Answer:
<em>45 minutes </em>
Step-by-step explanation:
We want to know how long it takes to an airplane to fly a distance of 375 miles, if the speed of the airplane is 500 miles per hour.
For this, we should divide the distance/speed to get the time that the plane needs.
T = 375mi/(500mi/h) = 0.75 hours
The plane needs 0.75 hours or 0.75*60 = 45 minutes to fly that distance.
Given:
It is given that surface area must be less than 150 cm².
Solution:
The Maximum Volume With Total Surface Area Less than 150 cm² is shown in the table.
From the table, it can be concluded that for r=3.00 cm and h=4.95 cm the surface area will be less than 150 cm² and the volume will be the maximum.
Calculate the volume.
Hence, the required dimensions are r=3.00 cm and h=4.95 cm.
Here is wht i would put
to add 678 to 303 u would line them up verticly like this
678
303
