Aradioactive substance has a decay rate of 0.044 per hour. how many grams of a 100 gram sample will remain radioactive after 2 hours? round the answer to the nearest tenth of a gram, and do not include the unit in your answer. if necessary, include a leading 0 with any decimals less than 1. for example, 0.4 instead of .4.

91.6

Step-by-step explanation:

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.
