Check the picture below.
so then, the perimeter of that hexagon will just be the sum of all its 6 sides, or namely 3⅖ + 3⅖ + 3⅖ + 3⅖ + 3⅖ + 3⅖, or just 6( 3⅖ ).

<h3><u>Question:</u></h3>
The formula h = 120t-16t^2 gives the height h in feet of an object t seconds after it is shot upward from Earth's surface with an initial velocity of 120 feet per second. What will the height of the object be after 6 seconds?
<h3><u>Answer:</u></h3>
The height of object after 6 seconds is 144 feet
<h3><u>Solution:</u></h3>
<em><u>The formula that gives the height of an object is:</u></em>

Where,
h is the height in feet and t is the time in seconds
To find: height of the object be after 6 seconds
To find the height of the object be after 6 seconds, substitute t = 6

Thus height of object after 6 seconds is 144 feet
Each side is 50cm so 50cm × 4 sides = 200cm

Step-by-step explanation:
Answer:
2yrs
Step-by-step explanation:
Given parameters:
Amount of interest earned = $40
Principal = $400
Interest rate = 5%
Unknown:
Time taken for the money to be in bank = ?
Solution:
The formula for interest is given as:
I =
Where I is the interest
P is the principal
R is the rate
T is the time
So;
100I = PRT
T =
=
= 2yrs
