The first day, Brian saw 31 birds and twice as many squirrels as birds. The second day, Brian saw 20 birds and 42 squirrels. Which of the following is a good estimation of how many birds and squirrels Brian saw in the two days?

1 / 2 : 10 / 21 or

51 birds  / 104 squirrels

Step-by-step explanation:

Day 1 = 31 birds / 62 squirrels

Day 2 = 20 birds / 42 squirrels

31 / 62 = 1 / 2

20 / 42 = 10 / 21

1 / 2 : 10 / 21

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
