Jeannie Kevin scored 9 points , The method of breaking an addend to make a ten is a technique to help children learn mental math when they are working on addition problems that are not convenient to do with the traditional algorithm. Children can apply this method to breaking down numbers that are near ten, such as 8 and 9.
The breaking addends method works by breaking one of the addends into two parts, one that can be combined with the other addend to make ten and the remaining part can be added to the answer.
For example, to break apart the addend 8 to make ten when solving the problem 8 + 7, we can break 8 into two parts: 2 and 6. Then we can add the 2 to 7 to get 9 and add the remaining 6 to the 9 to get 15. Therefore, 8 + 7 = 15. In this problem, we do not need to break apart any addends because we have a ten in the problem.
If we separate the ten and the 1, we can see that Jeannie scored 9 points.

$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.

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°

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.

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
Therefore, the probability that a randomly selected student got an A in math or art class (or both) is approximately 0.226, or 22.6%.

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.

$16000 is invested for 5 years with an APR of3 % and quarterly compounding
The accumulated value in 5 years of the investment compounded quarterly is approximately: $18578.946
How to find the compound interest?Compound interest differs from simple interest in that the interest received in one period will itself accrue in the next period. As a result, the amount in the account increases exponentially.
The future value of a compounding account depends on the number of compounding periods per year. Another factor is the annual interest rate. The higher the APR, the greater the cumulative value over time.
The formula for compound interest is:
FV = P(1 + (r/m))^(mt)
where:
FV is the future value of the investment.
P is the principal or initial amount invested.
r is the annual interest rate.
m is the number of compounding per year.
t is the time in years,
P = $16000
t = 5
m = 4
r = 3% = 0.03
Thus:
FV = 16000(1 + (0.03/4))^(4 * 5)
FV = $18578.946

A sample of n = 5 scores has a mean of M = 12. If one person with a score of X = 18 is added to the sample, what is the value for the new mean?.
A sample of n = 5 scores has a mean of M = 12. If one person with a score of X = 18 is added to the sample, the new mean, can be calculated as 14.
The initial sample of n = 5 scores has a mean of M = 12. To find the new mean after adding a score of X = 18 to the sample, we can use the formula for the mean: M = (sum of scores) / (number of scores).
The sum of the original scores is 5 * 12 = 60. When we add the score of 18, the new sum becomes 60 + 18 = 78. Since the total number of scores is now 6, the new mean is calculated as 78 / 6 = 13.
Therefore, the new mean after adding a score of 18 to the sample is 14.

You have 8 teaspoons of sugar. It takes 1 teaspoons of sugar to make 36 cupcakes. The function `t\left(s\right)=36s`represents the number of cupcakes c, that can be made with t teaspoons of sugar. What domain and range are reasonable for the function?
For the given function t(s) = 36s, let's determine the domain and range:
Domain:
The domain of a function refers to the set of possible values for the independent variable (sugar teaspoons in this case). Since the number of teaspoons of sugar cannot be negative, the domain is all non-negative real numbers. Therefore, the domain is represented as s ≥ 0, indicating that s must be greater than or equal to 0.
Range:
The range of a function refers to the set of possible values for the dependent variable (number of cupcakes in this case). The number of cupcakes cannot be negative, and it can be any whole number since it represents a count. Therefore, the range is all non-negative integers. It can be represented as[tex]t(s) = {0, 1, 2, 3, ...},[/tex] indicating that the number of cupcakes can be 0, 1, 2, 3, and so on.
Hence, the domain for the function is s ≥ 0 and the range is[tex]t(s) = {0, 1, 2, 3, ...}.:[/tex]

david wants to install a fence around his garden. what is the total cost of fencing?
The total cost of fencing to David, based on the dimensions of the fence would be $ 996.
How to find the cost of fencing ?Since the area of a rectangle is length times width, the other side must be:
240 sq ft / 12 ft
= 20 ft
For the side along the street (12 feet), using the more expensive fencing ($18 per linear foot):
Cost = 12 ft x $18/ft
= $216
For the other three sides (two sides of 20 feet and one of 12 feet), using the less expensive fencing ($15 per linear foot):
Cost = (20 ft + 20 ft + 12 ft) x $15/ft
= 52 ft x $15/ft
= $780
So, the total cost for the fencing will be:
Total cost = Cost of expensive fencing + Cost of less expensive fencing
Total cost = $216 + $780
= $996

If mWVX = (13x + 9)° and mZWXZ = (5x + 36)°, find mZWXY
The value of mZWXY is 103.5° , mWVX = (13x + 9)° and mZWXZ = (5x + 36)°
To find: mZWXY
Here, mWVX and mZWXY are two angles that are formed when the two parallel lines are intersected by a transversal. Therefore,mWVX = mZWXY (alternate interior angles)
and mZWXZ is the third angle that is formed and the sum of the three angles is equal to 180°.
So,mWVX + mZWXY + mZWXZ = 180°
Therefore,mZWXY + mZWXY + (5x + 36)°
= 180°13x + 9 + (5x + 36)°
= 180°18x + 45
= 180°18x
= 180° - 45x
= 135/18x = 7.5
Therefore, mZWXY = mWVX= (13 × 7.5 + 9)°= 103.5°
Hence, the value of mZWXY is 103.5°.
