What is the area of the figure in square centimeters? Sandra used a square, a semicircle, and a right triangle to form the figure shown.

105.12 squared cm.

Step-by-step explanation:

Square:

8*8 = 64

Semi Circle:

A = pi * 4^2/2

50.24/2

25.12

Triangle:

(4*8)/2 = 16

64 + 25.12 + 16 = 105.12

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
