Answer:
B
Step-by-step explanation:
∠ BEF and ∠ CFE are alternate angles and congruent, thus
3x + 20 = 2x + 50 ( subtract 2x from both sides )
x + 20 = 50 ( subtract 20 from both sides )
x = 30
Thus
∠ CFE = 3x + 20 = 3(30) + 20 = 90 + 20 = 110°
∠ CFE and ∠ AEF are same- side interior angles and are supplementary, thus
∠ AEF = 180° - 110° = 70° → B

The temperature outside dropped 13°F in 7 hours. The final

Answers
Answer:
11
Step-by-step explanation: Since the question does not specify wether the temperature dropped every hour or if it was the total, in this case we can assume this was in total. If you ended up with -2 after subtracting 13, to get the starting temperature you can add -2 to 13.
-2 + 13 = 11

An airline company has a 60% markup rate on its tickets. If the original cost of a ticket is $229, what is the amount of markup?
Answers
To find the amount of markup on an airline ticket costing $229 with a 60% markup rate, multiply the original cost by the markup rate (0.60), resulting in a markup amount of $137.40.
Explanation:The question asks to find the amount of markup on an airline ticket that has an original cost of $229 and a markup rate of 60%. To calculate the markup amount, we need to apply the markup rate to the original cost. The formula to find the markup amount is: Markup Amount = Original Cost × Markup Rate.
Given that the original cost is $229 and the markup rate is 60% (or 0.60 when expressed as a decimal), the calculation would be:
• Markup Amount = $229 × 0.60 = $137.40
Therefore, the amount of markup on the airline ticket is $137.40.

1,436 with a remainder of 4
Step-by-step explanation:
The first step is to see how many times 6 goes into 8
It goes in 1 time so you write 1 at the top and subtract 6 from 8
This gives you 2, and then you bring down the 6 from the 8,620
Now you have 26, and you see how many times 6 goes into 26
It goes in 4 times giving you 24 so you write 4 at the top
Then you subtract 24 from 26 giving you 2 and you drop down the 2
This gives you 22 and 6 goes into 22 3 times giving you 18
So you write 3 at the top and subtract 18 from 22 giving you 4
then you drop down the 0 from the 8,620 giving you 40
Then you evaluate how many times 6 goes into 40, it goes in 6 times
this gives you 36 and then you writes a 6 at the top and subtract 40 and 36
this gives you a remainder of 4

Stay Safe! Stay at Home!! =)
The slope between the points (8,-4) and (2,-4) is 0, indicating a horizontal line.
Explanation:To find the slope between two points, you use the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
Let's apply this formula to the points given: (8, -4) and (2, -4).
Slope (m) = (-4 - (-4)) / (2 - 8) = (0) / (-6) = 0
Since the numerator of the slope formula is zero, the slope of the line passing through these two points is 0, which indicates a horizontal line.

X and y vary inversely. If x is 3 when y is 12, find the equation to model this situation
Answers
Answer:
[tex]x = \dfrac{36}{y}[/tex]
Step-by-step explanation:
We are given the following in the question:
x and y vary inversely.
[tex]x\propto \dfrac{1}{y}[/tex]
Removing the sign of proportionality and adding the constant of proportionality, we get,
[tex]x = k\times \dfrac{1}{y} = \dfrac{k}{y}[/tex]
where k is the constant of proportionality.
When x = 3, y = 12
Putting these value in the equation, we get,
[tex]3 = \dfrac{k}{12}\\\\\Rightarrow k = 12\times 3 = 36[/tex]
Putting value of k, we get,
[tex]x = \dfrac{36}{y}[/tex]
which is the required equation to model the given situation.

At first, Brianna earned a score of 90 on the quiz. She discovered that 4 had been taken off by mistake. Brianna showed the teacher, removed the 4-points deduction. Which two quiz scores could be used to find Briannas new quiz score
1.90+ (-4)
2.90+4
3.90-4
4.90-(-4)
Answers
To find Brianna's new quiz score after correcting a mistake, we can use two mathematical operations: 90 + 4, which adds the points back directly, or 90 - (-4), which mathematically corrects the wrongful deduction by subtracting a negative.
Explanation:The question involves finding Brianna's new quiz score after correcting a mistake. At first, she earned a score of 90 on the quiz, but then discovered that 4 points had been taken off by mistake. To correct this, we should add the 4 points back to her original score of 90.
The correct mathematical operation to use would be 90 + 4, because we are adding back the points that were mistakenly deducted. Another way to express this correction is by removing the negative effect of the 4-point deduction, which mathematically would look like 90 - (-4). When we subtract a negative, it is equivalent to adding the positive value of that number.
Therefore, the two quiz scores that could be used to find Brianna's new quiz score are:
90 + 4: This represents simply adding the 4 points back to the original score.90 - (-4): This represents the same thing but highlights the corrective action of subtracting a mistakenly applied negative value.Final answer:
The correct options for calculating Brianna's new quiz score after the mistake is corrected are (2) 90 + 4 and (4) 90 - (-4), both of which correctly add 4 points to the original score of 90.
Explanation:
The correct way to calculate Brianna's new quiz score after the mistaken 4-point deduction is revoked would be by taking the original score of 90 and adding the 4 points back. Therefore, the two quiz scores we could use to find Brianna's new quiz score are:
90 + (-4), which is subtracting the 4 points that were mistakenly deducted, but since we want to reverse that deduction, this would not be used.
90 + 4, which correctly adds the 4 points back to the original score.
90 - 4, which would mistakenly subtract 4 more points instead of adding them back.
90 - (-4), which is essentially the same as adding 4 to 90, and it also gives the correct new score.
We disregard the options that subtract 4 points. Therefore, the correct options to use for finding Brianna's new quiz score are (2) 90 + 4 and (4) 90 - (-4).

D. 2.6 X 10 ^-4 pound
Answers
Answer:
A. 6.2 X 10 ^-3
Step-by-step explanation:
First, you have to find the total weight by adding 0.0002 and 0.006 together, which gives you 0.0062. Then, follow basic setup of scientific notation by moving the decimal until one non-zero digit is to the left of the decimal, which brings the decimal to 6.2. Since you are moving the decimal right three places, the exponent is negative 3, making the notation 6.2 X 10 ^-3

A target with a diameter of 42 cm has 4 scoring zones formed by concentric circles. The diameter of the center circle is 6 cm. The width of each ring is 6 cm. A dart hits the target at a
random point. Find the probability that it will hit a point in the yellow region
Answers
The probability of a dart hitting the yellow region of the target can be calculated by determining the area of the yellow region, in this case about 1130.97 cm^2, and dividing it by the total area of the target, which is about 1385.44 cm^2. The resulting probability is approximately 0.82, or 82%.
Explanation:To solve this, we must first understand that the probability of the dart hitting a certain zone on the target will be proportional to the area of that zone. In this case, the entire area of the target is the area of the circle with a diameter of 42 cm. The radius of the target, therefore, is 21 cm.
The formula for the area of a circle is πr^2, so the area of the target is π * (21)^2, or about 1385.44 cm^2.
While the yellow zone is the ring with 18 cm diameter. Using the formula for the area of a circle again, the inner boundary of the yellow zone will have an area of π * (9)^2, or about 254.47 cm^2. The area of the yellow zone is the difference between these two values, which is around 1130.97 cm^2.
To find the probability of a dart hitting the yellow zone, we divide the area of the yellow zone by the total area of the target. This gives us a probability of around 0.82, or 82%.

find the radius of the sphere with a volume of 32/81 π cubic yards. Write your answer as a fraction in simplest form.
Answers
Answer:
Step-by-step explanation:
The radius of the sphere with a volume of 32/81 π cubic yards is 2/3 yards. This is found by equating the given volume to the volume of a sphere formula and solving for the radius step-by-step.
To find the radius of a sphere given its volume, we can use the formula for the volume of a sphere, which is V = (4/3)πr³. In this case, we have the volume V= 32/81 π cubic yards. We need to solve for r (the radius).
First, we set the given volume equal to the volume formula:
32/81 π = (4/3)πr³
To solve for r³, we divide both sides by (4/3)π:
r³ = (32/81 π) / ((4/3)π) = (32/81) / (4/3) = 32/81 * 3/4 = 32/108 = 8/27
Now, to find r, we take the cube root of both sides:
r = ³√(8/27)
Since ³√8 = 2 and ³√27 = 3, the radius r is 2/3 yards.
