Answer:
3 pounds
Step-by-step explanation:
1. 50 + 50 = 100
2. 100 / 5 = 20
3. 60 / 20 = 3
Each chicken eats approximately 0.3333 pounds of feed per day, which is calculated by dividing the total feed (100 lbs) by the number of days (60) and then by the number of chickens (5).
To calculate how much chicken feed each chicken eats a day, we need to start by understanding the total amount of feed Ryan bought. He bought two 50 lbs bags, which is a total of 100 lbs of chicken feed. Since the feed needs to last 60 days for 5 chickens, we will divide the total feed by the number of days and then by the number of chickens.
First, we convert the weight of the feed into pounds (if it is not already in pounds). We know there are 100 lbs of feed in total.
Next, we divide the total weight of the feed by the number of days to find out how much feed is used per day:
100 lbs / 60 days = 1.6667 lbs per day (for all 5 chickens together).
Finally, we divide the daily feed consumption by the number of chickens to find out how much each chicken eats per day:
1.6667 lbs per day / 5 chickens = 0.3333 lbs per chicken per day.
Therefore, each chicken eats approximately 0.3333 pounds of feed a day.

Find the area of a circle with a diameter of 6.
Either enter an exact answer in terms of pi or use 3.14 for pi and enter your answer as a decimal.
To find the area of a circle with a diameter of 6, divide the diameter by 2 to get the radius, then use the formula Area = πr² with the calculated radius, resulting in an area of 28.26.
Using either the exact value of π (pi) or its approximation 3.14, we substitute the radius into the formula to calculate the area.
Using π, the area is:
A = π(3)² = 9π
Using the approximation of 3.14 for π, the area is:
A = 3.14(3)² = 3.14(9) = 28.26
So, the area of the circle is either 9π square units or approximately 28.26 square units if you use 3.14 for π.

A cylinder has a radius of 24.6 inches and a volume of 29,468 in3. Find its height.
A. 14.5 in
B. 15 in
C.15.5 in
D. 16.5 in
Answer:
15.49 inches
Step-by-step explanation:
Volume of a cylinder is given by
[tex]V=\pi r^{2}h[/tex]
Making h the subject of the formula then
[tex]h=\frac {V}{\pi r^{2}}[/tex]
Where h is the height, V is volume and r is radius. Substituting 24.6 inches for r and 29468 cubic inches for V then
[tex]h=\frac {29468}{\pi 24.6^{2}}=15.493723673378\ in\approx 15.49\ in[/tex]
Therefore, the height is approximately 15.49 inches
The correct height of the cylinder that produces a volume of 29,468 in3 is 15 inches (Choice B).
To find the height of a cylinder with a volume of 29,468 cubic inches (in3) and a radius of 24.6 inches, we use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height.
Plugging in the known values, we get:
29,468 in3 = π(24.6 in)2h
Solving for h, the height of the cylinder, we perform the following steps:
Calculate the base area: Base Area = π(24.6 in)2
Divide the volume by the base area to find the height: h = Volume / Base Area
Calculate the height: h = 29,468 in3 / (π(24.6 in)2)
After performing the calculation, we conclude that the correct height of the cylinder that produces a volume of 29,468 in3 is 15 inches (Choice B).

using the numbers 0-6 once, make 2 equivalent ratios
Step-by-step explanation:
As we have to use the number 0-6 once to make 2 equivalent ratios.
so lets solve the problem.
Determining first equivalent ratio
as
5 times 2 = 10and
32 times 2 = 64so
Together will get 10/64Therefore, first equivalent ratio
[tex]\:\frac{5}{32}=\frac{10}{64}[/tex]
Determining second equivalent ratio
[tex]\frac{13}{65}=\frac{4}{20}[/tex]
as
[tex]\frac{13}{65}=\frac{1}{5}[/tex]
and
[tex]\frac{4}{20}=\frac{1}{5}[/tex]
Therefore, second equivalent ratio
[tex]\frac{13}{65}=\frac{4}{20}[/tex]
Both can be simplified to 1:2.
To create two equivalent ratios using the numbers 0-6 once, we first need to understand that a ratio compares two quantities and equivalent ratios can be simplified or expanded from one another by the same factor. Here, we select the numbers carefully to form such ratios.
Let's use the numbers 2, 3, 4, and 6. The ratio of 2:4 is equivalent to 3:6 because when both sides of the first ratio are multiplied by 2, the result is the second ratio. Therefore, the ratios 2:4 and 3:6 are equivalent because they express the same relationship between numbers, as both can be simplified to the ratio of 1:2.

Answer:
$135.92
Step-by-step explanation:
Just chose Bedroom 3 because it has whole numbers, none of the other rubbish.
The interior surface area of the bedroom can be calculated by the formula:
2lw + 2wh + 2lh
The surface area is 816 feet squared.
Since we are painting the room twice, we can just double this value for the sake of the next step.
The cost per gallon of paint is $33.98.
Each gallon covers 400 ft^2.
The number of gallons required is (816*2)/400, which is 4.08 gallons. If we approximate that we require 4 gallons, then the total cost will be $33.98*4 = $135.92.

and dimes. Who am I?
What is the answer
Answer:
6 coins
Step-by-step explanation:
3 dimes
1 nickel
2 pennies
Answer: 6 coins
Step-by-step explanation:
Pennies = 1c
Nickels = 5c
Dimes = 10c
10 * 3 dimes = 30c
30c + 5c (a nickle) = 35c
35c + 2 pennies = 34
Therefore, the lowest amount of coins is 6 (3 dimes, 1 nickle, and 2 pennies)

There are 300 bunnies on a bunny farm. The farmer says their population
increases at a rate of 20% per year. What is the INITIAL VALUE for this
equation?
Answer:
The initial value is 300 bunnies
Step-by-step explanation:
we know that
The equation of a exponention growth function is given by
[tex]y=a(1+r)^x[/tex]
where
y is population of a bunnies
x is the number of years
a is the initial value
r is the rate of change
we have
[tex]a=300\\r=20\%=20/100=0.20[/tex]
substitute
[tex]y=300(1+0.20)^x[/tex]
[tex]y=300(1.20)^x[/tex]
therefore
The initial value is 300 bunnies

When solving the following system by elimination, which variable would be eliminated after adding the 2 equations together?
Answer:
B. x
Step-by-step explanation:
-3x+8y=-6
3x-2y=-12
if we add these
-3x+3x+8y-2y=-6-12
6y=-12 so x will be eliminated
Final answer:
When solving a system by elimination, the variable eliminated is the one with coefficients that add up to zero when equations are combined.
Explanation:
When solving the following system by elimination, which variable would be eliminated after adding the 2 equations together?
When adding the two equations together in a system, the variable that will be eliminated will be the one that has coefficients with additive inverse values. For example, if one equation has x and the other has -x, adding them would result in the elimination of the x variable.
After adding the two equations together, look for a pair of variables that will cancel each other out, resulting in the elimination of one variable.
What is 54 in scientific notation
Answer:
5.2 times 10^1
Step-by-step explanation:
the first number should be less than ten.
Answer: [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex]
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
So here, we have 5.4 and notice that there
is only one digit to the left of the decimal point.
Next, we count the number of places the decimal point would
need to move to get back to the original number, 54.
Since we would need to move the decimal point 1 place to the right,
we have an exponent of positive 1.
Now, scientific notation is always expressed as a number between 1 and 10 including 1 but not 10 and it is multiplied by 10 to a certain power that must be an integer.
So we have [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex]
Notice that the exponent is positive.
This is because we would need to move the decimal point to the right in order to get back to the original number.
So 54 can be written in
scientific notation as [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex].
Liam is making barbecue ribs over a fire. The internal temperature of the ribs when he starts cooking is 40°F. During each hour of cooking, the internal temperature will increase by 25%. The ribs are safe to eat when they reach 165°F.
Use the drop-down menus to complete an inequality that can be solved to find how much time, t, it will take for the internal temperature to reach at least 165°F.
Answer: You need to wait at least 6.4 hours to eat the ribs.
t ≥ 6.4 hours.
Step-by-step explanation:
The initial temperature is 40°F, and it increases by 25% each hour.
This means that during hour 0 the temperature is 40° F
after the first hour, at h = 1h we have an increase of 25%, this means that the new temperature is:
T = 40° F + 0.25*40° F = 1.25*40° F
after another hour we have another increase of 25%, the temperature now is:
T = (1.25*40° F) + 0.25*(1.25*40° F) = (40° F)*(1.25)^2
Now, we can model the temperature at the hour h as:
T(h) = (40°f)*1.25^h
now we want to find the number of hours needed to get the temperature equal to 165°F. which is the minimum temperature that the ribs need to reach in order to be safe to eaten.
So we have:
(40°f)*1.25^h = 165° F
1.25^h = 165/40 = 4.125
h = ln(4.125)/ln(1.25) = 6.4 hours.
then the inequality is:
t ≥ 6.4 hours.
Answer:
40 × 1.25 ^ t greater or equal to ( >) 165
