Answer:
Step-by-step explanation:
Hi there,
We divide numbers where each of the hundreds, tens, and ones digits are evenly divisible by the divisor. The GOAL in this first, easy step is to get students used to two things:
To get used to the long division "corner" so that the quotient is written on top.
To get used to asking how many times does the divisor go into the various digits of the dividend.
Example problems for this step follow. Students should check each division by multiplication.
In this step, students also learn to look at the first two digits of the dividend if the divisor does not "go into" the first digit:
4 √ 248
4 does not go into 2. You can put zero in the quotient in the hundreds place or omit it. But 4 does go into 24, six times. Put 6 in the quotient.
Explanation:
The 2 of 248 is of course 200 in reality. If you divided 200 by 4, the result would be less than 100, so that is why the quotient won't have any whole hundreds.
But then you combine the 2 hundreds with the 4 tens. That makes 24 tens, and you CAN divide 24 tens by 4. The result 6 tens goes as part of the quotient.
Check the final answer: 4 × 62 = 248.

The negative cancels out each other
Answer:
-2 inches per hour
Step-by-step explanation:
Finding the average rate of change is just like finding the slope. So, take the y values (height) and subtract them and divide that by the difference in the x values (time).
( 3 - 9 ) / ( 8 - 5 )
= -6 / 3
= -2 inches per hour
Answer:
129.5 seconds.
Step-by-step explanation:
C = 3.14 (450)
= 1413
1413 (.40) = 565.2
562.5 + 300 + 300
= 1165.2
1165.2 / 9
= 129.5 seconds.
