\(=4x^2-5x+9\)

put x = 1/2

= 4(1/2)² = 5/2 +9

= 1-5/2+9

= (2-5+18)/2

= +15/2

= 7.5

Given:

Length of the train = 240 m

Time taken on crossing the platform= 45 sec

Time taken to pass a signal board = 16 sec

Formula Used:

Speed of train = Distance traveled to cross the signal / Time taken

Calculations:

According to the formula,

Speed of train = Distance traveled to cross the signal / Time taken

⇒ 240/16 m/s

⇒ 15 m/s

Let the length of the platform be x.

Then, (x + 240)/45 = 15

⇒ x + 240 = 675

⇒ x = 435 m

Change in question x⁶ - 7⁶ factorise

x⁶ - 7⁶ = (x²)³ - (7²)³ = (x² - 7²) ((x²)² + x² x 7² + (7²)²)

(∵ a³ - b³) = (a - b) (a² + ab + b²))

= (x - 7) (x + ) (x⁴ + 49x² + 2401)

Given:

Upstream rate = 4 km/h

Speed of a man in still water = 10 km/h

Formula Used:

Speed of the man (boat) in still water = ½ [DOWNSTREAM rate + UPSTREAM rate]

Calculations:

Let the downstream rate be x kmph

According to the formula,

Speed of the man (boat) in still water = ½ [DOWNSTREAM rate + UPSTREAM rate]

⇒ 10 = (1/2) (x + 4)

⇒ 20 = x + 4

⇒ x = 20 – 4

⇒ x = 16 km/h

p(x) = 8x³ - 6x² - 4x + 3

p\((-\frac{1}{2})\) = 8\((\frac{-1}{2})^3\) - 6\((\frac{-1}{2})^2\) - 4 x \(\frac{-1}{2}\) + 3

= \(8\times\frac{-1}{8}-6\times\frac{1}{4}+2+3\)

= \(-1\frac{-3}{2}+5\)

Given:

Speed of stream = 1.5 km/h

Speed of a boat in still water = 8 km/h

Distance = 61.75 km

Calculations:

⇒ Rate Upstream = 8 – 1.5 = 6.5 km/h

⇒ Rate Downstream = 8 + 1.5 = 9.5 km/h

⇒ Time take to go upstream = 61.75/6.5 = 9.5 h

⇒ Time take to go downstream = 61.75/9.5 = 6.5 h

⇒ Total time = 9.5 + 6.5 = 16 h

Formula Used : 

Speed = distance / time

Calculations:

Let the distance traveled by Sonu and Amit be D_S and D_A respectively.

D_A  = ( speed × time )_A = 7.5 × 2 = 15 km

D_S  = ( speed × time )_S = 4 × 2 = 8 km

On applying Pythagoras theorem

Distance between Amit and Sonu = √(152 + 82)

⇒ Distance between Amit and Sonu =  √(15² + 8²)

⇒ Distance between Amit and Sonu = 17 km

∴ The distance between them after 2 hours is 17 km.

Given:

Speed of stream = 1.5 km / h

Speed of a boat in still water = 8 km / h

Distance = 61.75 km

Calculations:

⇒ Rate Upstream = 8 - 1.5 = 6.5 km / h

⇒ Rate Downstream = 8 + 1.5 = 9.5 km / h

⇒ Time take to go upstream = 61.75 / 6.5 = 9.5 h

⇒ Time take to go downstream = 61.75 / 9.5 = 6.5 h

⇒ Total time = 9.5 + 6.5 = 16 h

Formula used:

Average speed = Total distance/Total time

Distance = Speed × Time

Calculation:

Distance from A to B = 60 × (15/60) = 15 km 

Distance from B to C = 90 × (10/60) = 15 km

Average speed = (15 + 15)/(15/60 + 10/60) = 72 km/hr

∴ The average speed of his travel from point A to C is 72 km/hr

Given: 

The initial ratio of A and B is 1 : 4

Amount of B becomes 44 litres

Concept used:

When some fraction of mixture is taken out then the ratio of the remaining mixture is the same 

Calculation:

Let the initial ratio of the mixture be x and 4x respectively

And, 25% of the mixture is taken out then the quantity of mixture becomes 3x/4 and 3x 

Now, According to the question:

3x + 20 = 44

⇒ 3x = 24 

⇒ x = 8

∴ The initial Amount of A is 8 litre 

Given:

Unrepaired vehicle = 30 kmph, 30 minutes

Repaired vehicle = 50 kmph, 30 minutes

Formula used:

Speed = Distance / time

Calculations:

Calculating distance in segments

Segment 1: D1 = 30 × 0.5

⇒ D1 = 15 km

Segment 2: D2 = 50 × 0.5

⇒ D2 = 25 km

⇒ Total distance covered = 25 + 15

∴ total distance is 40 km

Given:

A beaker contains acid and water in the ratio 1 ∶ x. When 30 litres of the mixture and 5 litres of water are mixed, the ratio of acid and water becomes 2 ∶ 5.

Calculations:

In 30 litres of solution

Acid = (1 × 30)/(1 + x) 

water = (x × 30)/(1 + x)

according to question 

\(\frac{\frac{30}{1\ +\ x}}{\frac{30x}{1\ +\ x}\ +\ 5}\ =\ \frac{2}{5}\)

⇒ 30/(35x + 5) = 2/5

⇒ 70x + 10 = 150

⇒ x = 2

∴ The value of x is 2.

Given:

⇒ Quantity of chemical in mixture = 90 × 4/9 = 40 litres

⇒ Quantity of water in mixture = 90 - 40 = 50 litres

Let quantity of chemical and water added in to the mixture be a litres.

⇒ (40 + a)/(50 + a) = 11 : 13

⇒ 520 + 13a = 550 + 11a

⇒ a = 15

⇒ Quantity of water in new mixture = 50 + 15 = 65 litres

⇒ Total quantity of new mixture = 90 + 15 + 15 = 120 litres

∴ Required percentage = 65/120 × 100 = 54.166 ≈ 54%

Explanation:

• Endangered species are those that are at risk of extinction due to sudden rapid decline in their population or loss of their critical habitat.
• An endangered species is a type of organism that is threatened by extinction. Development can also endanger species indirectly. 
• Invasive species can be any kind of living organism such as an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism's seeds or eggs; that is not native to an ecosystem and causes harm to other species.
• Species found only in a particular area is known as Endemic species.

• Red Data Book keeps a record of all endangered animals, plants, and species. It contains a list of species that are in danger of becoming extinct.

• Extinct Species: Extinct animals are those species that are no longer living. This group includes prehistoric animals like dinosaurs and ice-age mammals, as well as modern species like the Dodo.
