4b. The error this student is doing is that he multiplies the first number but he must add the decenes of this result to the result of the multiplication of the second number and he is not doing that.
4c.- I told him the correct way to solve multiplications.
a) Multiply the first number and only write the units.
b) If the are decenes add then to the units of the result of the multiplication of the second number.
Example
72 9 x 2 = 18
<u>x9 </u> Just write the 8
8
72
<u>x 9</u>
648 9 x 7 = 63 + 1 from the previous operation
= 64
Magnitude of the net displacement: 7.0 miles
Step-by-step explanation:
In order to find the total displacement of the man, we have to resolve each displacement along the x- and y- direction.
Taking x as positive x direction and y as positive north direction:
- The first motion is 3 miles due east, so

- The second motion is 5 miles at
east of north, so:

So the components of the net displacement are

And so the magnitude of the net displacement is

So, he is 7.0 miles far from the house.
