Answer:
5 secs
Step-by-step explanation:
The height of the object is given as:

The moment when the object hits the ground, the height of the object will be 0 m.
Hence:

Solving this for t:
Divide through by 16 and move all parameters to the left hand side:


Since time cannot be negative, time, t = 5 secs.
The object will hit the ground after 5 secs.
of total sugar was drink by humming bird
<h3><u>Solution:</u></h3>
Given that,
When the Mario kept the humming feeder on Friday it had

Answer:
Approximately 17.88x or 
Step-by-step explanation:
Use pythagorean formula. In a rhombus the diagonals bisect each other and they are perpendicular, so you could have a right triangle with legs of 2x and 4x, the hypoteneuse would then be
which is approximately 4.47x. In a rhombus all 4 sides are the same, so multiply that by 4 and you get the perimeter. 4(4.47x) = 17.88x or if you simplify the radical instead it's
