The roses that Leanna cut in her front yard is 28 roses.

From the information, she uses one quarter of her roses to make a bouquet of a dozen flowers. Therefore, the total flowers will be:

= 12 ÷ 1/4

= 12 × 4

= 48 flowers

Since she cuts some roses in her front garden and another 20 in her back garden, the number that she cut in the front garden will be:

= 48 - 20

= 28 flowers.

Value of (F/G)(-3)  with the given functions F(x)=x² -19 and G(x) = 14 - x is equal to (-10/17).

As given,

Given functions

F(x)=x² -19

G(x)=14 - x

Substitute the values in the required function:

( F/G )(x)=( x² -19 )/( 14 - x)

Now substitute x= -3

( F/G )( -3) =[ (-3)² -19 ] /[ 14 - (-3) ]

⇒ ( F/G )(-3) =( 9-19) / (14+ 3)

⇒ ( F/G )(-3) =( -10/17)

Therefore, value of (F/G)(-3)  with the given functions F(x) = x² -19 and G(x) = 14 - x is equal to (-10/17).

Step-by-step explanation:

By using the concept of internal angles of a triangle, the solution of the system of linear equations related to the geometrical system is (x, y) = (40, 40).

In this system we have a geometrical system formed by two right triangles with a common hypotenuse. Right triangles are triangles where one of its internal angles are right angles and the sum of the measures of the internal angles within a triangle equals 180°. Then, this geometrical system can be modelled by using the following linear equations:

(x + 20) + 90 + 30 = 180         (1)

20 + 90 + (y + 30) = 180         (2)

By using the concept of internal angles of a triangle, the solution of the system of linear equations related to the geometrical system is (x, y) = (40, 40).

The line AB joining the points A and B on the plane M lies in plane M.

Say there are two points A and B which lies on the plane M.  

Through any two points, there is only one line. Then there is exactly one line joining the two points A and B which is the line AB

Since both the points lies on the plane M, the line joining them should also lie on the plane M.

The postulate which verifies this is:

If two points lie on a plane, then the line joining the points also lies on the same plane.

Answer: i think its 1238 dollars

Step-by-step explanation:

We have the profit fomula:

P = R - C

= $10.x - ($3.x + 1000)

= $7.x - 1000

1. If the company sells 1000 pens:

P = $7 . 1000 - $1000

= $6000

2. If they want to break even:

P at least = 0

Assume P = 0

=> $7.x - $1000 = 0

=> x = 1000/7 ≈ 142,86

So if they want to break even, they have to sell at least 143 pens

Step-by-step explanation:

Using the average rate of change concept, we have that:

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For item 1, when the time in minutes changes by 1, the height changes by 9.5 units, hence the rate is given by:

r = 9.5/1 = 9.5 feet per minute.

For item 2, we want a table with a rate of -3, hence, when the first column changes by 1, the second column should always change by -3, hence the table is:

A 2-column table with 4 rows. Column 1 is labeled x with entries negative 22, negative 21, negative 20, negative 19. Column 2 is labeled y with entries 2, negative 1, negative 4, negative 7.

Answer:

The tip was 20.6% or 20.59% of the original bill

Step-by-step explanation:

Question: The bill for dinner was $77.12. You left $15.88 for the tip. What percentage of the original bill was the tip?

Step-by-step:

To find the percentage of how much a part ($15.88) is or a whole ($77.12), the formula of part = percentage * whole is used.

It is usually written as a = p*w

In this case, $15.88 is a and $77.12 is w.

so, 15.88 = p*77.12

However, we need to find p. To do so, we need to get p by itself. Divide 77.12 on both sides so that it cancels out on the right side.

15.88 divided by 77.12 is about 0.2059

We need to make the decimal a percentage by multiplying 100

0.2059 * 100 = 20.59%

You could probably round it up to 20.6% if you wanted to

Therefore, the tip was 20.6% or 20.59% of the original bill.

The scale factor is 4/3

Step-by-step explanation:

Let x = the scale factor

15x = 20  Divide both sides by 15

x =20/15  Which simplifies to 4/3

The scale factor that was used to create WH will be 4/3.

The scale factor is defined as the proportion of the new image's size to that of the previous image decision-making. Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.

Given that BF is dilated to create WH. The center of dilation is point A where BF=15, WH=20

The scale factor will be calculated as below:-

Let x = the scale factor

15x = 20  

Divide both sides by 15

x =20/15  

Which simplifies to 4/3.

x = 4 / 3

Therefore, the scale factor that was used to create WH will be 4/3.

There are 56 milligrams in 8 milliliters of the drug if the drug's label says each milliliter contains 7 milligrams of the substance.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Let x milligrams would in 8 ​milliliters.

We can write this as a ratio as

As per the given information,

1 milliliter  : 7 milligrams  = 8 milliliter   : x milligrams

⇒ 1 / 7 = 8 / x

⇒ x = 8 × 7

⇒ x = 56 milligrams

Hence, there are 56 milligrams in 8 ​milliliters of the drug.

A statement, rule, or regulation that establishes the relationship between an independent variable and a dependent variable is known as a function.

A network can be represented mathematically as a graph, which explains the connection between lines and points. A graph consists of some points with connecting lines.

Consider the function,

[tex]f(x)=\frac{||x||+2}{2}[/tex] and 0 ≤ x ≤ 6

To graph the function we will find the points on the graph for different values of x.

When x = 0,

[tex]f(x)=\frac{||x||+2}{2}[/tex]

[tex]f(x)=\frac{||0||+2}{2}=1[/tex]

When x = 1,

[tex]f(x)=\frac{||x||+2}{2}[/tex]

[tex]f(1)=\frac{||1||+2}{2}\\ f(1)=\frac{3}{2}[/tex]

When x = 2,

[tex]f(x)=\frac{||x||+2}{2}[/tex]

[tex]f(2)=\frac{||2||+2}{2}[/tex]

[tex]f(2)=2[/tex]

When x = 3,

[tex]f(x)=\frac{||x||+2}{2}[/tex]

[tex]f(3)=\frac{||3||+2}{2}[/tex]

[tex]f(3)=\frac{5}{2}[/tex]

When x = 4,

[tex]f(x)=\frac{||x||+2}{2}[/tex]

[tex]f(4)=\frac{||4||+2}{2}\\ f(4)=3[/tex]

When x = 5,

[tex]f(x)=\frac{||x||+2}{2}[/tex]

[tex]f(5)=\frac{||5||+2}{2}[/tex]

[tex]f(5)=\frac{7}{2}[/tex]

When x = 6,

[tex]f(x)=\frac{||x||+2}{2}[/tex]

[tex]f(6)=\frac{||6||+2}{2} \\f(6)=4[/tex]

Therefore, the points on the graph of the function [tex]f(x)=\frac{||x||+2}{2}[/tex] are ( 0, 1 ), ( 1, ( 3/2 ) ), ( 2, 2 ), ( 2, ( 5/2 ) ), ( 4, 3 ), ( 5, ( 7/2 ) ), and ( 6, 4).
