16201.	10. What should be added to (x – 4) (x + 6) to getthe product (x - 3)(x - 8) ?
Answer» Answer: -13X + 48 Step-by-step EXPLANATION: Let the answer be A. A + (X – 4) (x + 6) = (x - 3)(x - 8) A + (x^2 + 2x - 24) = x^2 -11x + 24 A = x^2 -11x + 24 - (x^2 + 2x - 24) = x^2 -11x + 24 - x^2 - 2x + 24 = -13x + 48

10. What should be added to (x – 4) (x + 6) to getthe product (x - 3)(x - 8) ?

Answer»

Answer:

-13X + 48

Step-by-step EXPLANATION:

Let the answer be A.

A + (X – 4) (x + 6) = (x - 3)(x - 8)

A + (x^2 + 2x - 24) = x^2 -11x + 24

A = x^2 -11x + 24 - (x^2 + 2x - 24)

= x^2 -11x + 24 - x^2 - 2x + 24

= -13x + 48

Answer»

Answer:

See the STARTING of each backet is a perfect square (n-1)^2

So the first term of 37TH bracket will be

7^(36^2)= 7^1296

So the terms are

7^1296 + 7^1297 + 7^1298 and so on

Take 7^1296 common

7^1296 ( 7^0 + 7^1 + 7^2...)

So it FORMS a GP and there are (2n-1)terms = 73 terms

Now apply the formula .

An elevator descends into a mine shaft at the rate of 6m /mins if the descent starts from 10m above the ground level how long will take to reach-350m

Answer»

Step-by-step explanation:

Considering the elevator to be at constant speed and the destination to be 350 m below ground level,

The elevator has to TRAVEL 10m till the ground, then 350 m more.

So, the total distance to travel is 360 m

If the elevator's speed is 6 metres/minute,

Then,

Time= Distance/Speed

= 360/6

=60 MINUTES

=1 hour

Huma, Hubna and Seema received a total of Rs. 2,016 as monthly allowance from their mother such that Seema gets 1/2 of what Huma gets and Hubna gets 5/3 times Seema’s share. How much money do the three sisters get individually?

Answer»

Answer:

Step-by-step explanation:

Let the share of huma be 'X'

Then,the share of SEEMA by the PROBLEM will be x/2

And the share of HUBNA will be 1 2/3*x/2=5x/6

Total money is Rs.2016

⇒x+x/2+5x/6=Rs.2016

⇒(6x+3x+5x)/6=Rs.2016

⇒14x/6=Rs.2016

⇒x=2016*6/14

⇒x=864.

Therefore,huma's share = x= Rs.864

Seema's share = x/2 = Rs.432

And Hubna's share = 5x/6= Rs.720 .

16229.

A man buys a certain number of articles at 15 for Rs 112.50 and sells them at 12 Rs for 108. find 1) his gain or loss% 2) the number of articles sold to make a profit of Rs 75.

Answer»

Answer:

CP PER article = 112.50/15 = Rs7.50 per article

SP per article = 108/12 = Rs 9 per article

Gain = 9-7.5 = Rs 1.5/ article

Gain% = (1.5/7.5)*100 = 20%

Total PROFIT = Rs75

Profit per article = Rs 1.5

No of ARTICLES sold = 75/1.5 = 50 articles

In right triangle ABC, Angle CAB =90 AF Perpendicular to CB and BD is median AC=2 CM AB= 2sqrt3 find AE

Answer»

GIVEN : In right triangle ABC, Angle CAB =90 AE Perpendicular to CB and BD is MEDIAN AC=2 Cm AB= 2√3

To find : AE

Solution:

Area of Δ ABC = (1/2) * AC * AB

= (1/2) * 2 * 2√3

= 2√3 cm²

Area of Δ ABC = (1/2) BC * AE

BC² = AC² + AB²

=> BC² = 2² + (2√3)²

=> BC² = 4 + 12

=> BC² = 16

=> BC = 4

Area of Δ ABC = (1/2) * 4 * AE = 2AE

2AE = 2√3

=> AE = √3

AE = √3 cm
