First translate the question into an equation.
"What percent" means x/100, "of 40" means times 40, "is 14" equals 14.
So we have (x)(40) = 14 or 40x = 14.
Dividing both sides by 40, we find that x = 0.35.
Now, we want to write our answer as a percent.
So we move the decimal 2 places to the right and we have 35%.
Answer:
Step-by-step explanation:
given that a bacteria culture initially contains cells and grows at a rate proportional to its size.
If P be the size then growth rate
where k is constant of proportionality
separate the variables as

If after 1 hour population is B (say)

then k = ln B - ln A
Using this
P(t) = 
b) P(e) = 
c) Rate of growth = 
Unless you give B value, d cannot be solved

Answer:
<h3>C. no solution</h3>
Step-by-step explanation:
Determine the number of solutions for each of the equations below. Be sure to
justify your conclusions. *
(z – 8)2 = -1
A. one solution
B. infinitely many solutions
C.no solution
D. x = 9
Given the expression;
<u>(z – 8)^2 = -1</u>
we are to find the nature of the solution;
Take the square root of both sides
(z – 8)^2 = -1
√(z – 8)^2 = √-1
z- 8 = √-1
Note that √-1 will give a complex number i to have;
z = 8 ± i
This therefore shows that the equation has no real solution.
Answer: Hi there! Joshua would make 2.20 an hour.
Step-by-step explanation:
The first step is to divide the amount he made in a day by the hour.
8.8 / 4 = 2.20
2.20 is the amount he makes an hour. If you want to make sure, you can multiply the 2.20 by the amount of hours he worked.
2.2 * 4 = 8.80
Have a lovely day!
