Find the length of the midsegment.

Answer:

$0.45

Step-by-step explanation:

Unit price is basically the same as unit rate. Unit rate is the cost of one item.

So $3.15 divided by seven is point fourty-five.

Answer: 45 cents

Step-by-step explanation: Unit price means the cost per unit. In this case, the cost per notepad.

Since we know that it costs $3.15 for 7 notepads, to find the cost for 1 notepad, we need to divide 7 into $3.15 or 7 into 3.15.

I used long division wish I have shown in the image attached and ended up with .45 which means that each notepad costs 45 cents.

So the unit price for 7 notepads is 45 cents.

The slope of the line is: 1

The y-intercept is: -3

You can graph the line using the slope and y-intercept, or two points.

Answer:

1.

Step-by-step explanation:

The general form of a line is y = mx + c   where m = the slope.

y = x - 3

or we can write it as y = 1x - 3

- so the slope is 1.

Answer:

h = -3

The value h = -3 translates the graph of the parent function [tex]y=x^2[/tex] 3 units to the left.

Step-by-step explanation:

The graph of [tex]f(x)=(x-h)^2+k[/tex] contains the points (-6, -2) and (0, -2).

This is the equation of parabola in vertex form, where [tex](h,k)[/tex] are the coordinates of the vertex.

If the graph has a vertex at [tex](h,-5),[/tex] then [tex]k=-5.[/tex]

So, the equation of the parabola is

[tex]f(x)=(x-h)^2-5[/tex]

If the graph passes through the points (0,-2) and (-6,-2) (these two points lie on the same horizontal line y = -2), then the parabola vertical line of symmetry divides the segment between these points into two congruent segments. Hence, the equation of the line of symmetry is

[tex]x=\dfrac{0+(-6)}{2}=-3[/tex]

The vertex lies on the line of symmetry, so its x-coordinate is -3. Thus, (-3,-5) is the vertex.

The value h = -3 translates the graph of the parent function [tex]y=x^2[/tex] 3 units to the left.

Answer:

Sample Response: The absolute value function is symmetric. Since the points (–6, –2) and (0, –2) have the same output, the points are the same distance from the line of symmetry. Between –6 and 0 is the value of –3. So, the vertex must have an x-coordinate of –3, which is the value of h. This would translate the graph of the parent function 3 units to the left.

Answer: m = -2

Step-by-step explanation: Using our slope formula, we take the second y minus the first y which in this case is 12 - 8 over our second x minus our first x which in this case is 2 - 4.

So 12 - 8 is 4 and 2 - 4 is -2. So we have 4/-2 which can be simplified to -2.

The variable that's used to represent slope is m.

So we would say m = -2.

-3x+6y=12

X-intercept: 12/-3= -4

Y-intercept: 12/6=2

Answer:

Step-by-step explanation:

if ur gonna graph it, u should put it in y = mx + b form

-3x + 6y = 12

6y = 3x + 12

y = 3/6x + 12/6

y = 1/2x + 2

in y = mx + b form, the slope is in the m position, and the y int is in the b position.

y = mx + b

y = 1/2x + 2.....so ur slope (which will help u in graphing) is 1/2, and ur y intercept is 2 or (0,2) <===

u could also find ur y intercept by subbing in 0 for x and solving for y...in ur original equation.

to find ur x intercept, sub in 0 for y and solving for x

-3x + 6y = 12

-3x + 6(0) = 12

-3x = 12

x = -12/3

x = -4...so ur x int is -4 or (-4,0) <=====

Answer:

There are 71 students that are left

Step-by-step explanation:

Let's calculate the number of students left this way:

Total students = 30 * 6 = 180

Students that went to the the slides = 42

Students that went to the the swings = 28

Students that went to the the swings = 39

Students left = Total students - Students that went to the the slides - Students that went to the the swings - Students that went to the the swings

Replacing with the real values, we have:

Students left = 180 - 42 - 28 - 39

Students left = 180 - 109

Students left = 71

The number of kids attending the circus is 1300.

Let's denote:

- ( K ) as the number of kids attending the circus.

- ( A ) as the number of adults attending the circus.

Given:

- The price of a kid's ticket is $2.50.

- The price of an adult's ticket is $6.

- The total ticket sales is $7,150.

- The number of kids attending the circus is twice the number of adults.

We can set up a system of equations based on the given information:

1. The total ticket sales:

[tex]\[ 2.50K + 6A = 7150 \][/tex]

2. The number of kids attending the circus is twice the number of adults:

[tex]\[ K = 2A \][/tex]

Now, we can solve this system of equations.

We can substitute the expression for ( K ) from equation 2 into equation 1:

[tex]\[ 2.50(2A) + 6A = 7150 \][/tex]

[tex]\[ 5A + 6A = 7150 \][/tex]

[tex]\[ 11A = 7150 \][/tex]

Now, solve for ( A ):

[tex]\[ A = \frac{7150}{11} \][/tex]

[tex]\[ A \approx 650 \][/tex]

So, the number of adults attending the circus is approximately 650.

Now, we can find the number of kids attending the circus using the expression we found for ( A ) in terms of ( K ):

[tex]\[ K = 2A \][/tex]

[tex]\[ K = 2 \times 650 \][/tex]

[tex]\[ K = 1300 \][/tex]

So, the number of kids attending the circus is 1300.

Answer:

George fell asleep when he had traveled 1/5 of the total distance, slept 3/5 of the distance and he awoke up when he's still 1/5 away from his grandma

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

George fell asleep a fifth of the way

He awoke up when he still had to travel a quarter of the distance that he had traveled while sleeping

2. For what part of the journey had he been asleep?

George fell asleep a fifth of the way: 1/5 of the total distance traveled and 4/5 of the distance away from his grandma

When he awoke up = 1/4 * 4/5 = 1/5

He had been asleep = 5/5 - 1/5 -1/5 = 3/5

It means George fell asleep when he had traveled 1/5 of the total distance, slept 3/5 of the distance and he awoke up when he's still 1/5 away from his grandma

in y = mx + b form, the slope is in the m position and the y int is in the b position

y = -2x + 3.....slope is -2 and y int is 3

y = -2x - 1...slope is -2 and y int is - 1

same slope, different y int's....means parallel lines...NO SOLUTION

learn this...it helps

same slope, different y int's = no solution

different slopes, different y int's = 1 solution

same slope, same y int's = infinite solutions

Final answer:

The given system of equations represents two parallel lines with the same slope and different y-intercepts, implying there are no solutions where the lines intersect.

Explanation:

The system of equations provided is:

y = –2x + 3

y = –2x – 1

These two equations represent two separate lines. To determine the number of solutions to the system, we observe the slopes of the two lines. Both equations have the same slope of –2. Because they have the same slope but different y-intercepts, these two lines are parallel and will never intersect. Therefore, the system has no solutions.

What's the question?

Answer:

200 additional gallons of water are used when 40 people take a bath instead of a shower

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of water used when we take a bath = 20 gallons

Amount of water used when we take a shower = 15 gallons

Number of people who wants to take a bath = 40

2.  How much extra water is used?

Extra water is used = Number of people * (Amount of water used when we take a bath - Amount of water used when we take a shower)

Replacing with the real values, we have:

Extra water is used = 40 * (20 - 15)

Extra water is used = 40 * 5 = 200 gallons

Answer:

1/3

Step-by-step explanation:

We can solve using algebra: let x be the unknown number.

so 11/3 ÷ x = 11.

Solving:

11/3 = 11x.

x = 11/3 ÷11  = 1/3

You can also check the answer by going:

11/3 ÷ 1/3 = 11/3 x 3/1  = 33/3 = 11 (using fraction rules for multiplying and dividing ie. to divide by a fraction we multiple by it's reciprocal, and to multiply by a fraction, we multiple the numerators and the denominators).

11/3 divided by 1/3 so that it will be equals to 11.

When facing a division problem like 11/3 divided by what equals 11, we need to find a number which, when 11/3 is divided by it, gives us the result of 11. To solve this, let's set up an equation where the unknown number is represented by a variable, such as 'x':

11/3 ÷ x = 11

To find 'x', we need to isolate it. This can be done by multiplying both sides of the equation by 'x', and then dividing both sides by 11 to solve for 'x'.

(11/3) ÷ x = 11

(11/3) ÷ x × x = 11 × x

11/3 = 11x

Now we divide both sides by 11 to get:

x = (11/3) ÷ 11

x = 1/3

So, the fraction that you must divide 11/3 by to get 11 is 1/3.

Amanda learns 2.5 recipes per week, so over 6 weeks of training, she would be expected to learn 15 appetizer recipes.

To establish the rate of Amanda learning new appetizer recipes, we need to determine the relationship between time (in weeks) and the number of recipes she learned. After 2 weeks of training, she learned 5 recipes, so we can assume that she learns at a rate of 5 recipes per 2 weeks, or 2.5 recipes per week.

Consequently, to estimate how many recipes she will learn after 6 weeks, we multiply the rate by the amount of weeks, which is: 2.5 recipes per week * 6 weeks = 15 recipes. Therefore, Amanda would be expected to learn 15 appetizer recipes after 6 weeks of training.

Events A and B are not independent because [tex]P(A / B) \neq P(A)[/tex]

Step-by-step explanation:

Given that [tex]P(A)=0.25[/tex], [tex]P(B)=0.3[/tex] and [tex]P(A \text { and } B)=0.05[/tex]

Two events are said to be independent events, if it satisfies any one of the following conditions,

[tex]P(A / B) = P(A)[/tex] or [tex]P(B / A) = P(B)[/tex] or [tex]P(AB)=P(A)P(B)[/tex]

First, let us substitute the values in the equation [tex]P(A / B) = P(A)[/tex]

The formula to find [tex]P(A / B)[/tex] is [tex]P(A / B)=\frac{P(A \cap B)}{P(B)}[/tex]

Substituting the values, we get,

[tex]P(A / B)=\frac{0.05}{0.3} =0.1667[/tex]

But [tex]P(A)=0.25[/tex]

Hence, [tex]P(A / B) \neq P(A)[/tex]
