Quadrilateral ABCD is a rhombus. Given that m<EDA = 37º, what are the measures of m <AED |
m<DAE, and m<BCE ? Show all calculations and work
In the given rhombus ABCD, where angle EDA is 37º, we can determine the measures of angle AED, angle DAE, and angle BCE. Angle AED is equal to 180º minus twice angle EDA, which gives us 106º. Angle DAE is equal to angle EDA, so it is 37º. Angle BCE is equal to angle AED divided by 2, resulting in 53º.
A rhombus is a parallelogram with all four sides equal in length. Since ABCD is a rhombus, all four angles are equal, denoted by m<ABC = m<BCD = m<CDA = m<DAB.
We are given that angle EDA is 37º. In a rhombus, opposite angles are congruent, so we have m<CDA = 37º.
To find the measure of angle AED, we use the fact that the sum of angles around a point is 360º. Since angle AED is an exterior angle to triangle CDA, we can write: m<AED + m<CDA + m<DAE = 360º. Substituting the given values, we have: m<AED + 37º + m<DAE = 360º. Rearranging the equation, we find: m<AED + m<DAE = 360º - 37º = 323º.
Since ABCD is a rhombus, opposite angles are congruent, so we have m<DAB = m<CDA = 37º. Therefore, m<DAE = m<DAB = 37º.
Substituting the value of m<DAE in the equation m<AED + m<DAE = 323º, we find: m<AED + 37º = 323º. Solving for m<AED, we get: m<AED = 323º - 37º = 286º.
Finally, to find the measure of angle BCE, we know that opposite angles in a rhombus are congruent, so m<BCD = m<DAB = 37º. Since BCE is an exterior angle to triangle BCD, we can write: m<BCE + m<BCD + m<CBE = 360º. Substituting the given values, we have: m<BCE + 37º + m<CBE = 360º. Rearranging the equation, we find: m<BCE + m<CBE = 360º - 37º = 323º.
Since opposite angles in a rhombus are congruent, m<BCE = m<DAB = 37º. Substituting this value in the equation m<BCE + m<CBE = 323º, we get: 37º + m<CBE = 323º. Solving for m<CBE, we find: m<CBE = 323º - 37º = 286º.
Therefore, the measures of the angles in the given rhombus ABCD are: m<AED = 286º, m<DAE = 37º, and m<BCE = 53º.

Mr. Whittaker’s science class uses tide gauges to measure annual variations in water levels at different parts of a river, and then compares those variations to the average annual trend. Matea recorded that the water level in one part of the river fell 1. 05 millimeters per year for 2. 48 years. This data will be compared to the average annual trend, which shows the water level rising 1. 8 mm/year. Which number represents the rate at which the water level fell? Which number should the rate be multiplied by to find the total variation in water level?.
The water level in one part of the river fell at a rate of 1.05 millimeters per year for a duration of 2.48 years. The average annual trend, however, indicates that the water level rises at a rate of 1.8 mm/year.
In Matea's recorded data, the rate at which the water level fell is given as 1.05 millimeters per year. This represents the change in water level over a period of one year. To calculate the total variation in water level, we need to multiply the rate of change by the duration of the observation. In this case, the observation lasted for 2.48 years.
To find the total variation, we multiply the rate of change (1.05 mm/year) by the duration (2.48 years):
Total variation = Rate of change * Duration
= 1.05 mm/year * 2.48 years
= 2.604 mm
Therefore, the water level in that particular part of the river fell by 2.604 millimeters over the course of 2.48 years.
It is important to note that the average annual trend, which indicates the water level rising at a rate of 1.8 mm/year, is not relevant to determining the rate at which the water level fell or calculating the total variation. The average annual trend is simply a reference point for comparison to assess whether the observed variation is consistent with the overall trend.

The measure of angle Y is approximately equal to 117.11 degrees. Therefore, m∠Y = 117.11°.
Given that a triangle ΔXYZ has the sides XY = 6.32, YZ = 5.83, and XZ = 11.05, we need to find the measure of angle Y.
Let's use the cosine law which states that c² = a² + b² - 2abcosC
where a, b, and c are the sides and C is the angle between the sides a and b.
Applying the cosine law to triangle ΔXYZ and substituting the given values, we have:
11.05² = 6.32² + 5.83² - 2(6.32)(5.83)cos Y
cos Y = (6.32² + 5.83² - 11.05²) / (2(6.32)(5.83))
cos Y ≈ -0.4151
Taking the inverse cosine on both sides, we get:
m∠Y = cos⁻¹(-0.4151)

What property allows one to set aside the order of operations how
The property that allows one to set aside the order of operations is called the Commutative Property. The order of operations is also known as the PEMDAS rule.
The order of operations, also known as the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), is a fundamental principle in mathematics that dictates the sequence in which operations should be performed in an arithmetic expression. However, there are instances where the order of operations can be set aside or rearranged without affecting the final result. This is possible due to the Commutative Property, which applies to addition and multiplication.
The Commutative Property states that the order in which numbers are added or multiplied does not change the result. For addition, it means that the sum of two numbers remains the same regardless of the order in which they are added.
By applying the Commutative Property, one can rearrange the order of addition or multiplication operations, allowing for more flexibility in evaluating expressions. This property is particularly useful when simplifying or solving mathematical equations, as it enables us to change the order of terms without altering the final outcome. However, it's important to note that the Commutative Property does not apply to subtraction or division operations, and the order of operations should be followed strictly in such cases.

In order to determine the predetermined overhead rate and allocate manufacturing overhead costs, it is necessary to estimate the allocation base and the total manufacturing overhead costs in advance.
These estimates help in establishing a systematic method for assigning overhead costs to products or services based on a relevant allocation base.
Manufacturing overhead costs include various indirect expenses such as factory rent, utilities, equipment maintenance, and supervision. These costs cannot be easily traced directly to specific products or services. Instead, they are allocated based on a predetermined overhead rate.
The allocation base is a measure or activity that serves as a common denominator for distributing overhead costs. Common allocation bases include direct labor hours, machine hours, or material costs. The choice of allocation base depends on the nature of the business and the activities that drive overhead costs.
To determine the predetermined overhead rate, the total estimated manufacturing overhead costs for a specific period are divided by the estimated allocation base. This rate is then applied to the actual allocation base incurred during production to allocate the overhead costs to individual products or services.
Estimating the allocation base and the total manufacturing overhead costs in advance allows for a more accurate and consistent allocation of overhead expenses. It helps businesses establish a systematic approach to assign costs, aiding in decision-making, cost analysis, and determining product or service pricing.

The sum of the interior angles of the polygon is 540 degrees. Create an equation to solve for x:
Part 2: Find the measure of x, then find the measures of each unknown angles
To find the measure of x and the unknown angles in a polygon, we can create an equation based on the sum of the interior angles, which is 540 degrees.final answer is 108°.
Let's assume the polygon has n sides. Each interior angle of a polygon can be calculated using the formula (n - 2) * 180° / n. In this case, we are given that the sum of the interior angles is 540 degrees.
So, we can set up the equation:
(n - 2) * 180° / n * n = 540°
Simplifying the equation:
(n - 2) * 180° = 540°
(n - 2) = 540° / 180°
(n - 2) = 3
Solving for n:
n = 3 + 2
n = 5
Now that we know the polygon has 5 sides, we can find the measure of x by substituting it back into the formula:
x = (5 - 2) * 180° / 5
x = 3 * 180° / 5
x = 540° / 5
x = 108°
In conclusion, the measure of x is 108 degrees, and each of the unknown angles in the polygon would also be 108 degrees since all angles in a regular polygon are equal.

To find the probability that a randomly selected student got an A in math or art class (or both), we need to use the principle of inclusion-exclusion.
Let's define the events:
M = Getting an A in math class
A = Getting an A in art class
We are given the following information:
n(M) = 82 (number of students who got an A in math)
n(A) = 73 (number of students who got an A in art)
n(M ∩ A) = 42 (number of students who got an A in both math and art)
To calculate the probability of getting an A in math or art class (or both), we can use the formula:
P(M ∪ A) = P(M) + P(A) - P(M ∩ A)
We need to find the probabilities P(M) and P(A) first.
P(M) = n(M) / total number of students
P(M) = 82 / 500
P(M) = 0.164
P(A) = n(A) / total number of students
P(A) = 73 / 500
P(A) = 0.146
Now, we can calculate the probability of getting an A in math or art class (or both):
P(M ∪ A) = P(M) + P(A) - P(M ∩ A)
P(M ∪ A) = 0.164 + 0.146 - (42 / 500)
P(M ∪ A) ≈ 0.164 + 0.146 - 0.084
P(M ∪ A) ≈ 0.226

Look for Relationships Chris is buying material
for an art project. Two stores have the material she
needs. Compare prices to find which material is the
better value. Explain.
To compare the prices and determine which material offers better value, Chris needs to consider several factors beyond just the price. Here are some key points to consider:
Quality: Compare the quality of the materials offered by both stores. Sometimes, a higher-priced material may offer better quality, durability, or performance, making it a better value in the long run.
Quantity: Check the quantity or size of the materials available for the price. If one store offers a larger quantity or size for a slightly higher price, it might be a better value as it provides more material for the money.
Features: Look for any additional features or benefits offered by the materials. For example, if one material includes extra accessories or tools at a slightly higher price, it may be a better value due to the added value and convenience.
Customer reviews: Research online or ask for recommendations from others who have used the materials from both stores. Their experiences and feedback can provide insights into the overall value and performance of the materials.
By considering these factors, Chris can make an informed decision and choose the material that offers the best overall value for her art project.

A drawing of a cereal box, as shown, has a scale of 1 inch to 1 foot.
What is the actual height, in inches, of the cereal box?
The actual height of the cereal box is 12 inches.
In the given scale of 1 inch to 1 foot, it means that every 1 inch on the drawing represents 1 foot in reality. Since there are 12 inches in a foot, the height of the cereal box in inches can be determined by multiplying the height shown on the drawing by 12.0
As a result, the actual height of the cereal box can be calculated by multiplying the height of the cereal box on the drawing by 12. For example, if the height of the cereal box on the drawing is 1 inch, then the actual height of the cereal box would be 1 inch multiplied by 12, which equals 12 inches.
Therefore, in this case, the actual height of the cereal box is 12 inches.

the example of a permutation is: A) The number of ways 3 people can win 3 different prizes.
A) The number of ways 3 people can win 3 different prizes.
This scenario involves the arrangement of 3 people winning 3 different prizes. Since the order in which the people win the prizes matters, this is an example of a permutation. For instance, if we have three people named A, B, and C, the possible permutations of them winning the prizes could be A winning the first prize, B winning the second prize, and C winning the third prize. Therefore, option A is an example of a permutation.

This month's blend used three times as many pounds of Type B coffee as Type A, for a total cost of $ 796. 0. How many pounds of Type A coffee were used?.
The cost Type A coffee were used in the blend 40 pounds .
assume the number of pounds of Type A coffee used is 'x'.
Given:
Cost of Type A coffee = $5.95 per pound
Cost of Type B coffee = $4.65 per pound
Total cost of the blend = $796.0
The blend used three times as many pounds of Type B coffee as Type A.
set up the equation to represent the total cost:
Total cost = Cost of Type A coffee + Cost of Type B coffee
$796.0 = $5.95 × x + $4.65 × (3x)
Simplifying the equation:
$796.0 = $5.95x + $13.95x
Combining like terms:
$796.0 = $19.9x
Dividing both sides by $19.9:
x = $796.0 / $19.9

Jadah takes the bus to school every morning. 3 out of the last 5 days last week, her bus was late. Based on those results, in how many out of the 180 school days would you expect her bus would be late?
Based on the given information, we can expect Jadah's bus to be late for approximately 108 out of the 180 school days.
To determine the expected number of days Jadah's bus would be late out of 180 school days, we can use the proportion of late days from the previous week.
Out of the last 5 days, her bus was late for 3 days. This can be represented as a ratio: 3/5.
To find the expected number of late days out of 180 school days, we can set up a proportion:
(3/5) = x/180
Cross-multiplying, we get:
5x = 3 * 180
5x = 540
x = 540/5
x = 108
Therefore, based on the results from the previous week, we can expect Jadah's bus to be late for approximately 108 out of the 180 school days.

$540 in an account growing at a rate allowing the money to double every 9 years. How much money would be in the account after 21 years, to the nearest dollar?
After 21 years, the amount in the account would be approximately $2160 to the nearest dollar.
To find out how much money would be in the account after 21 years, we can use the concept of compound interest.
Given that the money in the account doubles every 9 years, we can calculate the number of doubling periods within 21 years:
Number of doubling periods = 21 years / 9 years = 2.333 (approximately)
Since we can't have a fraction of a doubling period, we need to consider that there are 2 doubling periods within 21 years.
Now, let's calculate the final amount in the account using the formula for compound interest:
Final amount = Initial amount * (1 + interest rate)^(number of doubling periods)
In this case, the initial amount is $540 and the interest rate is 100% because the money doubles. The number of doubling periods is 2.
Final amount = $540 * (1 + 1)^(2)
Final amount = $540 * (2)^2
Final amount = $540 * 4
Final amount = $2160
Therefore, after 21 years, the amount in the account would be approximately $2160 to the nearest dollar.

Which aspect of Edgar’s investment in Cawh Consolidated Bank offers a greater percent yield, and how much greater is it? a. The stocks have a yield 6. 43 percentage points greater than that of the bonds. B. The stocks have a yield 6. 84 percentage points greater than that of the bonds. C. The bonds have a yield 1. 05 percentage points greater than that of the stocks. D. The bonds have a yield 9. 13 percentage points higher than that of the stocks.
The stocks of Cawh Consolidated Bank offer a yield that is 6.84 percentage points greater than that of the bonds.
To compare the yields of Edgar's investment in Cawh Consolidated Bank stocks and bonds, we need to calculate the yields of both investments and then find the difference between them.
For the stocks, the yield can be calculated by dividing the annual dividend per share by the purchase price per share and multiplying by 100. In this case, the yield of the stocks is [tex][{\frac{3.15}{21.38}] *100= 14.71 \%.[/tex]
For the bonds, the yield is the annual interest payment divided by the market value of the bonds, multiplied by 100. The yield of the bonds is [tex][{\frac{8.3}{105.166}]* 100 = 7.89 \%[/tex] .
Now, to determine which aspect of Edgar's investment offers a greater percent yield, we find the difference between the yield of the stocks and the yield of the bonds. The difference is [tex]14.71 \% - 7.89 \% = 6.82 \%[/tex].
