Help no guessing please explain how to solveJulie earned simple interest on $8250 with an annual interest rate of 3.9% for 7 years. How much did she earn in interest? Round your answer to the nearest cent.

simple interest: I = P • r • t

Answer_______

Answers

Answer 1

Answer: ok so easy

I=PRT
t=time=7
r=rate3.9%=0.039
p=principal=8250

I=8250 times 0.039 times 7
I=8250 times 0.273
I=2252.25

$2252.25

Answer 2

Answer: We meet again. I see you are asking about another similar equation, and I will give you the same response I did last time. You simply plug the values into the equation in solve, so it would look like this:
I=8,250*.039*7.
And you can do the rest. I hope this was helpful, have a nice day! :)

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.

Jeremiah always bicycles to and from work. The total length of a trip is 14.6 kilometers.Last month,Jeremiah worked 18 days. How many kilometers did he bicycle to and from work last month?

Answers

14.6*18= 262.8
So, Jeremiah bicycled 262.8 kilometers to and from work in 18 days
Hope this Helps :D

Ok so if the total length of the trip was 14.6 you would multiply that by 18 because that's the number of times he worked and so you get 262.8 so that would be your answer if I'm not mistaken

What would the answer for X be ??

Answers

Answer:

140°

Step-by-step explanation:

The external angle is half the difference between the intercepted arcs. One arc is shown as 30°. The other will be the difference between 180° and (30°+x). Then we have ...

(30 -(180 -(30+x)))/2 = 10

x -120 = 20 . . . . . . . multiply by 2 and simplify

x = 140 . . . . . . . . . . . add 120

The measure of arc X is 140°.
