A 5-digit number is a perfect cube as well as a perfect square. When the number is divided by 4, the result is a perfect square but not a perfect cube. When the number is divided by 27, the result is a perfect cube but not a perfect square. Find the number.​

Answer»

Answer:

There are two ways to interpret this question, namely:

You want to know a NUMBER which can act as the perfect square root as well as the perfect cube root.

You want to know a number which is a perfect square as well as a perfect cube of an integer.

In the first case, the solution is simple. Any non-negative integer is a perfect square root as well as a perfect cube root of a larger number.

A non-negative integer, say 0, is the perfect square root of 0 as well as a perfect cube root of 0. This holds true for all non-negative integers beginning from 0 i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……….

In the second case too, the solution is simple but it entails a more logical approach than the first option.

A perfect square is a number which comprises of prime factors having powers which are a MULTIPLE of 2. Similarly, a perfect cube is a number which comprises of prime factors having powers which are a multiple of 3.

Any number which comprises of prime factors having powers which are a multiple of 6 will be the solution to your question; an EXAMPLE of which WOULD be 64 which is the perfect square of 8 as well as a perfect cube of 4. In this case, the number 64 can be represented in the form of prime factors (i.e. 2^6) having powers (i.e. 6) which are a multiple of 6.

2.

Write the prime factorization of the following numbers and hence their square roots:a)4761b)3364​

Answer»

Answer:

TAKING LCM of 4761

4761= 3×3×23×23

taking SQUARE ROOT both side

we GET √4761 = √3×3×23×23

= 3×23

= 69

Hence, the square root of 4761 is 69.

Answer»

Answer:

mark me as brainliest

Step-by-step explanation:

PHOTOSYNTHESIS is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. This chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek (), "light", and (), "putting together".[1][2][3] In most cases, oxygen is also released as a waste product. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called . Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.[4]

Composite image showing the global distribution of photosynthesis, including both oceanic phytoplankton and terrestrial vegetation. Dark red and blue-green indicate regions of high photosynthetic activity in the ocean and on land, respectively.

Overall equation for the type of photosynthesis that occurs in plants

Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromophores. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the PLASMA membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate () and adenosine triphosphate (ATP), the "energy currency" of cells.

In plants, algae and cyanobacteria, long-term energy storage in the form of sugars is produced by a subsequent sequence of light-independent reactions called the Calvin cycle. In the Calvin cycle, atmospheric carbon dioxide is incorporated into already existing organic carbon compounds, such as ribulose ().[5] Using the ATP and produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates, such as glucose. In other bacteria, different mechanisms such as the reverse Krebs cycle are used to achieve the same end.

The FIRST photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen or hydrogen sulfide, rather than water, as sources of electrons.[6] Cyanobacteria appeared later; the excess oxygen they produced contributed directly to the oxygenation of the Earth,[7] which rendered the evolution of complex life possible. Today, the average RATE of energy capture by photosynthesis GLOBALLY is approximately 130 ,[8][9][10] which is about eight times the current power consumption of human civilization.[11] Photosynthetic organisms also convert around 100–115 billion tons (91–104 ) of carbon into biomass per year.[12][13] The phenomenon that plants receive some energy from light – in addition to air, soil, and water – was first discovered in 1779 by Jan .

A group of x people were asked to choose their favourite fruit. One fourth chose kiwi, one third chose banana and two fifth chose orange and three people chose grapes How many people choose kiwi? (Express in terms of x) =​

Answer»

Step-by-step explanation:

LET's find the X no. of people first

x=1x/4+1x/3+2x/5+3=x/4+x/3+2x/5+3

=LCM=60

So, (15x+20x+12x)/60+3=

= 47x/60+3=x

3=x-47x/60

=(60-47)x/60=3

=13x=180

x=180/13

so 1/4 of x people chose kiwi

so 1/4×180/14

= 35/4 people chose kiwi

. In what time will * 400 amount to 448 at the rate of 4% per annum.​

Answer»

Answer:

COMPLETE step-by-step answer:

First, we have Principal AMOUNT = P = Rs. 400

Final Amount = A = Rs. 448

Rate of Interest = R = 4%

We will use the formula of Simple Interest that is S.I. = P×R×T/100

, where

S.I. = Simple Interest, P = Principal Amount, R = Rate on Interest, T = Time taken in years

Now, we will put in the values of P and R in the formula for S.I.

So, S.I. = 400×4×T/100

Now SIMPLIFY the value by ELIMINATING 100 from the denominator. We get:-

S.I. = 4×4×T=16T

We will now use the formula for Final amount which states that:-

Final amount = Principal amount + Interest that is A = P + S.I.

We will now put the values of P, S.I. and A.

So, 448= 400+ 16T

This is equivalent to writing:- 16T + 400 = 448

Now, we will take 400 to R.H.S

16T = 448 - 400 = 48

We will now take 16 from 16T to R.H.S

So, we get T=4816=3

3. A test contains 10 questions. A correct answer is awarded 2 marks, a wrong answer -1 marks and a question not answered is awarded 0 marks. A student attempts 7 questions and gets 8 marks. How many questions did the student answer correctly?​

Answer»

Answer:

5

Step-by-step EXPLANATION:

Let CORRECT attempts be x and incorrect attempts be y

Total attempts = x+y = 7 ...(1)

Total MARKS = 2x-y = 8 ...(2)

adding (1) and (2)

3x +y-y = 7+8

3x = 15

x = 5 and y = 2

So 5 correctly attempted questions
