Ending time: 10:08 am elapsed time: 30 minutes

Answers

Answer 1
Answer:

Answer:

Hence, beginning time is:

9:38 a.m.

Step-by-step explanation:

We know that:

" Elapsed time is the time or difference between a beginning time and an ending time "

Here we are given that the ending time is:

10:08 a.m.

and elapsed time is:

0:30 minutes.

This means the beginning time will be :

ending time - elapsed time.

Hence on counting back 30 minutes from 10:08 am we get the beginning time as:

9:38 a.m.
Answer 2
Answer:

We have to subtract 30 minutes from 10:08 am, then the elapsed time will be 9 hours 38 minutes.

What is subtraction?

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

Ending time: 10:08 am elapsed time: 30 minutes. Then the time will be

We know that elapsed means before 10:08 am. So we have to subtract 30 minutes from 10:08 am. Then we have

\begin{matrix} & 10 & : & 08 \n- & 00 & : & 30 \n& \overline{09} & : & \overline{38}\end{matrix}\n

Then the time will be 09:38 am.

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $135 for 100 minutes of usage and $375 for 500 minutes of usage. An equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph of y against x? Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 0.6 Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6 Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 1.67 Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 1.67

Answers

Answer:

The graph which describes the relationship between company charges and minutes of usage is the graph containing the points (100,135) and (500,375) and has a slope of 0.6. Where the first coordinate of the points are the minutes and the second coordinate the charges.

Step-by-step explanation:

As the first coordinate of a point always represents the x variable and the second coordinate they value, the possible options to describes this situation are:

  • The graph join which joins the points (100,135) and (500,375) and has a slope =0.6
  • The graph join which joins the points (100,135) and (500,375) and has a slope =1.6

The other options are not possible since the order of the coordinates is inverted.  

One of the possibilities showing above must be rejected since one have the incorrect slope. To verify the correct slope we calculate the variation of y coordinates and divide by the variation of x coordinates:

m=((y2-y1))/((x2-x1))

Assuming the point named '2' as the point (100,135) and the point named '1' as (500,375):

m=((375-135) \$)/((500-100) minutes)

m=((240) \$)/((400) minutes)

m=0.6 \$/minutes

Thus, that the graph joining the points (100,135) and (500,375) and has a slope of 0.6 the only possible action.
The correct answer to this question is letter "B. Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6." The one on the x axis should be the number of minutes and on the other hand, the one on the y axis should be the amount being charged.

Rosa is thinking of a number between 9.04 and 9.15 that has a 6 in the hundredths place what is the number? Explain

Answers

9.06

if the 6 is in the hundreths place, with those numbers it is the only answer because the next highest would be 9.16 and that would be too high
9.06 because 9.06 is greater than 9.04 but smaller than 9.15

I would like you to go deeper into the question but, okay so a fraction a part of a whole number okay? Also fractions can always be written as a decimal. Fractions have to forms improper and proper. Proper means it is like: 1 3/4.
But improper is: 7/4. That's all for now.

Answers

3 × x = 81

This is a multiplication problem. To solve for x you must divide 81 by 3.

So your answer is D. division.

its D) Division because you are going to divide both sides by 3 to get x by its self
