷(7,14,21,28...............)

b is the right answer

b is the correct answer

the correct answer is C

a=(x1+x2)/2 = 2-2/2 =0b=(y1+y2)/2 = -3+5/2 =1

So the value of a =0 and b=1.

75*800/100

= 75*8

= 600

15% = 15/100 = 3/20

The fundamental theorem of arithmetic (FTA), also called the unique factorization theorem or the unique-prime-factorization theorem, states that every integer greater than 1 either is prime itself or is the product of a unique combination of prime numbers.

Factorization of 120= 2*2*2*3*5

a) 1.6384 * 10^4

b) 1/(1.5625*10^4)

Fundamental theorem of arithmetic states and every composite numbers can be factorized in the form of prime numbers the factors will be unique except from the orders in which they were written.

Unique factorization of 120=2×2×2×3×5

A savings in a month is equal to30x+(1+2+3+.........+29)=30x+29/2(1+29)=30x+435B savings in a month is equal to=30x+(2+4+6+..........+58)=30x+29/2(60)=30x+870so B 's saving will be more

Innumber theory, thefundamental theorem of arithmetic, also called theunique factorization theoremor theunique-prime-factorization theorem, states that everyintegergreater than 1 either is aprime numberitself or can be represented as the product of prime numbers and that, moreover, this representation is unique,up to(except for) the order of the factors.

thanks for raising the doubt with usthanks

C = (..., -1, 0, 1, 2) ; As GivenD = (10, 11, 12, ...) ; As Given

So, 'U' means union, which means "the action of joining together or the fact of being joined together".C U D = (-infinity, 4) U [7, infinity).

and, n means intersection, which means "a point at which two or more things intersect"C n D = empty set; since none values in both of the given set coincides.

2 time question bheheya

Given Length of a room = 10m.

Given Breadth of a room = 6m.

We know that Area of a room = length * breadth

= 10 * 6

= 60m^2.

Giventhe breadth of the room = 2m.

Length of the carpet required to carpet the room = 60/2

= 30m.

Given that rate of carpet = 42 per metre.

Therefore cost of covering the floor = 42 * 30

= 1260 rupees.

100 years or 50 years

100 years or 50 years

11 years will be the least no. of full years as in 10 years the amount will be doubled and here we are talking about more than double and complete year then it will be 11 years

V2x^2+7x+5V2= V2x^2+5x+2x+5V2= x(V2x+5)+V2( V2x+5)= ( x+V2)( V2x+5)=0, x=-V2; V2x=-5; x=-5/V2
