Answer:
212°
Step-by-step explanation:
We have the measure of CE and the measure of ED, so all we have to do is combine those two to get the measure of CED.
The arc CE measures 52 degrees.
The arc ED measures 160 degrees
The arc CED is the sum of arc CE and ED, so:
CED = 52° + 160° = 212°
We don't have any length measurement inside that circle to calculate the length of the arc CED in inches, centimeters or otherwise... so we can only measure it degrees.

Step-by-step explanation:
At an arcade there is a fee to purchase a game card. Any number of credits can then be added to the card at a constant cost per credit.Jude buys a card with 50 credits and it cost him 17. Audrey buys a card with 80 credits and it costs 26 how much would a card with 75 credits cost
Answer:
25 dollars
Step-by-step explanation:
To calculate the cost of a 75 credits card, we first find the cost per credit and the initial cost of the card, which are $0.18 and $8 respectively. The total cost is then $21.5.
Explanation:We know Jude bought a card with 50 credits for $17 and Audrey got one with 80 credits for $26. We can say that the cost per credit is constant. To find this cost per credit, we first need to calculate the difference between the costs and then divide the result by the difference in number of credits: So, cost per credit = (26-17) / (80-50) = 0.18. This implies for each credit the cost is 18 cents. For a 75 credit card, the price would be 75 * 0.18 = $13.5. However, this doesn't account for the initial cost to purchase the game card. If we say the initial cost is a flat fee included in the price Jude and Audrey paid, we need to subtract the total cost of the credits from their total spend to work this out: Jude’s initial cost = $17 - (50 * $0.18) = $8. Audrey’s initial cost = $26 - (80 * $0.18) = $8. As we supposed, initial cost is a constant of $8. Hence, the cost of a 75 credits card would include this initial cost: 75 credits would cost = $8 + 75 * $0.18 = $21.5.

The problem states that we need to assume that segments that appear tangent are actually tangent. From the figure, the tangent segment is the one that measures [tex]x[/tex] while the radius measures 24. The key in this problem is that if a radius of a circle and a tangent line to that circle touch intersect at the same point, then they form a right angle there.

Tell whether the lines for.the pair of equations are parallel, perpendicular, or neither y = - 4/5x + 3; 4x - 5y = -15
Answer:
The lines are neither parallel nor perpendicular
Step-by-step explanation:
The first step is to re-write the equations in slope-intercept form. The first equation is given as;
y = -4/5x + 3
This equation is already in slope-intercept form. Its slope is -4/5
The second equation is given as;
4x - 5y = -15
We solve for y;
-5y = -4x - 15
y = 4/5x + 3
The slope of the line is thus 4/5
Parallel lines have equal or identical slopes. The slopes of the two lines are not equal implying that the lines are not parallel. Two lines are said to be perpendicular if the product of their slopes is equal to -1.
The product of the slopes of the two lines is;
(-4/5) * (4/5) = -16/25 ≠ -1
The two lines are not perpendicular
By comparing the slopes of the given equations, y = -4/5x + 3 and 4x - 5y = -15, we find that they are negative reciprocals of each other, indicating that the lines are perpendicular.
To determine whether the given pair of equations represent lines that are parallel, perpendicular, or neither, we need to compare their slopes. The slope-intercept form of a line is y = mx + b, where m represents the slope and b represents the y-intercept.
The first equation is already in slope-intercept form: y = -4/5x + 3, so its slope is -4/5.
To put the second equation into slope-intercept form, we solve for y:
4x - 5y = -15
-5y = -4x - 15
y = (4/5)x + 3
The slope of the second line is 4/5.
Since the slopes of the two lines are negative reciprocals of each other, the lines are perpendicular.

The function f(x) = –12x + 144,000 is used to model the number of granola bars in stock depending on the number of boxes, x, one machine packages if the machine starts with 144,000 granola bars. The mathematical range for the function is the set of real numbers.
Which statement describes the limitation for the reasonable range compared to the mathematical range?
The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 12,000.
The reasonable range is limited to the rational numbers when 0 ≤ y ≤ 12,000.
The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.
The reasonable range is limited to the rational numbers when 0 ≤ y ≤ 144,000.
Answer:
The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.
Step-by-step explanation:
Notice that even though the range of the function is mathematically defined for all real numbers, in the real world you can't have more than 144,000 granola bars; that occurs when you have no boxes, or in other words, when x = 0
On the other hand, in the real word you can't have a negative quantity of a thing (you can't have minus 2 popsicles, for example). Given that granola bars are things, you must have at least 0 granola bars; in other words the quantity of granola bars must be greater or equal zero.
We know that in the real word you cant have more than 144,000 granola bars, and you must have at least 0 granola bars; therefore, the reasonable range of the function f(x) = –12x + 144,000 is 0 ≤ y ≤ 144,000.
Since we are talking of full granola bars here, the range is limited to whole numbers (whole granola bars).
We can conclude that the correct answer is: The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.
Final answer:
The accurate statement is: The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.
Explanation:
The question asks to identify the limitation of the reasonable range compared to the mathematical range for a function modelling the stock of granola bars, f(x) = – 12x + 144,000, based on the number of boxes, x, packaged by a machine.
The mathematical range could theoretically be any real number, but practically, since we are counting discrete items (granola bars), the reasonable range should be limited to whole numbers reflecting the actual possible quantities of granola bars in stock.
Additionally, since the stock cannot be negative and is started with 144,000 granola bars, the stock can range only down to 0 but not below, thus making the reasonable range from 0 to 144,000.
Therefore, the accurate statement is: The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.

At this point you need to check to make sure the angle at B is a right angle. Find the slope of the line segments AB and BC and check that the product of the slopes is -1.
From the diagram you can now see where the fourth point D has to be. If AB and CD are parallel then D must be 3 units to the left of C and 2 units above C. Find the coordinates of D and then check by finding the slopes of CD and DA and showing that the angle at D is a right angle.

Paul's car is 12 feet long. He is making a model of his car that is 1/7 the actual size. What is the length of the model?
Answer:
2 feet
Step-by-step explanation:
The model is the actual size. This means that for every 6 feet measured on the actual car, the model will span 1 foot.
Note that the model length is in the numerator and the actual length is in the denominator.
Thus, if the car is 12 feet long and L represents the length of the model, then write the ratio as .
Set the two ratios equal to each other to obtain the proportion below.
The length of the model is given below.
Therefore, the length of the model is feet.
The question is about scale conversion in mathematics. Given that Paul's full-sized car is 12 feet long and his model is 1/7th the size of the actual car, the length of the model car would be about 1.71 feet.
Explanation:The question involves a scale conversion in mathematics. If Paul's car is 12 feet long in real life, and his model is going to be 1/7th the size of the actual car, we need to determine the length of the model using this scaling factor.
To find out the length of the model, you multiply the actual length of the car by the scale factor, which in this case is 1/7. So, the calculation would be as follows:
12 feet (length of the car) * 1/7 (scale factor) = 1.71 feet (approx)
Therefore, the length of Paul's model car would be approximately 1.71 feet.

The area of a parallelogram is 216 cm². The height of the parallelogram is 2/3 of its base. Find the base and height.
Final answer:
The problem involves finding the base 'b' and height 'h' of a parallelogram with an area of 216 cm², where the height is 2/3 of the base. By substituting h = (2/3)b into the area formula, base x height, and solving, we find that the base is 18 cm and the height is 12 cm.
Explanation:
To find the base and height of the parallelogram given that the area is 216 cm² and the height is 2/3 of its base, we use the formula for the area of a parallelogram:
Base x Height = Area of parallelogram
Let the base be 'b' and the height be 'h'. According to the problem, h = (2/3)b, so we can substitute 'h' in the area
formula:
b x (2/3)b = 216 cm²
Which simplifies to:
(2/3)b² = 216 cm²
Now, solve for 'b' to find the base, and use that to find 'h' (the height):
b² = (216 cm²) x (3/2)
b² = 324 cm²
b = √(324 cm²)
b = 18 cm
Therefore, the base is 18 cm. Now we find the height:
h = (2/3) x 18 cm
h = 12 cm
The base of the parallelogram is 18 cm and the height is 12 cm.
