. If tan theta=3/4then(1 + sin 0) (1 - sin o)/(1 + cos 0) (1 - cos O)=_______. ​

Answer»

er:

Step-by-step explanation:

tan theta =3/4

Tan theta = PERPENDICULAR/ BASE

Thus, perpendicular =3k and base = 4k ( wher k is some positive INTEGER )

By Pythagoras theorem,

Hypotenuse = 5k

Therefore, sinO = 3/5 and COSO = 4/5

Then,

(1+ sinO)(1- sinO) / (1+ cosO )(1- cosO)

( 1 - sin²O) / ( 1- cos²O)

( 1- {3/5}²) / ( 1-{4/5}²)

( 1- 9/25) / ( 1- 16/25)

( 25-9 / 25) / ( 25 - 16/ 25)

=> 16/ 9

A shopkeeper gives two successive discounts on a article who semarked priceis ₹180 and selling price is ₹108.Find thefirst discount percentage if the second discount is 25%​

Answer» ONG>Answer:

Let the FIRST discount be x %

Second discount = 25 %

GIVEN that, Marked price = 180

Selling price = 108

Thus, price after first discount = \frac{100-x}{100}\times 180

100

100−x

×180

Price after second discount, as there is successive discount, the second discount MUST be applicable to the reduced price, so,

11. Answer the following The parking charges of a car in railway station for first two hours is 40Rs and 8Rs for each subsequenthour. Write down a equation and draw the graph. Find the following charges from the graph (1) For fourhours ( 2)For seven hours.​

Answer»

Basic Concept Used :-

Writing System of Linear Equation from Word Problems

1. Understand the problem.

  • Understand all the words used in stating the problem.

  • Understand what you are asked to find.

2. Translate the problem to an equation.

  • Assign a variable (or variables) to represent the unknown.

  • Clearly state what the variable represents.

3. CARRY out the plan and solve the problem.

\large\underline{\sf{Solution-}}

Let suppose that

  • Number of hours for which car is PARKED = 'x' hours

and

  • Total fare of parking = Rs 'y'.

So,

ACCORDING to statement,

  • The charges for first two hours = Rs 40

and

  • The charges for subsequent hours = Rs 8

This implies,

  • Charges for first two hours = = Rs 40

Now,

  • As total number of hours = x

  • Remaining hours is now = x - 2 hours

So,

  • Charges for (x - 2) hours = 8 × (x - 2) = Rs 8x -16

So, Total fare for parking car is

\rm :\longmapsto\:y = 40 + 8x - 16

\bf\implies \:y \: = \: 8x + 24 \: where \: x \geqslant 2

1. Substituting 'x = 2' in the GIVEN equation, we get

\rm :\longmapsto\:y = 8 \times 2 + 24

\rm :\longmapsto\:y = 16 + 24

\bf\implies \:y = 40

2. Substituting 'x = 3' in the given equation, we get

\rm :\longmapsto\:y = 8 \times 3 + 24

\rm :\longmapsto\:y = 24 + 24

\bf\implies \:y = 48

3. Substituting 'x = 4' in the given equation, we get

\rm :\longmapsto\:y = 8 \times 4 + 24

\rm :\longmapsto\:y = 32 + 24

\bf\implies \:y = 56

Hᴇɴᴄᴇ,

➢ Pair of points of the given equation are shown in the below table.

\begin{gathered}\boxed{\begin{array}{c|c} \bf x & \bf y \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf 2 & \sf 40 \\ \\ \sf 3 & \sf 48 \\ \\ \sf 4 & \sf 56 \end{array}} \\ \end{gathered}

➢ Now draw a graph using the points (2 , 40), (3 , 48) & (4 , 56)

➢ See the attachment graph.

From graph we CONCLUDED that,

\begin{gathered}\boxed{\begin{array}{c|c} \bf time(hrs) & \bf fare \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf 4 & \sf 56 \\ \\ \sf 7 & \sf 80 \end{array}} \\ \end{gathered}

a hemispherical bowl made of brass has inner diameter 10.5 find the cost of tin plating it on the inside at the rate of 16rupees per 100 cm square​

Answer»

Given :

  • DIAMETER of a hemispherical bowl made of BRASS = 10.5 cm
  • Cost of tin plating 100 cm² = Rs. 16

To find :

  • Cost of tin plating the hemispherical bowl

Concept :

→ Formula to calculate RADIUS :-

\boxed{ \sf \pmb{Radius = \dfrac{Diameter}{2}}}

→ Formula to calculate Curved SURFACE area :-

\boxed{ \sf \pmb{Curved~~surface~~area= 2\pi r^2}}

where,

  • Take π = 22/7
  • r = radius

Solution :

Firstly, we will calculate the radius of the bowl :-

Radius :-

\\ \dashrightarrow\sf \quad Radius = \dfrac{Diameter}{2}

\\ \dashrightarrow\sf \quad Radius = \dfrac{10.5}{2}

\\ \dashrightarrow\sf \quad Radius = \dfrac{ \not10.5}{ \not2}

\\ \dashrightarrow\sf \quad Radius = 5.25

\\ \sf \pmb{ \quad Radius \: of \: the \: bowl = 5.25 \: cm}

Now, calculate the CSA of the bowl.

\\ \dashrightarrow \sf \quad CSA = 2\pi r^2

\\ \dashrightarrow \sf \quad CSA = 2 \times \dfrac{22}{7} \times 5.25 \times 5.25

\\ \dashrightarrow \sf \quad CSA = 2 \times \dfrac{22}{ \not7} \times \not5.25 \times 5.25

\\ \dashrightarrow \sf \quad Circumference = 2 \times 22 \times 0.75 \times 5.25

\\ \dashrightarrow \sf \quad Circumference = 173.25

\\ \sf \pmb{\quad CSA \: of \: the \: bowl = 173.25 \: cm^2}

Cost of tin plating 100 cm² of the bowl = Rs. 16

Cost of tin plating 1 cm² of the bowl = 16 ÷ 100 = Rs. 0.16

Cost of tin plating the hemispherical bowl = Cost of tin plating 1 cm² of the bowl × CSA of the bowl

\\ \dashrightarrow \sf \quad Cost =0.16 \times 173.25

\\ \dashrightarrow \sf \quad Cost = 27.72

\\ \sf \pmb{ Cost \: of \: tin \: plating \: the \: bowl=Rs \: 27.72}

━━━━━━━━━━━━━━━━━━━━━━

Know More :

  • Area of circle = πr²
  • Circumference = 2πr
  • Diameter = 2 × Radius
  • Surface area of sphere = 4πr²
  • Volume of cylinder = πr²h
  • Volume of cone = 1/3 πr²h
  • Curved surface area of cone = πrl
  • Total surface area of cone = πrl + πr²h
  • Total surface area of cylinder = 2πrh + 2πr²
