Answer:

In geometry, Heron's formula (sometimes CALLED Hero's formula), named after Hero of Alexandria, gives the area of a TRIANGLE when the length of all three sides are known. UNLIKE other triangle area FORMULAE, there is no need to calculate angles or other DISTANCES in the triangle first.

Step-by-step EXPLANATION:

GIVEN that:18+9-15+3

=>30-15

=>15

2106 is DIVISIBLE by 9

9 DIVISIBILITY RULE is sum of all digits is multiple of 9

2106=2+1+0+6= 9

9 is the multiple of 9

so 2106 is divisible by 9

QUESTION NAHIN SAMAJH AAYA

ANSWER:

didn't UNDERSTOOD what the QUESTION is SAYING

ANSWER:

=(3-√5)/(3+2√5)

=(3-√5)/(3+2√5)×(3-2√5)/(3-2√5)

=(3-√5)(3-2√5)/(3+2√5)(3-2√5)

=[3(3-2√5)-√5(3-2√5)]/(3²-(2√5)²

=(3²-6√5-3√5+2(5))/(9-4(5)

=(9-9√5+10)/(9-20)

=(19-9√5)/(-11)

=–(19-9√5)/ 11

= –(19-9√5)/11

=(-19+9√5)/11

=(9√5-19)/11

=9√5/11 - 19/11 = a√5-19/11

Therefore,a=9/11

If it is (a√5-19)/11 then a=9

But according to question,a√5-19/11

So,answer is 9/11

Answer:

LET money RACHAEL had be x

money emilia had is 40+x.

so, KIMBERLY has 75+40+x.

so total money is 40+x+75+40+x+x=425

therefore x=90

Kimberly has (from above) 40+75+x

=205

Step-by-step explanation:

As we all know that vertically opposite angle USE to be of equal measure

So here the condition must be verified

Now our basic goal is to REPRESENT two equal angles in the form of LINEAR equations in 2 VARIABLES a and b

So if we take 60°

Then a+30=60

And b-20=60

So a+30=b-20 as according to question

So a-b=-50

Now

a=30 and b=80 from eq. (1) and eq.(2)

and a-b must be equal to -50

Now 30-80=-50

So -50 =-50

LHS=RHS

hence verified

Answer:

This is a typical question of funding the HCF.

So first of all we deduct 2 from both NUMBERS and then FIND their HCFs.

1092= 2 × 2 ×3 × 7 × 13

990= 2 × 3 × 3 × 5 × 11

So the Highest Common Factor here is 6. So the numbers, 1094 & 992, by dividing with 6 will give a reminder of 2, and 6 is the BIGGEST number to do it.

Answer:

33/6

Step-by-step explanation:

LET the age of esters BROTHER be x

then ester's age = 11x/3

difference  = 4

 11x/3 - x    = 4

 11x-3x/3    = 4

   8X          = 12

     x          = 12/8

     x          = 3/2

now age of ester = 11x3/2x3

                          = 33/6

Answer:

No NUMBER with given condition exists

Step-by-step explanation:

sum of digits in given number = 6+2+2+1+2+x+5 = 18+x

since 18 is ALREADY divisible by 3, so, for making the given number divisible by 3, x can TAKE any value which is multiple of 3 i.e. 0 or 3 or 6 or 9.

but , for making the number divisible by 11,

so difference of sum of alternate digits = (6+2+2+5)-(2+1+x)=15-(3+x)=12-x

so nearest multiple of 11 to 12 is 11 itself.

12-x=11

=>x=1

but when x=1 number will not be divisible by 3.

Hence, the given number with given conditions does not exists.

Answer:

(1) B is 25% greater than a --> b=1.25a --> b/a = 5/4 --> b is a multiple of 5. So, the units digit of b could be 0 as well as 5. Not SUFFICIENT.

(2) If b is decreased by 50%, the result is not an integer --> b/2 is not an integer --> b is not even. Not sufficient.

(1)+(2) Since b is not even, then its units digit cannot be 0, THUS from (1) its units digit must be 5. Sufficient.

Abstract

Interferometry has been a time-honored technique for surface topography measurement. Interferometric measurements of surface shape are relative measurement techniques in which the shape of a known surface is compared with that of an unknown surface, and the difference is displayed as a series of interference fringes. NOISE attached in the interference fringes can have catastrophic effects on the phase-unwrapping process, so denoising is essential before reconstruction. Some noise may be generated due to vibrations when multiple images over a finite time period are captured for reconstruction by phase-shifting technique. This harmful noise is drastically reduced when fast phase shifting–based single-shot parallel four-step combined with Fizeau interferometer is applied. Measuring the shape of STRONGLY curved surfaces using two-beam interferometry is very complicated due to the higher fringe density. This problem may be SOLVED by multiple-beam interferometry, thanks to the very sharp interference fringes. The experimental results show the FEASIBILITY and high precision of multiple-beam interferometr

ANSWER:

what's the VALUES of X and y....TELL me FAST

LET P be the principle amount

case 1

given

rate = 10% PER annum

time = 3 YRS

FINAL amount or sum = Rs. 6500

=> PRINCIPLE amount + simple interest = Rs.6500

=> P + (P x 10% x 3) = 6500

=> P + 0.3 P = 6500

=> 1.3 P = 6500

=> P = 6500/1.3

=> P = 5000

case 2

principle = Rs. 5000

rate = 8%

time = 2 yrs

S.I = Principle x rate x time

= 5000 x 8% x 2

= Rs. 800

final Amount or sum = Rs. ( 5000 + 800)

= Rs. 5,800
