In 1975, the consumption of water for human use wasabout 3850 cu.km/year. It increased to about 6000cu.km/year in the year 2000. Find the per cent increase inthe consumption of water from 1975 to 2000. Also, findthe annual per cent increase in consumption (assumingwater consumption increases uniformly).

Answer»

Answer:

Percentage of consumption Increase is 55.844% and the Percentage increase annually is 2.23 %

Step-by-step EXPLANATION:

Consider the provided information.

It is GIVEN that in 1975, the consumption of water for human use was about 3850 cu.km/year. It increased to about 6000 cu.km/year in the year 2000.

First find how MUCH consumption of water increase.

6000-3850 = 2150 cu.km/year

The consumption of water increase 2150 cu.km/year now convert it into percentage

Percentage of consumption Increase = (Increase / Original) × 100

Percentage of consumption Increase =  (2150 / 3850) × 100

Percentage of consumption Increase =  0.55844 × 100

Percentage of consumption Increase =  55.844%

Now find percentage increase annually:

To find the ANNUAL per cent increase in consumption simply divide the percentage of consumption increase with total number of years form 1975 to 2000.

2000 - 1975 =75

The Percentage increase annually is = 55.84% / 25

The Percentage increase annually is = 2.23 %

Hence, Percentage of consumption Increase is 55.844% and the Percentage increase annually is 2.23 %

If x = 3+2 under root 2 so find the value of (x-1/x) ^3​

Answer»

ANSWER :-

The VALUE of (x - 1/x)³ is 128√2.

Solution :-

x = 3 + 2√2

Reciprocal on both sides

1/x = 1/(3 + 2√2)

Rationalise the denominator

\\ \\ \tt = \dfrac{1}{3 + 2 \sqrt{2} } \times \dfrac{3 - 2 \sqrt{2} }{3 - 2 \sqrt{2} } \\ \\ \\ \tt = \dfrac{3 - 2 \sqrt{2} }{ {3}^{2} - {(2 \sqrt{2})}^{2} } \\ \\ \\ \tt = \dfrac{3 - 2 \sqrt{2} }{9 - 4(2)} \\ \\ \\ \tt = \frac{3 - 2 \sqrt{2} }{9 - 8} \\ \\ \\ \tt = \frac{3 - 22}{1} \\ \\ \\ \tt = 3 - 2 \sqrt{2} \\ \\ \\ \bf \therefore \dfrac{1}{x} = 3 - 2 \sqrt{2} \\ \\

Now FIND the value of x - 1/x

x - 1/x = 3 + 2√2 - (3 - 2√2)

⇒ x - 1/x = 3 + 2√2 - 3 + 2√2

⇒ x - 1/x = 4√2

Cubing on both sides

⇒ (x - 1/x)³ = (4√2)³

⇒ (x - 1/x)³ = 64(2√2)

⇒ (x - 1/x)³ = 128√2

Therefore the value of (x - 1/x)³ is 128√2.

Question 4please slove it​

Answer»

Step-by-step explanation:

As BP = BC

BPC Is an isosceles ∆

Now.Let angle BPC be the x° then, angle BCP =x

According to SUM property of A triangle

ang. BPC+angBCP+angPBC = 180°

x°+x°+90° = 180° (ang.PBC = 90° as..Abcd is a RECTANGLE)

2x= 90°

x= 45°

ang..bpc= 45°=ang..bcp

Now, ang. BCD= ang. BCP+ang.PCD

90°= 45°+ ang. PCD (ANG.Bcd=90° as abcd is a rectangle& Ang. Bcp= 45 ° from above )

ANG. PCD= 45°

Answer»

Answer:

FIRST we have to arrange the given data in A.O (ascending order) .

33,35,43,46,55,58,64,77,87,90,92

Now ,MEDIAN = middle observation

= 33,35,43,46,55,)58,(64,77,87,90,92

= the middle observation is 58, so the median is 58.

HOPE YOU UNDERSTOOD THIS. you may get DOUBT that how to solve, when two numbers are left, simple you have to take mean of those ,then you will get the answer i.e, median.

Most probably two numbers will be left over when the numbers in the data is an EVEN NUMBER.

showbiz mothers present age is 6 times Sobers present age age 5 years from now will be one third of his mother's present age what are their present age​

Answer»

ANSWER:

Showbiz's present age is 5 while his mother's present age is 30.

Step-by-step explanation:

Let say,

Showbiz's Present age is, x

so,

Showbiz's Mother's age is 6 times of Showbiz present age.

x = 6x

after 5 YEARS his age will be 1/3 of his mother's present age.

so,

x+5 = 1/3 (6x)

x+5 = 2X

=> 2x-x = 5

=> x = 5

So, Showbiz's present age is 5, and his mother's age is 6(5) = 30.

Also, after 5 years his age will be 1/3 of his mother's present age, ( 1/3x30 = 10 )

which means,

5 year current age and after 5 years Showbiz will be of 10 years.

Result:

So their current ages are 5 and 30 years.

P.S:

I love detailed answers :)
