Answer:
W = 882 N
Step-by-step explanation:
Given that,
The weight of a person, W = 90 kg
The value of acceleration due to gravity, g = 9.8 m/s²
We need to find the weight of the person on Earth. The formula for the weight of an object is given by :
W = mg
Substitute all the values,
W = 90 kg × 9.8 m/s²
W = 882 N
So, the weight of the person is equal to 882 N.

Answer:
12,345 tablets may be prepared from 1 kg of aspirin.
Step-by-step explanation:
The problem states that low-strength children’s/adult chewable aspirin tablets contains 81 mg of aspirin per tablet. And asks how many tablets may be prepared from 1 kg of aspirin.
Since the problem measures the weight of a tablet in kg, the first step is the conversion of 81mg to kg.
Each kg has 1,000,000mg. So
1kg - 1,000,000mg
xkg - 81mg.
1,000,000x = 81

x = 0.000081kg
Each tablet generally contains 0.000081kg of aspirin. How many such tablets may be prepared from 1 kg of aspirin?
1 tablet - 0.000081kg
x tablets - 1kg
0.000081x = 1

x = 12,345 tablets
12,345 tablets may be prepared from 1 kg of aspirin.
Answer: 3.20kg
Step-by-step explanation:
Hiro has 5 kilograms of potatoes and 2 kilograms of onions. The total kilogram of the produce will be:
= 5kg + 2kg
= 7kg
Since he plans to use 3.25 kilograms of potatoes and 550 grams of onions for a recipe. The total kilogram that he plans to use will be:
= 3.25kg + 0.55kg
= 3.80kg
Therefore, the total kilograms of the produce will not be used will be:
= 7kg - 3.80kg
= 3.20kg
Note:
1000grams = 1 kilogram
550gram = 550/1000 = 0.55kg
