If the loan offers no payments for the first 5 months, the amount owed by Dillion when he begins making the payments is $2,441.03

What is the effective monthly interest rate on the loan?

The effective monthly interest rate on the loan is determined as the annual percentage rate(APR) of 6.6% divided by 12 months since there are 12 months in a year

effective monthly interest=6.6%/12

effective monthly interest=0.0055

FV=PV*(1+r)^N

FV=the balance owed after 5 months=unknown

PV=the loan amount=$2375

r=effectively monthly interest rate=0.0055

N=number of months that have passed since the loan was taken=5

FV=$2375*(1+0.0055)^5

FV=$2,441.03

Answer:

y = 6h  h = hour

Step-by-step explanation:

As the length of the sides AD ≠ BC the given quadrilateral ABCD is not a parallelogram.

To prove that the given lines are parallel we have to determine their slope if the slope if equal then the lines are parallell.

We know that a quadrilateral is a parallelogram when opposite lines are of the same length and opposite lines are parallel to each other.

Given a quadrilateral, ABCD has coordinates A(−6,−1), B(−5,2), C(−1,−5), and D (0,−2).

∴ The quadrilateral ABCD t be a parallelogram length of AB = DC and length of AD = BC.

We know the distance formula is [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

So, lenght of AB = [tex]\sqrt{ (-5+6)^2 + (2 + 1)^2[/tex].

AB = [tex]\sqrt{ 1 + 9}[/tex].

AB = [tex]\sqrt{10}[/tex] units.

Lenght of DC = [tex]\sqrt{(0+1)^2 + (-2+5)^2}[/tex].

DC = [tex]\sqrt{10}[/tex] units.

Now length of AD = [tex]\sqrt{0+6)^2 + (-2+1)^2[/tex].

AD = [tex]\sqrt{ 37}[/tex] units.

Length of BC = [tex]\sqrt{(-1+5)^2 + (-5+2)^2[/tex].

BC = [tex]\sqrt{25}[/tex].

BC = 5 units.

As BC ≠ AD therefore quadrilateral ABCD is not a parallelogram.

The equation that shows the amount Christa and Megan each had in sales in July is 630 + 0.03x = 609 + 0.035x

An equation is used to show the relationship between numbers and variables. An equation can be linear, quadratic depending on the degree.

Let x represent the amount Christa and Megan each had in sales in July. Hence:

For Christa = 18(35) + 0.03x

For Megan = 21(29) + 0.035x

630 + 0.03x = 609 + 0.035x

Answer:

Step-by-step explanation:

When x = 20, y = 0

When x = 40, y = 10

When x = 60, y = 20

When x = 80, y = 30

When x = 100, y = 40

The slope is the change in y divided by the change in x.

First, find the change in x and y between any two points. We will use the first two points, (20, 0) and (40,10)

The change in x is 40 - 20 = 20

The change in y is 10 - 0 = 10

Divide the change in y by the change in x.

10 / 20 = 1/2

The slope is 1/2

The figure with these coordinates are G'(3, -5), H'(2, 0), I'(0, -1) and J'(-1, -4)  given below. Therefore, option C is the correct answer.

Given that the shape is reflected across the y-axis.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

The coordinates of the given figure are G(-3, -5), H(-2, 0), I(0, -1) and J(1, -4)

When the coordinates of the figure GHIJ are reflected across the y-axis we get G(-(-3), -5), H(-(-2), 0), I(0, -1) and J(-(1), -4)

So, the coordinates are G'(3, -5), H'(2, 0), I'(0, -1) and J'(-1, -4)

What is meant by Angle bisector?

Angle bisector is refer to a line that split an angle into two equal angles.

Given that;

Measure of ∠DEH = (10x - 2)°

Measure of ∠HEF = (6x + 10)°

Ray EH is angle bisector of ∠DEF.

Now, Ray EH is angle bisector of ∠DEF.

Hence,

1. Measure of ∠DEH = Measure of ∠HEF

Reason = Ray EH is angle bisector of ∠DEF.

2. (10x - 2)° =  (6x + 10)°

Reason = Measure of ∠DEH = (10x - 2)° and Measure of ∠HEF = (6x + 10)°

3. 10x - 2 - 6x = 6x + 10 - 6x

Reason = Subtract 6 both side.

4. 4x - 2 = 10

Reason = Apply sum or difference rule.

5. 4x - 2 + 2 = 10 + 2

Reason = Add 2 both side.

the probability that the sample contains two white balls and one green ball is 21/40.

In probability and statistics, an urn problem is an idealized mental exercise in which some objects of real interest (such as atoms, people, cars, etc.) are represented as colored balls in an urn or other container. One pretends to remove one or more balls from the urn; the goal is to determine the probability of drawing one color or another, or some other properties.

Total number of balls: 7 White and 3 Green = 10 balls

Cases for three balls are drawn at random:

Selection of 3 balls from 10 balls = [tex]^1^0C_3[/tex]

Case A: 1 White and 2 Green = [tex]\frac{^7C_1 * ^3C_2}{^1^0C_3} = \frac{7*3}{120} = \frac{21}{120} \\[/tex]

Step-by-step explanation:

The number of years it would take to double at 6% compounded annually is 11.55 years

The number of years it would take to double at 10.2% compounded annually is 6.8 years

When an amount earns at a compound interest, it means that the investment increases at an exponential rate. This means that the rate of growth in a new compounding period would be greater than the rate of growth at the previous compounding period.

When an amount is compounded monthly, it means that both the amount invested and the interest that has already been earned increases in value once a month, twelves times a year.

The formula that can be used to determine the number of years it would take the investment to double is:

Number of years it would take to double = In (FV / PV) / r

Where:

r = 6/12 = 0.5%

r = 10.2 /12 = 0.85%

Number of years it would take to double = In2 / 0.005 = 138.629 months

138.629 months / 12 = 11.55 years

Number of years it would take to double = In2 / 0.0085 = 81.547 months

81.547 months / 12 = 6.8 years

After solving the set of linear equation so formed, we conclude that value  of "S" and "J" is 4 and 5 respectively.

As per the question statement, A woman bought "S" shirts at $20 each and "J" jerseys at $ 15 each at a total Cost of $ 155. However, the total cost would have been $190 if she had purchased half as many shirts and twice as many jerseys. We are supposed to find the value of "S" and "J"

Let us first form the set of linear equation so formed.

Cost of one shirt = $20

Cost of "S" shirts = $20 x S = 20S

Cost of one jersey = $15

Cost of "J" jerseys = $15 x J = 15J

Total cost = $155

20S + 15J = 155 is our first linear equation obtained.

Now if however she bought half as many Shirts, and twice as many jerseys, then the total Cost would have been $190 and the equation formed will be :

20(S/2) + 15(2*J) = 190

or 10S + 30J = 190, is our second equation
