Whitney needs 5/4 cup of sugar in total to bake all the brownies.

To calculate the total amount of sugar needed to bake all the brownies, we need to add the quantities of sugar required for each type of brownie.

According to the information given, one type of brownie requires 1/2 cup of sugar and the other type requires 3/4 cup of sugar.

To find the total amount of sugar needed, we add these two quantities:

1/2 cup + 3/4 cup

To add fractions, we need to have a common denominator.

The common denominator is 4:

(1/2) x (2/2) cup + (3/4) x (4/4) cup

This simplifies to:

2/4 cup + 12/16 cup

Now, we can add the fractions:

(2/4) cup + (12/16) cup = (4/8) cup + (12/16) cup

Next, we find a common denominator, which is 16:

(4/8) x (2/2) cup + (12/16) x (1/1) cup

This simplifies to:

8/16 cup + 12/16 cup

Finally, we add the fractions:

8/16 cup + 12/16 cup = 20/16 cup

Since 20/16 is an improper fraction, we can simplify it by dividing both the numerator and denominator by their greatest common divisor, which is 4:

(20/4)/(16/4) cup = 5/4 cup

The result obtained by adding the three digits is 17.

Let's denote the three-digit number as XYZ, where X, Y, and Z represent the individual digits.

Given that the product of the three digits is 135, we have the equation

X × Y × Z = 135.

To find the result obtained by adding the three digits (X + Y + Z), we need to determine the individual values of X, Y, and Z that satisfy the given equation.

We can start by listing all possible combinations of three digits that multiply to 135:

1 × 3 × 45

1 × 5 × 27

1 × 9 × 15

3 × 5 × 9

Out of these combinations, we can observe that the sum of the digits in each combination is:

1 + 3 + 45 = 49

1 + 5 + 27 = 33

1 + 9 + 15 = 25

3 + 5 + 9 = 17

Therefore, the result obtained by adding the three digits is 17.

In conclusion, by adding the three digits of the three-digit number, we get the result of 17.

The coordinates of the vertices after a dilation with a scale factor of 1/3 considered at the origin include:

Q' (-3, -3).

R' (1, -3).

S' (3, 3).

T' (-1, 3).

In Geometry, a dilation is a type of transformation which typically changes the side lengths of a geometric object, but not its shape.

In this scenario and exercise, we would dilate the coordinates of the vertices by applying a scale factor of 1/3 that is centered at the origin as follows:

Coordinate Q (-9, -9) → Q' (-9 × 1/3, -9 × 1/3) = Coordinate Q' (-3, -3).

Coordinate R (3, -9) → R' (3 × 1/3, -9 × 1/3) = Coordinate R' (1, -3).

Coordinate S (9, 9) → S' (9 × 1/3, 9 × 1/3) = Coordinate S' (3, 3).

To find the probability that two distinct numbers chosen randomly from the set {-2, -6/5, -1/3, 0, 1/2, 5/6, 3} will be the slopes of two perpendicular lines, we need to determine the total number of possible pairs of distinct numbers and the number of pairs that result in perpendicular slopes.

Total number of possible pairs:

Since we are choosing two distinct numbers from a set of seven, the total number of possible pairs is given by the combination formula:

C(7, 2) = 7! / (2!(7 - 2)!) = 7! / (2! * 5!) = 21

Pairs resulting in perpendicular slopes:

For two lines to be perpendicular, the product of their slopes must be -1. So, we need to count the number of pairs whose product is -1.

The set contains two negative numbers {-2, -6/5} and one positive number {3}. None of these numbers have a reciprocal within the set that gives a product of -1. Therefore, no pairs can be formed from these numbers that result in perpendicular slopes.

Hence, the number of pairs resulting in perpendicular slopes is 0.

Therefore, the probability of randomly choosing two distinct numbers from the set {-2, -6/5, -1/3, 0, 1/2, 5/6, 3} that will be the slopes of two perpendicular lines is 0/21, which simplifies to 0.

Based on the line of best fit, the predicted price for the seller's house with a size of 2100 square feet is approximately $205.88.

In the given scenario, the seller has a house that is 2100 square feet. The line of best fit for the neighborhood comps is expressed as y = 0.074x + 50.48. Here, "x" represents the square footage of a house, and "y" represents the predicted price based on the square footage.

To determine the predicted price of the seller's house, we substitute the square footage (x) with 2100 in the equation:

y = 0.074 * 2100 + 50.48

Calculating the expression, we have:

y = 155.4 + 50.48

y = 205.88

Hence, the predicted price for the seller's house, based on the line of best fit, is approximately $205.88.

It's important to note that the line of best fit is derived from neighborhood comps and may not perfectly predict the actual price of the seller's house. It serves as an estimation based on the trend observed in the neighborhood.

To determine the best model for fitting the given data, we can analyze the trend and pattern in the population values over time. One common approach is to perform linear regression to find the equation of the line that best represents the data.

To find the regression equation, we'll use the given data points (t, P) as follows:

t: 0, 1, 2, 3, 4

P: 22.8, 25, 26.5, 27.1, 27.8

Using a calculator or statistical software, we can perform linear regression to find the equation of the line that best fits the data. The equation will have the form:

P = mt + b

where m represents the slope of the line and b represents the y-intercept.

Performing the regression calculation, we find that the equation of the line that best fits the data is approximately:

P = 1.155t + 22.625

To determine the year when the population will be less than 24,000, we can substitute P = 24 into the equation and solve for t:

24 = 1.155t + 22.625

1.155t = 24 - 22.625

1.155t = 1.375

t ≈ 1.19

Rounding to the nearest whole number, we find that the year when the population will be less than 24,000 is 1 (1997).

To find the population in 2008, we substitute t = 12 into the equation:

P = 1.155(12) + 22.625

P ≈ 36.18

Rounding to the nearest whole number, the estimated population in 2008 is 36,000.

In summary:

6) The linear regression equation that best fits the data is P = 1.155t + 22.625.

The population will be less than 24,000 in the year 1997.

The estimated population in 2008 is 36,000.

The reasoning for the third step of the proof is the SAS Triangle Congruence Theorem, which establishes the congruence of the two triangles involved.

In the given proof, we are trying to prove that AC is equal to ED in a rectangle ABCD. The reasoning for the third step of the proof can be explained as follows:

Statement 3: ZBAD = ZCDA

Reason: SAS Triangle Congruence Theorem

Explanation: The SAS (Side-Angle-Side) Triangle Congruence Theorem states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

In this case, we are considering triangles ZBA and ZDA. We know that AB is congruent to AD (statement 2, "AB & CD") and that the angles ZBA and ZDA are right angles since ABCD is a rectangle (statement 1, "Quadrilateral ABCD is a rectangle").

Therefore, by the SAS Triangle Congruence Theorem, we can conclude that triangle ZBA is congruent to triangle ZDA. And since corresponding parts of congruent triangles are congruent (CPCTC), we can say that angle ZBAD is congruent to angle ZCDA.

Answer: To calculate the expected value, we need to multiply each possible outcome by its probability and then add up the results.

The probability of selecting a gold marble is 3/41, the probability of selecting a silver marble is 8/41, and the probability of selecting a black marble is 30/41.

The winnings/losses associated with each outcome are $3 for gold, $2 for silver, and -$1 for black.

Step-by-step explanation:

Therefore, the expected value can be calculated as follows:

(3/41) x $3 + (8/41) x $2 + (30/41) x (-$1)

= $0.073

The expected value is $0.073, which means that on average, you can expect to win $0.073 per game if you play this game many times.

Therefore, if you play this game, you can expect to win a small amount of money on average, but it is not a guaranteed win.

Answer:

The area of a parallelogram is given by the formula:

Area = base * height

We are given that the area is 36 square meters and the height is 4 meters. Substituting these values into the formula, we get:

36 = base * 4

36 / 4 = base

9 = base

Therefore, the length of the base is 9 meters.

To simplify the given expression: 4x + 8 + (6x - 7) - (8x + 9), we can follow the order of operations (parentheses, exponents, multiplication and division, and addition and subtraction) to simplify it step by step.

First, let's simplify the expression inside the parentheses:

6x - 7 becomes 6x - 7

8x + 9 becomes 8x + 9

Now, let's simplify the entire expression:

4x + 8 + 6x - 7 - 8x - 9

Combining like terms:

(4x + 6x - 8x) + (8 - 7 - 9)

2x - 8

Therefore, the simplified form of the expression 4x + 8 + (6x - 7) - (8x + 9) is 2x - 8.

Answer:

y = 4.71 and y = -8.71

Step-by-step explanation:

Step 1:  Subtract 5 from both sides:

((y + 2)^2 + 5 = 50) - 5

(y + 2)^2 = 45

Step 2:  Take the square root of both sides, subtract 2 from both sides, and round to the nearest hundredth to solve for y.  

Positive answer:

√(y + 2)^2 = √45

(y + 2 = √45) - 2

y = √45 - 2

y = 4.708203932

y = 4.71

Thus, one answer for y (rounded to the nearest hundredth) is approximately 4.71.

Negative answer:

√(y + 2)^2 = -√45

(y + 2 = -√45) - 2

y = -√45 - 2

y = -8.708203932

y ≈ - 8.71

Thus, the other answer for y (rounded to the nearest hundredth) approximately. -8.71

Optional Step 3:  We can check our work by plugging in 4.71 and -8.71 for y and seeing whether we get 50.  Because they're rounded, you won't get exactly 50, but the answer should be close enough for us to trust our approximations:

Plugging in 4.71 for y:

(4.71 + 2)^2 + 5 = 50

(6.71)^2 + 5 = 50

45.0241 + 5 = 50

50.0241 > 50

Our answer is close enough to 50 that we can trust our approximation.

Plugging in -8.71 for y:

(-8.71 + 2)^2 + 5 = 50

(-6.71)^2 + 5 = 50

45.0241 + 5 = 50

50.0241 > 50

Again, our answer is close enough to 50 that we can trust our approximation.
