You can just apply Pythagoras theorem i.e.Hypotenuse ^2 = Base^2 + Height^215^2=12^2+ Height^2Height^2= 225-144= 49Height = 7.So, Perpendicular length = 7 cm.

fifth son is Johny itself

-2√96 + 17 √6

-2√(16 × 6) + 17√6

-8√6 + 17√6

9√6

a=2 d=4nth term=a+(n-1)d=2+4n-4=4n-2sum of n terms=n/2(2+4n-2)=2n^2

Is it perfectly correct?

so-6-(-11)= 11-6= 5thanks

-17 hoga isaka answer agar -11se-6 hoga

Initially=5,00,000Rate=2%per hourNumber at the end of 2 hoursUsing Compound interest,

Amount=5,00,000(1+2/(100*1))²=5,00,000(102/100)²=102²*5*10=520200

1. 5/12. _7/13. 2.79/1=279/1004. 0.8/1=8/1

for 30 to be denominatormultiply and divide the fraction by 6-4*6/5*6=-24/30and for 45multiply and divide by 9=-4*9/5*9=36/-45

164 is the correct answer

ZUZeSecond letters are vowels

zuze is the right answer

5th son name is ZUZe

zuze since the second letters of other sons is a,e,i,o they are vowels so the other son's name is zUze

It is following a trendso A E I O U so it will beZUZE

the correct answer is zuze

hi

Perimeter of ractangle is 64

2l+2b20×2+2×1240 +2464

perimeter of rectangle is 2(l+b)so 2(20+12)2×32=answer

0.000000564= 564/1000000000= 5.64/10^9 * 10^2= 5.64 / 10^7= 5.64 * 10^-7

Therefore,0.000000564 = 5.67 * 10^-7

Factors of 24 are 1,2,3,4,6,12,24

Write the integers between the given pair write it in the increasing order 0 and minus 7

I will select red colour.

I will select green bottle

l will select green color

I will select colour blue bottle

I think it is black bottle

I will select red because it is in a large number

the colour which Will come that I will take

the colour which Will come that I will take

I will select red color is correct

12 is a correct answer

Let the principal be Rs.xTime=25/4 years.Amount=2*x=2xInterest=A-P=2x-x=xUsing SI=P*R*T/100,we getR=100*SI/(P*T)or,R=100*x/(x*25/4)or,R=100*4*x/25xor,R=16Answer:It will double itself in 25/4 years(6 years 3 months) at 16% p.a.

perimeter of ∆=3 .5+3.5+2.5 =7+2.5=9.5cm

Being an isosceles traingle, 2 sides will be of same length. Hence they are of 3.5cmand the 3rd side is of 2.5cm.hence perimeter is 3.5 + 3.5 + 2.5 = 9.5cm

Marks scored = 736

Total marks = 800

% = 736/800 × 100 = 736/8 = 92%

The smallest composite number is 4.

• The smallest prime number is 2.

The LCM of 4 and 2 is 4.

5minutes = (5/60) hours. Speed = Distance / time= 2.5/(5/60)= 2.5*12= 30 km/hr

this question answer 2

The answer to your question is 2

The largest positive integer that will divide 398, 436 and 542 leaving reminders 7, 11 and 15 respectively is the HCF of the numbers

(398 – 7), (436 – 11) and (542 – 15)

i.e. 391, 425 and 527

HCF of 391,425 and 527:

HCF of 425 and 391:

425 = 391 x 1 + 34

391 = 34 x 11 + 17

34 = 17 x 2 + 0

HCF of 425 and 391 = 17

Similarly, HCF of 17 and 527 = 17

Thus, HCF of 391, 425 and 527 = 17.

5 minutes = (5/60) = 1/12 hour.

Speed = Distance/Time= 2.5/(1/12)= 30km/hr

Sahi hai

not ryt but maine kr lyia hai tq for tried for my qsn

Given Observations = 5,4,0,2,2,4,4,3,3

No.of observations = 9

(i)

We know that

Mean = sum of observations/ no.of observations = 5+4+0+2+2+4+4+3+3 /9=27/9=3

So mean = 3

(ii) we know that median is the central or middle value of a series..

Given series 5,4,0,2,2,4,4,3,3

arrange it in either ascending or descending order

Ascending order - 0,2,2,3,3,4,4,4,5The middle value of the above series -0,2,2,3,(3),4,4,4,5

So median is '3'

(iii) Weknow that Mode is the Most repeated value in the series..

Given series 5,4,0,2,2,4,4,3,3Most repeated value in the above series is 4 (3 times)

so '4' is the mode
