For a $250,000 mortgage, with an interest rate of 6% paid over 25 years, the monthly payment is $1,610.75. After one month, what is the balance of the loan?
Round your answer to the nearest dollar.
Do NOT round until you calculate the final answer.
The balance on the loan after a month is $623389.25.
How to calculate the interest?The following can be deduced from the information given:
Principal = $250000
Time = 25
Rate = 6%
Interest = (Principal × Rate × Time) / 100
Interest = (250000 × 6 × 25) / 100
Interest = $375000
The total amount will be:
= Principal + Interest
= $250000 + $375000
= $625000
The balance of the loan will be:
= Amount - One month payment
= $625000 - $1,610.75
= $623389.25

There is a pair of natural numbers whose sum is 52 and whose product is 667. The positive difference of their reciprocals is __
The positive difference the numbers is given as 6.
What is the positive difference of their reciprocals ?We are told here that there is a pair of natural numbers whose sum is 52 and whose product is 667. We have to make use of the idea of simultaneous equations to obtain the numbers.
Let the numbers be x and y thus we have;
x + y = 52 ---- (1)
xy = 667 ------ (2)
x = 52 - y ------ (3)
Substituting (3) into (2)
(52 - y)y = 667
52y - y^2 = 667
y^2 - 52y + 667 = 0
Solving the quadratic equation we have;
y=23 or y=29
The difference between the numbers then becomes 29 - 23

How many hours did Anita work and what was her net pay ? Anita works 31 hours next week what is her gross pay total amount of deductions and net pay assuming the same percentage is taken out for each deductions during the next pay period ?
For the gross pay of $238.61 and given deduction Anita's net pay is equal to $181.59 at the rate of $9.45 per hour and she works for 25.25 hours.
When Anita works for 31 hours with the given conditions her gross pay and net pay is equal to $292.95 and $235.93 respectively.
As given in the question,
a. Anita get pay per hour = $9.45
Gross pay received by Anita = $238.61
Deductions :
Federal tax = $28.63
Society tax : $14.79
Medicare : $3.46
State tax : $10.14
Total deduction = $ ( 28.63 + 14.79 + 3.46 + 10.14 )
= $57.02
Net pay = Gross pay - total deduction
= $ ( 238.61 - 57.02 )
= $ 181.59
Let us consider Anita works for 'h' hours at the rate of $9.45,
9.45h = 238.61
⇒ h = 238.61/ 9.45
⇒ h = 25.25 hours
b. When Anita works for 31 hours
Her gross pay = 31 × 9.45
= $ 292.95
Deductions are same
Net pay = $ ( 292.95 - 57.02 )
= $ 235.93
Therefore, for the gross pay of $238.61 and given deduction Anita's net pay is equal to $181.59 at the rate of $9.45 per hour and she works for 25.25 hours.
When Anita works for 31 hours with the given conditions her gross pay and net pay is equal to $292.95 and $235.93 respectively.

This table gives a few (x, y) pairs of a line in the coordinate plane.
x
Y
-54
-21
-40
-14 -26
- 28
What is the y-intercept of the line?
The y-intercept of the line is y = 2
What is an intercept?
A line's x-intercept and y-intercept are the points at which the x- and y-axes, respectively, are crossed.
Here,
A linear function has the following equation:
y = mx + b
Where m is the slope and b is the y-intercept, which is the value of y when x = 0.
We have given three points:
(-28, -54)
(-21, -40)
(-14, -26)
We use two of them to construct a system, to find values for m and b.
(-28, -54)
This means that when x = - 28 , y = - 54
so, y = mx + b
- 54 = - 28m + b
28m = b + 54
m = (b + 54)/28
Now, we have x = -21, y = -40
so, y = mx + b
- 40 = - 21m + b
we put the value of m here
- 40 = - 21 {(b + 54)/28} + b we get,
7b - 1134 = - 40 × 28
b = 2
Hence, the y-intercept of the line is y = 2

Seth is planning a route for a train that travels at a constant rate of 220 kilometers per hour.
They want to write an equation that shows how many hours (t) a trip takes in terms of the trip's
distance (d).
t = d/220 is the equation that shows how many hours (t) a trip takes in terms of the trip's distance (d).
Define the relationship between distance, speed, and time.Speed is calculated as follows: speed = distance/time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is recorded in seconds, the units in this example will be meters per second (m/s) (s).
Let the distance be d and the time is t.
The given speed of the train = 220km/hr
Time = d/speed
t = d/220
This is the equation that shows how many hours (t) a trip takes in terms of the trip's distance (d).

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.
On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.
Consider your square as being composed of smaller unit squares. The number of unit squares necessary to completely cover the surface area of a specific 2-D shape is used to calculate the area of a figure. Some common units for measuring area include square cms, square feet, square inches, square meters, etc.
Let Width= x feet

The two expressions equivalent to v are:
5*(3a - 1) - 2*(3a + 2) - 3*(a + 2) = v6a - 15 = vHow to find the two expressions equivalent to v?Here we have the equation:
5*(3a - 1) - 2*(3a + 2) = 3*(a + 2) + v
And we want to find expressions equivalent to v, so to do that, we just need to isolate the variable v in one side of the equation, if we subtract:
3*(a + 2) in both sides we will get:
5*(3a - 1) - 2*(3a + 2) = 3*(a + 2) + v
5*(3a - 1) - 2*(3a + 2) - 3*(a + 2) = v
That is one of the equivalent expressions, to get the other, we can just simplify the left side.
5*(3a - 1) - 2*(3a + 2) - 3*(a + 2) = v
15a - 5 - 6a - 4 - 3a - 6 = v
Now we can group like terms:

Here we need to find if cos(x)=5/6 , and x is in quadrant I, determine the exact value of each of the following.
sin(x/2), cos(x/2), tan(x/2).
According to the concepts in trigonometry,
We know that the following formulas.
=> sin(x/2) = √(1-cosx)/2
=> cos(x/2) = √(1+cosx)/2
=> tan( x/2)=sin x/1+cosx
Here we know that cos (x) = 5/6
Thus implies that 5 is the opposite and 6 is the hypotenuse, then the adjacent is
Therefore, we can calculate the value of the adjacent a as,
=> a = √(6²-5²)
=> a = √36-25
=> a= √11
Therefore the value of sin x= √11/6
So, the value of sin(x/2)= √(1 - 5/6)/2
And the value of cos(x/2)= √(1 + 5/6)/2

Step-by-step explanation:
You want the scale of a map on which 4.2 cm corresponds to an actual distance of 6.2 km.
ScaleThe scale of a drawing is the ratio of drawing distance to actual distance. It can be expressed a couple of ways. We can write the given scale as ...
4.2 cm : 6.2 km
or, we can reduce it to ...
2.1 cm : 3.1 km
Often, we like to have a single unit of map distance in this ratio, which would make it be approximately ...
1 cm : 1.47619 km
FractionAnother way to write the scale of a map is as a fraction.
(4.2 cm)/(6.2 km) = (0.042 m)/(6200 m) = 21/3100000
When this is expressed as a unit fraction, the denominator is a repeating decimal with a 6-digit repeat. We can round it to ...
