16.	George is reading a novel which has 303 pages. How many times does the digit 3 get printed in thepage numbers? How many pages are there which has only one 3 present in the page number?
Answer» Step-by-step explanation: Case 1: numbers with 3 are like 3,13,23,......,303 they are in AP with a=3, d=10 let the total number of PAGES with the digit 3 be n. 303 = 3 + (n-1)10 ⇒ n-1 = 300/10 = 30 ⇒ n = 31 number of pages = 31 case 2: number like 30,31,...39; 130,131,...139; 230,231,...239 from 30 to 39 - there are 10 numbers from 130 to 139 - there are 10 numbers from 230 to 239 - there are 10 numbers total = 10+10+10 = 30 but we have already counted 33,133 and 233. so number of pages = 30-3 = 27 case 3: the number 300,301 and 302. (303 has already been counted) so numbers = 3 So total number of pages = 31+27+3 = 61 every number having three has only one three except 33,133,233 and 303. number of pages with 2 threes = 4 number of pages with only one three = 61 - 4 = 57 total number of printing of 3 = 57×1 +4×2 = 57+8 = 65. So the digit 3 has been printed 65 times and number of pages with only one 3 present is 57 Thank Uh

16.

George is reading a novel which has 303 pages. How many times does the digit 3 get printed in thepage numbers? How many pages are there which has only one 3 present in the page number?

Answer»

Step-by-step explanation:

Case 1:

numbers with 3 are like 3,13,23,......,303

they are in AP with a=3, d=10

let the total number of PAGES with the digit 3 be n.

303 = 3 + (n-1)10

⇒ n-1 = 300/10 = 30

⇒ n = 31

number of pages = 31

case 2:

number like 30,31,...39; 130,131,...139; 230,231,...239

from 30 to 39 - there are 10 numbers

from 130 to 139 - there are 10 numbers

from 230 to 239 - there are 10 numbers

total = 10+10+10 = 30

but we have already counted 33,133 and 233.

so number of pages = 30-3 = 27

case 3:

the number 300,301 and 302. (303 has already been counted)

so numbers = 3

So total number of pages = 31+27+3 = 61

every number having three has only one three except 33,133,233 and 303.

number of pages with 2 threes = 4

number of pages with only one three = 61 - 4 = 57

total number of printing of 3 = 57×1 +4×2 = 57+8 = 65.

So the digit 3 has been printed 65 times and number of pages with only one 3 present is 57

Step-by-step explanation:

Let the DIGITS be x and y, with y>x, making y the units DIGIT and x the TENS digit

Therefore, y-x=1

x-y=-1

4x-4y=-4 ...Eq.1

Also,

5x+5y+1=10x+y

ABC is similar to ADB AB / AD = AC / AB AB ^2 = AD x AC (because AC = AD + CD = 4 + 9 = 13 CM) AB^2 = 4 x 13 AB^2 = 52 AB = √52 AB = 2√13 cm AB^2 = AD^2 + BD^2 (2√13)^2 = 4^2 + BD^2 16 + BD^2 = 52 BD^2 = 52 - 16 BD^2 = 36 BD = 6 cm Read more on Brainly.in - brainly.in/question/8764932#readmore

In right angled triangle ABC,BD is perpendicular to AC.If AD=4 ,DC=9,then find BD

Answer»

Answer:

6cm

Step-by-step explanation:

Given In right angled triangle triangle ABC, BD perpendicular AC if AD= 4, DC =9 then FIND BD

In a right angled triangle ABC, A is common, ANGLE ABC = angle ADB

BD is perpendicular to AC.

ABC is similar to ADB

AB / AD = AC / AB

AB ^2 = AD x AC (because AC = AD + CD = 4 + 9 = 13 CM)

AB^2 = 4 x 13

AB^2 = 52

AB = √52

AB = 2√13 cm

AB^2 = AD^2 + BD^2

(2√13)^2 = 4^2 + BD^2

16 + BD^2 = 52

BD^2 = 52 - 16

BD^2 = 36

BD = 6 cm

2 to the power 5 ×2to the power 0 + (-3)to the power 3 - (2/7) to the power -2

Answer»

ANSWER:

=2^5 *2^0+(-3) ^3-(2/7)^-2

=2^5-3^3-1/(2/7) ^2

=32-27-49/4

=128-108-49/4

=128-157/4

=-29/4 ( or -7.25)

HOPE this is the answer

note = x^0 = 1

Find the ratio of 90cm to 1.5m

Answer»

$\huge \boxed{ \fcolorbox{cyan}{red}{Answer : }}$

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

$\huge\bf\boxed{Ratio}$

1.5 = 1.5 × 100

= 150cm

1 m = 100 cm

ratio = 90 /150

= 30 × 3 / 30 × 5

= 3/5

= 3:5
