Answer:
5.6 days
Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229
Formula is given as;
N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25
e^(-0.1229t) = 0.5
(-0.1229t) = In 0.5
-0.1229t = -0.6931
t = -0.6931/-0.1229
t = 5.6 days
I think the answer is 8. After solving i got 8
-4x + 4!
The point 0,4 means that b will be equal to 4, as it’s the starting point. From there, if you go down 4 twice you have 2, and then -4.
Answer:
x ≈ 11.68 ( to 2 dec. places )
Step-by-step explanation:
Given
= 730 ( take log of both sides )
log
= log730
(x - 8)log6 = log730 ( divide both sides by log6 )
x - 8 =
≈ 3.68 ( add 8 to both sides )
x ≈ 11.68 ( to 2 dec. places )
Jaylan: Juice/Water = (3/4)/(1/5) = 15/4
Water/Juice = (2/3)/(1/6)=4/1 or (16/4) in Rene's .
Rene's combination has more water than Jaylan's limeade, which results in a milder lime flavor. Given that Rene's has more water and both have the same amount of lime juice (assume ratio), Rene's limeade has a milder lime taste.
What is combination in math?
Both "COMBIN" and "nCr" here redirect. See Combination (disambiguation) and NCR for further usage (disambiguation).
A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant (unlike permutations). Three fruits, such as an apple, an orange, and a pear, for instance, can be combined into three different pairs: an apple and a pear, an apple and an orange, or a pear and an orange. A k-combination of a set S is officially defined as a subset of S's k unique members. So, if and only if each combination has the same elements, two combinations are said to be identical.
