Answer:
The greatest number of rectangles that can be cut from the piece of metal = 12
Explanation:
The dimension of the piece of metal = 16cm x 20cm
That is:
Length of the piece of metal = 20 cm
Width of the piece of metal = 16 cm
The dimension of the rectangle = 6cm x 4cm
Length of the rectangle = 6cm
Width of the rectangle = 4cm
The diagram below illustrates how the rectangles can be cut from the piece of metal
Considering the diagrams drawn above, and counting the rectangles formed, we can conclude that the greatest number of rectangles will be cut using the approach on the left, hence the greatest number of rectangles that can be cut is 12
The greatest common factor is 1
The coordinates would be multiplied by 3, as the scale factor is 3, and it is a dilation, so we know the size increases.
Answer:
48
Step-by-step explanation:
Ratio: Blue:yellow=4:3

4x12=48
So basically, You make a "equation".
You add 4 and 3 which is 7.
So since you know there is 84 total cards. That will equal the "?". So you divide the 84 and 7 since that will show what you will multiply with 4 and 3 to keep the blue and cards equally balanced. So you multiply the 12 and 4. Which is 48.
So there are 48 blue cards. Hope this helped you C:
