Ayellow ribbon is 7 centimeters long. a blue ribbon is 4 times as long as the yellow ribbon. how much longer is the blue ribbon than the yellow ribbon?

21cm longer.

Step-by-step explanation:

1. Y/R = 7cm, B/R = 7(4)cm

2. B/R = 28cm

3. 28cm - 7cm: as you are trying to find out how longer the b/r is relative to the y/r.

4. 28 - 7= 21cm.

In conclusion, the blue ribbon is longer than the yellow ribbon by 21cm.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
