<span>the division of 412 divided by 97 can be estimated as:
412 can be estimated as: 400
97 can be estimated to 100
so, now on dividing 400/100 we get, the answer as 4.
To verify the estimation: when 412 is divided by 97, the answer is 4.24 which can be nearly written as 4 only.
Thus, our estimation was correct.</span>
Answer:
24cm
Step-by-step explanation:
A^2 + B^2 = C^2 soo 10^ + B^ = 26^2 so 100 + B^2 = 676 subtract 100 from 676. Then take the square root of 576 and you’ll get 24. So B = 24cm
Answer:
rational
Step-by-step explanation:
We observe that 20 is 4 more than twice 8. This suggests the time is 1 hour and the rates are
... scooter: 20 mi/h
... bicycle: 8 mi/h
_____
You can let b represent the rate of the bicycle in miles per hour. Then we have (for time in hours and distance in miles) ...
... time = distance/speed
... time = 20/(2b+4) = 8/b
... 20b = 8(2b+4) = 16b +32
... 4b = 32
... b = 8
The rate of the bicycle is 8 mph; that of the scooter is 2*8+4 = 20 mph.
