As given by the question

There are given that 4<6, so 204<216.

Now,

On the number line, 4 is less tha6 and 204 is also less than 216

Hence, the given reasoning is correct.

We have the following:

We can calculate the value x by means of the Pythagorean theorem that says the following

In this case the value of the hypotenuse is x, we replace and we have

The value of x is 13.85

Quantity 1

30

Unit 1

miles

Quantity 2

2.5

Unit 2

hours

= ?

Answer:

= 12 miles per hour

Showing Work

This is a fraction equal to

30 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

30 miles ÷ 2.5

2.5 hours ÷ 2.5

=

12 miles

1 hour

=

12 miles

hour

= 12 miles per hour

Let:

P = Profit

n = Number of increments by $1

R = Revenue

The profit is given by:

Therefore, the revenue is:

Expand the equation using the distributive property:

The maximum profit of this quadratic function is located at the vertex, we can find the vertex as follows:

The vertex is (0,10000) in another words the maximum profit is achieve if you don't raise the price.

The mixed fraction form

is equivalent to

since 5/6 is equal to 0.8333, then

Therefore, since 5.83333 is greater than 5.6, then 5 5/6 is greater than 5.6

10% commission means that Steve earns 10% of his sales. If he sells $5,680 worth of appliances this week, then he earns 10% of it, which is computed as follows:

Given that he has a base of $1,500, then he will earn $1,500 + $568 = $2068

Okay, here we have this:

Considering the provided quadratic function, we are going to rewrite in standard form, so we obtain the following:

So to rewrite the function in standard form we will complete the square:

And from this equation we get that the vertex is (4, -16)

Therefore the correct graph is the one in the upper right corner.

The dimensions of the enlargement will be: 32 inches by 28.8 inches.

The new dimensions can be gotten with the formula below:

Scale factor = Dimensions of new image / Dimensions of the original image.

Dimensions of new image = Scale factor × Dimensions of the original image

8 × 4 = 32 inches

8 × 3.6 = 28.8 inches.

Therefore, the new dimensions of the enlargement will be:

3 inches by 28.3 inches.

Answer:

  7.5 parts yellow

Step-by-step explanation:

The color moss green has violet and yellow paint mixed in the proportion 2 to 3. You want to know the number of parts of yellow paint that should be mixed with 5 parts of violet paint.

The proportion can be written different ways. We like to put the unknown value in the numerator. (x is the number of parts of yellow paint)

  yellow : violet = 3 : 2 = x : 5

Expressed as fractions, the proportion is ...

  [tex]\dfrac{3}{2}=\dfrac{x}{5}\\\\5\times\dfrac{3}{2}=x\qquad\text{multiply by 5}\\\\\dfrac{15}{2}=x=7.5\qquad\text{simplify}[/tex]

7.5 parts yellow paint should be mixed with 5 parts violet paint.

Additional comment

If you kept the proportion as violet : yellow, then the unknown value would be in the denominator. The solution to that proportion requires another step. Here, we just needed to multiply by the denominator value to find the unknown.

Given:

The inequalities are,

To find:

The correct graphs.

Explanation:

Let us find the intercepts.

For the first inequality,

When x = 0, we get,

When y = 0, we get

So, the intercepts are

For the second inequality,

When x = 0, we get,

When y = 0, we get

So, the intercepts are

So, the graph becomes,

The function y= √(x+11) + 5 has Domain x≥-11 .

The Domain of the function is defined as the set of all possible values , that can be input in the function .

In the question;

it is given that

Option(a)

the function is ,

y = √(x + 11) + 5

the square root is defined only for x≥0,

So, we have x+11≥0

subtracting 11 from both the side , we get

x ≥ -11

hence Domain is x≥-11 .

Option(b)

the function is ,

y = √(x - 11) + 5

we have x-11≥0

Adding 11 to both the side , we get

x ≥ 11

hence Domain is x ≥ 11 .

Option(c)

the function is ,

y = √(x + 5) - 11

we have x+5≥0

subtracting 5 from both the side , we get

x ≥ -15

hence Domain is x ≥ -5 .

Option(d)

the function is ,

y = √(x + 5) + 11

we have x+5≥0

subtracting 5 from both the side , we get

x ≥ -15

hence Domain is x ≥ -5 .

From above we can see that only option(a) has Domain as x ≥ -11.

Therefore , the function y= √(x+11) + 5 has Domain x≥-11 , option(a) is correct .

The given question is incomplete , the complete question is

Which function has the domain x ≥ -11?

(a) y = √(x + 11) + 5

(b) y = √(x - 11) + 5

(c) y = √(x + 5) - 11

We know that:

- s varies inversely as t

- s = 8 when t = 5

And we must find the equation that connects s and t

To find the equation that connects s and t we must use that

In this case, we can say that s = x and t = y. So, our equations would be

Now, knowing that s = 8 when t = 5 we can replace the values in the first equation

So, k = 40

Finally, replacing k = 40 in the second equation we obtain

ANSWER:

A) s = 40 / t

Triangles that have two sides at least equally spaced apart are said to be isosceles. As three-sided enclosed polygons with three sides, triangles are known to exist. Depending on the length of their sides, triangles can be categorized as equilateral, isosceles, or scalene.

The three interior angles of a triangle will always have a sum of 180°. A triangle cannot have an individual angle measure of 180°, because then the other two angles would not exist (180°+0°+0°).

So ,

x +x+38 = 180

2x = 180 -38

2x = 142

Answer:

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

Step-by-step explanation:

The correct relationship between the hikers distance and time is;

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

A group of hikers tracked how long it took to hike a 20-mile trail.

And, They hiked 3.75 miles in 3 hours, 7.5 miles in 6 hours, and 12 miles in 8 hours.

Now,

Find the proportional as;

For hiked 3.75 miles in 3 hours,

Proportional = 3.75 / 3

                   = 1.25

For hiked 7.5 miles in 6 hours,

Proportional = 7.5 / 6

                   = 1.25

For hiked 12 miles in 8 hours,

Proportional = 12 / 8

                   = 1.5

Thus, The correct relationship between the hikers distance and time is;

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

In order to find the length of the side CD in the pentagon ABCDE we would need to find the distance between the two points (4,-2) and (8, 2)

We would use the following formula:

plug in x1= 4, x2= 8, y1=-2, y2=2

So,

d=5,65

The length of the side CD in the pentagon ABCDE would be 5,62

On a number line, the coordinate of point A is negative and the coordinate of point B is positive.

The mid point is defined as:

a. When will the midpoint of line AB be positive?

When B>A

b. when will the midpoint of line AB be negative?

When A>B

c. when will the midpoint of line AB be zero?

When:

d. when will the distance from A to B be negative?

Never the distance is not defined as negative by definition of distance.

The distance is a magnitude and for this reason not makes sense say negative distance because is always 0 or positive, if for example we find the distance from A to A is 0 since we are in the same point, but we never say we travel -200 m to reach a city for example.
