Answer:
108 cm^2
Step-by-step explanation:
A trapezoid has an altitude of 12 cm. Its parallel sides measure 10 and 8 cm, respectively.
The base of trapezoid are 10 and 8 cm
Height of a trapezoid = 12cm
Area of a trapezoid formula = 
= 
=108cm^2
Answer:
14,400
Step-by-step explanation:
Multiple length, width, and height
30×20×24= 14,400
The potential energy is converted into kinetic energy.
Therefore, for conservation of energy we have:
mgh = (1/2) m * v ^ 2
From here we clear the speed:
v = root (2 * g * h)
The height will then be:
h = v ^ 2 / (2 * g)
Substituting the values:
h = (34) ^ 2 / (2 * (32))
h = 18.0625 feet
Answer: The pear before it fell was 18.0625 feet up in the tree.
To estimate round 389 to 400
400 / 20 = 20
answer would be B. 20
