Two men p and q set off from a base camp r prospecting for o,p moves 40km on a bearing 205 degree and q moves 30km on a bearing

Mkey [24]

Answer:

(a) By cosine rule, /PQ/2=202+152−2×20×15×cos145°

= 400+225−600cos145°

= 625+600×0.8192

= 491.52+625

/PQ/2=1116.52⟹/PQ/=1116.52−−−−−−√=33.41

≊33km ( to the nearest whole number)

(b) By sine rule,

sin<QPR15=sin14533.41

sin<QPR=15sin14533.41

sin<QPR=15×0.573633.41=0.2575

<QPR=14.92°

∴ Bearing of Q from P = 25° + 14.92° = 39.92°.

≊40° (to nearest whole number)

15 1/2 times 2 1/8 ??

Gelneren [198K]

Answer:

$32 \times \frac{15}{16}$

Step-by-step explanation:

15 1/2 times 2 1/8 ??

$(15 \times \frac{1}{2} ) \times( 2 \times \frac{1}{8} )$

15 ×2 =30 +1 =31/2

2×8=16+1=17/8

$\frac{31}{2} \times \frac{17}{8}$

$\frac{527}{2 \times 8}$

527/16

$32 \frac{15}{16}$
