Answer:

Area = 35

Step-by-step explanation:

Triangle formula= Base x Height divided by 2.

The base is the distance between the x-axis(-4 and 6) which is 10.

The height is the y axis distance(2 and 9) which is 7.

10 x 7 = 70

70/2 = 35

What is the better buy 1. 2 trains for $25 or 2.6 trains for 90$

creativ13 [48]

Answer:

1.2 trains for $25.

Step-by-step explanation:

For 50 dollars, you could get 2.4 trains with the $25 dollar option.

For 90 dollars (an extra 40 dollars!) you only get 0.2 more trains.

If you add another $25 to the current $50 on the other option, you get 3.6 trains.

So, 1.2 trains for $25 must be the better option as you can get an extra 1 train for 15 dollars less!

Hope this helps!

Also, who buys 0.2 or 0.6 of a train? -_-

Write the coordinates of the vertices after a reflection over the line y=3?

ehidna [41]

Answer:

L(4,-3) -> L'(4,9)

M(4,3) -> M'(4,3)

N(-4,3) -> N'(-4,3)

K(-4,-3) -> K'(-4,9)

Step-by-step explanation:

Reflection of an object means to flip that object on a line called the axis of reflection or line of reflection or mirror line.

Line of reflection here is y = 3

So, after a reflection over the line y = 3

Co ordinates

L' = (4,9)

M' = (4,3)

N' = (-4,3)

K' = (-4,9)

Cathy takes out a $178,000 mortgage to be paid off over the span of 30 years. Cathy computers the APR at the end of the loan and

Makovka662 [10]

Answer:

The interest of the mortgage is 72.2% of the total payment amount .

Step-by-step explanation:

The principal mortgage amount = P = $178,000

Let The amount after 30 years = $A

The period for which money mortgage = n = 30 years

The rate at which money mortgage for 30 years = 4.37%

Let the interest is x % of the total payment amount

From Compound interest method

The amount after 30 years =The principal mortgage amount × $(1+\dfrac{\textrm rate}{100})^{\textrm time}$

i.r A = P × $(1+\dfrac{\textrm r}{100})^{\textrm n}$

Or, A = 178,000 × $(1+\dfrac{\textrm 4.37}{100})^{\textrm 30}$

Or, A = 178,000 × $(1.0437)^{30}$

Or, A = 178,000 × 3.6080

Or, A = $642224

So, The amount after 30 years = A = $642224

Now, Interest = Amount - Principal

Or, I = $A - $P

Or, I = $642224 - $178,000

∴ Interest = I = $464,224

So, The interest of the mortgage = I = $464,224

Now, Again

interest = x % of total payment amount

So, $464,224 = $\dfrac{x}{100}$ × $642224

∴ $\dfrac{x}{100}$ = $\dfrac{464224}{642224}$

∴ $\dfrac{x}{100}$ = 0.722

i.e x% = 0.722

So, The interest is 72.2% of total payment

Hence,The interest of the mortgage is 72.2% of the total payment amount . Answer
