Question

solve the worksheet marks 60​

Answer 1

Step-by-step explanation:

13. Trinomial or polynomial

14. 16 men

15. 3 sides.

16. x = 180°-90° = 90°

z = 180°-30° = 150°

y = 180°-(180°-90°+30°) = 180°-60° = 120°

17. p(p-q) + q(q-r) + r (r-p)

= p^2 -pq +q^2-qr +r^2-pr

19. Volume of godown = l×b×h

= 60 × 40×30 = 72000m^3

Volume of one box = 0.8 m^3

So, no.of boxes that can be stored in the godown = 72000/0.8 = 90,000 boxes.

20. (2^-1×4^-1)÷ 2^-2

=(1/2×1/4)÷1/4

= 1/8 ÷ 1/4 = 1/8×4 = 1/2 = 0.5

23. Total surface area of cuboid

= 2(lb+bh+hb)

. = 2(8×6+6×5+5×8)

= 2(48+30+40) = 2× 118 = 236
