Answer: x = (5√2)/2
The last option
Explanation:
The given triangle is a right triangle. Taking angle 45 as the reference angle,
hypotenuse = 5
opposite side = x
We would find x by applying the sine trigonometric ratio which is expressed as
sin θ = opposite side/hypotenuse
By substituting the given values into the equation,
sin45 = x/5
Recall,
[tex]sin45\text{ = }\frac{\sqrt{2}}{2}[/tex]Thus,
[tex]\begin{gathered} \frac{\sqrt{2}}{2}\text{ = }\frac{x}{5} \\ By\text{ crossmultiplying,} \\ x\text{ = }\frac{5\sqrt{2}}{2} \end{gathered}[/tex]x = (5√2)/2

The average rate of change of the function is found as 1.
What is termed as the rate of change of function?The rate of change function has been described as the rate during which one quantity changes in relation to another. The rate of change from y coordinates to x coordinates can be calculated as Δy/ Δx = (y2 - y1)/ (x2 - x1 ).For the given question;
The function is given by the equation;
g(x) = -x² - 9x + 27
The interval of the function lies as;
-9 ≤ x ≤ -1.
Let,
a = -1 ans b = -9
Then,
g(a) = g(-1), Put x = -1 in the function.
g(-1) = -(-1)² - 9(-1) + 27
g(-1) = 35
Now, g(b) = g(-9), Put x = -9 in the function.
g(-9) = -(-9)² - 9(-9) + 27
g(-9) = 27
Thus, the average rate of change of the function is-
Average rate of change = [g(a) - g(b)]/[a - b]
= [35 - 27]/[-1 + 9]
= 8/8
= 1
Thus, the average rate of change of the function is found as 1.

If OA-OB-OC and if AOB = 9x + 20, BOC = 7x - 6 and AOC = 142 find BOC
Answers
The angle BOC has a measure of 50 degrees
How to evaluate the measure of the angle?From the question, the given parameters about the angles are:
OA-OB-OCAOB = 9x + 20BOC = 7x - 6AOC = 142The above parameters implies that
AOC = AOB + BOC
Next, we substitute the angle measurements in the above equation
So, we have
142 = 9x + 20 + 7x - 6
Evaluate the like terms
So, we have the following equation
142 = 16x + 14
Evaluate the like terms again
So, we have the following equation
16x = 128
Divide both sides by 16
x = 8
Substitute x = 8 in BOC = 7x - 6
BOC = 7 x 8 - 6
Evaluate
BOC = 50

What is Angle?An angle is formed when two straight lines or rays meet at a common endpoint
If OA-OB-OC and if AOB = 9x + 20, BOC = 7x - 6 and AOC = 142
We need to find BOC
We have AOC = AOB + BOC
142=9x + 20+7x-6
142=16x+14
Subtract 14 from both sides
142-14=16x
128=16x
Divide both sides by 16.
8=x
Now put x value in BOC = 7x - 6
BOC = 7x - 6

Write an inequality that would represent the possible values for the number of cupcakes purchased, c, and the number of brownies purchased, b.
Answers
The inequality equation is 3c + 2.25b <=15 which represents the possible values of cupcakes and brownies that can be purchased by Aisha with the given amount of money.
Cost of each cupcake = $3
Cost of each brownie = $2.25
Total money available with Aisha to spend on cupcakes and brownies = $15
Let c represent the number of cupcakes purchased by Aisha and b represent the number of brownies purchased by Aisha
Formulating the inequality equation we get the following:
Cost of each cupcake*Number of cupcakes purchased + Cost of each brownie*Number of brownies purchased <= Total money available with Aisha

What’s the slope I need help
Answers
Answer:
-8/3
Step-by-step explanation:
You want the slope of the line shown in the graph.
Slope from point coordinatesWhether counting grid squares on the graph, or using the slope formula, it is convenient to choose two points on the grid where the line crosses the intersection of grid lines.
It appears, the line passes through grid points (1, 4) and (4, -4). Using the slope formula, we find the slope of the line to be ...
m = (y2 -y1)/(x2 -x1)
m = (-4 -4)/(4 -1) = -8/3
The slope of the line is -8/3.
Counting grid squaresThe slope is the ratio of "rise" to "run" for the line. From the two points we see where the line crosses grid intersections, we have a "rise" of -1 from y=4 to y=-4, and a "run" of 3 from x=1 to x=4.
rise/run = -8/3 = slope of the line

Congruent is what?When two figures or objects in geometry have the same shapes, sizes, or are mirror images of one another, they are said to be congruent.
Formally, two sets of points are said to be congruent if, and only if, an isometry, which is a collection of rigid motions including translation, rotation, and reflection, can transform them into one another.
This shows that resizing an object will not allow it to be properly aligned with another object, only by moving and reflecting it. Therefore, two independent plane figures on a piece of paper are congruent if we can cut them out and then precisely line them up. The paper might be distributed.
Each box is the same size in terms of length and width. The only change is where the figure is located.
Transformations can be divided into four categories: translation, rotation, reflection, and dilation.
Two figures are said to be "congruent" if they can be positioned perfectly over one another. Congruent refers to things that are exactly the same size and shape.

The expression which correctly represents the amount of candy sold each year per type at Cassandra's Candy corner is; 2x2 – 4x + 54.
Polynomial divisionIt follows from the task content that the expression which shows the amount of candy sold each year per type is to be determined.
Since, the function, C (x) = 4x³ + 16x² + 60x + 648 represents the total amount of candy sold while, T(x) = 2x + 12 represents the amounts of types of candy.
Therefore, the amount of candy sold each year per type is; C(x) ÷ T(x).
Hence, the result of the polynomial division as in the attached image is; 2x² - 4x + 54.
Ultimately, the amount of candy sold each year per candy is represented by the expression; 2x² - 4x + 54.

We have the fraction 6/10
For finding the equivalent number, we divide 6 by 10:
6 / 10 = 0.6
0.6 is the equivalent number
We have 6 in the numerator and 10 in the denominator, if we calculate any mathematical operation to both, we will find the equivalent fractions.
Let's see two examples:
1. Let's divide by 2:
6 divided by 2 is 3; and 10 divided by 2 is 5. Then our new equivalent fraction is
[tex]\frac{3}{5}[/tex]2. Let's multiply by 3:
6 multiplied by 3 is 18; 10 multiplied by 3 is 30. Then a second equivalent fraction is:
[tex]\frac{18}{30}[/tex]We can calculate additional equivalent fractions, using the same operation for both: numerator and denominator.
For calculating the equivalent fraction in hundreds, we will use the initial decimal equivalent we calculated at the beginning: 0.6
0.6 = 6/10 and we multiply it by 10 numerator and denominator
6 * 10 = 60 and 10 * 10 = 100. Then the fraction is 60/100
20 divided by 10 is 2 and 100 divided by 10 is 10, so the equivalent fraction is 2/10
This case is exactly the same than the previous we solved:
?/10 = 120/100
As you can see the first fraction is notated in tens and the second is notated in hundreds. Therefore, if you divide 120 between 10, what is the result?

parallelogram ABCD is below. m < D = 130° and m < B = (3x-1.5)° . solve for x and round to the nearest whole number.
Answers
Given:
m∠D = 130 degrees
m∠B = (3x - 1.5) degrees
Let's solve for the value of x.
A parallelogram is a quadilateral that has equal opposite angles and equal opposite sides.
Since a parallelogram has equal opposite angles, measure of angle D and measure of angle B are equal.
Thus, we have the equation:
m∠B = m∠D
(3x - 1.5) = 130
Solve for x.
Remove the parentheses:
3x - 1.5 = 130
Add 1.5 to both sides:
3x - 1.5 + 1.5 = 130 + 1.5
3x + 0 = 131.5
3x = 131.5
Divide both sides by 3:

What is Surface area?A solid object's surface area can be stated as a measurement of the overall space that the object's surface takes up. As an alternate, surface area can also be described as the area of the entire outer part, or which is said as the uppermost layer of any kind of 3D object.
Square units are used in the calculation. The total area of all the outside surfaces makes up the surface area of a three-dimensional object, which is also expressed in square units.
As an example, we can take that in order to find the exact surface area of a cuboid, we have to add the areas of all 6 faces.
In this figure, we can see that it can be stated as a cylinder.
So, as we know the formula of the surface area of a cylinder can be written as:
2[tex]\pi[/tex]rh + 2[tex]\pi r^2[/tex]
Here r = 8/2
=4 mi
h = 2 mi
Thus, putting the values, we have,
Surface area = [2 x 3.14 x 4 x 2] + [2 x 3.14 x 4 x 4]
= 50.24 + 100.48
= 150.72 [tex]mi^2[/tex]
