Find the perimeter of the figure to the nearest hundredth.
The perimeter of the circular figure is P = 36.85 feet
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
Given data ,
Let the perimeter of the figure be represented as P
Now , the perimeter of the figure P = perimeter of circle + perimeter of lengths of sides
The total lengths of sides = ( 3 + 3 + 3 + 3 + 3 + 3 ) feet
The total lengths of sides = 18 feet
And , the circumference of circle = 2πr
The diameter of the circle d = 12 feet - 6 feet
The diameter of the circle d = 6 feet
So , the radius of the circle r = d/2 = 3 feet
And , the circumference of circle = 2 x π x 3
The circumference of circle = 6π
So , perimeter of the figure P = ( 6π + 18 ) feet
Perimeter of the figure P = 36.849 feet
Hence , the perimeter of the figure is 36.85 feet

of the total budget on equipment. What was the total budget for their
student film?
As a result, their student film's overall budget was $1200, with $192 spent on props and 68% of the budget allocated to equipment.
what is percentage ?A number or ratio that is expressed as a fraction of 100 is known as a percentage in mathematics. There are also sporadic uses of the acronyms "pct.," "pct," and "pc." However, the percent sign "%" is widely used to signify it. There are no dimensions to the percentage amount. Percentages are essentially fractions because they have a numerator of 100. Put the percent sign (%) next to a number to indicate that it is a percentage. For instance, you would score a 75% if you answered 75 out of 100 questions on a test correctly (75/100). Divide the money by the total to get percentages, then multiply the result by 100. The formula (value/total) x 100% is used to determine the percentage.
given
On a student movie, some pals were engaged.
On props and equipment, they used the entire budget.
A total of $24% of the budget was spent on equipment, or $912, on props.
Let's write down the movie's overall budget as x.
$870 was spent on the equipment.
The props budget is equal to 24% of x.
Equipment costs plus prop costs equal the total budget.
x = 912 + 24% of x
x = 912 + 0.24x
x - 0.24x = 912
0.76x = 912
x= 912/0.76
x = $1200
As a result, their student film's overall budget was $1200, with $192 spent on props and 68% of the budget allocated to equipment.

You have been asked to find the value of f(-5) for the function
f(x)=3x² -2x+5
Which of the following options is NOT a possible way to evaluate that function and find the correct answer?
A. Graph the equation and look at the table to find the y-value when x=-5
B. Graph the equation and find the y-value of the ordered pair when x=-5
C. Substitute (-5) wherever there is an x and solve using a calculator
D. See what x is when y=-5
Answer: D option is not the correct way to evaluate.
Step-by-step explanation: To find out f(x) which is also known as y.
so, f(x) = 3x^{2} - 2x + 5
f(-5) = 3 × 25 - 2(-5) + 5
= 75 + 10 + 5
= 90
Here we see here that four alternatives are given to find out but the option D is not appropriate.
A. By drawing a graph one can easily find out the value here we will try to find out the graph line and then by drawing it on the graph.
B. Similar to option A we can find out using option B
C. I had also used the same method to calculate for the value of (-5) above so this option is also correct.
D. When y= -5 then if we find out it for x will not work as here we have to find out f(x) which is function of X i.e. simply Y. so this won't work.
The following option is not a possible way to evaluate that function:
See what x is when y=-5.
The correct option is D.

The required measure of angle m∠3 = 60° for the given figure.
What is the interior Angle?An interior angle is defined as an angle produced on the inside of a polygon by extending the sides of the polygon.
As per the interior angle property, we have
40° + 85° + m∠1 = 180°
m∠1 = 180° - 40° - 85°
m∠1 = 55°
Since m∠1 = m∠2 (opposite angles)
m∠2 + m∠3 + 55° = 180°
55° + m∠3 + 55° = 180°
m∠3 = 180° - 55° - 55°
m∠3 = 60°

What does it mean to say that the difference in proportions is "significant"?
When comparing the means of two groups and their relationships, a t-test is an inferential statistic used to assess whether there is a significant difference.
Is the difference between two proportions significant? T-tests are employed when data sets, such as the one resulting from tossing a coin 100 times, have normal distributions and unknown variances.Like comparing two means, comparing two proportions is a popular practise. Two estimated proportions that differ from one another could be the result of chance or a discrepancy in the populations. If there is a disparity between the estimated proportions and the population proportions, the hypothesis test can help to clarify this.Start by locating your variance on the left side of your degrees of freedom. Next, move up to view the p-values. Comparing the p-value and alpha can help you determine the significance level.

pound of chocolate equally?
Each person will receive two ounces of chocolate.
What is equality?Equality in math is a concept that states that two values, expressions, or quantities are the same. It is symbolized by the equal sign "=" and is used to express that two values are equivalent. Equality is an important concept in math and is used in solving equations, simplifying expressions, and comparing different numbers. Equality can also be used to show that two quantities are balanced, such as in the equation x+7=10. Equality is a fundamental principle of mathematics that is used in many different areas.
If four people share one-third of a pound of chocolate equally, each person will receive approximately two ounces of chocolate. This can be calculated by dividing the total amount of chocolate (one-third of a pound) by the number of people (four), which gives 0.375 pounds per person. Since there are 16 ounces in a pound, 0.375 pounds is equal to six ounces. Since two of those ounces are not divisible into equal portions, each person will receive two ounces of chocolate.

A quadrilateral is a four-sided polygon, and it can come in various shapes and forms such as square, rectangle, rhombus, parallelogram, etc.
Explain about angles of polygon quadrilateral:Each type of quadrilateral has its own unique characteristics and properties. A rhombus has all its sides equal in length, and a parallelogram has opposite sides parallel to each other. The sum of all interior angles of a quadrilateral is always 360 degree which is a common property for all types of quadrilaterals.A quadrilateral is a four-sided polygon and its interior angles can be calculated using the formula (n-2) * 180 / n where n is the number of sides. In the case of a quadrilateral, n=4. The formula becomes (4-2)*180/4 = 90 degree. Therefore, the measure of each interior angle in a quadrilateral is 90 degrees. This is true for any convex quadrilateral. But when a quadrilateral has one angle less than 90 degree, it becomes concave and no longer follows this rule. In other words, not all quadrilaterals will have interior angles that measure 90 degrees each. It's important to note that, the sum of all interior angles of a quadrilateral is always 360 degree.To find the value of x (the measure of an interior angle in a quadrilateral) using the formula (n-2) * 180 / n, you need to know that a quadrilateral has 4 sides (n = 4).
Given that the interior angle is 69, we can substitute n = 4 into the formula:
x = (4-2) * 180 / 4
This simplifies to:
x = (2) * 180 / 4
x = 90
Therefore, the measure of an interior angle in a quadrilateral is 90 degrees. Since you have given one of the angle as 69 degree, we can say that the quadrilateral is not a convex quadrilateral.
