What you would do to “simplify” the equation is 18000-100 then divide by 50. The answer would be 358. Hoped this helped!
To find the unit rate you do
$1.39/8 oz.=.17
Then, you multiply the unit rate by the ounces
.17 * 14 oz. = $2.43
Answer:
18 minutes
Step-by-step explanation:
A = A₀ (½)^(t / T)
where A is the final amount,
A₀ is the initial amount,
t is the time,
and T is the half life.
A = 140 when t = 10. Solve for the half life:
140 = 700 (½)^(10 / T)
0.2 = ½^(10 / T)
log 0.2 = (10 / T) log 0.5
10 / T = 2.32
T = 4.31
When A = 40, t is:
40 = 700 (½)^(t / 4.31)
0.057 = ½^(t / 4.31)
log 0.057 = (t / 4.31) log 0.5
t / 4.31 = 4.13
t = 17.8
Rounded to the nearest whole number, it takes 18 minutes.
A. length = meter = m (base)
b. volume = cubic meter = m³ (derived)
c. mass = kilogram = kg (base)
d. temperature = kelvin = K (base)
