Answer:
The measure of arc AC is [tex]136^o[/tex]
Step-by-step explanation:
Notice that angle BAC (whose measure is given as 34 degrees) is an inscribed angle, and according toe the inscribed angle theorem, the measure of an inscribed angle is half the measure of the central angle that subtends the same chord.
Then, the central angle that subtends the cord BC, is twice 34 degrees ([tex]2\,*\,34^o = 68^o[/tex])
Then, since they give us also the measure of the arc AB which is [tex]156^o[/tex], then the measure of arc AC can be estimated as the needed measure to complete [tex]360^o[/tex] as the sum of all three arcs. That is:
[tex]AC + AB+ BC = 360^o\\AC + 156^o+2\,*\,34^o = 360^o\\AC + 156^o+68^o = 360^o\\AC=360^o-156^o-68^o\\AC=136^o[/tex]
a salesperson at a car dealership earns a monthly salary of $2400 and $250 for each vehicle sold. a. how many vehicles does the salesperson need to sell in a month to earn $4400?
Answer:
8 vehicle.
Step-by-step explanation:
Given: Monthly salary of salesperson is $2400
Incentive of salesperson is $250 per vehicle sold.
First, lets compute income to earned apart from salary.
∴ Deduct salary from the target amount
[tex]\$ 4400-\$ 2400= \$ 2000[/tex]
∴ $2000 need to be earned only through incentive, which is $250 per vehicle sold.
Now, solving to get number vehicles to be sold to earn $2000 as incentive.
Number of vehicle= [tex]\frac{2000}{250}= 8\ vehicles[/tex]
∴ 8 vehicles need to be sold by salesperson to get total earning as $4400.
The salesperson needs to sell 8 vehicles to earn a total of $4400 in a month.
To determine the number of vehicles a salesperson needs to sell to earn a total of $4400, we can set up an equation based on the information provided.
The salesperson earns a fixed monthly salary of $2400 and an additional $250 for each vehicle sold. Let's denote the number of vehicles sold as x
We want the total earnings E to be $4400, so we set up the equation:
4400 = 2400 + 250x
Now, we solve for x
250x = 4400 - 2400
x= 8
Therefore, the salesperson needs to sell 8 vehicles to earn a total of $4400 in a month.

A custodian plans to repaint some classrooms. He has 5 = gallons of paint. All of
the bookcases are the same size and each requires 2 gallons of paint. How many
bookcases will he be able to repaint with that amount of paint? Show your work...
Answer: 2 bookcases.
Step-by-step explanation:
Let be "x" the number of bookcases that the custodian will be able to repaint completly with 5 gallons of paint.
According to the data given, the custodian needs 2 gallons of paint to repaint one bookcase. Since all the bookcases are equal, you can set up the following proportion:
[tex]\frac{2}{1}=\frac{5}{x}[/tex]
Now you must solve for "x" in order to find its value:
[tex](x)(\frac{2}{1})=5\\\\2x=5\\\\x=\frac{5}{2}\\\\x=2.5[/tex]
Notice that the custodian will be able to repaint 2 bookcases completely, then you can say that:
[tex]x\approx2[/tex]
The custodian will be able to repaint 2 bookcases with 5 gallons of paint.
Explanation:To determine the number of bookcases the custodian will be able to repaint with 5 gallons of paint, we need to divide the total amount of paint by the amount of paint required for each bookcase. Each bookcase requires 2 gallons of paint, so we divide 5 gallons by 2 gallons per bookcase:
5 gallons ÷ 2 gallons/bookcase = 2.5 bookcases
Since we cannot have 0.5 of a bookcase, the custodian will be able to repaint 2 bookcases with 5 gallons of paint.
A blueprint for a house states that a 6 inch line represents 11 feet on the actual home. If the house is to be a
total height of 20 feet, how many inches high would it be on the blueprint?
The house will be 10.9 inches high on the blueprint.
Step-by-step explanation:
Given,
Scale on blue print;
6 inch = 11 feet
We will find unit rate in terms of foot.
1 foot = [tex]\frac{6}{11}\ inches[/tex]
Therefore;
20 feet = [tex]\frac{6}{11}*20 = \frac{120}{11}[/tex]

The house would be approximately 10.91 inches tall on the blueprint to represent a 20-foot actual height.
The student asked how many inches high a house would be on a blueprint if the actual home is to be 20 feet tall, and a blueprint states that a 6-inch line represents 11 feet on the actual home. To solve this, we set up a proportion to determine the blueprint's height. The proportion is 6 inches/11 feet = x inches/20 feet, where x represents the height on the blueprint. First, write the proportion as 6 inches/11 feet = x inches/20 feet. Then, cross-multiply to get 11 feet * x inches = 6 inches * 20 feet. To find x, divide both sides of the equation by 11 feet, getting x = (6 inches * 20 feet) / 11 feet. After calculating, we find that x ≈ 10.91 inches. Therefore, on the blueprint, the house would be approximately 10.91 inches tall to represent an actual height of 20 feet.

4. Suppose the point B(2,8) is reflected across the x-axis and then translated according to the rule (x,y)→(y,x+4). What are the coordinates of B''? Show your work and explain.
Step-by-step explanation:
Point B(2, 8) reflect to x-axis
It means the x value won't change, the only thing that will change is the y value.
According to it, we can know that B' is (2, -8)
(2, -8) → (-8, 2+4) = (-8, 6) = B''
Final answer:
To obtain the coordinates of B'' after a reflection across the x-axis and a translation of (x,y)
ightarrow(y,x+4), point B(2,8) becomes B'(2,-8) after reflection and then B''(-8, 6) after translation.
Explanation:
The student is asking about the results of performing a geometric transformation on a point in the coordinate plane. Specifically, point B(2,8) is first reflected across the x-axis, and then is translated according to the rule (x,y)
ightarrow(y,x+4). To find the coordinates of B'', we follow these steps:
Reflect B across the x-axis: The x-coordinate remains the same, but the y-coordinate changes sign, resulting in B'(2,-8).
Apply the translation rule: We then take the coordinates of B' and apply the rule. The x-value of B' becomes the y-value of B'' and the y-value of B', decreased by 4, becomes the new x-value. Therefore, B'' = (-8, 2+4) = (-8, 6).
The final coordinates of B'' after the reflection and translation are (-8,6).

Jaquan bought 25 yards of cloth. He used 4.9 yards for a decoration and 10.6 yards to make costumes for the school play. Express the amount of cloth left over as a fraction in simplest form
Final answer:
To find the amount of cloth left over, subtract the amount used from the total amount. Jaquan had 9.5 yards of cloth left over, which can be expressed as the fraction 19/50.
Explanation:
To find the amount of cloth left over, we need to subtract the amount used from the total amount. Jaquan bought 25 yards of cloth, used 4.9 yards for a decoration, and used 10.6 yards to make costumes. To find the amount left over, we subtract the sum of 4.9 yards and 10.6 yards from 25 yards: 25 - 4.9 - 10.6 = 9.5 yards.
The amount of cloth left over can be expressed as a fraction by dividing the amount left over by the total amount. So, 9.5 yards can be written as the fraction 9.5/25, which can be simplified by dividing both the numerator and denominator by 0.5 to get 19/50. Therefore, the amount of cloth left over is 19/50.

A circle has a radius with endpoints at(2,5) and (-1,-4).Find the circumference and area of the circle.
Answer:
circumference is 59.6075
area is 282.743
Step-by-step explanation:
To find the circumference and area of the circle, we need to first find the radius. This can be achieved using the distance formula.
The distance formula goes as follows: for any two points on an coordinate plane, the distance can be calculated using a certain method. This method is the derived from the Pythagorean Theorem. Basically, you find the distance from right to left and square it, and then find the distance from up to down and square it. You add these two values together and then square root the whole thing. I know, its complicated.
To apply this to your problem, we do 2-(-1) to find the distance from right to left (x-distance) and then we do 5-(-4) to find the distance from up to down (y-distance). 2-(-1)=3 and squaring that we get 9. 5-(-4)=9 and squaring that we get 81. Adding these two values together, we get 90 and square rooting it we get [tex]\sqrt{90}[/tex].
The formula for circumference of a circle is 2Pi * radius and plugging in our values we get 2Pi * [tex]\sqrt{90}[/tex] which gives us approximately 59.6075.
The formula for area of a circle is Pi * radius^2 and plugging in our values we get Pi * [tex]\sqrt{90}[/tex] ^2 which gives us approximately 282.743.
