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)

Step-by-step explanation:

hope it helps

The prom committee is buying Brownies and Cookies. Brownies cost $2 each and Cookies cost $1.50. They need 45 treats and have $8
eimsori [14]

Answer:

Number of brownies = 30

Number of cookies = 15

Step-by-step explanation:

Given:

Cost of each brownie = $2

Cost of each cookie = $1.5

Total number of treats = 45

Total amount = $82.50

Find:

Number of cookies and brownie

Computation:

Assume;

Number of brownies = b

Number of cookies = c

So,

b + c = 45........eq1

2b + 1.5c = 82.50...........eq2

Eq1 x 2

2b + 2c = 90 ..................eq3

Eq 3 - Eq 1

0.5c = 7.5

c = 7.5 / 0.5

Number of cookies = 15

Number of brownies = 45 - Number of cookies

Number of brownies = 45 - 15

Number of brownies = 30
