At the beginning of a snowstorm, Ashley had 7 inches of snow on her lawn. The snow then began to fall at a constant rate of 3 inches per hour. Assuming no snow was
melting, how much snow would Ashley have on her lawn 3 hours after the snow
began to fall? How much snow would Ashley have on her lawn after t hours of snow
falling?

13 inches?

Step-by-step explanation:

if she already has 7 inches you would count by 2 for every hour.

3, 5, 7, (...) 9, 11, 13

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

because they could drop even lower..
