Question 7

Q7) USING Euler’s formula find the unknown.

Solution 7: (i) Faces-?,vertices-6,edges-12

Euler's formula: F+V–E=2

F+6–12=2

F=2+12–6=8

F=8

(II) Faces-5,vertices-?,edges-9

Euler's formula: F+V–E=2

5+V–9=2

V=2+9–5=6

V= 6

(iii) Faces-20,vertices-12,edges-?

Euler's formula: F+v–E=2

20+12–E=2 ,

E=20+12–2

E=30

Answer:

perimeter = 189 m

breadth = 10.5 m

2 ( l+ B ) = perimeter of rectangle

2 ( l + 10.5 ) = 189

l+ 10.5 = 189 ÷ 2

l + 10.5 = 95.5

l = 95.5 - 10.5

l = 84 m

area of the plot = l × b

= 84 × 10.5

= 882 m*2

ANSWER:

Mean

•The mean is the average of given data values. The formula to calculate the mean VALUE is:

Mean = Total of observation/Number of observation

For example, Mean of 2,5,6,7,8 is, (2+5+6+7+8)/5 = 28/5 = 5.6 .

•Mean = SUM of observation/Number of observation.

Mode

•Mode represents the value which is repeated maximum number of times in a given set of observation.For example, 11, 12, 13, 13, 14, 15 is data, where 13 is the mode value.

•Mode = Value repeated maximum number of times

x = 40 and x = - 45

Discarding the NEGATIVE value; we have speed of train = 40 km/h

Answer:

30

Step-by-step explanation:

10×3-6÷2×4+6×2                [∵ B.O.D.M.A.S RULE] (FIRST DIVISION)

=  10×3-3×4+6×2                  (Then multiplication)

= 30 - 12 + 12                        (After that addition)

= 30 + 12 - 12

= 42 - 12                                (At last subtraction)

= 30 (Ans)

Divisibility of 7 is remove the last DIGIT,double it,subtract from the TRUNCATED ORIGINAL number and continue doing it until only 1 digit is left If it is 0 or 7 number is divisible by 7.

• 427 = 2(7) = 49, 49-42 = 7

Hence it is divisible

• 3514 = 2(4) = 16, 351-16 = 335

Hence it is divisible by 7

• 861 = 2(1) = 2, 86-2 = 84

Hence it is divisible by 7

• 4676 = 2(6) = 36, 467-36= 431

Hence it is divisible by 7
