Weiming had 2 1/2 pies. He gave 1 3/8 pies to his friends. How many pies did he have left?

Answer»

Answer:

Step-by-step explanation:

he had 2 1/2 = 5/2 pies

he gave 1 3/8 = 11/8 pies to his friends

so he LEFT with (5/2 - 11/8 ) = (20-11)/8  after equalizing denominator

                                           = 9/8 = 1 1/8 pie

2. Prove that 3 + 25 is irrational​

Answer»

Answer:

Step-by-step explanation:

LET US ASSUME that 3 + 2√5 is a rational NUMBER.

So, it can be written in the form a/b

3 + 2√5 = a/b

Here a and b are coprime numbers and b ≠ 0

Solving 3 + 2√5 = a/b we get,

=>2√5 = a/b – 3

=>2√5 = (a-3b)/b

=>√5 = (a-3b)/2b

This shows (a-3b)/2b is a rational number. But we KNOW that √5 is an irrational number.

So, it contradicts our assumption. Our assumption of 3 + 2√5 is a rational number is incorrect.

3 + 2√5 is an irrational number

Hence proved

A vassel is in the from of a hemispherical bowl surmounted by a hollow cylinder of same diameter the diameter of the hemispherical bowl is 14cm and the total height of the vessel is 13cm find the total surface area of the vessel​

Answer»

Answer:

1144 cm SQUARE

Step-by-step explanation:

Let the radius and height of cylinder be r cm and h cm respectively.

Diameter of the hemispherical bowl = 14 cm

∴ Radius of the hemispherical bowl =

Radius of cylinder = r = 14/2   = 7cm

Total height of the vessel = 13 cm.

∴ Height of the cylinder, h=13 cm - 7 cm = 6 cm

Total SURFACE area of the vessel=

2(CSA of cylinder + CSA of HEMISPHERE)

SINCE, the vessel is HOLLOW

= 2(2πrh+2r square)

= 4πr(r+h )

= 4× 22/7 ×7×(6+7)cm2   = 1144cm2

Prove that 2√ 3 + 5 √2 is an irratinal number.​

Answer»

Step-by-step explanation:

Given:-

2√3 + 5√2

To FIND:-

Prove that 2√ 3 + 5 √2 is an irratinal number.

Solution:-

Let us assume that

2√3+5√2 is a RATIONAL number

It must be in the form of p/q

Where p and q are integers and q≠0

Let 2√3+5√2 = a/b

=> 2√3 = (a/b)-5√2

On SQUARING both sides then

=> (2√3)^2 = [(a/b)-5√2]^2

=>(2√3)^2 = [(a-5√2b)/b]^2

We know that

(a-b)^2 = a^2-2ab+b^2

=> 12 =[ a^2-2(a)(5√2b)+(5√2b)^2]/b^2

=> 12 b^2 = a^2-10√2 AB+50b^2

=> 10√2 ab = 50b^2-12b^2-a^2

=> 10√2 ab = 38b^2-a^2

=> √2 = (38b^2-a^2)/(10ab)

=>√2 is in the form of p/q

=> √2 is a rational number.

But √2 is not a rational number

It is an IRRATIONAL number.

This contradicts to our assumption.

2√ 3 + 5 √2 is not a rational number.

2√ 3 + 5 √2 is an irrational number.

Hence, Proved.

Used formula:-

  • (a-b)^2 = a^2-2ab+b^2

  • The numbers are in the form of p/q where p and q are integers and q≠0 called rational numbers.

  • The numbers are not in the form of p/q where p and q are integers and q≠0 called irrational numbers.

Used Method:-

  • Indirect method or Method of Contradiction

✏ A body is projected with a VELOCITY (u) 30m/s at an angle of 30° with the VERTICAL.

✏ We need to find the maximum height attained by body.

✏ The maximum height attained by body is GIVEN by ;

\footnotesize\longrightarrow\:\:\sf Maximum \:Height_{(attained \: by \: the \: body)}=\dfrac{(u_y)^2}{2g}=\dfrac{u^2\sin^2(\theta)}{2g} \\

But here the angle 'θ' is in horizontal ;

Here, the angle 'α' is in vertical.

Here, the angle MADE by the α is 30°

\footnotesize\longrightarrow\:\:\sf Maximum \:Height_{(attained \: by \: the \: body)}=\dfrac{u^2\sin^2( {30}^{ \circ} )}{2g} \\

Angle 'θ' can also be WRITTEN as :

A gardener has 1000 plants. He wants to plant these in such a way that the number of rows and the number of columns remain same. Find the maximum number of plants he needs more for this.​

Answer»

Step-by-step explanation:

Here, plants = 1000

Since the remainder is 39.

Therefore 31^2<100031

2

<1000

Next perfect SQUARE number 32^2=102432

2

=1024

Hence, number to be added

= 1024 – 1000 = 24

\therefore1000+24=1024∴1000+24=1024

Hence, the gardener REQUIRED 24 more plants.

Answer»

Answer:

Step-by-step EXPLANATION:

cos(90-theta)= sin(theta)

sec(90-theta)= COSEC(theta)

sin(90-theta)=cos(theta)

tan(90-theta)=cot(theta)

cot(90-theta)=tan(theta)

cosec(90-theta)=sec(theta)

so now GIVEN that substituting in given equation

sin(theta)cosec(theta)tan(theta)/sec(theta)cos(theta)tan(theta)

+ cot(theta)/cot(theta)

tan(theta)/tan(theta)= 1

since cosec(theta)=1/sin(theta)

sec(theta)=1/cos(theta)

sin(theta)* 1/sin(theta)/

1/cos(theta)*cos(theta)
