What situation could the graph represent? a. total rainfall during a rainy day
b. temperature as the weather changes from rainy to snowy
c. speed of a car starting from a stop sign and then approaching a stoplight
d. riding your bike slowly up a steep hill and then quickly down the other side

b

Step-by-step explanation:

It can only be b because the graph is steadily decreasing (negative slope). if it's raining, the temperature is above freezing, and then the rain would turn to snow if the temperature dropped below freezing. So that matches the graph.

For a, total rainfall in a day, the total would keep going up, so it would have a positive slope.

For c, the speed of the car would be at 0 at the beginning when in's at the stop sign, and the graph is starting out well above 0.

For d, the graph would have to go up then down to represent the hill.

This is because it is the most suitable option than other graphs. Let's verify all options.

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.

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9
