Step-by-step explanation:
Answer:
576 ways
Step-by-step explanation:
There are 4 choices for the column of pawn in the 1st row
There are 3 choices for the column of pawn in the 2nd row,
There are 2 choices for the column of pawn in the 3rd row, and
There is 1 choice for the column of the pawn in the 4th row
Which gives a total of 4! = 24
Also, the pawns are distinct, so there are 4! ways to place them in these chosen positions;
4! = 24
So, there are 24 * 24 possible ways
= 576 ways
Answer:
I need to know how many students there are to answer this question
a)
If the triangles are similar, the corresponding sides vary on the same proportion, so the ratios between the corresponding sides are equal.
For
To solve for x you have to multiply both sides of the expression by 20
b)
Following the same logic, the ratio between x and 20 is the same as the ratio between 6 and 8
6/8 can be simplifies as 3/4. Then multiply both sides by 20 to determine the value of x.
As mentioned above, when two triangles are similar, the corresponding sides are always in the same ratio, that is why the results in a and b are the same.
