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 ;)

Answer:

A picnic table is on sale for 40% off. The original price of the picnic table is

x =  $144.10

Step-by-step explanation:

If we have a 40% sale, that means

The price of the product will be its original price minus 0.4 multiplied by the original price

New price = (x) - 0.4*(x)

New price = 0.6*(x)

If the original price was $144.10

New price = 0.6*$144.10 = $86.46

Answer:

Rate = 10%

Step-by-step explanation:

We are given with the following details.

Interest earned = $ 116.25

Principal = $ 1550

Interest Rate = r (say)

Time = 9 months

         = [tex]\frac{9}{12} years[/tex]

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

[tex]Interest = Principal \times Rate \times time [/tex]

[tex]116.25=1550 \times r \times \frac{9}{12}[/tex]

[tex] r= \frac{116.25 \times 12}{1550 \times 9}[/tex]

r=0.1

Hence the r = 0.1

Hence the rate of interest is 10%

Answer:

8

Step-by-step explanation:

covert 8.4 into a fraction which would be 42/5

then subtract 42/5 from 2/5 and youll get 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.

Simplifying

-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

Answer:

[tex]\large\boxed{\text{ D) minimum value at -10}}[/tex]

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.

Answer: The integers are 23, 25, and 27

Step-by-step explanation:

Call the first integer n, and then the next two odd ones are n + 2 and n + 4.

Add them together to get 75:

n + n+ 2 + n + 4 = 75

which becomes 3n + 6 = 75

so 3n = 69, and n is therefore 23. n + 2 = 25, and n + 4 = 27.

The three consecutive odd integers whose sum is 75 are 23, 25, and 27. These are determined by forming an equation with the first odd integer as 'x' and the other two as 'x+2' and 'x+4', respectively, since consecutive odd numbers differ by 2.

The task is to find three consecutive odd integers whose sum is 75. To solve this, we can represent the three consecutive odd integers as x, x + 2, and x + 4. Since the sum of these integers is 75, we can set up the following equation: x + (x + 2) + (x + 4) = 75.

Simplifying the equation we get:
3x + 6 = 75
3x = 69
x = 23

Now we have our first integer x = 23. The next consecutive odd integer would be x + 2 which is 25, and the third one would be x + 4 which is 27. Therefore, the three consecutive odd integers that sum up to 75 are 23, 25, and 27.

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".

To rewrite the expression ln(9) = y as an exponential function, we can use the inverse relationship between logarithmic and exponential functions.

To transform the logarithmic equation ln(9) = y into an exponential form, recall the fundamental logarithm property: ln(x) = y can be expressed as e^y = x when using base 'e'. Applying this principle to our equation, ln(9) = y becomes e^y = 9. This represents the exponential function equivalent of the original logarithmic equation, where y is the exponent that, when applied to the base 'e', yields the result of 9. This conversion helps us understand the relationship between logarithmic and exponential expressions.

Final answer:

The square roots of 400 are represented by A) 400^1/2, C) -20, and E) 20. These correspond to the positive and negative values that, when squared, result in 400. Options B) 40, D) 10, and F) -400^1/2 do not square to 400 and are therefore incorrect.

Explanation:

To find the square roots of the number 400, we look for numbers that when multiplied by themselves will equal 400. The square root of a number can be both positive and negative since both will square to give the original number.

Option A (400^1/2) represents the principal square root of 400, which is found by raising 400 to the power of 0.5. This is equal to 20, so option A is correct.

Option B (40) is not a square root of 400 because 40 * 40 equals 1600, not 400.

Option C (-20) is the negative square root of 400 because (-20) * (-20) equals 400, so option C is correct.

Option D (10) is incorrect because 10 * 10 equals 100, not 400.

Option E (20) is the positive square root of 400, so this is correct.

Option F (-400^1/2) is the negative principal square root of -400. Since 400 is positive, this option is not applicable, so option F is incorrect.
