The function representing the number of bacteria after t hours is N(t) = 5300 * (1 + 0.0592)^t, and the growth rate per hour is approximately 5.92%.
To represent the number of bacteria after t hours, we can use the exponential growth formula:
N(t) = N₀ * (1 + r)^t,
where N(t) is the number of bacteria after t hours, N₀ is the initial number of bacteria, r is the hourly growth rate, and t is the time in hours.
In this case, the initial number of bacteria is 5300, and the hourly growth rate can be determined from the doubling time of 12 hours. The growth rate can be calculated using the formula:
r = 2^(1/t_double) - 1,
where t_double is the doubling time in hours.
Substituting the given values, we have:
r = 2^(1/12) - 1 ≈ 0.0592.
Now we can write the function for the number of bacteria after t hours:
N(t) = 5300 * (1 + 0.0592)^t.
To determine the percentage of growth per hour, we can calculate the relative growth rate as a percentage:
percentage_growth = r * 100 ≈ 5.92%.

You should leave at 7:34 to catch the bus that comes at 8:05.
We have,
To catch the bus that arrives at 8:05, you should leave with enough time to reach the bus stop 31 minutes before the bus's arrival time.
To catch the bus that arrives at 8:05, you need to be at the bus stop before the bus arrives. Since it takes you 31 minutes to get to the bus stop, you should leave your starting point early enough to allow for that travel time.
By subtracting 31 minutes from the bus's arrival time of 8:05, you determine the time at which you should depart.
In this case, subtracting 31 minutes gives you 7:34, meaning you should leave at 7:34.
To calculate the departure time, subtract 31 minutes from the bus's arrival time:
= 8:05 - 31 minutes
= 7:34
Thus,
You should leave at 7:34 to catch the bus that comes at 8:05.

Acylinder has a volume of 400 cubic feet. If the height of the cylinder is 25 feet, what is the radius of the cylinder? Use 3.14 for me and round to the nearest hundredth
adius hype your answer...
1
The radius of the cylinder is 2.25 feet.
To find the radius of the cylinder, we can use the formula for the volume of a cylinder:
V = πr²h
Given that the volume V is 400 cubic feet and the height h is 25 feet, we can substitute these values into the formula and solve for the radius r.
400 = 3.14 r² x 25
Dividing both sides of the equation by (3.14 * 25) to isolate r^2, we have:
r² = 400 / (3.14 x 25)
r² ≈ 5.08
Taking the square root of both sides to solve for r, we get:
r ≈ √5.08
r ≈ 2.25
Therefore, the radius of the cylinder is 2.25 feet.

A merchant has 1500 kg of sugar part of which he sells at 8% profit and the rest at 18% profit. He gains 14% on the whole. The quantity sold at 18% profit is
Answer:
900 kg
Step-by-step explanation:
Let's assume the cost price (C.P.) of sugar is Rs. x per kg.
The total quantity of sugar is 1500 kg.
Let the quantity of sugar sold at 8% profit be represented by y kg.
The quantity of sugar sold at 18% profit would then be (1500 - y) kg.
Using the rule of alligation, we can set up the following proportion:
(8% profit) y kg
-------------- = ------
(18% profit) (1500 - y) kg
Simplifying the proportions, we find that the difference in percentages is 4% (18% - 14% = 4%) and 6% (14% - 8% = 6%).
The ratio of these differences is 2:3.
This means that for every 2 kg of sugar sold at 8% profit, 3 kg of sugar is sold at 18% profit.
Since y represents the quantity sold at 8% profit (2 kg), we can calculate the quantity sold at 18% profit (3 kg) as follows:
(2 kg) * (3/2) = 3 kg
Therefore, the quantity sold at 18% profit is 900 kg.
Find the equation of a parabola with focus (3, 4) and directrix y = 1.
The equation of the parabola with focus (3, 4) and directrix y = 1 is [tex]x^2 - 6x - 12y + 57 = 0.[/tex]
To find the equation of a parabola with a given focus and directrix, we can use the standard form of the equation of a parabola:
[tex]4p(y - k) = (x - h)^2[/tex]
where (h, k) represents the coordinates of the vertex, and p is the distance between the vertex and the focus or directrix.
In this case, the focus is given as (3, 4), which means the vertex of the parabola will also be located at (3, 4).
The directrix is given as y = 1.
First, let's find the value of p, which is the distance between the vertex and the focus (or the vertex and the directrix). In this case, p will be the distance between the vertex (3, 4) and the directrix y = 1.
Since the directrix is a horizontal line, the distance between the vertex and the directrix is the vertical distance, which is |4 - 1| = 3.
Now that we have the value of p, we can substitute it into the equation:
[tex]4p(y - k) = (x - h)^2[/tex]
Plugging in the values (h, k) = (3, 4) and p = 3, we get:
[tex]4(3)(y - 4) = (x - 3)^2[/tex]
Simplifying further:
[tex]12(y - 4) = (x - 3)^2[/tex]
Expanding the equation:

Step-by-step explanation:
a. 2r + 5 = b because you have you have 5 more blue marbles than double the red *r= red and b=blue
b. to do the substitution you know that the red marbles plus the blue marbles add up to 77 so
b + r=77
now we can isolate for b and then substitute that value into the first equation
b=77-r and then this goes to 2r+5=77-r
c. now you just have to get like terms to their side of the equal sign
add r to both sides: 2r+r+5=77-r+r= 3r+5=77
and then you subtract 5 from both sides which makes 3r=72
to find r, divide both sides by 3
r=24

a number cube is tossed 60 times Determine the experimental probability of landing on a number less than two
Answer:
1.67% approx
Step-by-step explanation:
To determine the experimental probability of landing on a number less than two when a number cube is tossed 60 times, we need to count the number of times the number on the cube is less than two and divide it by the total number of tosses.
Let's denote the event of landing on a number less than two as "A." We'll count the number of successful outcomes, where the number on the cube is less than two.
Assuming the number cube is fair and unbiased, it has six sides numbered from 1 to 6. Out of these, only one side has a number less than two, which is one.
Now, we can calculate the experimental probability using the formula:
Experimental Probability (P(A)) = Number of successful outcomes / Total number of tosses
In this case, the number of successful outcomes is the number of times the cube lands on a number less than two, which is one. The total number of tosses is given as 60.
Therefore, the experimental probability of landing on a number less than two is:
P(A) = 1 (successful outcomes) / 60 (total number of tosses)
= 1/60
≈ 0.0167 or 1.67%
So, the experimental probability of landing on a number less than two is approximately 0.0167 or 1.67%.

A cheetah's speed was timed over a 50-yard distance. The cheetah was clocked running 60 miles per hour. Write an equation to represent this situation. (If your answering please show how you solved this)
The equation that represents this situation is:
⇒ 60t = 0.0284091
where t is the time in minutes.
We have to given that,
The speed of the cheetah is 60 miles per hour
The distance timed was 50 yards
Now, We have to convert the distance to miles, because the speed is in miles per hour.
Since, 1 yard = 0.000568182 miles
Hence, 50 yards = 50 x 0.000568182 miles
50 yards = 0.0284091 miles
Now we can use the formula:
distance = speed x time
We know that,
The distance is 0.0284091 miles, and the speed is 60 miles per hour.
Hence, the time it took the cheetah to run the 50-yard distance.
So, the speed from miles per hour to miles per minute, since we want the time in minutes:
60 miles per hour = 1 mile per minute
Now we can plug in the values we know:
0.0284091 miles = (1 mile per minute) x time
Solving for time:
time = 0.0284091 / 1
time = 0.0284091 minutes
time = 0.0284091 minutes x 60 seconds per minute
time = 1.704546 seconds
Thus, the equation that represents this situation is:
⇒ 60t = 0.0284091

There are 27 chickens and 13 Rabbits in the pen on your grandmother's farm, based on the given information of 40 heads and 106 legs.
a) The unknowns in the problem are the number of chickens and rabbits in the pen. We don't know the exact quantities of each animal, which is what we need to determine.
b) Let's denote the number of chickens as "C" and the number of rabbits as "R." To represent the total number of animals in the pen, we can write the equation: C + R = total number of animals.
c) The total number of legs can be represented by the equation: 2C + 4R = total number of legs. This equation accounts for the fact that chickens have two legs, while rabbits have four.
d) To find the solution, we can use the given information: 40 heads and 106 legs. Since each animal has one head, the total number of animals is equal to the total number of heads, which is 40.
Using the equation C + R = 40, we can solve for one variable in terms of the other. For example, if we solve for C, we get C = 40 - R.
Substituting this value of C into the equation 2C + 4R = 106, we can solve for R:
2(40 - R) + 4R = 106
80 - 2R + 4R = 106
2R = 26
R = 13
Therefore, there are 13 rabbits in the pen.
To find the number of chickens, we can substitute the value of R into the equation C = 40 - R:
C = 40 - 13
C = 27
Hence, there are 27 chickens in the pen.
In conclusion, there are 27 chickens and 13 rabbits in the pen on your grandmother's farm, based on the given information of 40 heads and 106 legs.

To solve for x, we can cross-multiply:
30 · x = 5 · 24
30x = 120
Dividing both sides of the equation by 30:
x = 120 / 30
x = 4
Therefore, the value of x is 4.
