Final answer:

The equation can then be solved to find the value of 'm', representing the minutes of talk time. In this case, the answer is 68 minutes of talk time each month.

Explanation:

To find the minutes of talk time you use each month, we can set up an equation based on the given information. Let's assume that the number of minutes of talk time you use each month is represented by 'm'.

The total cost for all 6 months is $195.12, which is equal to the sum of the monthly costs. Each month, the cost of the cell phone plan is $23.70 for 700 minutes of talk time, plus an additional $0.06 per minute for each minute over 700 minutes. Additionally, to get email access, it costs 20% of the price for 700 minutes of talk time.

Based on this information, the equation is: 195.12 = 6(0.06m + 23.70 + 0.20(23.70))

To solve the equation, we can simplify it: 195.12 = 6(0.06m + 23.70 + 4.74)

195.12 = 6(0.06m + 28.44)

Divide both sides of the equation by 6, we get: 32.52 = 0.06m + 28.44

Subtract 28.44 from both sides of the equation, we get: 32.52 - 28.44 = 0.06m

4.08 = 0.06m

Divide both sides of the equation by 0.06, we get: m = 68

Therefore, you use 68 minutes of talk time each month.

Final answer:

After setting up the equation based on the total cost for 6 months, we calculate that the user talks for a total of 768 minutes each month. This includes the 700 minutes in the plan and an additional 68 minutes of talk time.

Explanation:

To solve for the number of minutes of talk time used each month, we first set up an equation based on the information given. The total cost for 6 months is $195.12 which includes the monthly plan cost, the additional cost per minute after 700 minutes, and the email cost which is 20% of the 700 minutes talk time plan.

The equation, therefore, is 195.12 = 6(0.06m + 23.70 + 0.20(23.70)), where m is the number of minutes used over 700. Let's solve the equation step-by-step:

Therefore, you use 68 minutes over the 700 included minutes, which means you use a total of 700 + 68 = 768 minutes of talk time each month.

Answer:

Y = 64°

Step-by-step explanation:

The internal angles of a triangle sum to 180°

So by subtracting the known angles from the angle sum you can find Y

Y = 180° - 37° - 79° = 64°

Answer:

First you should simplify the inequality and get n by itself:

3n - 10 ≥ 2      Add 10 on both sides

3n ≥ 12       Divide 3 on both sides

n ≥ 4

When the sign is ≤ or ≥ (less/greater than or equal to), the line is a solid line.

When the sign is < or >, the line is a dotted line.

If the variable is > than the function (like y > 3x + 2, or x > 2y²) The shaded area is above the line (or going in the positive direction)

If the variable is < than the function (like x < 2, or x < 5z - 7), The shaded area is below the line.

Since we got n ≥ 4,

If n is an x value, or n = x, you would have a horizontal line at y = 4, but if n is a y value, n = y, you would have a vertical line at x = 4. The shaded area should be above the line, or to the right of the line since n is > 4. (Sorry, I don't know if n = y or n = x, hope this clarified things)

Answer:

n ≥4

Step-by-step explanation:

3n -10 ≥ 2

Add 10 to each side

3n -10+10 ≥ 2+10

3n ≥12

Divide by 3

3n/3 ≥12/3

- 15x² + 7x + 1

Step-by-step explanation:

Given

2x² - 9 - 17x² + 10 + 7x ← collect like terms

= (2x² - 17x² ) + 7x + 1

= - 15x² + 7x + 1

The cost of the unfurnished and furnished apartments for 1 year would be $8,650 and $9,880 respectively. Therefore, the unfurnished apartment is the better deal for Jonathan.

The cost for the unfurnished apartment for one year would be $600 (monthly rent) * 12 (months) + $600 (one month deposit) + $350 (security deposit) + $850 (furniture cost) = $8,650.

The cost for the furnished apartment for one year would be $190 (rent per week) * 52 (weeks in a year) = $9,880.

Therefore, the unfurnished apartment offers a better deal for Jonathan if he plans to stay for 1 year.

The graph in the attached figure

Step-by-step explanation:

we have

[tex]y=\frac{3}{4}x-4[/tex]

This is a linear equation (the graph is a line)

To identify the graph find out the intercepts

Find out the y-intercept

The y-intercept is the value of y when the value of x is equal to zero

For x=0

[tex]y=\frac{3}{4}(0)-4=-4[/tex]

The y-intercept is the point (0,-4)

Find out the x-intercept

The x-intercept is the value of x when the value of y is equal to zero

For y=0

[tex]0=\frac{3}{4}x-4[/tex]

[tex]\frac{3}{4}x=4[/tex]

[tex]x=16/3=5.33[/tex]

The x-intercept is the point (5.33,0)

therefore

The graph in the attached figure

The graph of the linear function y = x 3/4–4 can be generated by understanding that '3/4' is the slope and '-4' is the y-intercept. This implies for every horizontal increase of 4 units, there's a vertical rise of 3 units. The function intersects the y-axis at -4.

The linear function in question, y = x 3/4–4, can be graphed by understanding how the terms within the equation shape the line. The term '3/4' in the equation is the slope of the line and '–4' is the y-intercept. The slope or the rate of change is less than 1 which means for every increasing step in 'x', 'y' increases by less of a step (3/4 of a step, in this case). The linear function intersects the y-axis at -4. Therefore, when you plot x and y values, keep in mind that for every rise of 3 on the vertical axis, there's an increase of 4 on the horizontal axis. Start by marking the y-intercept (0, -4) and use the slope (3/4) to find the next points. From the y-intercept, move 3 units up and 4 units to the right. Repeat this pattern to generate other points that lie on the line.

Answer:

Surface Area: 2123.72

Volume: 9202.77

Density: 0.0078

Step-by-step explanation:

For a sphere, the height is the diameter.

Also we know the radius is half of the diameter.

Since height is 26, diameter is 26 as well. Thus, radius is half of 26, which is 13.

Formulas:

Surface area of sphere = 4πr^2

Volume of sphere = [tex]\frac{4}{3}\pi r^3[/tex]

Density = mass/volume

Firstly, the surface area:

[tex]4\pi r^2\\=4\pi (13)^2\\=2123.72[/tex]

Next, the volume:

[tex]\frac{4}{3}\pi r^3\\=\frac{4}{3}\pi (13)^3\\\\=9202.77[/tex]

Lastly, density:

Let iron = x

There is 1.5 times the amount of zinc that there is iron, so you get zinc = 1.5x

There is 3 times as much copper as there is zinc, so 1.5 x 3 = 4.5, so copper equals 4.5x

Now all three need to equal the total weight of 210:

X + 1.5x + 4.5x = 210

Simplify:

7x = 210

Divide both sides by 7:

x = 210 /7

x = 30

Now you have a value for x, you can solve for the amount of each material.

Iron = x = 30 g

Zinc = 1.5x = 1.5(30) = 45 g

Copper = 4.5x = 4.5(30) = 135g

There is 45 g of zinc.

Let iron =x

There is 1.5 times the amount of zinc then there is iron, so zinc = 1.5x

There is 3 times as much copper then there is zinc, so 1.5*3=4.5, so copper equals 4.5x

Answer:

k=(-7y+11)/4

Step-by-step explanation:

Given

11(k-1)= 7(k-y)

In order to find the value of K we have to separate k on one side, so

Multiplying 11 and 7 into the brackets on both sides

11k-11=7k-7y

Subtracting 7k on both sides

11k-11-7k=7k-7y-7k

11k-7k-11= -7y

Adding 11 to both sides

4k-11+11= -7y+11

4k= -7y+11

4k=-7y+11

k=(-7y+11)/4

So the value of K is (-7y+11)/4.
