- What is the percent of increase from 5,000 to 8.000?

Answer:

[tex]\$ 199[/tex]

Step-by-step explanation:

Given: Maria spent $2388 for natural gas, last year.

Maria chooses to use balance billing process to pay this year´s gas bill.

Balance billing is a billing practice, where provider bill you the difference between total cost and allowed amount. It can be paid partially or monthly. It generally in practice for medical billing as healthcare bill are generated for difference between total cost and amount which is paid through insurance.

Now, lets find out monthly bill paid by Maria.

We know there are 12 months in a year.

∴ Monthly payment= [tex]\frac{\$ 2388}{12} = \$ 199[/tex]

∴Maria will pay $199 monthly as her gas bill this year.

Maria's monthly payment for natural gas this year using balance billing will be $199.

Step 1

Balance billing is a method where a utility company estimates the annual energy usage and divides it into equal monthly payments. To find Maria's monthly payment for natural gas this year, we divide the total amount she spent last year by 12 months.

Total amount spent last year = $2,388

Step 2

Monthly payment this year = Total amount spent last year / 12 months

[tex]\[ \text{Monthly payment} = \frac{2388}{12} = 199 \][/tex]

Maria's monthly payment for natural gas this year, using balance billing, will be $199, calculated by dividing the total amount she spent last year by 12 months.

Circumference = 56.52 inches.

Problem 7:

Diameter = 32 ft.

Circumference = 100.48 ft.

Problem 8:

Diameter = 26 yards.

Circumference = 81.64 yards.

Problem 9:

Diameter = 12 cm.

Circumference = 37.68 cm.

Step-by-step explanation:

Problem 4:

Given:

Diameter GH = 22 cm

We need to find the radius EF and Circumference of the circle.

Now radius is given by half of the diameter

Also Circumference is given by π times diameter.

Radius EF = [tex]\frac{1}{2}\times Diameter = \frac{1}{2}\times 22 = 11 \ cm[/tex]

Circumference = [tex]\pi \times Diameter = 3.14 \times 22 = 69.08\ cm[/tex]

Hence Radius = 11 cm

Circumference = 69.08 cm.

Problem 5:

Given:

Diameter OP = 28 mm

We need to find the radius MN and Circumference of the circle.

Now radius is given by half of the diameter

Also Circumference is given by π times diameter.

Radius MN = [tex]\frac{1}{2}\times Diameter = \frac{1}{2}\times 28 = 14 \ mm[/tex]

Circumference = [tex]\pi \times Diameter = 3.14 \times 28 = 87.92\ mm[/tex]

Hence Radius = 14 mm

Circumference = 87.92 mm.

Problem 6:

Given:

Diameter EF = 18 inches

We need to find the radius CD and Circumference of the circle.

Now radius is given by half of the diameter

Also Circumference is given by π times diameter.

Circumference = [tex]\pi \times Diameter = 3.14 \times 18 = 56.52\ in[/tex]

Hence Radius = 9 inches.

Circumference = 56.52 inches.

Problem 7:

Given:

Radius GH = 16 ft

We need to find the Diameter CD and Circumference of the circle.

Now Diameter is given by twice the radius.

Also Circumference is given by π times diameter.

Diameter KJ = [tex]2 \times radius = 2 \times 16 = 32 \ ft[/tex]

Circumference = [tex]\pi \times Diameter = 3.14 \times 32 = 100.48\ ft[/tex]

Hence Diameter = 32 ft.

Circumference = 100.48 ft.

Problem 8:

Given:

Radius LM = 13 yards

We need to find the Diameter CD and Circumference of the circle.

Now Diameter is given by twice the radius.

Also Circumference is given by π times diameter.

Diameter NO = [tex]2 \times radius = 2 \times 13 = 26 \ yards[/tex]

Circumference = [tex]\pi \times Diameter = 3.14 \times 26 = 81.64\ yards[/tex]

Hence Diameter = 26 yards.

Circumference = 81.64 yards.

Problem 9:

Given:

Radius NO = 6 cm

We need to find the Diameter CD and Circumference of the circle.

Now Diameter is given by twice the radius.

Also Circumference is given by π times diameter.

Diameter PQ = [tex]2 \times radius = 2 \times 6 = 12 \ cm[/tex]

Circumference = [tex]\pi \times Diameter = 3.14 \times 12 = 37.68\ cm[/tex]

Circumference = 37.68 cm.

Answer:

7 without going over

Step-by-step explanation:

The number 7 can go into 50 a total of 7 times with 1 remainder.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

The number 7 can go into 50 a total of 7 times because 50 / 7 = 7 with 1 remainder.

To understand this, consider that when you divide 50 by 7, you are trying to find out how many groups of 7 can be created from 50. Since 50 is a multiple of 7 (50 is divisible by 7 with 1 remainder), there will be an integer number of groups. In this case, that integer is 7, so 7 groups of 7 can be created from 50.

Answer:

125 cubic inches

Step-by-step explanation:

The formula for the volume of a cube is:

[tex]V=a^3[/tex],

Where V is volume and a is edge length. Let's substitute the edge length of 5 from the problem into this formula.

[tex]V=5^3[/tex]

Now we can simplify. I will rewrite 5 cubed as 5*5*5 for simplicity.

[tex]V=5*5*5[/tex]

[tex]V=125[/tex]

So we have our volume, 125, but what does this mean? We have to figure out the units. Recall that our original unit was inches, thus the final answer is in inches. However, 125 inches does not make much sense, as we are dealing with volume, and not a line or distance. 125 cubic inches is the answer we are looking for, as cubic inches is the unit for volume deriving from inches.

To calculate the composite function (f ∙ g)(-1) for the functions f(x) = x² + 3 and g(x) = 4x - 3, we first find g(-1) which is -7, and then calculate f(-7) which results in 52.

To find the composite function (f ∙ g)(x), we first apply the function g to x, and then apply the function f to the result of g(x). In this case, first find g(-1) and then apply f to that result.

Initialize with g(-1), which is 4(-1) - 3. Simplifying that, we get -4 - 3, which equals -7.

Now, take the result of g(-1), which is -7, and input it into f(x) to get f(g(-1)). Thus, f(-7) = (-7)² + 3. Calculating this gives us 49 + 3, which equals 52. Therefore, (f ∙ g)(-1) = 52.

She would make $573.5 in a work if she sold $4,700 worth of merchandise

Step-by-step explanation:

The given is:

We need to find how much she would make in a work week

∵ Mae Ling earns a weekly salary of $315

∵ She earns a 5.5% commission on sales

∵ She sold by $4,700 in that week

- Add $315 to the product of 5.5% and $4,700

∴ She made = 315 + (5.5% × 4,700)

∵ 5.5% = 5.5 ÷ 100 = 0.055

∴ She made = 315 + (0.055 × 4,700)

∴ She made = 315 + 258.5

∴ She made = 573.5

She would make $573.5 in a work if she sold $4,700 worth of merchandise

Answer: The three consecutive numbers are 23, 24 and 25, and 25 Is obviously the largest.

Step-by-step explanation:

Answer: 23 , 24 , 25

Step-by-step explanation:

Consecutive numbers are numbers that follow each other in order.

Let the first number be x , the second number be x + 1 and the third number number be x + 2.

From the first statement :

Their sum implies :

x + x +1 + x + 2 = 72

3x + 3 = 72

Subtract 3 from both sides of the equation:

3x + 3 - 3 = 72 - 3

3x = 69

Divide through by 3

3x/3 = 69/3

Therefore :

x = 23

Therefore :

The numbers are

Answer:

24,393 subscribers

Step-by-step explanation:

This is exponential decay problem. The formula for exponential decay is:

[tex]F=P(1-r)^t[/tex]

Where

F is the future value (what we are looking for, in 7 years)

P is the present amount (that is 51,000)

r is the rate of decrease per year (r = 10% = 10/100 = 0.1)

t is the time, in years (t = 7)

Now substituting, we get:

[tex]F=P(1-r)^t\\F=51,000(1-0.1)^7\\F=51,000(0.9)^7\\F=24,393.14[/tex]

Rounding to nearest whole number,

Number of subscribers after 7 years = 24,393 subscribers

Using the exponential decay formula, a magazine with an initial 51,000 subscribers will have approximately 24,393 subscribers left in 7 years if subscriptions decline by 10% annually.

The question is asking to predict the number of magazine subscribers after a period of 7 years, assuming a 10% annual decline. To calculate this, we can use the formula for exponential decay, which is A = P(1 - r)^t, where A is the amount after time t, P is the initial principal amount (51,000 subscribers), r is the rate of decline (10% or 0.10), and t is the time in years (7 years). Calculating this, we get:

Now, calculate the value of A:

A = 51,000(1 - 0.10)^7

A = 51,000(0.90)^7

A = 51,000(0.4782969)

A ≈ 24,393 subscribers (after rounding to the nearest whole number).

Therefore, if the magazine subscriptions continue to decline at a rate of 10% per year, the magazine is predicted to have approximately 24,393 subscribers in 7 years.

The distance between the point where the cable is 1.44 inches above the roadway and the base of the nearest tower is : [tex]\[\(28 \text{ inches}}\][/tex].

To find the distance between the point where the cable is 1.44 inches above the roadway and the base of the nearest tower, we need to understand the mathematical model for the suspension bridge cable. This cable typically forms a parabolic shape.

Let's establish our coordinate system:

- Place the origin [tex]\((0, 0)\)[/tex] at the lowest point of the cable.

- The towers are at [tex]\(x = -40\)[/tex] inches and [tex]\(x = 40\)[/tex] inches since they are 80 inches apart.

- The height of the towers is 16 inches.

The equation of the parabola can be written in the vertex form [tex]\(y = ax^2\)[/tex] since the vertex is at the origin [tex]\((0, 0)\)[/tex].

At the position of the towers (x = ±40 inches), the cable is 16 inches high:

[tex]\[y(40) = 16\][/tex]

[tex]\[a(40)^2 = 16\][/tex]

[tex]\[1600a = 16\][/tex]

[tex]\[a = \frac{16}{1600} = \frac{1}{100}\][/tex]

So, the equation of the parabola is:

[tex]\[y = \frac{1}{100}x^2\][/tex]

We need to find the point where the cable is 1.44 inches above the roadway:

[tex]\[\frac{1}{100}x^2 = 1.44\][/tex]

[tex]\[x^2 = 1.44 \times 100 = 144\][/tex]

[tex]\[x = \pm\sqrt{144} = \pm 12\][/tex]

Therefore, the points where the cable is 1.44 inches above the roadway are [tex]\(x = 12\)[/tex] inches and [tex]\(x = -12\)[/tex] inches.

The distance from [tex]\(x = 12\)[/tex] inches to the nearest tower at [tex]\(x = 40\)[/tex] inches is:

[tex]\[40 - 12 = 28 \text{ inches}\][/tex]

Similarly, the distance from [tex]\(x = -12\)[/tex] inches to the nearest tower at [tex]\(x = -40\)[/tex] inches is:

[tex]\[-12 - (-40) = 28 \text{ inches}\][/tex]

Thus, the distance between the point where the cable is 1.44 inches above the roadway and the base of the nearest tower is:

[tex]\[\boxed{28 \text{ inches}}\][/tex]

The graph that shows the solution set for the inequality -5/2x -3<2 is a number line with an open circle at -2 and an arrow pointing to the left.

To graph the solution set for the inequality -5/2x -3<2, you first need to solve the inequality for x.

-5x -6 < 4

-5x < 4 + 6

-5x < 10

x < -2

The graph of the solution set for the inequality x < -2 is a number line with an open circle at -2 and an arrow pointing to the left. The open circle indicates that -2 is not included in the solution set, and the arrow pointing to the left indicates that all values to the right of -2 are included in the solution set.

Answer:

x = 2y + 6

Step-by-step explanation:

2x - 4y = 12

2x = 4y + 12

x = 2y + 6

To solve for 'X' in the equation 2x - 4y = 12, isolate 'X' by adding 4y to both sides, resulting in the equation 2x = 4y + 12. Further, divide the entire equation by 2 to get X = 2y + 6. The final value of 'X' would depend on the value of 'Y'.

To solve for X in the equation 2x - 4y = 12, we can proceed in the following manner:

Isolate X on one side of equation. In order to do this, we add 4y to both sides of the equation, thus changing the equation to 2x = 4y + 12.

Now, to solve for X, we need to divide the entire equation by 2. Therefore, the final equation is ready: X = 2y + 6.

Thereby, you have now solved for 'X' in the equation. Kindly note that as there is a 'y' variable involved as well, the final value of 'X' would depend on the value of 'Y'.
