Step-by-step explanation:
Alright, since there's 3.5*10^(-2) of salt for each liter of seawater, that means that for each liter added we add that to it, meaning that we multiply the amount of salt per liter by the total amount of liters, resulting in 3.5*9.88*10^(-2)*10^18=34.58*10^16 (by adding -2 and 18 we get 16). Since we only want 1 number in front of the decimal (that's not a 0) for scientific notation, we can move the decimal one spot to the left to make it 3.458. However, we can't simply move the decimal without changing the exponent - since we moved it one to the left, we must increase the power from 16 to 17 (conversely, if it moved to the right, we'd decrease the power), resulting in 3.458*10^17
Answer:
answer to the question is A
Answer:
25%
Step-by-step explanation:
Step one:
A store normally sells certain dress for $160 during a special sale
the store reduces the price of the dress to $120
Step two:
Percent reduction= change in price/initial price *100
Percent reduction= 160-120/160 *100
Percent reduction= 40/160*100
Percent reduction==0.25*100
Percent reduction=25%
