A whole number k is greater than 3. Which of the following is true about k/3?

Answers

Answer:

D) It is greater than 1.

Step-by-step explanation:

Since k is greater than 3, it could not be between 0 and 1/3 and also could not be between 1/3 and 1

We also know that it is not equal to 1 because it is greater than 3.

Therefore, it is greater than 1.

There are 365 days in a year and 24 hours in a day. An airport camera records for 18 hours and then automatically resets itself to start recording again how many times does the video camera reset itself in a year.
pls help

Answers

The answer is 486.6

There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6

Answer:

Step-by-step explanation:

You could do it this way.

How many hours are there in a year?

365 * 24 = 8760 hours.

This camera does not recognize days. It works on hours. Every 18 hours it resets. So

8760/18 = 486  and 2/3 times.

Obviously it cannot have 2/3 of a day. Normally you would round up, but this time you round down.

The answer is 486 times.

2/3 * 24 = 16

The camera would reset 2 hours into the next day.

Which statement correctly compares the function shown on this graph with
the function y= 4x+2?
1 2 3 4 5
O A The function shown on the graph has a greater rate of change and
a higher starting point
O B. The function shown on the graph has a smaller rate of change, but
a higher starting point
O C. The function shown on the graph has a smaller rate of change and
a lower starting point
O D. The function shown on the graph has a greater rate of change but
a lower starting point

PLEASE ANSWER

Answers

Answer:

B. The function shown on the graph has a smaller rate of change, but a higher starting point.

Step-by-step explanation:

Rate of change = slope of a linear graph.

Given the linear function, [tex] y = 4x + 2 [/tex] , the rate of change here is represented by the slope of the line, which is 4.

Let's find the rate change of the function represented on the graph using slope formula:

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Use coordinates of any two points on the line. Let's take,

[tex] (0, 4) = (x_1, y_1) [/tex]

[tex] (1, 7) = (x_2, y_2) [/tex]

Rate of change = [tex] \frac{7 - 4}{1 - 0} = \frac{3}{1} = 3 [/tex]

Rate of change of the linear function of the graph = 3.

Thus the function on the graph has a smaller rate of change, than the function, y = 4x + 2.

The starting value of a function is the y-intercept, that is, the value of y, when x = 0. It is the point at which the line intercepts the y-axis.

The starting value of the linear function, y = 4x + 2 is 2.

The starting value of the function on the graph is 4. At this point, x = 0.

Thus, the function on the graph has a higher starting point.

The statement that correctly compares the function shown on this graph with the function y= 4x+2 is:

B. The function shown on the graph has a smaller rate of change, but a higher starting point.

The population has decreased by 300 residents over the past 5 years. The same number the same number of residents left each year what was the change in the towns population each year

Answers

Answer:

-60

Step-by-step explanation:

Increase in population is given by positive sign

Change in population in 5 years = -300

Decrease in population is represented by negative sign

Change in population in 1 year = -300\5

                                                = -60

Town's population faces a decrease of 60 residents each year.

Step-by-step explanation:

It’s 37 degrees. If you look at one straight line, both sides have to equal 180. So take 180-37 and that’s the answer to CBD. Then you take THAT and subtract it from 180, which is 37. That’s the complicated way of explaining it. Since it’s right across it’s 37.

Tina is saving to buy a notebook computer. She has two options. The first option is to put $300 away

month. After how many months would Tina save the same amount using either option? How much
would she save with either option?
Plzzz hellpppp

Answers

Answer:

After 5 months, she will save the same amount using either option.

She would have saved $450 with either option.

Step-by-step explanation:

Set up expressions to represent the amount of money saved for each saving option, where x is the number of months

The first one can be represented by 30x + 300

The second one can be represented by 50x + 200

Set these equal to each other and solve for x:

30x + 300 = 50x + 200

300 = 20x + 200

100 = 20x

5 = x

So, after 5 months, Tina will save the same amount of money with both options.

To find how much she will save, plug in 5 as x into either expression:

30x + 300

30(5) + 300

150 + 300

= 450

So, she would have saved $450 with either option.

Suppose your business has a special checking account used just for paying the phone bill. The balance is $1530.00 this month. Next month the balance will be $1496.30, after that it will be $1432.60, and on the third month the balance will be $1428.90. Write an explicit formula to represent the balance in the account as an arithmetic sequence. How many months can you pay your phone bill without depositing any more money in the account?

A) An= 1530 + (n-1) ( -33.70); 46 months

B) An = 1530 + (n-1) (-33.70); 45 months

Please explain for me how you got the answer. Thank you so much

The water level of a lake fell by 1 1/2 inches during a 1 2/3-week-long dry spell. Find the average rate at which the water level changed every week.

Answers

Answer: The average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.

Step-by-step explanation:

Given: Change in water level in [tex]1 \dfrac23[/tex]  week = [tex]-1\dfrac12[/tex] inches = [tex]-\dfrac32[/tex] icnhes

To find : The average rate at which the water level changed every week.

i.e. Change in water level per week.

As [tex]1\dfrac23 = \dfrac52[/tex]

Change in water level in 1 week = [tex]-\dfrac{3}{2}\div\dfrac52 = -\dfrac32\times \dfrac25= -\dfrac35[/tex]

Hence, the average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.

We want to find the average rate of change at which the water level changed in a given time period.

We will find that the average rate of change is:

[tex]r = - 0.9 in/week[/tex]

We define the average rate of change as the quotient between the total change and the time it takes.

Here we have:

total change = -(1 + 1/2) in

Time = (1 + 2/3) weeks

Then the average rate of change is:

[tex]r = \frac{-(1 + 1/2) in}{(1 + 2/3) weeks} = - 0.9 in/week[/tex]

This means that the water level decreases, in average, 0.9 inches per week.
