If an airplane's speed is 850 miles/ hours what is its speed in meters/ seconds? (1 mile = 1609.34 meters) a. 37,998 m/s b.1360m/s c.380m/s d.528 m/s i will ad you as a brainy list

Option C, 380 m/s

Step-by-step explanation:

The speed of an airplane is 850 miles per hour.

We have to calculate the speed in meters per second.

1 mile = 1609.34 meters

850 miles = 1609.34 × 850 = 136,793,9 meters

1 hour = 3600 seconds

Therefore Speed per second =

                                                 = 379.98 ≈ 380 m/s

Option C, 380 meter per second

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
