So you would set this problem up as 10 x 9 x 8 x 7, since none of the digits can be repeated. There are 5,040 4 digit passcodes possible.
Basically you are finding the volume of a rectangular prism of 3 by 2 meters cross section and 30 meters length. Volume = (3 m)(2 m)(30 m) = 180 cubic meters.
If 60% of the water has evaporated, 40% is left. Find 40% of 180 cubic meters to answer the 2nd part of this question.
B is correct 12 for find the y-intercept of 2x-y=-6
Answer:
D
Step-by-step explanation:
Using the sentences "One thing parents should not be worried about vaccinating their kids; still, the debate rages on," and the sentence "The real culprit undermining the public's safety is a <u><em>baseless</em></u> claim that vaccinations lead to autism." Using the fact that it is baseless, we can deduce that the author thinks it is not something to worry about. This means that we can rule out B and C. Also, A is not correct because the passage rarely mentions about this, so the answer is D.
