Samir was standing facing East. He turned to his right and walked 5 metres, again turned to his right and walked 7 metres.
Then he turned to his left and walked 4 metres. Which direction
is he facing now?

He is now facing to the south, this is because,

He is currently facing east, and right of east = south

Then one more right turn would give, right of south = west

Next, he turns left of west = south

So, he is now facing to the south direction

Thanks!

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
