First, you have to know how many miles are in a kilometer. A mile is a total of 1609.54 meters, and a kilometer is 1000 meters. You have to do the next operation:270×1000%1609.54.
Hope workes for yoy
Answer:
x = -4
Step-by-step explanation:
-24 = 6x
________
Switch sides:
6x = -24
________
Divide both sides by 6:
6x/6 = -24/6
________
Simplify:
X = -4
Answer:
there's kinda alot of numbers there pal
Half-life (t½) is the amount of time required for a quantity to fall to half its value as measured at the beginning of the time period.
(t½) of C-14 is 5730 years, which means that after 5730 years half of the sample would have decayed and half would be left as it is.
After 5730 years ( first half life) 70 /2 = 35 mg decays and 35 g remains left.
After another 5730 years ( two half lives or 11460 years) 35 /2 = 17.5mg decays and 17.5 g remains left .
After another 5730 years ( three half lives or 17190 years) 17.5 /2 = 8.75mg decays and 8.75g remains left.
after three half lives or 17190 years, 8.75 g of C-14 will be left.
