You owe $31000 on student loans at an interest rate of 3.35% compounded monthly.
The total interest paid would be $556.16.The monthly payment would be $318.54.What is interest?Generally, To calculate the monthly payment amount, you can use the following formula:
monthly payment = (interest rate / 12) x (loan balance / (1 - (1 + (interest rate / 12)) ^ (-term in months)))
Plugging in the values given in the question, the monthly payment would be:
monthly payment = (3.35% / 12) x ($31000 / (1 - (1 + (3.35% / 12)) ^ (-8 years x 12 months/year)))
= (0.00335) x ($31000 / (1 - (1 + 0.00335) ^ (-96)))
= $318.54
So the monthly payment would be $318.54.
To calculate the total interest paid over the course of the loan, you can use the following formula:
total interest = (monthly payment x term in months) - loan balance
Plugging in the values given in the question, the total interest paid would be:
total interest = ($318.54 x 96 months) - $31000
= $30,443.84 - $31,000
= $-556.16

Draw the image of triangle ABC under a dilation whose center is A and scale factor is 4.
The image of triangle ABC under a dilation whose center is A and scale factor is 4 is as follows.
What is dilation?
Dilation involves changing the size of a shape.
Main body:
Assume point P is the center of origin, then we have the following coordinates of ABC
A= (1,0)
B= (-2,0)
C= (0,2)
The scale factor (k) is given as:
K = 4
So, the dilation rule is represented as:
(x, y) = 4 *(x,y)
Using the above dilation rule, the following coordinates represent the image of triangle ABC
A' =(4,0)
B' =(-8,0)
C' =(0,8)

Why do you think taxes have become more complicated since 1913?
Answer:
Before 1913, federal government revenues came mainly from taxes on goods—tariffs on imported products and excise taxes on items like whiskey.
Step-by-step explanation:
What was the tax rate in 1913?
The act levied a tax of one percent on all incomes above the exemption with additional surtax rates imposed for progressively higher incomes. Those surtax rates started at one percent for those making $20,000 or more and topped out at a mere six percent on incomes in excess of $500,000.

O y = - 4x-5
Oy = 4x + 11
O y = x + 1/
O y = -x + 1/
Answer:
[tex]y=\dfrac{1}{4}x+\dfrac{7}{2}[/tex]
Step-by-step explanation:
Given equation:
[tex]y=-4x-5[/tex]
If two lines are perpendicular to each other, their slopes are negative reciprocals.
The slope of the given equation is -4.
Therefore, the slope of the perpendicular line is ¹/₄.
[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Point-slope form of a linear equation}\\\\$y-y_1=m(x-x_1)$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $(x_1,y_1)$ is a point on the line.\\\end{minipage}}[/tex]
Substitute the found slope and point (-2, 3) into the point-slope formula to create the equation of the perpendicular line.
[tex]\implies y-3=\dfrac{1}{4}(x-(-2))[/tex]

What is an inequality ?An inequality in mathematics is a relationship that makes a non-equal comparison between two numbers or other mathematical expressions. It is most commonly used to compare the sizes of two numbers on a number line.
From given question :
-5x-3.5>6.5
-5x > 10
X > -50
Since, we have to solve for x
so, we will isolate x on anyone side
step-1:
Add both sides by 3.5
- 5x - 3.5 + 3.5 > 6.5 + 3.5
- 5x > 10
step-2:
Divide both sides by -5
we know that whenever we divide both sides by negative sign , it's inequality gets revered
so, we get
- 5x / -5 < - 50 / -5
we get
x < 10
so,
She should divide both sides by -5 while she multiplied by -5 on other side

It will take approximately ___years.
It takes 11.55 years for money to double if invested at 6% compound interest.
What is compound interest?
The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest.It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest.Compound interest is commonly abbreviated C.I. in mathematics.Calculating the answer exactly: P⁰°⁰⁶ⁿ=A .
We don’t know the initial value of the principal but we do know that the accumulated value is double (twice) the principal.
P⁰°⁰⁶ⁿ = 2P
We divide both sides by P
e⁰°⁰⁶ⁿ = 2
Using natural logarithm:
0.06 n = ln(2)
n = ln(2)/0.06
n = 11.55 years
Hence, It takes 11.55 years for money to double if invested at 6% compound interest.

Answer:

Step-by-step explanation:
Select all the equations that are equivalent to y-4 =2/3(x-1)
The equivalent equations of y - 4 = 2/3(x - 1) are y - 4 = 2/3x - 2/3 and y = 2/3x + 10/3
How to determine the equivalent equation?From the question, we have the following parameters that can be used in our computation:
y - 4 = 2/3(x - 1)
We start by expanding the bracket
So, we have the following representation
y - 4 = 2/3x - 2/3
Next, we add 4 to both sides of the equation
This gives
y - 4 + 4 = 2/3x - 2/3 + 4
Evaluate the like terms
So, we have the following representation
y = 2/3x + 10/3
Hence, the equivalent equation is y = 2/3x + 10/3

A total of 627 tickets were sold for the school play. They were either adult tickets or student tickets. There were 73 fewer student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
350
Step-by-step explanation:
Let "a" represent the number of adult tickets sold and "s" represent the number of student tickets sold. We can set up the following equation to represent the information given:
a + s = 627
s = a - 73
Substituting the second equation into the first equation gives us:
a + (a - 73) = 627
2a - 73 = 627
2a = 700
a = 350
Thus, there were 350 adult tickets sold.
How is a system of two linear inequalities in two variables different from a system of two linear equations in two variables?
Answer:
A system of two linear inequalities in two variables is a set of two linear inequalities that involve two variables, such as x and y. A system of two linear equations in two variables is a set of two linear equations that involve two variables, also typically x and y.
There are several key differences between a system of two linear inequalities in two variables and a system of two linear equations in two variables:
Inequalities use symbols such as "less than" or "greater than" to indicate the relationship between the variables, whereas equations use the equal sign (=).
The solution to a system of linear inequalities is a region in the coordinate plane, whereas the solution to a system of linear equations is a single point.
The solution to a system of linear inequalities is found by graphing the inequalities on the coordinate plane and finding the region where they intersect, whereas the solution to a system of linear equations is found by solving the equations for the values of the variables.
The solution to a system of linear inequalities may include an infinite number of points, whereas the solution to a system of linear equations is always a finite number of points.
Overall, the main difference between a system of two linear inequalities in two variables and a system of two linear equations in two variables is the way in which the solutions are represented and found.
Find the area of the shaded region in the figure. Round results to the nearest uni. Use 3.14
The Area of the shaded part is 3.44 cm²
Area of circle:The formula used to find the Area of a circle is given by
Area of circle = 2πrWhere r is the radius of the circle
Area of Square:The formula used to find the Area of a Square is given by
Area of Square = Side²
Here we know
The radius of the circle = 2m
As we know Area of a Circle = 2πr
=> Area of given circle = 2(3.14)2 = 12.56 cm²
Area of circle = 12.56 cm²
As we can see the circle is inscribed in a square
Then the Length of the side square = diameter of the circle
=> Length of side = 2 × Radius of circle = 2 × 2 cm = 4 cm
Length of side = 4 cm
As we know Area of the square = side²
=> Area of given square = 4 × 4 = 16 cm²
Now using the above value we will friend the area of the shaded part
Area of shaded part = Area of the square - Area of the circle
= 16 cm² - 12.56 cm² = 3.44 cm²
