6300 kg?Answer in standard form please.
1 answer:
Answer:
44.1 x 10^-2
Step-by-step explanation:
Since one grain
= 7 x 10^-5
6300kg = 7 x 10^-5 x 6300
Put 6300 in standard form
7 x 10^-5 x 6.3 x 10^3
Multiply the whole numbers and add the exponents
7 x 6.3 x 10^-5 + 3
44.1 x 10^-2
There are 44.1 x 10^-2 grains of sand in 6300kg

Investment = $5,000
Annual Interest = 5%
5000/100 x 5/1
50×5 = 250
First year interest = $250
Therefore, 250 x 20
= $5,000
