area: about
in. 2
Answer:
50.24 in.
Step-by-step explanation:
Step 1: Define/explain/formula.
To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.
Definitions:
The diameter is the length through the center.The radius is half of the diameter.The area of a circle is the amount of interior space enclosed by a circle.The circumference of a circle is the distance around the circle.'π' means pi.[tex]a=\pi r^2(3.14*radius*radius)[/tex]
Step 2: Solve.
The radius of this circle is 4.
Now, we simply plug the numbers into the formula.

Work out the interior angle of the octagon.
Please show the working out.
Answer:
135°
Step-by-step explanation:
formula = (n-2) * 180, whereby 'n' is the number of sides.
therefore, (8-2) * 180 = 1080°
1080° ÷ number of sides
= 1080° ÷ 8
= 135°
Answer:
∠a = 135°
Step-by-step explanation:
There is a formula for finding the sum of the interior angles of any polygon.
N = number of sides
sum of interior angles = (180° x N) - 360°
so:
(180° x 8) - 360° = 1080°
1080°/8 angles = 135° each angle
How can these models be used to find the sum 2. 3 + 1. 94?
Enter your answers in the boxes.
The models show a total of 3 wholes,
tenths, and
hundredths. After regrouping 10 tenths into 1 whole, there are
wholes,
tenths, and
hundredths. Therefore, the sum of the numbers is
The sum of 2.3 and 1.94, that is 2.3 + 1.94 is 4 wholes, 2 tenths and 4 hundredths, which can be written in decimal form as 4.24.
Therefore the answer is 4.24.
The first number, 2.3, can be broken down into 2 wholes and 3 tenths.
The second number, 1.94, can be broken down into 1 whole, 9 tenths and 4 hundredths.
To add the two numbers together, we first add the wholes: 2 + 1 = 3.
Next, we add the tenths: 3 + 9 = 12
Since we cannot have more than 9 tenths in a whole, we must regroup 12 tenths as 1 whole and 2 tenths.
We add the regrouped tenths to the number of wholes: 3 + 1 = 4
After regrouping, we have 4 whole and 2 tenths.
Now we add the hundredths: 0 + 4 = 4
Thus the sum is 4 wholes, 2 tenths and 4 hundredths, which can be written in decimal form as 4.24.

Is 9x² 24x 16 a perfect square trinomial?
9x² + 24x + 16, which is the full quadratic trinomial expressed as (3x +4)².
What is a trinomial expression?A trinomial expression is an algebraic expression containing three distinct terms, hence the name "trinomial expression". An algebraic expression called a trinomial expression contains three nonzero terms. A trinomial expression is formed when three monomials are added or subtracted from each other. A quadratic trinomial has the form: ax² + bx + c, where a, b, and c are nonzero real values.
Given that
9x² + 24x + 16
= (3x)² + 2(12x) + 16
= (3x)² + 2(3x)(4) + 4²
This is similar to a² + 2ab + b² = (a + b)².
So you can write:
= (3x + 4)²
= (3x +4) (3x + 4)
So this is a complete quadratic trinomial.

What is circle?Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. At every angle, it is also rotationally symmetric about the center. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.

How do you make a graph compare two sets of data?
There are several ways to make a graph to compare two sets of data, but one common method is to use a line graph.
The steps to create a line graph to compare two sets of data:
Organize the data: Arrange the data into two columns, one for each set of data. Each column should have a label at the top to indicate what the data represents.
Choose a scale: Decide on an appropriate scale for the x- and y-axes that will allow you to clearly display the data. The x-axis should represent the categories being compared, and the y-axis should represent the values of the data.
Plot the data: Using the chosen scale, plot the data points for each set of data on the graph. Use different colors or symbols for each set of data to make it easy to distinguish between the two.
Add a title: Give the graph a title that describes what the graph is showing.
Add a legend: Add a legend to the graph to indicate what each set of data represents.
Add labels: Label the x- and y-axes to indicate what they represent.
By following these steps, you can create a clear and informative line graph that allows you to easily compare two sets of data.
Other types of graph that can be used to compare two sets of data are bar charts, scatter plots, and stacked bar charts. The choice of graph depends on the type of data you have, and what you want to compare or highlight.

Answer:
7/15
Step-by-step explanation:
number of favorable outcomes (red jelly beans) = 7
number of total outcomes (total jelly beans) = 7 + 2 + 6 = 15
probability of red = number of favorable outcomes/number of total outcomes = 7/15
The probability of getting a red jelly bean is 7/15
Total number of jelly beans in the jar (sum of all the jelly beans): 7+6+2= 15

Step-by-step explanation:
parallelograms and relatively even shapes, so how ever far apart the bottom two vertices are apart is how far apart you would space the top ones. simply add the x coordinates absolute values (meaning ignore negative values for now) 6+0=0. 6 Units away from 3( top vertex is (3,7)) would be -3. for the y coordinates you gotta look at y coordinates of the top vertex and bottom right vertex. they're ten units apart. go ten up from -5( because the bottom left vertex is (-6,-5) and you get 5. so overall (-3,5) would be the last vertex
Answer:
(-3,5)
Step-by-step explanation:
Since parallelograms are relatively even shapes, the distance between the bottom two vertices determines the distance between the top two. Simply add the absolute values of the x coordinates (meaning ignore negative values for now) 6 + 0 = 0 -3 is 6 units away from 3 (top vertex is (3,7)). Look at the y coordinates of the top vertex and bottom right vertex for the y coordinates. They're separated by ten units. Since the bottom left vertex is (-6,-5) and you get 5, go ten up from -5.

Find the solutions of the quadratic equation 3x2−x+8=03x 2 −x+8=03, x, squared, minus, x, plus, 8, equals, 0.
The solutions of the quadratic equation 3x² − x + 8 = 0 are as follows;
x = 0.1667 + 1.6245i
x = 0.1667 - 1.6245i
How to solve the given quadratic equation?In Mathematics, the standard form of a quadratic equation is given by this mathematical expression;
ax² + bx + c = 0
Mathematically, the quadratic formula is modeled or represented by this mathematical expression:
[tex]x = \frac{-b\; \pm \;\sqrt{b^2 - 4ac}}{2a}[/tex]
From the information provided above, we can logically deduce the following data values (parameters);
3x² − x + 8 = 0
Where:
a = 3b = -1c = 8Substituting the data values (parameters) into the quadratic formula, we have the following;
[tex]x = \frac{-(-1)\; \pm \;\sqrt{(-1)^2 - 4(3)(8)}}{2(3)}\\\\x = \frac{1\; \pm \;\sqrt{1\; - \;4(3)(8)}}{2(3)}\\\\x = \frac{1\; \pm \;\sqrt{1\; - \;96}}{6}[/tex]
