Answer:

2 scrapbook pages

I found the answer online

Aylin can create a maximum of 19 scrapbook pages by dividing the total number of items by the number of items on each page.

Aylin wants to set up all the pages of her scrapbook in the same way, with a combination of photos and newspaper clippings on every page.

She wants to make sure that no items are left over.

To find the greatest number of scrapbook pages Aylin can create, we need to divide the total number of items -

= 18 photos + 20 newspaper clippings

= 38 items

Now,

Since she wants each page to have the same combination, we can find the greatest common divisor (GCD) of 18 and 20, which is 2.

Therefore, Aylin can create a maximum of 38/2 = 19 scrapbook pages.

Answer:

Average Speed to complete the journey = 80 km/h

Step-by-step explanation:

Given,

The distance between Sydney and Goulburn = 200 kilometer.

Time to complete the journey = 2 hour 30 minutes

Converting the time into minutes -

2 hour 30 minutes

= (2 x 60) minutes + 30 minutes

= 120 minutes + 30 minutes

= 150 minutes

We know, to determine average speed, we have to divide the distance by time.

Therefore, Speed = [tex]\frac{Distance}{Time}[/tex]

Speed = [tex]\frac{200 km}{150 minutes}[/tex]

Speed = 1.33 km/minutes

Speed = (1.33 km x 60) km/hour (To convert it to hour, we have to multiply by 60)

Average Speed per hour = 80 km/h

The trampoline will attract a sales tax of $12 which will take its total price to $312.

The trampoline costs $300 without taxes being accounted for yet.

The tax is 4%. In dollar terms this is:

= Sales tax percentage x Cost of trampoline

= 4% x 300

= $12

The total price of the trampoline will therefore be:

= Cost of trampoline + sales tax

= 300 + 12

= $312

In conclusion, the sales tax would be $12 and the total price would be $312.

-10<-6

Pair: (1,-10)

Answer:

Step-by-step explanation:

If we graph this system of inequalities, we could find the solution.

From the graph you can deduct that the only right answer is the last one (1,-10), because the area of solution is only for negative values of y.

Therefore, the right choice is the last one.

If you can't graph, you can try another method. If we replace the value in the system, it should satisfy it, that is, it should gives us a true result like 0<1 for example. Let's try

For x=1 and y=-10, we have

-10 ≤ 1 − 5

-10 ≤ −1 − 4

-10 ≤ -4

-10 ≤ -5

As you can see, the result is true, because -10 is less than -4 and -5, so that's the right answer.

Answer:

( - 1, 1 )

Step-by-step explanation:

Given the 2 equations

3x - y = - 4 → (1)

x + y = 0 → (2)

Subtract y from both sides in (2)

x = - y → (3)

Substitute x = - y into (1)

- 3y - y = - 4, that is

- 4y = - 4 ( divide both sides by - 4 )

y = 1

Substitute y = 1 into (3)

x = - 1

Solution is (- 1, 1 )

The solution to the system of equations 3x - y = -4 and x + y = 0 is found by substitution, resulting in the solution set (x, y) = (-1, 1).

To find the solution to the equations 3x - y = -4 and x + y = 0, you can use the method of substitution or elimination. Since the second equation easily gives us y in terms of x (that is, y = -x), we can substitute this into the first equation.

Substitute y = -x into the first equation: 3x - (-x) = -4.

Simplify: 3x + x = 4x

hence, 4x = -4

Divide both sides by 4 to solve for x: x = -1.

Now substitute x = -1 into y = -x to find y: y = -(-1) = 1.

The solution to the system of equations is (x, y) = (-1, 1).

Step-by-step explanation:

1.-92%

2.40%

3.-76%

4.65%

The percent changes for each scenario is: 1. From 1000 to 80: -92% 2. From 45 to 63: +40% 3. From 250 to 60: -76% 4. From 60 to 99: +65%.

To calculate the percent change between two values, we use the formula:

[tex]\[ \text{Percent Change} = \left( \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \right) \times 100\% \][/tex]

1. The percent change from 1000 to 80 is calculated as follows:

[tex]\[ \text{Percent Change} = \left( \frac{80 - 1000}{1000} \right) \times 100\% = \left( \frac{-920}{1000} \right) \times 100\% = -92\% \][/tex]

So, the percent change is a 92% decrease.

2. The percent change from 45 to 63 is calculated as follows:

[tex]\[ \text{Percent Change} = \left( \frac{63 - 45}{45} \right) \times 100\% = \left( \frac{18}{45} \right) \times 100\% = \frac{2}{5} \times 100\% = 40\% \][/tex]

So, the percent change is a 40% increase.

3. The percent change from 250 to 60 is calculated as follows:

[tex]\[ \text{Percent Change} = \left( \frac{60 - 250}{250} \right) \times 100\% = \left( \frac{-190}{250} \right) \times 100\% = -76\% \][/tex]

So, the percent change is a 76% decrease.

4. The percent change from 60 to 99 is calculated as follows:

[tex]\[ \text{Percent Change} = \left( \frac{99 - 60}{60} \right) \times 100\% = \left( \frac{39}{60} \right) \times 100\% = \frac{13}{20} \times 100\% = 65\% \][/tex]

So, the percent change is a 65% increase.

Answer:

Money spent on each student is $36.17

Step-by-step explanation:

$875.49 = 29 students & 4 teachers

33 people = $875.49

1 person = $26.53 (pass)

29 students = $279.56

1 student = $9.64 (lunch)

each student = $9.64 + $26.53

= $36.17

the amount spent on a pass and lunch for each student is approximately $26.56 + $9.63 = $36.19.

To find out how much money was spent on a pass and lunch for each student, we need to calculate the total amount spent on passes and lunch and then divide it by the total number of students.

Given:

- Total amount spent on passes for 29 students and 4 teachers: $875.49

- Total amount spent on lunch for just the students: $279.56

- Total number of students: 29

1. First, let's find the total amount spent on passes for just the students:

  Total amount spent on passes for students and teachers = $875.49

  Total amount spent on passes for 4 teachers = ?

  Total amount spent on passes for students = $875.49 - (amount spent on passes for teachers)

  Since each pass costs the same amount for students and teachers, we can divide the total amount spent on passes by the total number of passes (students + teachers) to find the cost per pass.

  Total number of passes (students + teachers) = 29 students + 4 teachers = 33 passes

  Cost per pass = Total amount spent on passes / Total number of passes

                = $875.49 / 33

                ≈ $26.56 (rounded to two decimal places)

2. Now, let's find out how much money was spent on lunch for each student:

  Total amount spent on lunch for students = $279.56

  Cost per student for lunch = Total amount spent on lunch for students / Total number of students

                              = $279.56 / 29

                              ≈ $9.63 (rounded to two decimal places)

So, the amount spent on a pass and lunch for each student is approximately $26.56 + $9.63 = $36.19.

Answer:

g(x) = |x+3| - 5

Step-by-step explanation:

Let y = f(x)

⇒y = |x+3|

When y is replaced by Y + k, the graph of y = f(x) shifts k units down

⇒ y replaced by Y + 5 translates the graph of y = f(x) 5 units down

∴ Y = g(x) is represented by Y + 5 = |x+3|

⇒ Y = |x+3| - 5

or g(x) = |x+3| - 5

For this case we have that by definition, the equation of a line in the standard form is given by:

[tex]ax + by = c[/tex]

According to the statement we have the following equation of the line:

[tex]y + 1 = \frac {2} {5} (x + 3)[/tex]

We manipulate algebraically to write in the standard form. To do this we follow the steps below:

We apply distributive property on the right side of the equation:[tex]y + 1 = \frac {2} {5} x + \frac {6} {5}[/tex]

We subtract [tex]\frac {6} {5}[/tex] on both sides of the equation:

[tex]y + 1- \frac {6} {5} = \frac {2} {5} x\\y- \frac {1} {5} = \frac {2} {5} x[/tex]

We multiply by 5 on both sides of the equation:

[tex]5y-1 = 2x[/tex]

We subtract 5y on both sides of the equation:

[tex]2x-5y = -1[/tex]

Finally, the equation in its standard form is:

[tex]2x-5y = -1[/tex]

Answer:

[tex]2x-5y = -1[/tex]

Answer:

2,300

Step-by-step explanation:

see attached to identify the hundreds digit.

How we round the hundreds digit depends on the number in the tens place.

If the number in the tens places is less than 5, then we keep the hundreds digit the same (i.e we round down)

If the number in the tens place is greater or equal to 5, then we increase the hundreds digit by 1 (i.e round up)

in this case, the digit in the tens place is 1 (i.e less than 5) hence we round down by keeping the hundreds place the same

we end up with 2,300

2,319 rounded to the nearest hundreds is 2,300.

To round the number 2,319 to the hundreds place, follow these steps:

Therefore, the answer is 2,300.

Find the measure of angle a

m∠a=m∠c ----> by vertical angles

so

m∠a=56°

step 4

Find the value of m∠ a + m∠b

m∠a=56°

m∠b=34°

m∠ a + m∠b=56°+34°

m∠ a + m∠b=90°

The equation for the total amount for the fair and rides is given by the relation y = 0.75n + 7  where n is the total number of rides

The amount left after purchasing 6 tokens is $ 3.50

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount be represented as = y

Now , the number of rides be = n

The cost of entry fee = $ 7

The cost for each ride = $ 0.75

The total amount available = $ 15

So , the equation will be

total amount = cost for each ride x number of rides + cost of entry fee

Substituting the values in the equation , we get

Total amount y = 0.75n + 7

y = 0.75n + 7

So , the equation is y = 0.75n + 7

Now , when purchasing 6 tokens , we get the remaining amount as

Substituting the value of n = 6 in the equation , we get

y = 0.75 x 6 + 7

y = 4.5 + 7

y = $ 11.5

So , the amount left = 15 - y

The total amount left = 15 - 11.5

The total amount left = $ 3.50

Hence , The equation for the total amount for the fair and rides is given by the relation y = 0.75n + 7  where n is the total number of rides

The amount left after purchasing 6 tokens is $ 3.50
