Hello!</h2>
The answer is: 23.77 hours
<h2>
Why?</h2>
Where:
Total(t) is equal to the amount for a determined time (in hours)
<em>Start</em> is the original amount
<em>t </em>is the time in hours.
For example, it's known from the statement that the bacteria double their population every 15 hours, so it can be written like this:
To calculate how long it takes for the bacteria cells to increase to 300, we should do the following calculation:
So, to know if we are right, let's replace 23.77 h in the equation:
Total(t)=100*2^\frac{23.77}{15}=299.94
and 299.94≅300
Have a nice day!
For c to be positive, and for b to be negative, m must be negative and n must be negative.
X^2 - bx + c = (x - m)(x - n).
c is the product of m and n. If both m and n are positive, c would be positive. However b is the sum of m and n, therefore to make b negative, both m and n must be negative to ensure that the product of m and n is positive
If you have 1/8 in every loaf and 1 teaspoon of nutmeg is 8/8 and you have 4 of those think how much is 8/8 x 4.
Answer:
<u></u>
Explanation:
<u>1. Ratio of campers to counselors in june:</u>
- Ratio = number of campers / number of counselors
- Ratio = 325 campers / 26 counselors
<u />
<u>2. Ratio of campers to counselors in july:</u>
- number of campers = 325 - 265 + 215 = 275
- number of counselors = x (unknown)
<u />
<u>3. Equivalent ratios:</u>
- 325 campers / 26 counselors = 275 campers / x
Solve for x:
- x = (26counselors/325campers) × 275campers = 22 counselors ← answer
