Answer:
6000
Step-by-step explanation:
by observation, we can see that the digit in the thousands place is the number 5. This is the number that we need to either round up or down.
in order to determine if we should round up or down, we need to look at the number which is immediately to the right of this number. If this number is greater than 5, then we round the thousands place up, otherwise it remains the same
In this case, the number immediately to the right (i.e in the hundreds place) is the number 6. This number is greater than the number 5, hence we need to round the number in the thousands (i.e 5) place up to 6, giving us 6000
There would be 12 different digits.
The number of this always corresponds to the number in the base. Consider our current system which is base 10. We have 10 numbers we can use for digits (0-9). So a base 12 system would have to have 12.
Answer:
Step-by-step explanation:
Answer:
Surplus (extra) food from agriculture on river valleys
The first answer is A because (b+6) represents the sidewalk length. (With the pool length and the two corners, which equal 3 ft each.) Then, the sidewalk width would be (h+6) for the same reason. Multiply them and get the pool area plus the sidewalk area. But you only need the sidewalk area so you would subtract the pool area from the whole area, to get (b+6)(h+6)-bh, or A in the end.
Unfortunately, I do not know the answers to the rest of the problems. I still hope this helped though!
