The amount of radioactive material in a sample halves every 10 hours. By what percent does the
population change each hour?
OA) 6.7% growth
O B) 93.9% decay
O C) 6.7% decay
OD) 107.2% decay

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

answer: d. $20

step-by-step explanation:

just took the test

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
