Answer:

He can fertilize 2755 plants and have 40 mg of fertilizer left over

Step-by-step explanation:

First figure out how much each plant will require per year

98 mg * 4

392 mg

We need to change 1.08 kg to mg

There are 1000 g per kg   and 1000 mg per g

1.08 kg * 1000g/kg * 1000mg/g =1080000 mg

Divide 1080000mg by 392 mg per plant per year

1080000/392 =2755.102041

He can fertilize 2755 plants

2755 * 392 =1079960

1080000-1709960=40

He can fertilize 2755 plants and have 40 mg of fertilizer left over

Answer:

-2755 plants

-40mg  is left.

Step-by-step explanation:

Given the fertilizer amount is 1.08kg, and the amount per plant per year is (4*98mg):

#convert the weight of the fertilizer into grams then divide by quantity per plant to determine number of plants:

Number of plants = \frac{Fertilizer Amount}{Quantity per plant} =\frac{1.08*100000}{98mg*4} \\2755.1= 2755\\There are 2755 plants planted\\We subtract the fertilizer used from the total to find what is left:\\Left=total-used \\1080000mg-(2755*98*4) = 40mg\\Hence, 40 mg of the fertilizer is left over.

Bethany and Aidan each have candy bars that are the same size and shape. Bethany's candy bar is marked so that it can be broken
vivado [14]

Answer:

Step-by-step explanation:

This problem is most likely about what percentage of the candy does each individual have left. Since the phrase is explaining that each ones candy bar is the same size and can be broken into equally divided pieces then it is most likely about figuring out which one of the individual's has more candy left over when compared to the other's candy. This is possible since both candies are the same size but more information would be needed.
