A factory made 886 jars of peanut butter. 443 of the jars contained creamy peanut butter. What percentage of the jars of peanut butter was creamy?
Answers
Answer:
50%
Step-by-step explanation:
To find the percentage, we need to divide the amount of creamy peanut butter by the total amount of peanut butter. In this case, there are 443 jars with creamy peanut butter and 886 total jars.
What is 443/886? Well, you could divide it out, but you could also notice that 443 is exactly half of 886 and simplify to 1/2, which is equal to 0.5. Either way works, but one's just a lot quicker.
Next, we have to convert the decimal - 0.5 - into a percentage. To do this, we move the decimal point to the right two spots, getting us to 50, and then slap a percentage sign on there giving us a final answer of 50%.
Hopefully that's helpful! :)

Answers
It's worth noting that some people might consider a month to be complete after a certain number of days have passed, such as 30 days or 31 days.
What is the time and date calculations?
Time and date calculations involve mathematical operations to determine the difference between two dates, calculate the number of days, weeks, months, or years between two dates, and perform other similar operations with dates and times.
To calculate the 9th month from the date that you got back together with someone on January 30th, we need to consider the fact that not all months have 30 days and that February has 28 days in a non-leap year.
One method to keep track of the months would be to use the calendar to add the number of months to the starting date and adjust for any changes in the year or the month.
Starting from January 30th, we add 8 months to get September 30th. Adding one more month will take us to October 30th, which is the 9th month from the starting date.
It's worth noting that some people might consider a month to be complete after a certain number of days have passed, such as 30 days or 31 days. But, this can vary and might not always align with the calendar.

1. The rate at which people enter a movie theater on a given day is modeled by the function S defined by S(t) = 80-12cos The rate at which people leave the same movie theater is modeled by the function R 7 5 defined by R(t) = 12e/o +20. Both S(1) and R(1) are measured in people per hour and these functions are valid for 10(Solved A, but need the explanations for B to D)
Answers
The given rates indicates the number of people that enter or leave the
theater in a unit time.
Responses (approximate values):
a. 899 people
b. 139 people
c. Approximately 20 people are leaving per unit time at t = 20
d. The number of people in the theater are is a maximum at t ≈ 17.776
How is a function integrated, and what is rate of change?\(S(t) = \mathbf{80 - 12 \cdot cos \left(\dfrac{t}{5} \right)}\)
\(R(t) = \mathbf{12 \cdot e^{t/10} + 20}\)
a. The number of people that have entered the movie theater at t = 20
seconds given to the nearest whole number (by rounding down) are as
follows;
\(\displaystyle \mathbf{\int\limits^{20}_{10} 80 - 12 \cdot cos \left(\dfrac{t}{5} \right) \, dt }= 899\pi\)
899 people have entered at t = 20b. The number of people in the theater, at time, t, P(t) given to the nearest whole number at t = 20 are found as follows;
\(Number \ in \ the \ theater, \ P(t) = \displaystyle \mathbf{\int\limits^{t}_{10} \left( S(t) - R(t) \right)\, dt}\)
Which gives;
\(\displaystyle P(20) = \mathbf{\int\limits^{20}_{10} \left(80 - 12 \cdot cos \left(\dfrac{t}{5} \right) \right) - \left(12 \cdot e^{t/10} + 20 \right) dt} \approx 139\)
There are approximately 139 people in the theater at t = 20c. The value of P'(t), is found as follows;
\(P(t) = \displaystyle \mathbf{\int\limits^{t}_{10} \left( S(t) - R(t) \right)\, dt}\)
Therefore;
\(\displaystyle P(t) = \mathbf{ \int\limits^{t}_{10} \left(80 - 12 \cdot cos \left(\dfrac{t}{5} \right) \right) - \left(12 \cdot e^{t/10} + 20 \right) dt}\)
Which gives;
\(P(20) = \left(60 \cdot sin(2) + 120 \cdot e + 60 \cdot t - 600\right) - 120 \cdot e^{\dfrac{t}{10} } + 60 \cdot sin \left(\dfrac{t}{5} \right)\)
By differentiation, we have;
\(P'(t) = \mathbf{ -\left(120 \cdot e^{\dfrac{t}{10} } \cdot \dfrac{10}{100} +60 \cdot cos \left(\dfrac{t}{5} \right) \cdot \dfrac{5}{25} -60 \right)}\)
Which gives;
\(P'(20) = -\left(120 \cdot e^{\dfrac{20}{10} } \cdot \dfrac{10}{100} +60 \cdot cos \left(\dfrac{20}{5} \right) \cdot \dfrac{5}{25} -60 \right) \approx -20.825\)
P'(20) indicates that at t = 20, approximately 20 people are leaving the movie theater per unit timed. The time at which the maximum number of people are in the theater is given as follows;
At the maximum number in the theater, P'(t) = 0
Therefore;
\(P'(t) =0 = \mathbf{-\left(120 \cdot e^{\dfrac{t}{10} } \cdot \dfrac{10}{100} +60 \cdot cos \left(\dfrac{t}{5} \right) \cdot \dfrac{5}{25} -60 \right)}\)
Which gives;
\(\mathbf{120 \cdot e^{\dfrac{t}{10} } \cdot \dfrac{10}{100} +60 \cdot cos \left(\dfrac{t}{5} \right) \cdot \dfrac{5}{25}} = 60\)

Answers
Given the graph of f(x) and the function:
\(g(x)=-2(x+5)^2+3\)You need to remember that, by definition, the Axis of Symmetry of a parabola passes through its vertex, and divides the parabola into two equal parts.
• You can identify in the graph that the vertex of the parabola is its maximum point:
\((5,3)\)Therefore, you can draw the vertical lines that pass through the vertex:
Notice that the x-coordinate of each point on the line is always the x-coordinate of the vertex of the parabola. Therefore, the equation for that line is:
\(x=5\)• In order to find the Axis of Symmetry of g(x), you need to rewrite it in this form:
\(g(x)=ax^2+bx+c\)By definition:
\((a+b)^2=a^2+2ab+b^2\)Therefore, you can expand the function:
\(g(x)=-2(x^2+2(x)(5)+5^2)+3\)\(g(x)=-2(x^2+10x+25)+3\)\(g(x)=-2x^2-20x-50+3\)\(g(x)=-2x^2-20x-47\)Now you can find the Axis of Symmetry using this formula:
\(x=-\frac{b}{2a}\)In this case:
\(\begin{gathered} a=-2 \\ b=-20 \end{gathered}\)Then, you get:
\(\begin{gathered} x=-\frac{(-20)}{2(-2)} \\ \\ x=-5 \end{gathered}\)Hence, the answer is: Option B.

\(r = \frac{1}{2} * 23\)
\(r = 11.5\)
Substitute 11.5 for r in \(V = \frac{4}{3}\pi r^3\)
\(V = \frac{4}{3} * \frac{22}{7} * 11.5^3\)

The graph of the function f(x) = –(x + 6)(x + 2) is shown below.
On a coordinate plane, a parabola opens down. It goes through (negative 6, 0), has a vertex at (negative 4, 4), and goes through (negative 2, 0).
Which statement about the function is true?
The function is increasing for all real values of x where
x < –4.
The function is increasing for all real values of x where
–6 < x < –2.
The function is decreasing for all real values of x where
x < –6 and where x > –2.
The function is decreasing for all real values of x where
x < –4.
Answers
The statement about the function is: "The function is decreasing for all real values of x where x < -4." D.
The given information tells us that the graph represents a downward-opening parabola.
The vertex of the parabola is located at (-4, 4) indicates that this point is the highest point on the graph.
As we move to the left of the vertex, the function values decrease, indicating a decreasing trend.
Moreover, the graph passes through the point (-6, 0), which lies to the left of the vertex.
This confirms that the function is decreasing for all real values of x less than -4, including x < -6.
On the other hand, the graph also passes through the point (-2, 0), which lies to the right of the vertex.
This does not impact the conclusion that the function is decreasing for x < -4, as the graph's behavior to the right of the vertex is not relevant to this particular statement.
Based on the given information and the properties of the downward-opening parabola, we can conclude that the function is decreasing for all real values of x where x < -4.

and then drops 9 degrees between 8 am and 9 am, find the temperature at 9 am
Answers
Answer:
-24degC
Step-by-step explanation:
-6degC dropping by 2degC leads to -8degC (2degC colder, higher value negative numbers are colder as negative numbers increase in the opposite direction of positives)
so next -8degC rising by 3degC which is 3degC hotter(less negative) will give -5degC
the finap drop by 9degC makes the final temperature -5 -19 = -24degC(similar reasoning)
if you want a more straightforward method to doing these sorts of questions, just take temperature rise : add the value it rose by and temperature fall/drop: subtract the value it dropped/falled by.
-8 + 3 = -5
-5 - 9 = -14
the temperature at 9am would be -14°C .
