<span><em>Partial product </em>multiplication is the process of multiplying the numbers partially (respectively to ones, tens and hundreds) and adding them together in the end. For example, in order to find the product of 3 8 × 6 we should write that,
1) 3 8
× 6
___
4 8
2) 3 8
× 6
_____
4 8
1 8 0
3) 3 8
× 6
______
+ 4 8
1 8 0
______
2 2 8
<em>Regrouping </em>is the multiplication process when we add the partial products to the next tens and hundreds and so on without writing them down. For example, in order to find the product of 3 8 × 6 with the help of regrouping, we write that
4
3 8
× 6
___
228
, where the number 4 above 8 shows the tens of 4 (40), which is going to be added to the tens of the product of 30 times 6. The two processes are the same in a way that you are getting the same result. In the end, it is a multiplication process. The processes differ because of the methods we apply. In partial product multiplication, we break down the number in its ones, tens, hundreds steps and then calculate. However, in regrouping process we consider those steps without breaking them down. </span>
Let the speed of the water current be v.
total travel time = time to go upstream + time to return downstream to the starting point
Hence, 8 = time in hours = 6 / (4-v) + 6 / (4 +v) = 6*8/(16-v^2)
Hence, 16 - v^2 = 6, or v^2 = 10 or v = √10 miles / hour
Answer:
nothing
Step-by-step explanation:
who is the king of the world new beginner lol help me please
The angle above is a right angle triangle
And all right angle triangles are equal to 90degrees
So to find the missing area in the right angle triangle above you have to subtract the value you were given from 90
Which is mathematically written as
Angle 1= 90 degree- 22 degree
Angle 1= 68degree
Therefore the missing angle 1 is 68 degree
