The approximate distance from the pool to the tennis courts is:

                    C)  3.35 miles

It is given that:

On a coordinate grid, a park is located at (3,0) ande the pool is located at (-3,3).

The tennis courts are the midpoint between the park and the pool.

This means that the distance from the pool to the tennis court is half the distance between the pool and the park.

The distance between pool and park is calculated by using the distance formula as follows:

[tex]Distance\ between\ pool\ and\ park=\sqrt{(3-(-3))^2+(0-3)^2}\\\\Distance\ between\ pool\ and\ park=\sqrt{(3+3)^2+(-3)^2}\\\\i.e.\\\\Distance\ between\ pool\ and\ park=\sqrt{6^2+3^2}\\\\i.e.\\\\Distance\ between\ pool\ and\ park=\sqrt{36+9}\\\\i.e.\\\\Distance\ between\ pool\ and\ park=\sqrt{45}\\\\i.e.\\\\Distance\ between\ pool\ and\ park=3\sqrt{5}\\\\i.e.\\\\Distance\ between\ pool\ and\ park=6.7082\ units[/tex]

Hence,

[tex]Distance\ from\ pool\ to\ tennis\ court=\dfrac{6.7082}{2}\\\\i.e.\\\\Distance\ from\ pool\ to\ tennis\ court=3.3541\ units[/tex]

Now, it is given that:

   1 unit= 1 mile

Hence, 3.3541 unit=3.3541 miles.

Hence, the answer is: Option: C

-37 + n = -56

Solving

-37 + n = -56

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '37' to each side of the equation.

-37 + 37 + n = -56 + 37

Combine like terms: -37 + 37 = 0

0 + n = -56 + 37

n = -56 + 37

Combine like terms: -56 + 37 = -19

n = -19

Simplifying

n = -19

Answer:

N=-19

Step-by-step explanation:

i think they were multiplying each by 4. so 6x4 would be 24. and 12x4 = 48, then 15x4= 60. so i believe the blanks are 24,12,60.

Answer:

x    y

6  24

9  36

12 48

15  60

Step-by-step explanation:

We need to find the rate of change in the table.

Lets start with the x-values.

6 to 9?

9 - 6 = 3

So, the rate of change in the x-value is 3

9 to 3 is 12

12 to 3 is 15

Now let's go onto the y-values.

We don't know the first number, so let's move to the next number, 36.

36 to 48?

48 - 36 = 12

Therefore, the rate of change in the y-value is 12

So, let's work backwards to find the first number.

36 - 12 = 24

48 + 12 = 60

Another easier way you could do it (really simple).

9 times what is 36?

9 x 4 = 36, right?

So, the change of rate is 4

So multiply everything in the x column by 4.

6 x 4 = 24

15 x 4 = 60

Since we don't have one the x value for 48, divide it by 4 which is 12

Voilà ;)

The stem and leaf plot below could not represent "the weight of phonebooks, in pounds".

The stem-and-leaf plot you've provided represents a dataset, but without specific labels for the data points, it's challenging to definitively assign the plot to a particular category. However, we can analyze the options you've provided.

1. **Average number of inches of rain in June:** The data points don't seem to represent rainfall values. Rainfall would typically be measured in fractions or decimals, not whole numbers like 33.

2. **Height of plant seedlings, in inches:** This is a possibility, especially if the numbers represent the height of seedlings in inches. The decimal point represented by the key (3 | 5 means 3.5) supports this interpretation, indicating a measurement in inches.

3. **Weight of phonebooks, in pounds:** Phonebook weights are usually measured in pounds or ounces. The given numbers do not correspond to common weights and are unlikely to represent phonebook weights.

4. **Height of NBA basketball players, in meters:** NBA player heights are typically measured in feet and inches, not meters. Additionally, the provided numbers do not align with typical heights of NBA players.

Given the context of the data and the presence of the decimal point in the key, it's most likely that the stem-and-leaf plot represents the **height of plant seedlings, in inches.** This interpretation is consistent with the format of the data and the provided key, suggesting measurements in inches.

So, the correct answer is "the weight of phonebooks, in pounds".

Step-by-step explanation:

Of the 20 drinks sold, 8 were mochas, so

8/20 = 0.4 = 40% of the drinks they sold were mochas.

If the sold 95 drinks, then 95(0.4) = 38 of them would be mochas if the proportion stays the same

Answer:

40

Step-by-step explanation:

To find the least common denominator, you find the least common multiples of the denominators, which in this case is 20 and 8.

Tower method:

Start: |20, 8

4 |20, 8 -> 4 is a factor that 20 and 8 have in common

  5,   2   -> 20/4 = 5, 8/4 = 2, those numbers do not have a common factor.

4 * 5 * 2 = 40.

Answer: 1/8,1.9,0.14

Step-by-step explanation:

Answer:

0.019 (1.9%), 0.14, 0.125 (1/8)

Step-by-step explanation:

The equivalent expressions  of -36x+54y-90 are -18(2x - 3y + 5), 18(-2x + 3y - 5), and -2(18x - 27y + 45). So options (2), (4) and (5) are correct.

To determine which expressions are equivalent to -36x + 54y - 90, we'll distribute the coefficients and compare the resulting expressions.

Let's start by distributing each expression:

1. -9(4x - 6y - 10) = -36x + 54y + 90

2. -18(2x - 3y + 5) = -36x + 54y - 90

3. -6(6x + 9y - 15) = -36x - 54y + 90

4. 18(-2x + 3y - 5) = -36x + 54y - 90

5. -2(18x - 27y + 45) = -36x + 54y - 90

6. 2(-18x + 54y - 90) = -36x + 108y - 180

Among these, expressions 2, 4, and 5 result in the same expression as -36x + 54y - 90.

Expression 2 is -18(2x - 3y + 5), expression 4 is 18(-2x + 3y - 5), and expression 5 is -2(18x - 27y + 45).

Therefore, the equivalent expressions are -18(2x - 3y + 5), 18(-2x + 3y - 5), and -2(18x - 27y + 45).

3x18(HxL)

multiply each equations answer by 2, because the opposite face is the same.

108x2=216

18x2=36

54x2=108

add these together to get 360 cm squared.

The surface area of the box is 360 cm².

To find the surface area of the rectangular prism, we need to find the areas of all the sides and add them together.

The formula to find the surface area is:

Surface Area = 2lw + 2lh + 2wh

Plugging in the given dimensions:

Surface Area = 2(18)(6) + 2(18)(3) + 2(6)(3) = 216 + 108 + 36 = 360 cm²

Therefore, the surface area of the box is 360 cm², which is option D.

[tex]\text{\bf{A.}}\quad b^8[/tex]

Step-by-step explanation:

It may be helpful to remember that an exponent signifies repeated multiplication:

Answer:

1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

Step-by-step explanation:

Given: Jamal Sliced aright circular cylinder into congruent pieces.

To find: Shape of Two-Dimensional plane section obtained after slicing.

We get congruent pieces only when we slice the cylinder parallel to its base at equal heights.

By doing this we get small pieces of cylinders of equal height and equal radius.

Base and top remains same that is circular in shape.

Therefore, 1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

Final answer:

When a right circular cylinder is sliced into two congruent pieces vertically through its axis, the resulting cross-section is a rectangle. If it is sliced perpendicularly to the axis, the cross-section is a circle.

Explanation:

If Jamal slices a right circular cylinder into two congruent pieces, the two-dimensional plane section that could result from the slice depends on the orientation of the cut. If he slices the cylinder vertically straight through its axis, the resulting cross-section will be a rectangle. If the slice is perpendicular to the axis of the cylinder, the cross-section will be a circle. It is not possible for a pentagon, hexagon, or triangle to result from slicing a right circular cylinder unless the cut is not straight or the surface of the cylinder is modified in some non-standard way, which is not suggested by the question.

Answer:

(B) and (D)

Step-by-step explanation:

A box plot or boxplot is a method for graphically depicting groups of numerical data through their quartiles.

Also, we know that in a box plot, the center is measured in the form of median and the spread can be measured in the form of Interquartile range which can be calculated by calculating the value of the upper and lower quartiles.

Thus, the best measure to find the center of the data represented in box plot is median and the best measure to find the spread is Interquartile range.

Hence, options B and D  are correct.

The more appropriate measures of center and spread for this data set include the following;

B. Better measure of spread: interquartile range (IQR).

D. Better measure of center: median.

In Mathematics and Geometry, a median refers to the middle number (center) of a sorted data set, which is when the data set is either arranged in a descending order from the greatest to least or an ascending order the least to greatest.

Generally speaking, the median is a better measure of center and for this data set, it is equal to 8. Additionally, the more appropriate measure of spread for this data set is the interquartile range (IQR);

Interquartile range (IQR) of data set = third quartile - first quartile

Interquartile range (IQR) of data set = 14 - 6

Interquartile range (IQR) of data set = 8.

Final answer:

To calculate the amount of blue paint Gabriella used, multiply 8.4 pints by 2/5 to determine the white paint, and then subtract this from the total, resulting in 5.04 pints of blue paint.

Explanation:

Gabriella uses a total of 8.4 pints of paint to paint her bedroom walls, with 2/5 of this amount being white paint. To find out how many pints of blue paint she used, we first need to determine the amount of white paint and then subtract that from the total.

Multiply the total amount of paint by 2/5 to find the white paint: 8.4 pints  imes 2/5 = 3.36 pints (white paint).

To find the blue paint, subtract the white paint from the total paint: 8.4 pints - 3.36 pints = 5.04 pints (blue paint).

Therefore, Gabriella used 5.04 pints of blue paint to paint her bedroom walls.

Answer:

x = 10

Step-by-step explanation:

8 + x =  6

11 + x     7

Cross Multiply

6(11 + x) = 7(8 + x)

66 + 6x = 56 + 7x

10 = x

The number that needs to be added to the numerator and denominator of 8/11 to result in 6/7 is 10.

The subject of the question is Mathematics, specifically algebra and fractions. We can represent the student's problem with an equation, where x stands for the unknown number to be added to the numerator and denominator of 8/11 to get 6/7.

The initial fraction is 8/11 and the desired fraction is 6/7. Hence, we can translate this problem into the equation: (8 + x)/(11 + x) = 6/7. By cross-multiplying to eliminate the fractions, we get: 7(8 + x) = 6(11 + x). Simplified, this equation becomes 56 + 7x = 66 + 6x. Solving for x, we subtract 6x from both sides: x = 66 - 56, so x = 10.

Step-by-step explanation:

[tex]\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\\text{We have the equation:}\ y=x^2+8x+6.\\\\a=1>0,\ \text{the parabola is o}\text{pen up.}\\\text{Therefore the function has the minimum in vertex}\\\\x^2+8x+6=x^2+2(x)(4)+6=x^2+2(x)(4)+4^2-4^2+6\\\\\text{use}\ (a+b)^2=a^2+2ab+b^2\to x^2+2(x)(4)+4^2=(x+4)^2\\\\y=(x+4)^2-16+6=(x+4)^2-10\to\text{vertex}\ (-4,\ -10).[/tex]

To determine the minimum value of the quadratic function x^2 + 8x + 6, we complete the square to get the expression (x + 4)^2 - 10 = 0. The function has a minimum value at (x, y) = (-4, -10), so the correct answer is D) minimum value at -10.

To find the maximum or minimum value of the quadratic function given by the expression x2 + 8x + 6, we need to complete the square. First, we will write the quadratic in the form of (x + h)2 + k, where h and k are constants.

The coefficient of x is 8. We take half of it, which is 4, and square it to get 16. Now add and subtract this square inside the quadratic expression:

x2 + 8x + 16 - 16 + 6 = 0

Now, group the perfect square trinomial and write it as a square of a binomial:

(x + 4)2 - 10 = 0

To find the minimum value, we set the squared term equal to zero, since the minimum value of a square is zero. As such, (x + 4)2 reaches its minimum value when x = -4, and the overall minimum value of the function is when k = -10. Because this is a quadratic with a positive leading coefficient, the function has a minimum value, not a maximum.

Therefore, the correct answer is D) minimum value at -10.
