An airplane is traveling at a constant speed of  600miles per hour. how many feet does it travel in  9seconds? remember that  1  mile is  5280  feet.

Step-by-step explanation:

Givens

To find the distance in feet, we need to transform, because, we have the speed in miles per hour, and we need to work with feet and seconds.

We know that 1 mile is 5280 feet, and 1 hour is 3600 seconds. We use this to transform the speed

Now, the airplane is traveling at a constant speed. So, the movement can be described as

, where is distance, is speed and is time.

Replacing all values, we have

Therefore, the airplane will travel 7,920 feet in 9 seconds.

a. -0.3 > -0.33

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
