9.	If 1 square shape takes 4 matchsticks to Construct one square , 2 squares need 7 matchsticks to construct it , 3 squares need 10 matchsticks to construct it . What will be the general rule for this pattern in algebra .Please answer with explanationtopic: Matchstick patternChapter : AlgebraGrade : 6Subject: MathematicsNCERT
Answer» Answer: GENERAL formula is x = 3N + 1 Step-by-step explanation: Here, 4 MATCHSTICK for first square 7 for second square 10 for third square 13 for fourth square So, in general let n be the number of squares and x be the number of matchsticks. The general formula is x = 3n + 1 where, n = Number of squares let check the algebraic formula Put n = 1, for first square Number of matchstick x = 3n+1 = 3×1+1 = 4 Put n = 2, for second square Number of matchstick x = 3n+1 = 3×2+1 = 6+1 = 7 Put n = 3, for third square Number of matchstick x = 3n+1 = 3×3+1 = 9+1 = 10 Therefore, General formula is x = 3n + 1

If 1 square shape takes 4 matchsticks to Construct one square , 2 squares need 7 matchsticks to construct it , 3 squares need 10 matchsticks to construct it . What will be the general rule for this pattern in algebra .Please answer with explanationtopic: Matchstick patternChapter : AlgebraGrade : 6Subject: MathematicsNCERT

Answer»

Answer:

GENERAL formula is x = 3N + 1

Step-by-step explanation:

Here,

4 MATCHSTICK for first square

7 for second square

10 for third square

13 for fourth square

So, in general let n be the number of squares and x be the number of matchsticks.

The general formula is x = 3n + 1

where, n = Number of squares

let check the algebraic formula

Put n = 1, for first square

Number of matchstick x = 3n+1 = 3×1+1 = 4

Put n = 2, for second square

Number of matchstick x = 3n+1 = 3×2+1 = 6+1 = 7

Put n = 3, for third square

Number of matchstick x = 3n+1 = 3×3+1 = 9+1 = 10

Therefore,

General formula is x = 3n + 1

Answer» <P>Answer: Rs. 3310 Step-by-step explanation: Given: Present value =₹ 10000 INTEREST rate =10% per annum Time =3 years To FIND the amount we have the formula, Amount (A)=P(1+(r/100)) n where P is present value, r is rate of interest, n is time in years Now substituting the values in above formula we GET, ∴A=10000(1+10/100) ⇒A=10000(11/10) ⇒A=121(10)(11) ⇒A=1331(10) ⇒A=₹ 13310 ∴ Compound interest =A–P =13310–10000=₹ 3310

37.

1. Find the compound interest on 10,000at 4% per annum for 3 years compoundedannually.

Answer»

<P>Answer:

Rs. 3310

Step-by-step explanation:

Given:

Present value =₹ 10000

INTEREST rate =10% per annum

Time =3 years

To FIND the amount we have the formula,

Amount (A)=P(1+(r/100))

n

where P is present value, r is rate of interest, n is time in years

Now substituting the values in above formula we GET,

∴A=10000(1+10/100)

⇒A=10000(11/10)

⇒A=121(10)(11)

⇒A=1331(10)

⇒A=₹ 13310

∴ Compound interest =A–P

=13310–10000=₹ 3310

45.	How many bricks having dimensions 20 cm × 5 cm × 5 cm are required to make a wall2.5 m long, 0.5 m broad and 5 m in height?
Answer» ☆ Given:- Dimension of WALL = 2.5 m × 0.5 m × 5 m Dimension of bricks = 20 cm × 5 cm × 5 cm = 0.2m × 0.05m × 0.05m ☆ To Find:- Number of bricks needed to make the wall ☆ Concept/Formula Used:- ▪︎VOLUME of CUBOID = length × BREADTH × height ▪︎No. of bricks = Volume of wall ÷ Volume of bricks ☆ Solution:- ♤ Finding volume of bricks Volume of bricks = length × breadth × height = 0.2 × 0.05 × 0.05 = 0.0005 m³ Hence, Volume of bricks is 0.0005 m³ ♤ Finding volume of wall Volume of walls = length × breadth × height = 2.5 m × 0.5 m × 5 m = 6.25 m³ Hence, Volume of wall is 6.25 m³ ♤ Finding number of bricks used Using the concept ; No. of bricks = Volume of wall ÷ Volume of bricks Putting the VALUES: = 6.25m³ ÷ 0.0005m³ = 12,500 ☆ Answer:- ▪︎12,500 bricks used to build the wall.

45.

How many bricks having dimensions 20 cm × 5 cm × 5 cm are required to make a wall2.5 m long, 0.5 m broad and 5 m in height?

Answer»

☆ Given:-

Dimension of WALL = 2.5 m × 0.5 m × 5 m

Dimension of bricks = 20 cm × 5 cm × 5 cm

= 0.2m × 0.05m × 0.05m

☆ To Find:-

Number of bricks needed to make the wall

☆ Concept/Formula Used:-

▪︎VOLUME of CUBOID = length × BREADTH × height

▪︎No. of bricks = Volume of wall ÷ Volume of bricks

☆ Solution:-

♤ Finding volume of bricks

Volume of bricks

= length × breadth × height

= 0.2 × 0.05 × 0.05

= 0.0005 m³

Hence, Volume of bricks is 0.0005 m³

♤ Finding volume of wall

Volume of walls

= length × breadth × height
