Apiece of ribbon is cut into two shorter pieces in the ratio 2.8: 1.25. the difference in the length of the two shorter pieces is 80.6 cm

210.6 cm

Step-by-step explanation:

2.8-1.25= 1.55

1.55 units= 80.6 cm

155 units= 8060 cm

1 unit= 52 cm

You did not state what you were trying to find, but these types of questions are usually trying to find the original length, so I'm going to assume the same for this question.

2.8+ 1.25= 4.05

4.05 units= 210.6 cm

Ans: The length of the piece of ribbon is 210.6 cm.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

use formula for the circle a=3.14
