The question asks you to find the total amount of rain after each hour, and has given you the ratio of 1.5 cm of rain in an hour. Therefore to find the rest, you’ll need to multiply the number of hours by the amount of rain in an hour:
2hrs - 3 cm
3hrs - 4.5 cm
4hrs - 6 cm
5hrs - 7.5 cm

I hope this helps and that I’m right! Good luck!! :)

frosja888 [35]

Answer: 2 bags

Step-by-step explanation:

First find the area of the yard.

The area given the units would be:

= Length * Width

= 45 * 55

= ‭2,475‬ ft²

Victor needs enough fertilizer to cover ‭2,475‬ft² but each bag covers only 1,250 ft².

The number of bags needed is therefore:

= ‭2,475‬ / 1,250

= 1.98

= 2 bags
