The test organism ferments sucrose best under reduced oxygen conditions.
The sample was incubated less than 24 hours, which allowed for only limited fermentation.
The media was contaminated.
The organism is an obligate aerobe and therefore can only grow inside the Durham tube.
The media was prepared wrong.
The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
The test organism did not ferment sucrose.
1)The test organism ferments sucrose best under reduced oxygen conditions.
2)The sample was incubated less than 24 hours, which allowed for only limited fermentation.
3)The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
Answer:
7 large stuffed animals and 20 small ones
Explanation:
Solve the system of equations
13S + 12L = 350
S + L = 27
L = 7
S = 20
Answer:
Explanation:
If John needs to ensure a 40% profit, John needs to sell the pines at a price that would give 40% more money back than he spent.
Since John needs to make back all of the money he spent, plus another 40%, John needs to get back 140% of what he spent.

John spent $3500.
140% of $3500 is $4900.
So, John must bring in $4900 (revenue) selling all 15 pines to achieve a 40% profit.
However, the question asks for the price of a single pine. To find the unit price of a single pine, divide the total revenue by 15.

The sum of the two numbers is equal to 70.
- Let the first number be x.
- Let the second number be y.
In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).
Translating the word problem into an algebraic expression, we have;
Two numbers differ by 8:
....equation 1.
The product of the two numbers is 713:
....equation 2.
To calculate the sum of the two numbers:
First of all, we would solve for each of the unknown variables (x and y).
From eqn. 1, we have:
....equation 3.
Substituting eqn. 3 into eqn. 2, we have:

Solving the quadratic equation by factorization, we have:

y = -23 or 31.
For the value of x, when y = 31:

x = 39
Now, we can calculate the sum of the two numbers:
