Answer:
20
Step-by-step explanation:
The coordinates of A', B', C' and D' are , , and
Explanation:
The coordinates of ABCD from the graph is given by
A is , B is , C is and D is
The figure ABCD is reflected across the x - axis.
We need to determine the coordinates of A', B', C' and D' after it is reflected across the x - axis.
Since, we know that the rule to reflect across the x - axis is given by
Thus, using this rule, we shall determine the coordinates of A', B', C' and D'
and
Thus, the coordinates of A', B', C' and D' are , , and
STEP 1:
Divide the length of the ribbon by the size of the pieces.
12 inches= 1 foot
= 9 ft ÷ 15 inch pieces
convert ft to inches
= (12)(9) ÷ 15
= 108 ÷ 15
= 7.2 pieces from one roll
STEP 2:
multiply the number of pieces that can be cut from one roll by the number of rolls
= 7.2 pieces * 5 rolls
= 36 pieces total from 5 rolls
ANSWER: The greatest number of 15-inch pieces that can be cut from five 9-foot rolls is 36.
Hope this helps! :)
The answer would be the top right device.
