Answer:
1) 500mg/1000 = 0.5g of salt. So, 200mg of sodium equals 500 mgs or 0.5g of salt.
2) 6540 multiply the mass value by 1000
3) Instead of 80kg im thinking that you ment g
Weight of box = 4 kilograms
1 kg = 1000 g
4kg = 1000*4 = 4000 grams
Therefore,
Weight of box = 4000 g
Weigh of one orange = 80 grams
Let,
x be the number of oranges in box.
80x=4000
Dividing both sides by 80
There are 50 oranges in the box.
4) 30weeks
Step-by-step explanation:
From the question given,
Peter's weight = 105kg
Now, Peter wants to lose 500g per week i.e
Peter wishes to lose = 500/1000 = 0.5kg per week.
The mass losed by Peter = 105 —90 = 15kg
Now if Peter losed 0.5kg in 1week, then he will lose 15kg in = 15/0.5 = 30weeks
Therefore, it will take Peter 30 weeks to have a mass of 90kg
