If the number of terms in (1+x)^n be 11, find the 5th term and the value of n

Answer»

Given:

In a binomial expression (1 + x)ⁿ,

N = NUMBER of TERMS = 11

To find:

5TH TERM of the binomial expansion

Solution:

In a binomial expression (1 + x)ⁿ, nth term is defined by,

$T=\binom{n}{r}(x)^{n-r}(1)^r$

n = Number of terms

Therefore, 5th term of the given expression will be,

$T=\binom{11}{4}(x)^{11-4}(1)^4$

$=\frac{11!}{(11-4)!4!}(x)^7$

$=\frac{11!}{(7)!4!}(x)^7$

$=\frac{11\times 10\times 9\times 8}{4\times 3\times 2\times 1}(x)^7$

= 330(x)⁷

Answer» Answer: Length = 714.25 metres, Breadth = 285.7 metres. (approximately) Step by step explanation: Given: Ratio of length and breadth of rectangular PIECE of land = 5 : 2. Cost of fencing per m: Rs. 12.5 per m. Total cost: Rs. 25,000. To find: Length and breadth. SOLUTION: Total cost of fencing / Rate per m = Perimeter .°. 25000/12.5 = Perimeter Perimeter = 2000 metres Now, let the length be 5X and breadth be 2X. Perimeter of rectangular piece of land= 2( length + breadth) 2000 = 2 ( 5x + 2x ) 2000 = 2 × 7x 1000 = 7x X = 142.85 metres. (approx.) Length = 5x = 5 × 142.85 = 714.25 metres (approx.) Breadth = 2x = 2 × 142.85 = 285.70 metres (approx.) Thus, It's length and breadth are 714.25 metres and 285.7 metres (approx.) respectively.

Mathematics - Perimeter and AreaThe length and breadth of a rectangular piece of land are, in the ratio 5:2. If the total cost of fencing it at Rs. 12.5per meter is Rs. 25000, find its length and breadth.

Answer»

Answer: Length = 714.25 metres, Breadth = 285.7 metres. (approximately)

Step by step explanation:

Given:

Ratio of length and breadth of rectangular PIECE of land = 5 : 2.

Cost of fencing per m: Rs. 12.5 per m.

Total cost: Rs. 25,000.

To find: Length and breadth.

SOLUTION:

Total cost of fencing / Rate per m = Perimeter

.°. 25000/12.5 = Perimeter

Perimeter = 2000 metres

Now, let the length be 5X and breadth be 2X.

Perimeter of rectangular piece of land= 2( length + breadth)

2000 = 2 ( 5x + 2x )

2000 = 2 × 7x

1000 = 7x

X = 142.85 metres. (approx.)

Length = 5x = 5 × 142.85 = 714.25 metres (approx.)

Breadth = 2x = 2 × 142.85 = 285.70 metres (approx.)

Thus, It's length and breadth are 714.25 metres and 285.7 metres (approx.) respectively.

Answer» Given : If there is a DECREASE of 15% in price of a washing machine and SALE increases by 20%. To find : What will be effect on income. solution : Let's assume 100 washing machines are sold when price of each washing machine is 100. total income = 100 × 100 = 10,000 now there is a decease of 15% in price of a washing machine. so, new price of washing machine = 100 - 15% of 100 = 100 - 15 = 85 sale increases by 20% . so, new sale = 100 + 20% of 100 = 100 + 20 = 120 new total income = 85 × 120 = 10,200 total income is INCREASED by 200. so, % increase of income = (10,200 - 10,000)/10,000 × 100 = 200/10000 × 100 = 2 % Therefore , income increases by 2%. also read similar questions : The price of a washing machine inclusive of sales tax is ₹ 13,530.

If there is a decrease of 15% in price of a washing machine and sale increases by 20% then what will be effect on income

Answer»

Given : If there is a DECREASE of 15% in price of a washing machine and SALE increases by 20%.

To find : What will be effect on income.

solution : Let's assume 100 washing machines are sold when price of each washing machine is 100.

total income = 100 × 100 = 10,000

now there is a decease of 15% in price of a washing machine.

so, new price of washing machine = 100 - 15% of 100 = 100 - 15 = 85

sale increases by 20% . so, new sale = 100 + 20% of 100 = 100 + 20 = 120

new total income = 85 × 120 = 10,200

total income is INCREASED by 200.

so, % increase of income = (10,200 - 10,000)/10,000 × 100

= 200/10000 × 100

= 2 %

Therefore , income increases by 2%.

Answer» Given: The speed of the train excluding stoppages = 15 km/hr The speed of the train including stoppages = 11 km/hr To find: The stopping time for the train in 1 hr Solution: To find the average stopping time (in MINUTES) for the train per hour, we will use the following formula: $\boxed{\boxed{\bold{Average\:stopping\:time\:= \frac{Difference}{Speed \:excluding \:stoppages} \times <klux>60</klux> }}}$ where Difference between the speeds = 15 - 11 = 4 km/hr Now, by substituting the given values in the formula, we get $Average\:stopping\:time\:= \frac{4}{15} \times 60 \\\implies Average\:stopping\:time\: = 4\times 4 \\\implies Average\:stopping\:time\: = <klux>16</klux>\: minutes$ Thus, the train stops in 1 hr for 16 minutes. ---------------------------------------------------------------------------------- Also View: A train has an average speed of 45 km/without stoppages and 36 km/hr including stoppage time.

Speed of the train excluding stoppages is 15 km/hr and including stoppages is 11 km/hr. The trainstops in 1 hr for

Answer»

Given:

The speed of the train excluding stoppages = 15 km/hr

The speed of the train including stoppages = 11 km/hr

To find:

The stopping time for the train in 1 hr

Solution:

To find the average stopping time (in MINUTES) for the train per hour, we will use the following formula:

$\boxed{\boxed{\bold{Average\:stopping\:time\:= \frac{Difference}{Speed \:excluding \:stoppages} \times <klux>60</klux> }}}$

where

Difference between the speeds = 15 - 11 = 4 km/hr

Now, by substituting the given values in the formula, we get

$Average\:stopping\:time\:= \frac{4}{15} \times 60 \\\implies Average\:stopping\:time\: = 4\times 4 \\\implies Average\:stopping\:time\: = <klux>16</klux>\: minutes$

Thus, the train stops in 1 hr for 16 minutes.
