Answer:

Bearing of R from S = S 45° E or 135°

The bearing of R from Q

= S 66.42° w or 246.42°

Step-by-step explanation:

Distance between R and S

RS²= RP²+PS²

RS²= 15²+15²

RS²=225+225

RS= √450

RS= 21.21

Angle at S

21.21= 15/sins

Sin s= 15/21.21

S= sin^-1 15/21.21.

S= 45°

90+45= 135°

Bearing of R from S = S 45° E or 135°

Distance between R and Q

RQ²= PQ²+PR²

RQ²= 35²+15²

RQ²=1225+225

RQ= √1450

RQ= 38.08

RQ= 15/sinQ

SinQ= 15/38.08

SinQ= 0.40

Q=23.58°

90-23.58 = 66.42°

66.42+180= 246.42°

The bearing of R from Q

= S 66.42° w or 246.42°

Ivan had a total of 9 pigs and chickens on his farm. There was a total of 30 legs. How many of each did he have ?
luda_lava [24]

Answer: 6 pigs and 3 chickens

Step-by-step explanation: you know that each pig has 4 legs and each chicken has 2 legs so start out by saying 9 pigs and 0 chickens which is 36 legs then try 8 pigs and 1 chickens and 8 times 4 = 32 + 2 which is 32 which is more than 30 then notice for every chicken there is you subtract 2 from 36

knowing this we can divide 6 by 2 and get 3 the number of chickens

so 6 pigs and 3 chickens      

hope this helps mark me brainliest if it helped

12x-24=180 what would x be when you solve this?
miskamm [114]

Hey there!

“12x - 24 = 180”

ADD by 24 on BOTH SIDES

12 - 24 + 24 = 180 + 24

CANCEL out: -24 + 24 because that gives 0

KEEP: 180 + 24 = 204

New equation:

12x = 204

DIVIDE 12 on BOTH SIDES

12x / 12 = 204 / 12

CANCEL out: 12 / 12 because of that gives you 1

KEEP: 204 / 12 because that gives the value “x”

204 / 12 = x

204 / 12 = 17

x = 17 ☑️

Good luck on your assignment and enjoy your day!
