After 8.00 min, 75.0/2 = 37.5 g of the sample remains.
After another 8.00 min (total 16.0 min), 37.5/2 = 18.75 g remains. (Equivalently, 75.0/2^2 g)
After another 8.00 min (total 24.0 min), 18.75/2 = 9.375 g remains. (Or 75.0/2^3 g)
Finally, after another 8.00 min (total 32.0 min), 9.375/2 = 4.6875 g remains (or 75.0/2^4 g), approximately 4.69 g.
No it doesn’t because in a function you can’t use a number twice on an input or output
Lukyfkiyfkiukyjk that's your answer dudes
X of 20% = y
x - y = 75
x = total amount
y = discounted amount
x * 20/100 = y
x * 0.2 = y
replace y with 0.2x in other equation
x - y = 75
1x - 0.2x = 75
0.80x = 75
x = 75/.8
x = 93.75
Check:
93.75 * 20/100 = 18.75
93.75 - 18.75 = 75
x = 93.75
y = 18.75
Answer: Total amount without discount is $93.75
//BTW not sure about this, but kind of make sense
12 is 75% of what
is means equals, of means multiply
12 = 75% * what
12 = .75 * what
divide each side by .75
12/.75 = .75 * what /.75
16 = what
12 is 75 percent of 16
the answer is 16
