the radius of the circle is 3 yards, so the diameter would be 6 yards diameter = 2 x radius)
the diameter of the circle is also the base of the triangle.
the height f the triangle is 5 yards formula for area of a triangle is 1/2 x b x h
so you have 1/2 x 6 x 5 = 15 square yards
the area for a circle is PI x r^2
so you have 3.14 x 3^2 = 28.26 for the full circle so divide this by 2 for the half circle:
area of half circle = 28.26 / 2 = 14.13 square yards
now add the area of the triangle and half circle together:
14.13 + 15 = 29.13 square yards

the price for dinner in a resteraunt was $80. The customer paid an addition 7% meals tax and left a $15 tip. how much meals tax did the customer pay?
Answers
Final answer:
The customer paid a meal's tax of $5.60 on an $80 dinner, calculated by converting the 7% tax rate to a decimal (0.07) and multiplying it by the cost of the meal.
Explanation:
The question pertains to calculating the meal's tax that the customer paid when the price for dinner at a restaurant was $80 and the meal's tax rate was 7%. To calculate the meal's tax, we need to convert the percentage to a decimal and then multiply it by the total cost of the meal.
To do this:
Convert the percent to a decimal: 7% becomes 0.07.
Multiply this decimal by the cost of the meal: 0.07 × $80 = $5.60.
Therefore, the customer paid $5.60 in meal's tax.

• The z-score for 13.0 is -1.7
What is the standard deviation for this data set?
Answers
The formula for a z-score is
z = (X-μ)/σ
Using our information, we have
-1.7 = (13-18.1)/σ
Multiplying both sides by σ,
-1.7σ = 13-18.1
-1.7σ = -5.1
Divide both sides by -1.7:
-1.7σ/-1.7 = -5.1/-1.7
σ = 3

The measure of angle x in the isosceles triangle is 68 degrees.
The correct option is 68°.
What is the measure of angle x?The figure in the image is an isosceles triangle.
An isosceles triangle is simply a triangle that has any two sides equal in length and and also two angles equal in measure.
From the diagram;
Since the triangle is an isosceles triangle:
Angle 1 = 56 degrees
Angle 2 = 56 dgerees
Angle 3 = x
Note that the sum of the interior angle of a triangle adds up to 180 degree.
Hence;
Angle 1 + Angle 2 + Angle 3 = 180
56 + 56 + x = 180
Solve for x
112 + x = 180
x = 180 - 112
x = 68 degrees
Therefore, x has a value of 68 degree.

Tony collected data on years of employment and the annual salaries of the sales people at Company Z. He made a scatter plot and drew a trend line that approximated the line of best fit for the data, as shown on the right. Based on the trend line drawn for the data, what is the salary a salesperson with 3 years of employment at Company Z can expect to earn?
Answers
Answer:
The salary a salesperson expects to earn in 3 years, according to the graph is $40,000
Step-by-step explanation:
The estimated salary for a salesperson with 3 years of employment is $45,000.
How to write an equation of the line?Without the scatter plot, it's impossible to give an exact answer, but we can make an estimate based on the trend line. Assuming the trend line is a straight line, we can use the equation of the line to estimate the salary for a salesperson with 3 years of employment.
The equation of a straight line can be written in a slope-intercept form as y = mx + b, where y is the dependent variable (salary in this case), x is the independent variable (years of employment in this case), m is the slope of the line, and b is the y-intercept (the value of y when x = 0).
To find the equation of the trend line, Tony would have used statistical software or a calculator to calculate the slope and y-intercept of the line of best fit. He could also have done this by hand using the least squares regression method.
Once we have the equation of the trend line, we can substitute x = 3 to estimate the salary for a salesperson with 3 years of employment.
For example, if the equation of the trend line is y = 5000x + 30000 (where y is the salary in dollars and x is the years of employment), then we can estimate that a salesperson with 3 years of employment can expect to earn:
y = 5000(3) + 30000
y = 15000 + 30000
y = 45000
So the estimated salary for a salesperson with 3 years of employment is $45,000.

The question involves simplifying arithmetic expressions with square roots and division, emphasized on correctly applying order of operations and rules for dealing with exponents.
Explanation:The student's question involves simplifying expressions containing the square root and the division operation. To simplify expressions like 12 + √35 divided by 2 and 12 - 2√35 divided by 2, we need to perform operations step by step, applying the correct order of operations.
When parenthesis is used, it indicates that we should evaluate that part of the expression first, followed by multiplication or division, and finally addition or subtraction. It is important to pay careful attention to the operation signs and ensure that each step is followed correctly. Working with square roots and division can be tricky, but by breaking down the expression into smaller parts and solving them one by one, we can arrive at the correct answer.
For instance, to solve expressions like 3².35, we need to apply the exponential rules, such as xPx9 = x(p+q). This indicates that you should add the exponents when multiplying numbers with the same base. While this particular rule may not directly apply to the expression in question, knowing rules for operations with exponents can help simplify complex arithmetic expressions.

Write 9x+35=-5y in Slope-Intercept form
Answers
y = ax + c
So:
-5y = 9x + 35
We need to isolate y, so divide both sides by -5:
y = - [tex] \frac{9}{5} [/tex]x - 7
To solve this problem, we need to remember that slope-intercept form is y = mx +b, where the variable m represents the slope of the line and the variable b represents the y-intercept of the equation. To put the above equation into slope-intercept form, we need to get the variable y to the left side of the equation and the variable x and any constants to the right side of the equation.
9x + 35 = -5y
First, we will begin by adding 5y to both sides of the equation so that the y term is on the left side of the equation.
5y + 9x + 35 = 0
Next, we should subtract 9x from both sides so that the x term is on the left side of the equation.
5y + 35 = -9x
After that, we should subtract 35 from both sides of the equation so that this constant moves to the right side of the equation.
5y = -9x - 35
Now we must divide both sides of the equation by 5 so that the variable y is completely alone on the left side of the equation.
y = -9/5x - 7
Therefore, your answer y = -9/5x -7.
Hope this helps!

what is the triangle proportionality therom
Answers
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
The Triangle Proportionality Theorem asserts that a line drawn parallel to one side of a triangle divides the other two sides proportionally. This is related to the properties of similar triangles, where the corresponding sides of similar triangles are proportional due to the AAA similarity criterion.
The Triangle Proportionality Theorem states that if a line is drawn parallel to one side of a triangle, it divides the other two sides proportionally. This means that the segments created on one side of the triangle are in the same ratio as the corresponding segments on the other side of the triangle. For example, in [tex](\Delta ABC)[/tex] with a line parallel to [tex](\overline{BC})[/tex], the theorem asserts that [tex](\frac{AD}{DB} = \frac{AE}{EC})[/tex].
This concept is deeply rooted in the properties of similar triangles which are based on the Angle-Angle-Angle (AAA) similarity criterion. According to the AAA theorem, if two triangles have corresponding angles that are equal, then their corresponding sides are proportional. Thus, if two triangles are similar, the lengths of their corresponding sides form a proportion such as [tex](\frac{AB}{DE} = \frac{BC}{EF} = \frac{AC}{DF})[/tex], where each fraction is the ratio of a pair of corresponding sides.
The principles of the Triangle Proportionality Theorem can be applied in various geometric problems, often to compare the lengths of sides within the same triangle or in two similar triangles. It is also useful in determining distances or heights by applying the theorem to real-life scenarios, such as calculating the height of a wall using the shadow it casts, provided the sun's rays are considered parallel.
