Answer:

length of shortest piece = 13 in

length of middle piece =  19 in

length of longest piece =  22 in

Step-by-step explanation:

Total length of sandwich = 54 inch

Let shortest piece = x

Middle piece = x+6

Longest piece = x+9

Add this pieces will make complete sandwich

x+(x+6)+(x+9) = 54

Solving

x+x+6+x+9 = 54

Combining like terms

x+x+x+6+9 = 54

3x + 15 = 54

3x = 54 -15

3x = 39

x = 13

So, length of shortest piece = x = 13 in

length of middle piece = x+6 = 13+6 = 19 in

length of longest piece = x+9 = 13+9 = 22 in

Answer:

The three pieces should be 13 , 19 , 22 inches

Step-by-step explanation:

* Lets study the information to solve the problem

- The length of the sandwich is 54 in

- The sandwich will cut into three pieces

- The middle piece is 6 inches longer than the shortest piece

- The shortest piece is 9 inches shorter than the longest piece

* Lets change the above statements to equations

∵ The shortest piece is common in the two statements

∴ Let the length of the shortest piece is x ⇒ (1)

∵ The middle piece is 6 inches longer than the shortest piece

∴ The length of the middle piece = x + 6 ⇒ (2)

∵ The shortest piece is 9 inches shorter than the longest piece

∴ The longest piece is 9 inches longer than the shortest piece

∴ The longest piece = x + 9 ⇒ (3)

∵ the length of the three pieces = 54 inches

- Add the length of the three pieces and equate them by 54

∴ Add (1) , (2) , (3)

∴ x + (x + 6) + (x + 9) = 54 ⇒ add the like terms

∴ 3x + 15 = 54 ⇒ subtract 15 from both sides

∴ 3x = 39 ⇒ divide both sides by 3

∴ x = 13

* The length of the shortest piece is 13 inches

∵ The length of the middle piece = x + 6

∴ The length of the middle piece = 13 + 6 = 19 inches

* The length of the middle piece is 19 inches

∵ The length of the longest piece = x + 9

∴ The length of the longest piece = 13 + 9 = 22 inches

* The length of the longest piece is 22 inches

* The lengths of the three pieces are 13 , 19 , 22 inches

Answer:

c

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( where m is the slope and c the y- intercept )

Given y = 2x - 3 ← in slope- intercept form

with m = 2

• Parallel lines have equal slopes, hence

y = 2x + c ← is the partial equation of the parallel line

To find c substitute (- 1, 2) into the partial equation

2 = - 2 + c ⇒ c = 2 + 2 = 4

y = 2x + 4 → c

Answer:

42 degrees

Step-by-step explanation:

So we are given that m<BOC+m<AOB=90

So we have (6x-6)+(5x+8)=90

11x+2=90

11x=88

x=8

We are asked to find m<BOC

m<BOC=6x-6=6(8)-6=48-6=42

Final answer:

To convert 720° to radians, multiply by π/180 to get 4π rad. This shows that 720° is equivalent to 4π radians.

Explanation:

To convert 720° to radians, we use the relationship that 1 revolution equals 360° or 2π radians. Therefore, to convert degrees to radians, you multiply the number of degrees by π/180. In this case:

720° × (π rad / 180°) = 4π rad

Thus, 720° is equal to 4π radians. The concept of angular velocity is related to radians as it is the rate of change of an angle with time, and using radians can be especially useful in calculations involving angular motion.

Answer:

F(4) = G(4) and F(12) = G(12) ⇒ answer B

Step-by-step explanation:

* Lets explain the meaning of the common solutions of two equation

- If two equations intersect at one point, (x , y) where x and y have the

 same values for both equations

- The point (x , y) belongs to the two graphs

- Ex: If (2 , 3) is a common solution of f(x) and g(x) , then the graphs of

 f(x) and g(x) meet each other at the point (2 , 3) that means f(2) = 3

 and g(2) = 3

- So f(2) = g(2)

* Lets solve the problem

∵ F(x) = Ix - 6I

∵ G(x) = 0.5 x

∵ The two graphs intersected at points (4 , 2) and (12 , 6)

- That means the two points (4 , 2) and (2 , 6) on the two graphs

∴ F(4) = 2 and G(4) = 2

∴ F(12) = 6 and G(12) = 6

- That means the two points are common solutions for both equations

∴ The solutions of the equation |x - 6|= 0.5 x are x = 4 and x = 12

∴ F(4) = G(4) and F(12) = G(12)

∴ The  best reasons which justifies Kiana's conclusion is;

   F(4) = G(4) and F(12) = G(12)

- Look to the attached graph to more understanding

- The red graph is F(x)

- The blue graph is G(x)

The best justification of Kiana's conclusion is ; F(4) = G(4) and F(12) = G(12) Option B

The justification for Kiana's conclusion is that the values of x and y at the points of intersection are the same for both equations.

This means that the point (x, y) belongs to both graphs.

For example, if (2, 3) is a common solution of f(x) and g(x), then the graphs of f(x) and g(x) intersect at the point (2, 3), which implies that f(2) = 3 and g(2) = 3. Therefore, f(2) = g(2).

To solve the problem at hand, we have

F(x) = |x - 6| and G(x)

= 0.5x.

Given that the two graphs intersect at the points (4, 2) and (12, 6),

Consequently, F(4) = 2 and G(4) = 2, as well as

F(12) = 6 and

G(12) = 6.

These common solutions indicate that the solutions of the equation

|x - 6| = 0.5x are

x = 4 and x = 12.

Answer:16.66

Step-by-step explanation:

To convert 1/6 into a percent, multiply by 100 to get approximately 16.67 percent.

To convert a fraction to a percent, you can follow a standard way of expressing the fraction such that the denominator equals 100. For 1/6, you want to find what number over 100 is equivalent to it. To do so, you can set up a proportion where 1/6 equals x/100. Solving for x, you would cross-multiply and divide to get:

1 * 100 = 6 * x
[tex]\( x = \frac{100}{6} \)[/tex]
x ≈ 16.67

The probability [tex]\( P(A \cap B \cap C) \)[/tex] from the Venn diagram is [tex]\( \frac{2}{25} \)[/tex], as 4 out of 50 elements overlap.

To find [tex]\( P(A \cap B \cap C) \)[/tex] from the given Venn diagram, we need to identify the part of the diagram where all three sets A, B, and C overlap, and then calculate the probability of landing in that part of the diagram.

The numbers within each section of the Venn diagram represent the number of elements in that section. The overlapping section of A, B, and C is the center where all three circles intersect, which has the number 4 in it. This means there are 4 elements that are in all three sets A, B, and C.

The correct expansion of  (3x + 2)(3x² + 4) will be 9x³ + 12x + 6x² +8.

In order to expand any factor, we need to multiply the first term with all two-term with another bracket.

Final answer:

The correct expansion of the expression (3x + 2)(3x² + 4) is found by multiplying each term of the first binomial by each term of the second polynomial, resulting in the expanded form 9x³ + 12x + 6x² + 8.

Explanation:

The student's question refers to the process of expanding a binomial multiplied by a polynomial using the distributive property (also known as the FOIL method for binomials). To expand it, each term in the first binomial is multiplied by each term in the second polynomial and the results are then added together. Applying this method:

Adding all these products together gives the expanded form: 9x³ + 12x + 6x² + 8. It is important to also combine like terms if there are any; however, in this expansion, there are no like terms to combine.

Answer:

x = 6

Step-by-step explanation:

First, write the proportion, using a letter to stand for the missing term. We find the cross products by multiplying 8 times x, and 2 times 24. Then divide to find x. Study this step closely, because this is a technique we will use often in algebra. We are trying to get our unknown number, x, on the left side of the equation, all by itself. Since x is multiplied by 8, we can use the "inverse" of multiplying, which is dividing, to get rid of the 8. We can divide both sides of the equation by the same number, without changing the meaning of the equation. When we divide both sides by 8, we find that the x would equal 6.

The answer is:

The ordered pair satisfies the following system of equations since it satisfies both equations.

If we need to know if the ordered pair (-11/3,2/3) satisfies the system of equations we need to evaluate it and check if it satisfies both equations, we must remember that the condition that determines if the system of equations is satisfied is that both equations must be satisfied.

So, evaluating the ordered pair, we have:

First equation:

[tex]-x+5y=7\\\\-(\frac{-11}{3})+5*\frac{2}{3}=7\\\\\frac{11}{3}+\frac{10}{3}=7\\\\\frac{11+10}{3}=7\\\\\frac{21}{3}=7\\\\7=7[/tex]

We have that the equation is satisfied.

Second equation:

[tex]-x-7y=-1\\\\-(\frac{-11}{3})-7*\frac{2}{3}=-1\\\\\frac{11}{3}-\frac{14}{3}=-1\\\\\frac{11-14}{3}=7\\\\\frac{-3}{3}=-1\\\\-1=-1[/tex]

We have that the equation is satisfied.

Hence, we have that the ordered pair satisfies the system of equations since it satisfies both equations

Have a nice day!

Final answer:

The ordered pair (-11/3, 2/3) satisfies both equations in the given system, making it a solution to the system of equations.

Explanation:

To determine if the ordered pair (-11/3, 2/3) satisfies the given system of equations, we substitute x with -11/3 and y with 2/3 into both equations.

For the first equation -x + 5y = 7, we get:
-(-11/3) + 5(2/3) = 7
11/3 + 10/3 = 7
21/3 = 7
7 = 7
This confirms that the ordered pair satisfies the first equation.

For the second equation -x - 7y = -1, we calculate:
-(-11/3) - 7(2/3) = -1
11/3 - 14/3 = -1
-3/3 = -1
-1 = -1
The ordered pair also satisfies the second equation.

Since the ordered pair satisfies both equations, it is a solution to the system.

Answer:

g and h

Step-by-step explanation:

both g and h have constant relationships while f's f(x) values aren't constant so it doesn't have a linear relationship

Answer:

Of the three functions g and h represent linear relationship.

Step-by-step explanation:

If a function has constant rate of change for all points, then the function is called a linear function.

If a lines passes through two points, then the slope of the line is

[tex]m=\frac{x_2-x_1}{y_2-y_1}[/tex]

The slope of function f(x) on [1,2] is

[tex]m_1=\frac{11-5}{2-1}=6[/tex]

The slope of function f(x) on [2,3] is

[tex]m_2=\frac{29-11}{3-2}=18\neq m_1[/tex]

Since f(x) has different slopes on different intervals, therefore f(x) does not represents a linear relationship.

From the given table of g(x) it is clear that the value of g(x) is increased by 8 units for every 2 units. So, the function g(x) has constant rate of change, i.e.,

[tex]m=\frac{8}{2}=4[/tex]

From the given table of h(x) it is clear that the value of h(x) is increased by 6.8 units for every 2 units. So, the function h(x) has constant rate of change, i.e.,

[tex]m=\frac{6.8}{2}=3.4[/tex]

Since the function g and h have constant rate of change, therefore g and h represent linear relationship.

To order the relative frequencies from least to greatest, we need to determine the relative frequency for each data value. The relative frequency is found by dividing the frequency by the total number of data values. The cumulative relative frequency is the sum of all previous relative frequencies. Here are the calculations:

Relative Frequency:
114,950 : 0.00002
158,000 : 0.00003
230,500 : 0.00005
387,000 : 0.00008
389,950 : 0.00008
479,000 : 0.00010

659,000 : 0.00013
1,095,000 : 0.00022
5,500,000 : 0.00100

114,950 : 0.00002
158,000 : 0.00003
230,500 : 0.00005
