11. Find SP, if MP = 5500, discount = 20%. 12. A car is moving at a constant speed of 40km/hr. Find the distance it will
cover in 15 minutes.
13. Find the area of a rhombus, whose diagonals are 5cm and 8cm long.
14. Find the smallest square number which is divisible by each of the numbers
6.9 and 15.

please give me an answer for these question ​

11. 4400

Step-by-step explanation:

11.

solution :

MP = RS 5500

Discount = 20%

SP = MP - D % of MP

= 5500 - 20 % × 5500

= 5500 - 1100

= Rs 4400

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
