The Addition Property of Equality allows us to add EF to both sides of the equation without changing its truth, giving us AB + EF = CD + EF.

We have,

The Addition Property of Equality states that if we add the same quantity to both sides of an equation, the equation remains true.

In the given equation,

AB = CD, we can add the same quantity, EF, to both sides of the equation to obtain:

AB + EF = CD + EF

This is because if two quantities are equal, and we add the same amount to both of them, the result is still equal.

Therefore,

The Addition Property of Equality allows us to add EF to both sides of the equation without changing its truth, giving us AB + EF = CD + EF.

Answer:

The answer to (m+3)(m-3) is m^2-9.

Step-by-step explanation:

We will use distributive law to solve this question.

m(m-3)+3(m-3)

= m^2-3m+3m-9

= m^2-9 (since, 3m-3m=0)

As an alternative method, we can use the direct rule learned in algebra: (a+b)(a-b)=a^2-b^2.

so, here a=m and b=3.

(m+3)(m-3)

=m^2-3^2

=m^2-9

The average number of hours worked in the previous week for adults in the country is likely to be between 38.4 and 43.5 hours.

Based on the survey results of 1500 adults, we can be 95% confident that the true mean number of hours worked in the previous week for the entire population of the country lies between 38.4 hours and 43.5 hours.

This means that if we were to repeat this survey multiple times, 95% of the time the sample mean would fall within this range. Therefore, we can conclude that the average number of hours worked in the previous week for adults in the country is likely to be between 38.4 and 43.5 hours.

The ceiling function, denoted by ⌈x⌉, gives the smallest integer that is greater than or equal to x. Therefore, ⌈-0.75⌉ is the smallest integer that is greater than or equal to -0.75.

Since -1 is the smallest integer that is greater than or equal to -0.75, we have:

⌈-0.75⌉ = -1

Therefore, the functional value for the ceiling function at -0.75 is -1.

The value of the function when the quantity f divided by g of 8 is given by option D. 5.

The function are equal to,

f(x) = 3x + 1

g(x) = x - 3

The expression 'f divided by g of 8' means it is required to evaluate the function f(x) divided by g(x) at x=8.

First, find the individual values of function  f(8) and g(8) is equal to,

f(x) = 3x + 1

Substitute the value of x = 8 we get,

⇒ f(8) = 3(8) + 1

⇒ f(8) = 25

Now, for the function g(x),

g(x) = x - 3

Substitute the value of x = 8 we get,

⇒ g(8) = 8 - 3

⇒ g(8) = 5

Then, we can find the value of f(x) divided by g(x) at x=8 which is equal to,

f(x) / g(x)

= ( 3x + 1 )/ ( x - 3 )

= f(8) / g(8)

= 25 / 5

= 5

Therefore, the quantity function f divided by g of 8 is 5, which is option (D).

The polar form of the rectangular coordinates (-√√2, -√2) is (2√(1 + √2), 15π/28)

To convert the rectangular coordinates (-√√2, -√2) into polar form, we first need to find the value of r (the radius) and θ (the angle).

r = √((-√√2)^2 + (-√2)^2) = √(2 + 2√2) = 2√(1 + √2)

To find the value of θ, we can use the following formula:

θ = atan(y/x)

where atan is the inverse tangent function, and (x, y) are the rectangular coordinates.

θ = atan(-√2/(-√√2)) = atan(√2) = π/4 radians

However, we need to express the angle in terms of 7 over the interval 0 ≤ θ < 2π/7, with a positive value of r.

To do this, we can add a multiple of 2π/7 to the value of θ until we get an angle in the desired interval.

θ = π/4 + 2π/7 = (7π + 8π)/28 = 15π/28 radians

Therefore , the solution of the given problem of percentage comes out to be  14 gallons of the first brand and 56 gallons of the second brand must be utilised.

In statistics, a figure or metric than may be presented as a percentage or 100 is denoted by the abbreviation "a%". Another unusual spelling is "pct," "pct," and "pc." The percent symbol ("%") is the method that is most usually used for this. Additionally, there are no indications or predetermined ratios of any component to the whole. Numbers are effectively integers since they frequently add up to 100.

Here,

Let's write "x" for the first brand's (35% pure antifreeze) number of gallons and "y" for the second brand's (60% pure antifreeze) number of gallons.

Given:

70 gallons of mixture are required in total.

Desired antifreeze content in the combination is 55%

Based on the information provided, we can construct the following system of equations:

=> Equation 1: x + y = 70

=> Equation 2: 0.5*70 = 0.55x + 0.60y

=> x = 70 - y

=> 0.35(70 - y) + 0.60y = 0.55 * 70

=> 24.5 - 0.35y + 0.60y = 38.5

=> 0.25y = 14

=> y = 56

=> x = 70 - 56

=> x = 14

In order to get 70 gallons of a mixture that contains 55% pure antifreeze, 14 gallons of the first brand and 56 gallons of the second brand must be utilised.

The solution of missing sides and angle  is:  A = 60°, B = 34.8°, C = 85.2°  a = 4, b = 5, c = √21

Trigonometric functions are used to obtain unknown angles and distances from known or measured angles in geometric drawings.

Basics of Trigonometry deals with measuring angles and problems related to angles. There are six basic trigonometric ratios: sine, cosine, tangent, cosecant, secant, and cotangent. All  important trigonometric concepts  are based on these trigonometric relationships or functions.

Solving a triangle means determining all  its angles and sides. In this case, we are given angle A and sides a and b, and we want to find the remaining angles and sides.

First, we can use the law of cosines c to find the third side:

c² = a²+ b² - 2ab cos(A)

c² = 4² + 5² – 2(4)(5) cos(60)

c² = 16 + 25 - 40 cos (60)

c² = 41-20

c² = 21

c = √21

Now that we have all three sides, we can use the law of cosines to find the remaining angles:

cos(B) = (a²+ c² – b²) / (2ac)

cos(B) = (4²  +(√21)² – 5²) / (2(4) (√21))

cos(B) = (16 + 21 - 25) / (8√21)

cos(B) = 12 / (8√21)

B = cos⁻¹ (12 / (8√21))

cos(C) = (a²+ b² – c²) / (2ab)

cos(C) = (4² + 5² – (√21)²) / (2(4)(5))

cos(C) = (16 + 25 - 21) / 40

cos(C) = 20/40

C = cos⁻¹ (20/40)

Simplifying  trigonometric functions:

B ≈ 34.8°

C = 85.2°

Therefore, the solution is:

A = 60°, B = 34.8°, C = 85.2°

a = 4, b = 5, c = √21

The correct option is C. mean, that is Mr. Greene should use the mean temperature, which is 77.86°F.

In mathematics, the mean value is a measure of central tendency of a set of numbers. It is also known as the arithmetic mean and is found by adding all the numbers in a set and dividing the sum by the total number of values. The mean is commonly used to represent the typical or average value of a set of data. It is a useful tool in statistics and other branches of mathematics for analyzing data and making predictions. The mean value can be affected by outliers or extreme values in a set of data, which can skew the results. However, in many cases, the mean provides a reliable and useful measure of central tendency.

Mr. Greene should use the mean temperature, which is 77.86°F, to summarize the temperatures for each day. The mean is a good measure of central tendency when the data set is approximately symmetric and has no significant outliers, which appears to be the case here. Additionally, using the mean will provide a single number that is representative of the entire data set. The interquartile range and mean absolute deviation are measures of spread and do not provide a summary of the temperatures for each day, and the maximum temperature is just one value and may not be representative of the entire data set.

The total amount Debra ended up paying for the equipment was $28,541.60 and the amount of interest Debra paid on the loan was $14,041.60

(a) To find the total amount Debra ended up paying for the equipment (including the down payment and monthly payments), we need to add the down payment to the total amount of the loan, and then add the total amount of the monthly payments made over the two years.

Total amount of the loan = $14,500 - $1,300 (down payment) = $13,200

Total amount paid = Down payment + Total amount of the loan + Total amount of monthly payments

Total amount paid = $1,300 + $13,200 + ($585.04 x 24) [since there are 24 monthly payments in 2 years]

Total amount paid = $1,300 + $13,200 + $14,041.60

Total amount paid = $28,541.60

Therefore, the total amount Debra ended up paying for the equipment (including the down payment and monthly payments) was $28,541.60.

(b) To find the amount of interest paid on the loan, we need to subtract the total amount borrowed from the total amount paid, and then subtract the down payment. This will give us the total amount of interest paid over the two years.

Total interest paid = Total amount paid - Total amount borrowed - Down payment

Total interest paid = $28,541.60 - $13,200 - $1,300

Total interest paid = $14,041.60

Therefore, the amount of interest Debra paid on the loan was $14,041.60.
