What do you do about the arc? It is 211o - 1? That value = the central angle. A central angle is the angle going from K to the center of the circle to M. 1/2 that amount is the angle going to anywhere on the arc of the circle. So that is 1/2 of 211 - 1 = 105.5x - 1/2
These two angles when added together = 180o
105.5x - 1/2 + 104x + 1 = 180o Collect like terms on the left
209.5x + 1/2 = 180 Subtract 1/2 from both sides
209.5x = 180 - 1/2
209.5x = 179.5 Divide by 209.5
x = 179.5 / 209.5
x = 0.8568

Charlene is looking at a pair of earrings that costs 10$. Find the totlat cost of the earrings if there is a 15% discount and the sales tax is 8%.Does it matter if the discount is taken before if after the sales tax is added?
Answers
Remark
The correct method is to take the reduction and then add the sales tax. It turns out you get the same answer no matter which way you do it. But the IRS is only interested in the tax put on the eventual selling price and not on any theoretical price you may have gotten before the reduction
Obviously the government would prefer the second method (they get more taxation income) but so far they have not closed that loophole.
Correct Method
Cost of earrings = $10
Find 15% reduction 10*15% = 10*15/100 = 1.5 dollars.
Find the reduced price
10 - 1.5 dollars = 8.5 dollars.
Find the tax on 8.5 dollars.
Amount Tax = 8.5 * 8/100 =0.68 dollars
Add this onto 8.50
Total Cost = 8.50 + 0.68 = $9.18
Answer to Question about order
Now suppose you take the tax first and add it on.
10 * 8/100 = 0.80
Add this onto the selling price 10 + 0.80 = 10.80
Now take the 15% reduction
10.80 * 15/100 = 1.62
Subtract this from the taxed amount
10.80 - 1.62 = 9.18 which doesn't seem to matter.

In Samantha's English class, her current grade is calculated by finding the average of the scores she received on her terms papers. Samantha's last term paper brought her average up to a 91 from an 89, which was her average from the first three. Samantha claims that she scored a 97 on her fourth term paper. Is Samantha's claim true?
Answers
This means, her total scores in first three test were = 3 x 89 = 267
Her average in four tests = 91
This means, her total scores in four tests are = 364
267 give the sum of first three test scores. and 364 give the sum of scores with fourth test adding in three tests.
So, subtracting 267 from 364 will give us the scores of Fourth test.
Scores of Fourth test = 364 - 267 = 97
Thus, Samantha's Claim is correct

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.

l= 5500(.115)(5 )= $3162.5 is the total amount of interest to pay.
Answer:
The amount of Mark's Total payment is $9478.15.
Step-by-step explanation:
Given : Mark borrowed $5,500 at 11.5 percent for five years.
To find : What is the amount of Mark's total payment?
Solution :
Using compound interest formula,
[tex]A=P(1+r)^t[/tex]
Where A is the amount,
P is the principle P=5,500
r is the rate r=11.5%=0.115
t is the time t= 5 years
Substitute the value,
[tex]A=P(1+r)^t[/tex]
[tex]A=5500(1+0.115)^5[/tex]
[tex]A=5500(1.115)^5[/tex]
[tex]A=5500(1.7233)[/tex]
[tex]A=9478.15[/tex]
Therefore, The amount of Mark's Total payment is $9478.15.

A=12h(b1+b2) solve for b1 please.
Answers
Plus, if you are finding the area
the equation would be like this
A: 1/2 (b1+b2) x 12h
Isolate b1 in the equation A=12h(b1+b2) by first subtracting 12h*b2 from both sides and then divide both sides by 12h. The result is b1 = (A - 12h*b2) / 12h.
Explanation:In order to solve the equation A=12h(b1+b2) for b1, we need to isolate b1. We begin by subtracting the product of 12h times b2 from both sides of the equation. This gives us A-12h(b2) = 12h(b1).
Next, we divide both sides of the equation by 12h to solve for b1, resulting: b1 = (A - 12h*b2) / 12h.
So, if you can determine the values of A, b2, and h from your problem, you can substitute those in to get your solution for b1.

When designing a building, you must be sure that the building can withstand hurricane force winds, which have a velocity of 73mi/h or more. The formula f = 0.004av2 gives the force f in pounds exerted by a wind blowing against a flat surface. A is the area of the surface in square feet and v is the wind velocity in miles per hour. How much force is exerted by a wind blowing at 81 mi/h against the side of the building shown?
Answers
To calculate the force exerted by the wind blowing against the side of the building, you can use the formula f = 0.004av², where f is the force, a is the area of the surface, and v is the wind velocity. Given the wind velocity of 81 mi/h, you need to determine the area of the surface to calculate the force.
Explanation:The formula to calculate the force exerted by a wind blowing against a flat surface is given as f = 0.004av², where f is the force in pounds, a is the area of the surface in square feet, and v is the wind velocity in miles per hour.
In this case, we are given that the wind velocity is 81 mi/h. To calculate the force exerted by the wind, we need to know the area of the surface.
Once we have the area, we can substitute the values into the formula and calculate the force.

6 clients are throwing a party. Each cake serves 24 servings and has a party of 70 +3staff how many cakes are needed?
Answers
To serve 73 people at a party, 4 cakes are needed since each cake serves 24 people and it is not possible to have a fraction of a cake.
Explanation:To determine how many cakes are needed for a party with 70 guests and 3 staff members, we need to calculate the total number of servings required and then divide this by the number of servings each cake provides.
First, we add the number of guests and staff to find the total number of people at the party:
Number of guests: 70Number of staff: 3Total number of people: 70 + 3 = 73Each cake serving is designed to serve 24 people. We divide the total number of people by the number of servings per cake to find out how many cakes are needed:
(Total number of people) ÷ (Servings per cake) = Number of cakes
73 ÷ 24 = 3.04166667
Since you cannot have a fraction of a cake, you need to round up to the next whole number. Therefore, you need 4 cakes to have enough servings for everyone at the party.

4 cakes are needed for the party to ensure that each of the 70 guests and 3 staff members receives a serving of cake.
To determine the number of cakes needed, we must first calculate the divide that number by the number of servings each cake provides.
First, we add the number of guests to the number of staff:
70 guests + 3 staff = 73 people in total.
Next, we need to ensure that each person gets one serving of cake. Since each cake serves 24 servings, we divide the total number of people by the number of servings per cake:
73 people · 24 servings per cake = 3 cakes with some servings left over.
Since we cannot serve a fraction of a cake, we must round up to the nearest whole number to ensure that there are enough servings for everyone. Therefore, we need 4 cakes in total to serve all 73 people at the party.
In conclusion, 4 cakes are needed for the party to ensure that each of the 70 guests and 3 staff members receives a serving of cake.
