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 determine it to be 4.37%.what is the percent of the total payment is interest

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  ×

i.r A = P ×

Or, A = 178,000 ×

Or, A = 178,000 ×

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 = × $642224

∴   =  

∴   = 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

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
