Answer:
A=152
K= -Ln(0.5)/14
Step-by-step explanation:
You can obtain two equations with the given information:
T(14 minutes) = 114◦C
T(28 minutes)=152◦C
Therefore, you have to replace t=14, T=114 and t=28, T=152 in the given equation:
Applying the following property of exponentials numbers in (II):
Therefore 
can be written as 
Replacing (I) in the previous equation:
Solving for k:
Subtracting 190 both sides, dividing by -76:
Applying the base e logarithm both sides:
Ln(0.5)= -14k
Dividing by -14:
k= -Ln(0.5)/14
Replacing k in (I) and solving for A:
Dividing by 0.5
A=152
Answer:
Option A.
Step-by-step explanation:
According to this survey results :
Students : 80 like viking and 20 like patriot.
Teachers : 5 like viking and 15 like patriot.
In Option B it is given that patriot is more popular in students while viking is more popular in teachers which is not correct.
In option c patriot is equally popular in students and teachers, which is also not correct. because patriot is popular in 20% of students but 80% in teachers, which is not correct.
In option d there is no difference between students and teachers, this statement is also not correct because there is lots of differences in their choices.
In Option A it is said that viking is more popular in students but patriot is more popular in teachers. this is correct.
Answer:
6 n + 6 b + 1
Step-by-step explanation:
Simplify the following:
11 b - 7 - 3 n + 8 - 5 b + 9 n
Grouping like terms, 11 b - 7 - 3 n + 8 - 5 b + 9 n = (9 n - 3 n) + (11 b - 5 b) + (8 - 7):
(9 n - 3 n) + (11 b - 5 b) + (8 - 7)
9 n - 3 n = 6 n:
6 n + (11 b - 5 b) + (8 - 7)
11 b - 5 b = 6 b:
6 n + 6 b + (8 - 7)
8 - 7 = 1:
Answer: 6 n + 6 b + 1
Answer:
It is easier to calculate stresses in beam and an exact measure of strength of steel. • If two beams are made of same material and comparing the “section modulus” ... section modulus will be tougher and more capable to withstand larger loads. ... earth pressures and all forces for the anchored sheet pile wall in figure 3 below.
Step-by-step explanation:
Just subtract 6 from 84 until there are not any numbers left.
