A wildlife organization plans to build a boardwalk across a marshland in their community. To measure the distance across the marshland, they set up ropes and pegs as shown in the diagram, and then took the following measurements: DE = 1.2m , DC = 1.5m , BC = 68.0m . If AB is parallel to DE how long is the distance across the marsh AB , to the nearest tenth of a meter?

at first, in 1635, the evening meetings had been just for women . .

what relationship between ideas is shown in the text above?

question 1 options:

location of events

similarity of events

timing of events

examples of an idea

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
