What is simple interest?
Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.
The formula for calculation of simple interest will be:-
Interest = (P x R x T ) / 100
I = ( 14000 x 0.12 x 3 ) / 100
I = 5040
Add Interest to the Principal
14000 + 5040
Total amount = $19,040
Therefore the amount paid back by him altogether is 19040 dollars.

Answer:
276°
Step-by-step explanation:
In the figure attached, circle D is shown.
arc BA + arc AC + arc CB = 360°
(7n + 12) + (13n - 16) + 6n = 360
26n - 4 = 360
n = (360 + 4)/26 = 14°
arc BAC = arc BA + arc AC
arc BAC = (7n + 12) + (13n - 16)
arc BAC = 20n - 4
arc BAC = 20(14) - 4 = 276°
Answer:
The answer is 276 degrees. I checked on Khan Academy. The reason 84 degrees is NOT the answer is because that would be the minor arc, not the major arc.

y-y1=m(x-x1)
in your case m= -5 ; A(x1;y1)=(1;-1)
y-(-1)= -5(x-1)
y+1= -5(x-1)
answer is c
Answer:
The answer to the question is C) y + 1 = -5(x - 1)
Step-by-step explanation:
In order to find this, we start by looking at the base form of point-slope form.
y - y1 = m(x - x1)
Now we put the slope in for m and the point in for (x1, y1)
y + 1 = -5(x - 1)

The answers for both the parts are as (a) the rate of proofreading is 7.5 pages per hour and (b) The payment received for each page is $2,.67.
What is Unitary method ?
In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The pages proofread in 2 hours is 15.
The total amount received is $40.
(a) The proofreading rate can be known by dividing the total pages by total time as below,
Rate of proofreading = 15/2 = 7.5 pages per hour.
(b) As per the question the unitary method can be applied to obtain the payment for one page as follows,
Payment for proofreading 15 pages = 40
Thus, payment for proofreading one page is 40/15 = 2.67.
Hence, the proofreadingrate is 7.5 pages per hour and the average payment for each page is $2.67 respectively.

because 15 (number of pages) divided by 2 (number of hours) is 7.5.
B. $2.67
Because $40 divided by 15 (the number of pages) is $2.67
