Answer:
4
Explanation:
Since it's a flippy number, we can set each digit into ababa
Since it can be divisible by 15, which means it can be divisible by both 5 and 3.
Since it is divisible by 5, the last digit will be either 0 and 5, but it cannot be 0 because 0 cannot be the first digit, so last digit must be 5.
So, ababa --> 5b5b5
It can also be divisible by 3. According to de divisibility rule of 3, if the sum of all digit is divisible by 3 then the number is divisible by 3.
Sum of all digits = 15 + 2b
it's divisible by 3 when b = 0,3,6,9
The answer is 4.
There are 4 such number.
Answer:
B. Use prior knowledge about a topic to analyze a passage.
Explanation:
During a reading test on an SAT, you are required to read a passage and then answer questions about the topic presented.
All of the questions on the reading test are linked to the passage or passages, charts, graphs or tables presented.
There are 5 passages with 10-11 questions each.
Answer:
The equilibrium in the system is a dynamic equilibrium. At equilibrium, the rate of the forward reaction (CH4 decomposing into C2H2 and H2) is equal to the rate of the reverse reaction (C2H2 and H2 reacting to form CH4). At equilibrium, the concentrations of all substances are not changing.
Explanation:
Answer:
16.4 cm/0.4 ms
Explanation:
1: We know that the travel rate is 410 meters per second. We want to find a way in which we can cancel meters or seconds, and we can do that by multiplying 410m/1s with 100 cm/1m.
2. Now we want to get rid of that s, seconds, and we do so by multiplying prior fractions by 1s/1000ms.
3. Now we can diagnollay cross out m, and s. Leaving us with cm on top, and ms on the bottom. Which is what we want because we are calculating how many cm are for every .04 ms.
4: After that, you can multiply 410 and 100, to get 4,100. Whih leaves you with 4,100cm over 1000ms. Simplifying this, gives you 41, but that is NOT your answer. 41 cm, is for every ms, NOT every .04
5. Hence, you multiply 41 by .04 and get 16.4cm/.04ms.
