43785 is not divisible by 2 because it's not an even number, and this also means it's not divisible by 10 because 10 = 2*5.
The sum of its digits is 4 + 3 + 7 + 8 + 5 = 27, which is divisible by 3 since 27 = 3*9, so 43785 is divisible by 3. We have 43785 = 3*14595.
It would be divisible by 9 if 14595 were also divisible by 3. That number has digital sum 1 + 4 + 5 + 9 + 5 = 24, which is divisible by 3, so 14595 is too and 14595 = 3*4865. So 43785 = 9*4865, and it is indeed divisible by 9.
14595 is clearly divisible by 5 because its ends with a 5.
Answer:
-5
Step-by-step explanation:
<u>Given that , </u>
- A number is taken away from 40 and the result is 45 .
<u>L</u><u>et </u><u>:</u><u>-</u><u> </u>
- The required number be x .
<u>According</u><u> to</u><u> Question</u><u> </u><u>:</u><u>-</u><u> </u>
40 - x = 45
- x = 45 - 40
- x = 5
x = -5
<h3>
Hence the required answer is -5 .</h3>
Answer:
229376
Step-by-step explanation:
Term n is given by 2ⁿ⁻¹, so the answer is
2¹⁵ + 2¹⁶ + 2¹⁷ = 229376
these questions don't need steps
The reciprocal of 5/8 is 8/5 all you have to do is flip it.
so if you are looking for the reciprocal to 2, then it is 1/2 because of the fraction properties
