How many different messages can be transmitted innmicroseconds using three differentsignals if one signal requires 1 microsecond for transmittal and the other two signals require2 microseconds each for transmittal. Signals in a messageimmediately follow one another. Note:Your final solution must not be in the form of a recurrence relation. Hint:The empty message is still considered a message.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

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
