a) The only factor with zeros is 400, which has 2 of them. Since the least-significant non-zero digits are not 2 or 5, the product 193×4 will not have any trailing zeros. Consequently, the product 193×400 = 77,200 will have 2 zeros.
b) Same reasoning, except with 3 zeros. 193×4000 = 772,000
c) The product of anything and zero is zero. There will be 1 zero in the product 193×400×0 = 0.
_____
If you like, you can factor out the trailing zeros:
... 193×400 = 193×4×100 = (193×4)×100 = 772×100
You can also use scientific notation to keep track of the trailing zeros. Here, the numbers end in 5 and an even number, so result in additional trailing zeros when multiplied.
... 192×500 = 192×5×10² = 960×10² = 96×10¹×10² = 96×10³ = 96000
Answer:
Step-by-step explanation:
Answer:
sometimes, if their average angle is over 45 degrees
never are 2 obtuse angles summing to 180 degrees
always. two 90 degree angles always sum to 180 which is a straight line
Answer:
22 students
Step-by-step explanation:
well it says 60 or better so that be 8 + 3 + 7 + 4
add it up to get 22 - cause its a 60+ score
So, the question is 63 is 30% of what number?
That can translate to the equation
63 = 30% · x or 63 = 0.3x
Divide by 0.3 and you get x = 210.
There are 210 students in band.
