Answer:
24hours
Step-by-step explanation:
let Evan be x, Tyler=x-12,equate;1/x+1/(x-12)=1/8,to get x=24 or 4.The correct value of x=24 because if you take x=4 means that Tyler=-8hours which is impossible
Answer:
<h2>Yes the circumference is about times greater than their diameters</h2>
Step-by-step explanation:
We will approach this problem by doing a check
Say the diameter of a circle is 4 cm
Hence the radius is 3 cm
We know that the circumference is 

The circumference is about 3 time bigger than the diameter
Let us try another case say the diameter is 6 cm
The radius is 3 cm

Answer:
the answer is 18
Step-by-step explanation:
Answer:
4.6%.
Step-by-step explanation:
The probability that a can of paint contains contamination(C) is 3.23%
P(C)=3.23%
The probability of a mixing(M) error is 2.4%.
P(M)=2.4%
The probability of both is 1.03%.

We want to determine the probability that a randomly selected can has contamination or a mixing error. i.e. 
In probability theory:

The probability that a randomly selected can has contamination or a mixing error is 4.6%.
