RATE is a quadrilateral inscribed in the above circle with arc measures shown above. What is the measure of the smallest angle in RATE?
Answer:
The measure of the smallest angle is 77°
Step-by-step explanation:
* Lats study some facts about the circle
* In any circle; If the vertices of a quadrilateral lie on its
circumference then the quadrilateral is called a cyclic quadrilateral
- In any cyclic quadrilateral each two opposite angles are supplementary
that means their sum = 180°
* In any circle; if the vertex of an angle lies on the circumference
is called an inscribed angle
- The inscribed angle subtended by the opposite arc
- The measure of the inscribed angle = 1/2 the measure of
the subtended arc
* Now we can solve our question
∵ R , A , T , E all on the the circumference of the circle
∴ RATE is a cyclic quadrilateral
∵ Angle RAT is an inscribed angle subtended by arc RET
∵ The measure of arc RE = 121°
∵ The measure of arc ET = 51°
∴ The measure of arc RET = 121 + 51 = 172°
∵ m∠RAT = (1/2) measure of arc RET
∴ m∠RAT = (1/2) × 172 = 86°
∵ Angle ATE is an inscribed angle subtended by arc ARE
∵ The measure of arc AR = 85°
∵ The measure of arc RE = 121°
∴ The measure of arc ARE = 85 + 121 = 206°
∵ m∠ATE = (1/2) measure of arc ARE
∴ m∠ATE = (1/2) × 206 = 103°
* Now lets find the remainder angles by using cyclic quadrilateral
∵ RATE is a cyclic quadrilateral
∴ m∠RAT + m∠RET = 180°
∵ m∠RAT = 86°
∴ m∠RET = 180 - 86 = 94°
* Similar;
∵ RATE is a cyclic quadrilateral
∴ m∠ATE + m∠ARE = 180°
∵ m∠ATE = 103°
∴ m∠ARE = 180 - 103 = 77°
* The measure of the smallest angle is 77°

Find the value of y.
Answer options: 62, 66, 70, 74
Answer:
The value of y = 70°
Step-by-step explanation:
∵ The measure of the major arc = 160 + 60 = 220°
∵ The measure of the circle is 360°
∴ The measure of the minor arc = 360 - 220 = 140°
∵ y is the angle between a chord and a tangent
∵ The chord subtended by the arc of measure 140°
∵ y is subtended by the arc of measure 140°
∵ Angle of tangent subtended by an arc,
its measure = half the measure of the subtended arc
∴ The measure of y = 1/2 the measure of the subtended arc
∴ y = 1/2 × 140 = 70°
Answer:
70

What point is on the graph of f(x)=4x
The point (1, 4) is on the graph of the function f(x)=4x.
To find a point on the graph, we can choose any value for x and compute the corresponding y-value using the function's formula.
For example, if x = 1, then f(1) = 4(1) = 4, so one point on the graph is (1, 4).
The point (1, 4) fulfills the dependence of y on x represented by the function f(x).

The original cost of a lamp is $18.95. The lamp is on sale for 25% off. How much will you pay
Answer:
$14.21
Step-by-step explanation:
To find 25% of 18.95, you can multiply 18.95×0.25, which approximately equals $4.74. Then subtract $4.74 from $18.95 to get $14.21
Answer:
$14.2125
Step-by-step explanation:
We have been given that the original cost of a lamp is $18.95. The lamp is on sale for 25% off.
Since the lamp is on a 25% sale, then the cost of the lamp would be 75% (100%-25%) of the original price.
[tex]\text{Cost of lamp after sale}=\$18.95\times \frac{75}{100}[/tex]
[tex]\text{Cost of lamp after sale}=\$18.95\times 0.75[/tex]
[tex]\text{Cost of lamp after sale}=\$14.2125[/tex]
Therefore, you will have to pay $14.2125 for the lamp.

What is the value of x?
Answer options: 225, 135, 90, 180
Answer:
180
Step-by-step explanation:
We can use the central angle theorem to understand this problem.
The Central Angle Theorem states that the inscribed angle that fall on the opposite side of the circumference is half of the arc subtended by it.
The angle that is on the opposite side of the circumference is a right angle and thus it measures 90°. This is half of the arc labeled x. So x is twice that of 90.
So, x = 180 degrees
Answer:
180°
Step-by-step explanation:
The angle subtended by the arc is calculated as follows. The angle made at the center by an arc is twice the angle subtended at the circumference.
In the figure the angle subtended at the circumference by the arc is a right angle, that is, 90° thus the angle that subtends the arc is 2×90=180°
△ABC is inscribed in a circle. Find the angle between the tangents to the circle at points B and C, if m∠CAB=50°.
Answer:
80°
Step-by-step explanation:
We know the measure of ∠CAB. This is an inscribed angle; this means its measure is 1/2 that of the intercepted arc, BC. This means the measure of BC is 100°.
This makes the measure of arc BAC is 360-100 = 260°.
The measure of the angle formed by the tangents, since it is outside the circle, will be 1/2 of the difference of the intercepted arcs. This means the measure of this angle will be
1/2(260-100) = 1/2(160) = 80°
Based on the information given, it should be noted that the angle between the tangents to the circle at points B and C will be 80°.
From the given information, we've been given the measure of ∠CAB which is 50°.Since this is an inscribed angle, it implies that the measure is 1/2 that of the intercepted arc, BC. Therefore, the measure of BC will be: = 50/0.5 = 100°.Therefore, the measure of arc BAC will be: = 360° - 100° = 260°.It should be noted that the angle between the tangents to the circle at points B and C will therefore be calculated thus:
= 1/2(260-100)
= 1/2(160)
= 80°
In conclusion, the correct option is 80°.

Can you conclude that this parallelogram is a rectangle? Explain.
the parallelogram in the image is a rectangle. There are two ways to tell this from the information given: The diagonals of a rectangle bisect each other, but the diagonals in the image do not bisect each other. The opposite sides of a rectangle are congruent, and the sides of the parallelogram in the image appear to be congruent.
The diagonals are perpendicular. In the image, one of the answer choices states that the diagonals are perpendicular, and this is the key giveaway. Diagonals of a rectangle are always perpendicular, so if a parallelogram has perpendicular diagonals, it must be a rectangle.
The diagonals are congruent. Another answer choice states that the diagonals are congruent. While this is also true for rectangles, it is not true for all parallelograms. So, while not all parallelograms with congruent diagonals are rectangles, all rectangles do have congruent diagonals.
Therefore, based on the information given in the image, we can conclude that the parallelogram is a rectangle.
Here are some additional properties of rectangles that you may find helpful:
Opposite sides of a rectangle are equal and parallel.
Opposite angles of a rectangle are equal.
All angles of a rectangle are right angles.

Which phrase could the expression x-4 represent? a number less than 4 the difference of a number and 4 the sum of a number and 4 four less a number
Answer:
Four less a number
Step-by-step explanation:
x-4 is literally subtracting 4 and 4 less a number is basically also subtracting 4 from an equation.
Answer:
The difference of a number and 4.Step-by-step explanation:
The sentence that represents better the given expression is "The difference of a number and 4".
Mainly because states the difference in the right order, first the unknown number, which is called "a number", and in second place the number 4, referring to the difference is the subtract of 4 units from the number, not in the opposite way.
On the other hand, "a number less than 4" specifies that the unknown number is minor than 4, which is not true. "the sum of a number and 4" is completely wrong, because there's no sum at all. "Four less a number" refers to a difference but in the opposite way 4-x.
Therefore, the right answer is
The difference of a number and 4.The second angle of a triangle is 3 times as large as the first. The third angle is 50° more than the first. Find the measure of the smallest angle
Your smallest angle is 26°
Angles in a triangle add up to 180°. This means:
Angle1 + Angle2 + Angle3 = 180°
The second angle of a triangle is 3 times as large as the first.
Angle2 = 3 * Angle1
The third angle is 50° more than the first.
Angle3 = Angle1 + 50°
Substitute these into the first formula, in terms of Angle1.
Angle1 + (3 * Angle1) + (Angle1 + 50°) = 180°
Expand and simplify.
5 * Angle1 + 50° = 180°
Put it into the formula Ax = B. You will have all the variables on one side and the integers on the other.
5 * Angle1 + 50° = 180°
5 * Angle1 + 50° - 50° = 180° - 50°
5 * Angle1 = 130°
Put it into the formula x = b. Solve to find 1 of the variable.
5 * Angle1 = 130°
5 * Angle1 / 5 = 130° / 5
Angle1 = 26°
Check this is right by substituting into the given formulas.
Angle2 = 3 * Angle1
Angle2 = 3 * 26
78 = 3 * 26
Angle3 = Angle1 + 50°
Angle3 = 26 + 50°
76 = 26 + 50°
Angle1 + Angle2 + Angle3 = 180°
26 + 78 + 76 = 180°
The smallest angle of the triangle is 26 degrees.
Explanation:The question is referring to a triangle, and the sum of the angles in a triangle is always 180°. Let's denote the first angle as 'x'. According to the question, the second angle is 3x and the third angle is x + 50°. Therefore, we set up the equation x + 3x + x + 50 = 180. This simplifies to 5x + 50 = 180. After subtracting 50 on both sides of the equation, we get 5x = 130, and hence, x = 130 / 5 = 26. Therefore, the smallest angle is 26°.

what are the mean, median, mode, and range for this set 5.1, 3.7, 3.1, 4.3, 7, 2, 4.3, 2.5
Answer:
Mean: 4, Median: 4, Mode: 4, Range: 5
Step-by-step explanation:
First Put the numbers in order from least to greatest:
2, 2.5, 3.1, 3.7, 4.3, 4.3, 5.1, 7
MEAN: The mean of a group of numbers is the the average so we'll add up all the numbers then divide them by the amount of numbers total. In this case: the um of all the numbers is 32. We are going to now dived 32 by 8, because there are 8 numbers. Using my multiplication facts, I know that 8*4 equals 32, therefore, 32/8 equals 4. So your mean is 4
MEDIAN: Your median is the middle number. This is why it was helpful to put the numbers in alphabetical order. In this one, you will cross off numbers from each end to find the one in the middle. Here is where it would be good to have a piece of paper and a pencil to cross out the numbers as you go. If you don't have paper, you can use your fingers, which is what I did. Take your finger and put it in front of the end numbers and from there keep going until you have a final middle number. In this case, there are 2 numbers in the middle, so you take the average of those 2 numbers. The two numbers in this problem are 3.7 and 4.3. You ad those together, and you get 8, now you divide 8 by 2 because you have 2 numbers. 8/2 is 4. So your median is 4.
MODE: is the easiest. It's simply the number that appears the most times in the sequence of numbers. so the mode here is 4.3.
RANGE: Range is the difference between the number with the highest value and the number with the lowest value. The highest value is 7 and the lowest is 2. 7-2 equals 5. So your range is 5
I hope this was helpful!
To calculate the mean, add all numbers together and divide by the count: the mean is 4. Order the numbers to find the median, which is the average of the two middle numbers: the median is also 4. The mode is the most frequent number: in this case, 4.3. Lastly, the range is the difference between the largest and smallest numbers: the range is 5.
To find the mean, median, mode, and range of the given set of numbers (5.1, 3.7, 3.1, 4.3, 7, 2, 4.3, 2.5), let's calculate each one step-by-step.
Mean: Add up all the numbers and divide by the total count:
Mean = (5.1 + 3.7 + 3.1 + 4.3 + 7 + 2 + 4.3 + 2.5) / 8
Mean = 32 / 8 = 4. The mean is 4.
Median: Order the numbers from least to greatest and find the middle number. If there is an even number of data points, take the average of the two middle numbers: 2, 2.5, 3.1, 3.7, 4.3, 4.3, 5.1, 7.
Median is (3.7 + 4.3) / 2 = 4.
Mode: The number that appears most often. In this set, 4.3 appears twice, so the mode is 4.3.
Range: Subtract the smallest number from the largest number in the set: 7 - 2 = 5. The range is 5.
Therefore, the mean is 4, the median is 4, the mode is 4.3, and the range is 5.
