The ratio of Student Ambassadors to total Students in Mr. Thompson's class is 1:4.

Ratios and proportions are two fundamental concepts in mathematics that are used to compare quantities and express relationships between them.

A ratio is a comparison of two quantities that are expressed in the same units. Ratios are typically written in the form of "a:b" or "a to b", where a and b are two quantities being compared. For example, the ratio of the number of boys to the number of girls in a class of 20 students might be 3:2, indicating that there are 3 boys for every 2 girls.

A proportion is a statement that two ratios are equal. Proportions are used to solve problems involving ratios by setting up an equation that equates two ratios.

The total number of students in Mr. Thompson's class is 6 + 18 = 24.

The ratio of Student Ambassadors to total Students is 6:24, which can be simplified by dividing both the numerator and denominator by 6 to get 1:4.

Therefore, the ratio of Student ambassadors to total Students in Mr. Thompson's class is 1:4.

Answer:

C.  ∠B ≅∠E

Step-by-step explanation:

Since ΔJAB ≅ ΔFED, their corresponding angles are congruent.

Therefore:

Given that m∠BJA = 52° and m∠EDF = 65°, then:

Therefore, m∠ABJ = 65°.

Interior angles in a triangle sum to 180°. Therefore:

⇒ m∠JAB + m∠BJA + m∠ABJ = 180°

⇒ m∠JAB + 52° + 65° = 180°

⇒ m∠JAB + 117° = 180°

⇒ m∠JAB = 63°

As m∠JAB = m∠FED, then m∠FED = 63°.

Since ΔJAB ≅ ΔFED, their corresponding sides are congruent.

Given that AB = 10 inches, then ED = 10 inches.

Therefore, the statement that is not true is:

Option B is the actual length of the playground, which is 27 feet.

First, find the scale factor from the drawing to the actual playground. Since the width of the drawing is 2 inches and the actual width is 6 feet, the scale factor is:

6 feet / 2 inches = 3 feet/inch

Next, use this scale factor to find the actual length of the playground. The length in the drawing is 9 inches, so the actual length is:

9 inches x 3 feet/inch = 27 feet

Therefore, the actual length of the playground is 27 feet.

John Singer Sargent repainted the right strap on Madame X (1883-1884). The Option C is correct.

Madame X caused a scandal when it was first exhibited in Paris in 1884. Sargent had originally painted the right strap of the dress hanging off the shoulder which was seen as too provocative at the time.

However, he later repainted the strap to be more securely in place, but this change did not entirely satisfy critics, but, nevertheless, the painting is now considered a masterpiece and an iconic example of Sargent's style.

Answer:

Step-by-step explanation:

If the large Jar is $4.10 for 540g

and  small jar  $2.81 for 360 g

You need to show how much it cost for 1 g,so you can compare how much it cost per gram. You would divide the total cost by the grams to see how much it is for 1 g.

Large jar.   $4.10/540 = $.0076  for 1 gram

Small Jar.   $2.81/360 =$.0078 for 1 gram

Because the large jar is cheaper to buy per gram, the large jar is the best value for the money.

The function that is most likely increase exponentially is f(x). Because it eventually exceeds g(x)

To determine which function is most likely increasing exponentially, we need to compare the rate at which the two functions are increasing.

Looking at the table, we can see that as x increases, f(x) increases at a faster rate than g(x). In fact, f(x) eventually exceeds g(x) for x values greater than or equal to 5. This suggests that f(x) is increasing at an exponential rate.

On the other hand, g(x) is increasing at a much slower rate than f(x). Although g(x) is also increasing, it does not appear to be increasing exponentially. In fact, g(x) will never exceed f(x), because f(x) grows at a faster rate.

Therefore, the function that is most likely increase exponentially is f(x).

3/4w ≤ 24

We can isolate w by multiplying both sides by 4/3 (which is the reciprocal of 3/4), remembering to reverse the inequality because we're multiplying by a negative number:

w ≥ 24 × 4/3

w ≥ 32

So the solution to the inequality is w ≥ 32.

Suppose that ∑₁¹²⁴a₁ = -10 and  ∑₁¹²⁴b₁ = -20. We desire to compute the following ∑₁¹²⁴(29a₁ - 13b₁), we proceed as follows.

So, the summation ∑₁¹²⁴(29a₁ - 13b₁)

Expanding the brackets, we have that

∑₁¹²⁴(29a₁ - 13b₁) = ∑₁¹²⁴29a₁ -  ∑₁¹²⁴13b₁)

= 29∑₁¹²⁴a₁ -  13∑₁¹²⁴b₁

Given that ∑₁¹²⁴a₁ = -10 and  ∑₁¹²⁴b₁ = -20.

So, substituting the values of the variables into the equation, we have that

∑₁¹²⁴(29a₁ - 13b₁) = 29∑₁¹²⁴a₁ -  13∑₁¹²⁴b₁

= 29(-10) - 13(-20)

Answer:

The equation that shows how the cost of the baby shower, y, depends on the number of guests, x is:

y = 9x + 43

In this equation, x represents the number of guests and y represents the cost of the baby shower. The term 9x represents the cost of food for each guest, multiplied by the number of guests. The term 43 represents the cost of decorations that has already been spent. Therefore, the total cost of the baby shower can be calculated by multiplying the number of guests by the cost of food per guest and adding the cost of decorations that have already been spent.

Answer: y = 9x + 43

Step-by-step explanation: y =  cost of the baby shower

x = number of guests

$9 per guest would be 9x

Answer:

The correct answer is A.

Step-by-step explanation:

The correct answer is A.

To find the length of one side of the square, we need to take the square root of the area. Therefore, the square root of 90 is approximately 9.49 feet. Since this value falls between 9 feet and 10 feet, but is closer to 9 feet, the statement "√90 feet is between 9 feet and 10 feet but is closer to 9 feet" is true. So, Jimmy should cut the carpet to 9.49 feet to fit the square-shaped room.

If the market requires a return of 15% on assets of this risk, the stock should be selling for $3.92.

We can calculate the stock price using the dividend discount model with the following formula: "Stock Price = Dividend / (Required Rate of Return - Dividend Growth Rate)".

Data:

Dividend =  $0.50

Increase its dividend by 2% per year.

The next dividend (D1) can be calculated as:

D1 = D0 x (1 + Dividend Growth Rate)

D1 = $0.50 x (1 + 0.02)

D1 = $0.51

Using these values, we can calculate the stock price as follows:

= $0.51 / (0.15 - 0.02)

= $0.51 / 0.13

= $3.92.

According to the information, the least number of committees that need to be formed to meet all of the conditions is 8.

To minimize the number of committees, we can try to use each student in as many committees as possible. Since each student must be in exactly 2 committees, and there are 12 students, we need a total of 24 "student committee slots".

Now we need to figure out how to assign the students to committees so that no two committees have more than one student in common. One way to do this is to use a "round-robin" approach:

Assign the first student to committees 1, 2, and 3.

For the next student, assign them to committees 1, 4, and 5.

For the third student, assign them to committees 2, 4, and 6.

Continue in this way, cycling through the remaining students and assigning them to three committees at a time, making sure to avoid any duplicates.

The local minima are 1 and -2

The values at which the function f has a local minimum are -3 and 4

Step-by-step explanation:

Main Concepts:

Brief side-discussion about local vs global minimums

Concept 1. What a Local minimum is

Concept 2. Where a local minimum is at

Brief side-discussion:  a Local minimum  vs  Absolute or Global minimum

A local minimum is the height of any "low" point on a continuous section of the function where all of the points "near" it are higher.

In contrast, an Absolute minimum (sometimes called a "global minimum"), is the lowest height the function ever reaches.

Concept 1. What a Local minimum is

This problem is asking about local minimums, of which there are two:

"The Local minimum value" itself IS the height of the point (the "y"-value).

The point on the left has coordinates (-3,1), and the point on the right has coordinates (4,-2).

So, the local minima are 1 and -2

Concept 2. Where a local minimum is at

The minima are different from "The values AT which the function has a local minimum" which is the input (or, "x"-value) that will produce that output when put into the function.

So, the values at which the function f has a local minimum are -3 and 4

Answer:

87.9646 millimeters.

Step-by-step explanation:

The circumference (C) of a circle is given by the formula:

C = πd

Where d is the diameter of the circle and π (pi) is a mathematical constant approximately equal to: 3.14159.

In this case, the diameter of the circle is given as 28 millimeters, so we can substitute this value into the formula to find the circumference:

C = πd = π(28 mm) = 87.9646 mm (rounded to 4 decimal places)

Therefore, the circumference of the circle is approximately 87.9646 millimeters.
