Josiah cell phone plan allows a number of minutes of air time for $20 a month each minute costs 0.02 $ how many minutes of air time is he allowed?

Answers

Given parameters:

Cost of cell phone plan per minute  = 0.02$/min

Amount in a month  = $20

Unknown:

Number of minutes allowed per month?

Solution:

 The number of minutes = [tex]\frac{amount per month}{rate per call}[/tex]

     Input the parameters and solve;

                                         = [tex]\frac{20}{0.02}[/tex]

                                         = 1000min

The number of minutes allowed per month is 1000min

Maurice's shirt has five buttons that are vertically arranged and equally spaced. His shirt is shown in the photo below. The first and last buttons are 15.25 inches apart when measured from the top of the first button to the top of the last button. What is the distance, in inches, between the top two buttons on his shirt, from the top of one to the top of the other? Round your answer to the nearest tenth.

Answers

Answer:

The distance between the top two buttons on his shirt is 3.8 inches.

Step-by-step explanation:

Maurice's shirt has 5 buttons. Distance between first and last button is 15.25.

If we see, they would be arranged like

*

*

*

*

*

They are equally spaced between each button.

So, there are 4 equal spaces between the buttons.

Distance between each two consecutive buttons =[tex]\frac{15.25}{4}[/tex] =3.8125

So, distance between the top two buttons on his shirt is 3.8 inches.

The number line below represents which combined inequality? (10 points)

x greater than or equal to −6 and x less than or equal to 5
x less than or equal to −6 and x greater than or equal to 5
x less than or equal to −6 or x greater than or equal to 5

Answers

Answer:

x is greater than or equal to −6 and x less than or equal to 5 (second option).

Step-by-step explanation:

This would be written as an "and" inequality; -6[tex]\leq[/tex]x[tex]\leq[/tex]5. Because the circle is closed on the number line, x is greater than or equal to −6 and x less than or equal to 5, and that's pretty much the answer!

An art student uses a roll of wallpaper to decorate two gift boxes. The student will use 3 1 3 yards of paper for one box and 5 6 yard of paper for the other box. The paper must be cut into pieces that are 1 6 yard long. How many pieces will the student cut to use for the gift boxes?

Answers

Answer:

25 pieces

Step-by-step explanation:

Given

[tex]Box_1 = 3\frac{1}{3}[/tex]

[tex]Box_2 = \frac{5}{6}[/tex]

[tex]Pieces = \frac{1}{6}[/tex] yard

Required

Determine the number of pieces

First, we need to determine the total yards of paper

[tex]Total = Box_1 + Box_2[/tex]

[tex]Total = 3\frac{1}{3} + \frac{5}{6}[/tex]

[tex]Total = \frac{10}{3} + \frac{5}{6}[/tex]

[tex]Total = \frac{20 + 5}{6}[/tex]

[tex]Total = \frac{25}{6}[/tex]

Divide by the size of the pieces to get the number of pieces

[tex]Number = Total/Pieces[/tex]

[tex]Number = \frac{25}{6} / \frac{1}{6}[/tex]

[tex]Number = \frac{25}{6} * \frac{6}{1}[/tex]

[tex]Number = \frac{25}{1} * \frac{1}{1}[/tex]

[tex]Number = 25[/tex]

So 3×5 is 15

20+15 = 35

Answer: 35 students

Explanation: Divide 4 into 20 to see how many sets of 4 girls there are. So there are 5 sets of four girls.

Five times three is 15.

In total (15 + 20), there are 35 students.

How old will you be when you have Received a total Of $4000 from aunt Isabell?

Answers

Answer:

20 years old

Step-by-step explanation:

Given

Base Amount = $10

Additional Amount = $20

Required

Determine the number of years where the total will accumulate to $4000

This question represents Sum of an AP series.

[tex]S_n = \frac{n}{2}(2a + (n - 1)d)[/tex]

Such that:

[tex]S_n = 4000[/tex]

[tex]a = 10[/tex]

[tex]d = 20[/tex]

Substitute these values in the above formula:

[tex]4000 = \frac{n}{2}(2 * 10 + (n - 1) * 20)[/tex]

[tex]4000 = \frac{n}{2}(20 + 20n - 20)[/tex]

[tex]4000 = \frac{n}{2}(20n)[/tex]

[tex]4000 = \frac{20n^2}{2}[/tex]

[tex]4000 = 10n^2[/tex]

Divide through by 10

[tex]400 = n^2[/tex]

Take square root of both sides

[tex]20 = n[/tex]

[tex]n = 20[/tex]
