1)To stitch a pant 1 m 40 cm cloth is needed. Out of 35 m cloth, how many pants can be stitched and how much cloth will remain? 2) a) Multiply by using suitable rearrangement: 2 × 4 × 8 × 50 × 125
b) Find the value of 1549 × 499 using a suitable property of whole numbers.

3) a) During a month, the average temperature in day time of a place was 430C. The average temperature during night was recorded to be -30C. Find the difference between the average day temperature and the average night
temperature.
b) Subtract the sum of (-40) and 20 from the sum of (-50) and (-75).

4)A boy is flying a kite from the terrace of his house. The kite is 175 m above the terrace. If the terrace is 80 m from the ground floor, find the distance between the kite and the basement which is 8 m below the ground level.

5)Which greatest digit should replace m so that the number 10m 6415 is divisible by 11?

40 is the final : )

there are lots of ways.   pick's theorem tells us if the vertices are lattice points the area a is

a = b/2 + i - 1

where b is the number of boundary lattice points and i is the number of interior lattice points.

in the figure i count b=16, i=50 so

a = 8 + 50 - 1 = 57

let's try the shoelace formula.   the area is half the sum of the cross products of the sides.  

a(-2,6)   -2(2)-6(-5) = 26

b(-5,2)   -5(-3) - 2(-2) = 19

c(-2,-3) -2(-3) - (-3)(4) = 18

d(4,-3)   4(3) - (-3)(5) = 27

e(5,3)   5(3) - 3(1) = 12

f(1,3)     1(6) - 3(-2) = 12

a(-2,6)

each of the cross products is twice the area of the triangle with the associated side and one vertex the origin. so the area of abo=26/2=13.

area = (1/2) (26 + 19 +   18 + 27 + 12 + 12) = 57

that checks!

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
