it is a rectangle as after calculationPS= QR = √32 and PQ= RS = √ 13

thanks brother

1.6×10¹⁵ - 5× 10¹⁴= 10¹⁴(16-5)= 11× 10¹⁴

bro please can you explain this

just take 10¹⁴ common from both..

as 1.6 × 10¹⁵ = (1.6 ×10)× 10¹⁴ = 16× 10¹⁴.

so, after taking 10¹⁴ common it is (16-5)×10¹⁴= 11× 10¹⁴

:SONAR is an acronym for Sound Navigation And Ranging. It is an acoustic device used to measure the depth, direction, and speed of under-water objects such as submarines and ship wrecks with the help of ultrasounds. It is also used to measure the depth of seas and oceans.

A beam of ultrasonic sound is produced and transmitted by the transducer (it is a device that produces ultrasonic sound) of the SONAR, which travels through sea water. The echo produced by the reflection of this ultrasonic sound is detected and recorded by the detector, which is converted into electrical signals.

The distance (d) of the under-water object is calculated from the time (t) taken by the echo to return with speed (v) is given by 2d = v × t.

This method of measuring distance is also known as ‘echo-ranging’.

25= x+2x+2x+525=5x 25x= ---- = 5 525=5+2 (5)+2 (5)+525= 5+10+1525=25therefore the numbers are 5,10&15.

Answer={c} 4, 8, 134+8+1325

right answer is option D

hence option (d) is right

a . answers 13+5+7=25

c is the correct answer

option c is right answer

find the three number 4,8,13

correct option is 4,8,13

13+5+7=25 is the correct answer of this question

5+10+15=25 so,second is twice the first,and third is 5 more to second

c is correct answer for this

d is right option ........

4+8+13=254-4=88+5=13Therefore 3 is the correct answer

answer( c ) right 4, 8 ,13,4+8+13=25

D is the best answer

4*2=88+5=134+8+13=25So, the option number (c) is right

My answer is ( d ) none of these

given sum of three numbers is 25 then and the number are X+Y + Z = 225 and let given that second number is twice the first that isY=2X and given third exceeds that is Z =2X- 5 so to express-5 is equal to 225 and 5 x is equal to 30 that is X is equal to 30 by 5 equal to 6 therefore x is equal to 6 then the values of given numbers are x is equal to 6 Y is equal to 12 Z equal to 7

hence option d is right

correct option is (d)

........,..................…...…...…………

It's no. c and it is the only best answer

According to the question:-there are three numbersx, y and z.

y is X × 2and z is 5 + y

so, as we can see the answer is c) 4,8,13

because x = 4 y = 4 × 2 = 8 z = 8 + 5 = 13

so, c) 4, 8, 13 is the answer because it meets the parameters given by the question.

x+2x+(2x+5)=25x+2x+2x+5=255x+5=255x=25-55x=20x=4first number=4second number=8third number=13

Raghav is my name spread my fame

first num is 4,,second num is 8 third num is 13

option C is correct answer

ANSWER IS C 4,8,13 BECAUSE 8 IS DOUBLE OF 4 AND AFTER ADDING 5 IT 13

option. c is the best answer

25 = 4 + 4 x 2 + 4 x 2 + 5 25 = 4 + 8 + 8 + 525 = 25so the answer (C) 4, 8, 13 is correct

let the first number is x then second number is 2x and third is 2x+5A. to Qx+2x+2x+5=255x+5=255x=25 —5=20x=20÷5=41. x=42. 2x=4×2=83. 2x+5=8+5=134,8,13(option c is right)

x+2x+x+5=254x+5=254x=25-54x=20x=20/4x=5

x=52x=2*5=10x+5=5+5=10

Non of these

given that 2nd no. is twice of first

checking the options we get c options have this

checking other part 3rd no. exceeds 2nd no. by 5 hence checking this in option we get C one is correct . C option is correct for both case hence option C is correct

option=c) 4,8,13 because if we add = 4+8+3,it will be 25

let the first no.=xlet the second no.=2xlet the third no.=2x+5sum of all this no. is 25x+2x+2x+5=255x+5=255x=25-5x=20/5=41st no.=42nd no.=2x=2*4=83rd no.=2x+5=2*4+5=13

Ans:(c) 4,8,134+8+1325

answer is =c 4+8+13= 25

4,8,13 is the answer of this question

the answer is a 13 ,5,7

4 8 13 is the answer

5;10;15................

.

25=✖️+2✖️+525=5✖️25✖️=----=5525=5+2(5)+2(5)+(5)25=5+10+1525+25therefore the numbers are 5five, 10ten and 15agar answer sahi ti like karen agar galat hai to nichhe👇comment main batayen

c is the right answer

(c)4,8,13 is correct answer

right answer is A 13,5,7

Sum of all option's numbers are 25 so, all are same sum. By statement=the second number is twice of first number so, in third option the second number is 8 and number 8 is twice of first number that is 4(4*2=8)and in this option the third number is 13 and this is exceeds the second by 5(13-5=8)so first , second, third number are 4,8,13.

3,8,14 right answer now ok

X+2X+2X+5=25solve to get the answer

(C) 4 , 8 , 134 + (4×2) + (8+5) = 25

first no. 4second no. twice of first no.4+4=8third no. exceed the second no.by 5 8+5=13 ans (c) 4,8,13

(c) is the answervery easy

I don't know this answer sorry

the answer is 226270

sorry the correct answer is 979 if you plus

979 is the correct answer

Thanks

Since the grains of corn are found on the curved surface of the corn cob.

Total number of grains on the corn cob = Curved surface area of the corn cob x Number of grains of corn on 1cm^2

Now,find the curved surface area of the corn cob.r = 2.1 cmh = 20 cmLet l be the slant height of the corn cob. Then,l^2 = r^2+ h^2= (2.1)^2 + (20)^2=4.41 + 400=404.41l =20.11

C.S.A. of cone= πrl= 22/7 * 2.1 * 20.11= 132.73 cm^2

We know that, Total no. of grains on the corn cob= 132.73 * 4= 530.92

so, approximately there are 531 grains.
