yes

Answer: She had added the Denominator, instead of finding the LCM.

Explanation: She should've multiplied them by a common number to equal a common Product, and replace the Denominator with the Product. (The correct denominator is 20, because 4 x 5 = 20, and 5 x 4= 20)

The solution set of the inequalities are,

1) x ∈ [15, ∞)

2) x ∈ (- ∞, 1]

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequalities are,

1) 3x + 7 ≤ 4x - 8

2) - 2x + 3 ≥ 1

Now, Simplify the inequality as;

1) 3x + 7 ≤ 4x - 8

⇒ 3x + 7 ≤ 4x - 8

⇒ 7 + 8 ≤ 4x - 3x

⇒ 15 ≤ x

⇒ x ∈ [15, ∞)

2) - 2x + 3 ≥ 1

⇒ - 2x + 3 ≥ 1

⇒ 3 - 1 ≥ 2x

⇒ 2 ≥ 2x

⇒ 1 ≥ x

⇒ x ∈ (- ∞, 1]

Answer:

1632 inches squared

Step-by-step explanation:

Hi!

So the formula for area is length times width.

So you would multiply the length by the width which is 34 times 48 to get the area which is 1632 in squared.

The relative frequency of landing on an egg, caterpillar, chrysalis and adults are 0.2, 0.24, 0.3 and 0.26.

"Relative frequency represents the ratio of the number of times a value of the data occurs in a dataset".

For the given situation,

Number of times egg landed on spin, x1 = 10

Number of times caterpillar landed on spin, x2 = 10

Number of times chrysalis landed on spin, x3 = 15

Number of times adult landed on spin, x4 = 13  

Total number of times, n  = 50

The formula for relative frequency =  [tex]\frac{x}{n}[/tex]

The relative frequency of landing on an egg = [tex]\frac{10}{50}[/tex]

⇒ [tex]0.2[/tex]

The relative frequency of landing on caterpillar = [tex]\frac{12}{50}[/tex]

⇒[tex]0.24[/tex]

The relative frequency of landing on chrysalis  = [tex]\frac{15}{50}[/tex]

⇒ [tex]0.3[/tex]

The relative frequency of landing on adults = [tex]\frac{13}{50}[/tex]

⇒ [tex]0.26[/tex]

Hence we can conclude that the relative frequency of landing on an egg, caterpillar, chrysalis, and adults are 0.2, 0.24, 0.3 and 0.26.

Answer:

Step-by-step explanation:

PX is 15 which is the radius

Find the circumference of the circle and subtract the length of the minor arc

Circumference of circle = 2 * pi * r = 2 * pi * 15 = 30 pi

length of arc = angle/360 * 2 * pi * r = 23/360 * 2 * pi * 15 = 1.92 pi

subtraction will give 30 pi - 1.92 pi = 28.08 pi

28.08 * 22/7 = 88.25 which is approximately 88

Answer:

[tex]f(x)=-5x-3[/tex].

Step-by-step explanation:

From the given machine diagram it is clear that:

[tex]f(x)=-8[/tex] at [tex]x=1[/tex]

[tex]f(x)=-13[/tex] at [tex]x=2[/tex]

[tex]f(x)=-18[/tex] at [tex]x=3[/tex]

It is clear that the value of f(x) decreasing by 5 when the value of x is increasing by 1.

Since the function changing at a constant rate, therefore it represents a linear function.

If a linear function passing through two points, then the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

The given linear function passes through (1,-8) and (2,-13), therefore the linear equation is

[tex]y-(-8)=\dfrac{-13-(-8)}{2-1}(x-1)[/tex]

[tex]y+8=\dfrac{-5}{1}(x-1)[/tex]

[tex]y+8=-5(x-1)[/tex]

[tex]y=-5x+5-8[/tex]

[tex]y=-5x-3[/tex]

So, the required function is [tex]f(x)=-5x-3[/tex].

Each quart contains 4 cups of soup. So, one gallon of soup contains 16 cups of soup. Therefore, 1 1/2 gallons of soup contains 16+8 = 24 cups. Therefore, the chef can serve 1 1/2 gallons of soup as 24 one-cup servings.

Answer:

[see below]

Step-by-step explanation:

Add all values together:

[tex]4+6+5+4+4+5+4+8 = 40[/tex]

There are 8 numbers in the data set.

40 ÷ 8 = 5

The mean of the data is 5.

Order the numbers in ascending order.

4, 4, 4, 4, 5, 5, 6, 8

There is no exact middle number.

[tex](4+5)/2 =4.5[/tex]

The median of the data is 4.5.

'4' appears the most in the data set.

4, 4, 4, 4, 5, 5, 6, 8

The mode of the data is 4.

Step-by-step explanation:

Each point moves to half its previous distance from P. It is probably easier to count grid squares on the graph than it is to do the math on the coordinates.

If you're doing the math on the coordinates, it is convenient to use P = (0, 0), then multiply each of the coordinates of A, B, and C by 1/2. For example:

  A' = (1/2)A = (1/2)(8, 4) = (4, 2)

Answer:

An exponential function is written in the form of f(x) = a (b)x. When we want to find an initial value of 500, it means that when x = 0, then y must equal 500. So, you plug in 0 to x in the exponential function, which leaves you with f(0) = a. Then, since f(0) = 500, that means a = 500

Answer:

They earn $256 on the ninth day of school.

Step-by-step explanation:

A geometric sequence(in which each term is the previous term multiplied by the ratio) has the following format:

[tex]a_{n+1} = r \times a_{n}[/tex]

In which r is the common ratio.

We can also find the nth term as a function of the first term, by the following equation:

[tex]a_{n} = a_{1} \times r^{n}[/tex]

In which

[tex]r = \frac{a_{n+1}}{a_{n}}[/tex]

In this question:

On the first day, $0.50. So [tex]a_{1} = 0.5[/tex].

Day two $1.00, day three $2.00.

So

[tex]r = \frac{1}{0.5} = \frac{2}{1} = 2[/tex]

Then

[tex]a_{n} = 0.5 \times 2^{n}[/tex]

How much do students earn on the ninth day of school?

[tex]a_{9} = 0.5 \times 2^{9} = 256[/tex]

They earn $256 on the ninth day of school.

Answer:

  B. ​False, because the description applies to a single solution. The solution set consists of all possible solutions.

Step-by-step explanation:

The choice of true or false revolves around whether a linear system can have more than one solution.

The problem statement does not say the equations are independent, a condition that must be satisfied if there is to be only one solution. Hence we must assume that the system may be dependent or even inconsistent, leading to zero, one, or an infinite number of solutions. The answer above carries its own explanation.

(2.5 x 10^9) + (5.3 x 10^8) =

(2.5 + 5.3) x (10^9 x 10^8) =

7.8 x 10^7=

7.8 x 10,000,000=

780,000,000

Bold is edited by me

Correct:

(2.5 x 10^9) + (5.3 x 10^8)=

(2.5 x 1,000,000,000)+(5.3 x 100,000,000)=

2,500,000,000+5,300,000,000=

7,800,000,000

The problem is that whoever wrote it swapped the numbers in the parentheses, added a pair of them together and multiplied the other pair. You are not supposed to take out the pairs and swap them if you'd like or the answer is incorrect. Second mistake is that [tex]10^{9} * 10^{8}[/tex] is not [tex]10^{7}[/tex] I do not know how and where you got that answer from.
