Answers: 16 states and [tex]\frac{16}{50}[/tex]

Explanation:

Question A involves finding the number of states that do not have a store operated by company A. This can be easily found by subtracting the number of states where the company operates stores, which is 34 states, from the total of states, which is 50.

50 - 34 = 16

This means 16 states do not have a store operated by this company

Question B involves writing a fraction to represent the number of states that do not have a store operated by the company. A fraction includes a numerator (top number) that represents the parts selected (number of states without a store: 16), and a denominator, which is the total of parts (total of states: 50). Thus, the fraction is [tex]\frac{16}{50}[/tex]. Moreover, this can be simplified as [tex]\frac{8}{25}[/tex] by dividing both numbers by the seame number (2).

Answer:

The highest point reached by the firework is approximately 30.6 meters

Step-by-step explanation:

The upward velocity of the fireworks is given as 24.5 m/s

The equation of projectile motion for an object fired vertically upwards can be written as follows;

v² = u² - 2·g·s

Where;

v = The final velocity of the motion = 0 m/s at maximum height

u = The final velocity of the motion =  24.5 m/s

g = Acceleration due to gravity = 9.81 m/s²

s = The height reached = (The highest point reached by the firework)

By substituting the values, we have;

(0 m/s)² = (24.5 m/s)² - 2 × 9.81 m/s² × s

Which gives;

2 × 9.81 m/s² × s = (24.5 m/s)² = 600.25 m²/s²

19.62 m/s² × s = 600.25 m²/s²

s = 600.25 m²/s²/(19.62 m/s²) = 30.594 m ≈ 30.6 meters

The highest point reached by the firework is approximately 30.6 meters

Answer:

20 represent the cost per variable inputs

Step-by-step explanation:

C(x) = 20(4x) + 500

Total cost is the addition of variable cost and fixed cost

Fixed cost are cost that do not change during the production process such as machinery, furnitures and fittings.

Variable cost are cost of production that changes with production process such as cost of labor, cost of raw materials.

C(x) = 20(4x) + 500

C(x) represent the total cost

20(4x) represent the variable cost

500 represent the fixed cost

From the variable cost 20(4x)

20 represent the cost per variable inputs

Answer:

The vector [tex]\vec v = (3,-2,3)[/tex] points from the origin to the point (3,-2,-3).

Step-by-step explanation:

Geometrically speaking, a vector is the change between a final point and a initial point. Since vector are located in space, the origin is represented by point (0, 0, 0) That is:

[tex]\vec v = (3,-2,3)-(0,0,0)[/tex]

[tex]\vec v = (3-0,-2-0,3-0)[/tex]

[tex]\vec v = (3,-2,3)[/tex]

The vector [tex]\vec v = (3,-2,3)[/tex] points from the origin to the point (3,-2,-3).

To solve the problem we must know about Vector points.

A point is a position in space. It is represented by a dot.

A vector is something that has both magnitude and direction but no fixed position in space. it is represented by an arrow pointing in a particular direction.

When we draw vectors, we attach them to specific points, but we should remember that the vector has no fixed position. These points are known as vector points.

The vector will point toward the point (3, -2, 3) in space.

As we know a vector has no fixed position in space, but it points towards its final condition starting from the initial condition. Therefore, its tail is towards the initial condition while its arrowhead is towards the final condition. Thus,

Final condition - Initial Condition

= (3, -2, 3) - (0, 0, 0)

= (3-0, -2-0, 3-0)

= (3, -2, 3)

Hence, the vector will point toward the point (3, -2, 3) in space.

They each have two chocolates so those numbers of chocolates are the same.

Not counting the tubs, Arthur has one bag of chocolates and 25 loose chocolates; Oliver has two bags and 7 loose. If they both have the same total number of chocolates, then the difference in the number of loose chocolates they have (25-7=18) must be the number of chocolates in a bag.

There is no information given, in the problem as you show it, that allows us to determine the number of chocolates in a tub.

Answers: chocolates in a bag: 18. chocolates in a tub: unknown.

Answer:57465

Step-by-step explanation:

Answer:

0< k < 2

Step-by-step explanation:

x = 2k

3x + 2y = 12

Substitute the first equation into the second equation

3(2k) +2y = 12

6k+2y = 12

Subtract 6k from each side

2y = 12 -6k

Divide by 2

y = 6 - 3k

For this to be in the first quadrant y > 0

6 - 3k > 0

6 > 3k

Divide by 3

2 > k

The lower limit is when it reaches the axis or when k=0

0 <k <2

Checking for x

x = 2k

If 0<k <2 then it will be in the first quadrant

Answer:

k = any value between 0 and 2

Step-by-step explanation:

We can start by considering the graph of 3x + 2y = 12. If you convert this line into point - slope form it will have a negative slope, and hence will extend infinitely in the negative direction. Therefore if we calculate the x - intercept, k will be bound by 0 to the x - intercept if their intersection lies in the first quadrant.

3x + 2y = 12,

3x + 2(0) = 12,

3x = 12,

x = 4 - this is the x - intercept

As x = 4 is the x - intercept, k can be any value between 0 and 4, and will lie in the first quadrant. But remember that we have the equation " x = 2k. " k will only be between 0 and 4 is the equation is " x = k. "

- Therefore k will instead be any positive value between 0 and 2.

Answer:

x=20

Step-by-step explanation:

Substitute 15 for y

it will be 2/3 multiplied by 15 then you get 10

you add 10 to 30 getting 40

then you divide 40 by 1/2 getting 20

:)))

Answer:

x = 80

Step-by-step explanation:

First, plug the 15 into the y.

[tex]1/2x - 2/3(15) = 30[/tex]

Use PEMDAS to solve the parentheses, 2/3 of 15 is 10.

[tex]1/2x - 10 = 30[/tex]

Add 10 to both sides of the equation.

[tex]1/2x = 40[/tex]

Divide each side by 1/2 (or multiply by it's reciprocal, which is 2)

That will get you your answer of x = 80

Step-by-step explanation:

The equivalent decimal have 1 places right after the decimal point, if

the denominator of the fraction is 10.

And, The equivalent decimal have 2 places right after the decimal point, if

the denominator of the fraction is 100.

Here,

We have to determine places after the decimal point does the equivalent decimal have,

The denominator of the fraction is 10 and the denominator of the fraction is 100.

What is Decimal representation?

A decimal number is a number where the integer part is separated from the fractional part with the help of a decimal point.

Now,

Let the number 2 in numerator,

Denominator = 10

Then, Fraction = 2/10 = 0.2

Hence, The equivalent decimal have 1 places right after the decimal point.

Let the number 3 in numerator,

Denominator = 100

Then, Fraction = 3/100 = 0.03

Hence, The equivalent decimal have 2 places right after the decimal point.

So, The equivalent decimal have 1 places right after the decimal point, if

the denominator of the fraction is 10.

And, The equivalent decimal have 2 places right after the decimal point, if

the denominator of the fraction is 100.
