5.	Known amount of length and width of a rectangle is 15 cm. What is the maximum area of the rectangle?
Answer» <P>// p = rectangle length l = rectangle width L = rectangular area // p + l = 15cm p = 15cm - l L rectangle = pl = (15cm-l) (l) = 15cm l - l² // then the maximum area is when p and l are equal // p = l // finds l by SUBSTITUTING p // p + l = 15cm l + l = 15cm 2L = 15cm l = 15cm / 2 l = 7,5cm p = l = 7.5cm // FIND the maximum area of the rectangle by substituting l // L rectangle = 15cm l - l² = 15cm (7.5cm) - (7.5cm )² = 112.5cm² - 56.25cm² = 56.25cm² So the maximum area of the rectangle is 56.25cm²

5.

Known amount of length and width of a rectangle is 15 cm. What is the maximum area of the rectangle?

Answer»

<P>// p = rectangle length

l = rectangle width

L = rectangular area //

p + l = 15cm

p = 15cm - l

L rectangle = pl

= (15cm-l) (l)

= 15cm l - l²

// then the maximum area is when p and l are equal //

p = l

// finds l by SUBSTITUTING p //

p + l = 15cm

l + l = 15cm

2L = 15cm

l = 15cm / 2

l = 7,5cm

p = l

= 7.5cm

// FIND the maximum area of the rectangle by substituting l //

L rectangle = 15cm l - l²

= 15cm (7.5cm) - (7.5cm )²

= 112.5cm² - 56.25cm²

= 56.25cm²

So the maximum area of the rectangle is 56.25cm²

13.

A solid box ,15 cm by,20 cm by 8 cm a new solid is format by removing cube 3 cm what percent original volume removed

Answer»

Volume of larger cuboid = L x B x H

L = 20 cm

B = 15 cm

H = 8 cm

Volume = 20 x 15 x 8 = 2400 cubic cm

Volume of cube = A x A x A

A = 3 cm

Volume = 3 x 3 x 3 = 27 cubic cm

%removed = (27/2400) *100 = 2700/2400 = 9/8 = 1.125%

So 1.125 % of original volume has been taken out

25.

Ten years ago Rudi was a third of his age now. The next fifteen years age comparison between Marlina and Rudi's age is 3: 5. How many years will Marlena's age of 5 years to come?

Answer»

»10 Years ago RUDI's age was 1/3 his age now.

»So, 10 years = 2/3 his age now.

»Age Rudi:

= 10: 2/3

= 10: 3/2

= 15 Years

»15 years LATER Marlina age: Rudi

= 3: 5

»Age Rudi 15 years later:

= 15 + 15

= 30

»5y = 30

y = 30 ÷ 5

y = 6

»Age of Marlina:

= 3Y

= 3 (6)

= 18 (15 years later)

= 18 - 15

= 3 years (now)

»Age of Marlina 5 years later:

= 3 + 5

= 8 years

AS in this series of alphabet We have to find the ANALOGICAL series as the better way to solve this question is we have to taken this alphabets in number series as it is a easy way to solve that type of questions

FHJL :- In the following alphabets

F =6

H=8

j= 10

L=12

Clearly , in this you are ABLE to see that there is a difference of two between each of the numbers

GIFH :- LET us convert it as number form

G = 7

I = 9

F=6

H=8

What we have see in this numbers ??

Let us solve it in this way

FHJL :- 6 , 8, 10, 12

___________________

GIFH :- 7,9,6,8

Compare each of the number with the down no. or the denominator of the number

For instance compare F with G there is a addition of 1 we have seen similarly in H and I there is also addition of number. Between J or F and L or H there is a difference of -4

___________________******************

Well , now it is a final solution of this question

NPMO :-

N=14

P=16

M=13

O=15

Clearly , you see that it is similar to GIFH

So, for final or correct answer we solve it as

N = 14 -1

=> 13

P = 16- 1

=>15

M =13 -4

=> 9

O = 15 - 4

=> 11

13 , 15 , 9 , 11 in alphabet form it is MOIK

So , the solution of this question is NPMO : MOIK

46.

If log2=0.301 then find the number of digits in 2¹⁰²⁴.

Answer»

Let X = (2)^1024.

Apply log on both sides, we get

= > log x = log(2)^1024

= > log x = 1024 log 2

= > log x = 1024 * 0.301

= > log x = 308.22

The CHARACTERISTIC of x = 308.

Hence, the number of digits in 2^1024 = 308 + 1

= 309.

Therefore, we can CONCLUDE that 2^1024 consists of 309 digits.

Hope this helps!
