We are given that the initial depth of snow is 10 cm
while the rate of melting is 1/3 cm per hour. So the melted ice after 3 hours
is:
melted = (1/3 cm/hr) * 3 hours = 1 cm
Hence the depth left is:
depth = 10 cm – 1 cm = 9 cm
Answer:
9 cm

Answer:
C.
Step-by-step explanation:
Comparing the sides: 20 = 12 + 8.
The largest side must be less than the sum of the other 2 sides for there to be a triangle.
No triangle can have these dimensions.
Step-by-step explanation:
you know, a single side cannot be longer than the other 2 sides combined.
otherwise, the triangle cannot "close".
so, it starts with 12 cannot be longer than 5 + n.
therefore, n must be at least 7.
and n cannot be longer than 5+12 = 17
7 and 17 I would normally rule out a well, because in these cases the triangle would just be a flat line, when the 3rd side is as long as the other 2 combined.
so, in reality for a real, visible triangle, the range of valid values is 8 .. 16.
that is 9 positive integer values.
A parallelogram is a quadrilateral with two pairs of opposite, equal in length and is parallel to one another.
A rectangle is a type of parallelogram.
So, yes, a rectangle is a parallelogram.
