sheet of save earth as measures for 30 by 30 cm a strip of 6 cm is cut from all around find the area of the remaining sheet and also the area of the cut out

Answer»

Answer:

Side of sheet = 30 CM

$\boxed{ \blue{ \bf <klux>AREA</klux> \: of \: Sheet = {a}^{2} }} \\ \\ \Longrightarrow30 \times 30 \\ \\ \Longrightarrow 900 {cm}^{2}$

6 cm strip is cut from all side , then side will be reduced by 12 cm

Side of new sheet = 18 cm

$\boxed {\bf \blue{ Area \: of \: new \: Sheet = {a}^{2} }} \\ \\ \Longrightarrow 18 \times 18 \\ \\ \Longrightarrow324 {cm}^{2}$

Area of strip :

Area of sheet - Area of new sheet

$\Longrightarrow900 - 324 \\ \\ \boxed{\bf \green{Strip's \: Area = 576 \: {cm}^{2} }}$

$\underline {\pink { Class\:<klux>SIZE</klux> }}$

Difference between the TRUE upper LIMIT and true lower limit of a class interval is called the class size .

$For \:the \: Class \: interval \: 3.5 - 6.5$

Upper limit = 6.5
Lower limit = 3.5

The vertices A, B, C and D of a quadrilateral ABCD lie on a circle. ∠∠A is thrice ∠∠C and ∠∠D is twice ∠∠B. What is the difference between the measures of ∠∠B and ∠∠C?

Answer»

Answer:

TWICE the measure of angle A is thrice the measure of angle C:

Step-by-step EXPLANATION:

⇒ 2A = 3C

⇒ A : C = 3 : 2

Define x:

Let x be the constant ratio

A : C = 3x : 2x

Cyclic quadrilateral is a quadrilateral inscribed in a circle.

⇒ The sum of the OPPOSITE ANGLES of a cyclic quadrilateral is supplementary.

Solve x:

3x + 2x = 180

5x = 180

x = 36º

Answer»

Answer:

FOR 500 PEOPLE FOOD WAS FOR 40 DAYS

after 15 days only 25 days food left

again after 15 days 10 days food is left and total number of people present at last =100

we KNOW that 500 people can eat food upto 40 days so

in 1 DAY no of people can eat food = 500/40=12.5

so in 10 days no. of people can eat food = 12.5*10=125 people but there are only 100 people left they can eat food upto 110 days.

Two persons can paint a wall in 12 days. The firstperson works alone, pthe wall in 10 daysand then he leaves. If the second person was to paintthe remaining wall alone, in how many days will hecomplete the job?

Answer»

Answer:

SECOND PERSON ALONE WILL TAKE 60 DAYS TO COMPLETE THE WORK.

Step-by-step explanation:

two person shall always take less time then one person so i have exchanged 12 and 10.(can be don without changing also)

let work done in 1 day by first person = 1/x

and work done in 1 day by other person = 1/y

1/x + 1/y = 1/10 ---------- eqn 1

1/x = 1/12 --------- eqn 2

eqn 2 in eqn 1

therefore,

1/12 + 1/y = 1/10

1/y = 1/10 - 1/12

1/y = 6/60 - 5/60

1/y = 1/60

y= 60 days

32.	find the difference between the compound interest and the simple interest on certain sum for 2 years 5% per annum is 60 rupees . find the sum. Pls give proper answer
Answer» Let the sum be P = RS. 100. time T = 2 years, rate of INTEREST R = 5% per annum Simple interest = PRT/100= 100×5×2/100= Rs 10 Compound amount= P( 1+R/ 100)^T = 100×(1+5/100)² = 110.25 Therefore the compound interest = compound amount - principal = 110.25 - 100 = 10.25 the DIFFERENCE between the compound interest and simple interest = 10.25 - 10.00 = 0.25 if the difference between the CI and SI is Rs. 0.25 the principal = Rs. 100 if the difference between the CI and SI is Rs. 60 the principal = (100/0.25)×60 = 24000 Thus The Sum Is Rs. 25000. hope this helps you.

32.

find the difference between the compound interest and the simple interest on certain sum for 2 years 5% per annum is 60 rupees . find the sum. Pls give proper answer

Answer»

Let the sum be P = RS. 100.

time T = 2 years, rate of INTEREST R = 5% per annum

Simple interest = PRT/100= 100×5×2/100=

Rs 10

Compound amount= P( 1+R/ 100)^T

= 100×(1+5/100)²

= 110.25

Therefore the compound interest = compound amount - principal

= 110.25 - 100

= 10.25

the DIFFERENCE between the compound interest and simple interest

= 10.25 - 10.00

= 0.25

if the difference between the CI and SI is Rs. 0.25 the principal = Rs. 100

if the difference between the CI and SI is Rs. 60 the principal = (100/0.25)×60

= 24000

Thus The Sum Is Rs. 25000.

hope this helps you.

35.

- Wilson's mother is three times as old as him. Five years ago, she was four times as old as Wilson was then.Find their present ages.

Answer»

Answer:

15 years and 45 years

Step-by-step explanation:

Present ages:

LET the age of WILSON be n.

Age of her mother =3n.

Before 5 years:

Age of Wilson=n-5

Age of her mother=3n-5. Or 4(n-5)

3n-5=4n-20

-5+20=4n-3n

15=n

n=15 years.

Age of Wilson=15 years.

Age of his mother =15*3=45 years.

Answer»

Answer:

4cm and 3 cm

Step-by-step explanation:

Let length SHOWN in MAP of SECOND and third side be a and B.

Lenth of longest side/length shown in map

=Length of second side/length shown in map

300/6=200/a

=>a= 200×6/300= 4cm

Lenth of longest side/length shown in map

=Length of third side/length shown in map

300/6=150/b

=>b= 150×6/300 = 3cm
