RoseWind [281]

Answer:

Step-by-step explanation:

x = width

4x - 16 = length

x + x + (4x - 16) + (4x - 16) = 68

= x + x + 4x - 16 + 4x - 16 = 68

= 10x - 32 = 68

= 10x = 100

= x = 10

width = 10 feet

length = 24 feet

Find the value of x in this figure

MArishka [77]

Answer: 35
Each triangle adds up to 180 degrees by adding the two angles that you already have the value of (37+108) and subtract it from 180 to get the final angle(x) you get 35

Therefore x=35 :)

Use a transformation to solve the equation. f – 12 = –35 A. f = –47 B. f = –23 C. f = 23 D. f = 47

andrew-mc [135]

F – 12 = –35

Here, we must solve for f

f - 12 = -35
+12 +12

f = -35 + 12
f = -23

Answer: f = -23

Michael obtains a 30/8 balloon mortgage to finance $425,500 at 6.55%. How much principal and interest will he have already paid

STALIN [3.7K]

Answer:

$259 532

Step-by-step explanation:

Step 1. Calculate the monthly payments on a 30-year loan.

The formula for the monthly payment (P) on a loan of A dollars that is paid back in equal monthly payments over n months, at an annual interest rate

of r % is

$P = A(\frac{r}{1-(1+r)^{-n}})$

We must express the interest rate on a monthly basis.

i = 6.55 %/yr = 0.545 83 %/mo = 0.005 4583

A = $425 500

n = 360 mo

<em>Calculation: </em>

$P = 425 500(\frac{0.005 4853}{1-(1+0.005 4583)^{-360}})$

$P = \frac{2332.22}{{1- {1.005 4583}}^{-360}}$

$P = \frac{2332.52}{1 – 0.140907}$

$P = \frac{2332.52}{0.859 093}$

P = $2703.46

B. Total Payment (T) after 8 years

T = nP

T = 96 × 2703.46

T = $259 532

Michael will have paid $259 532 at the end of eight years.

Find the values of XYNZ to the nearest integer

katen-ka-za [31]

Answer:

Part 1) The measure of x is 23°

Part 2) The value of y is $y=5\ units$

Part 3) The value of z is $z=12\ units$

Step-by-step explanation:

step 1

Find the value of x

we know that

$x+67\°=90\°$ ------> by complementary angles

$x=90\°-67\°=23\°$

step 2

Find the value of y

In the right triangle of the figure

$cos(67\°)=\frac{y}{13}$ -----> adjacent side angle of 67 degrees divided by the hypotenuse

$y=(13)cos(67\°)=5\ units$

step 3

Find the value of z

In the right triangle of the figure

$sin(67\°)=\frac{z}{13}$ -----> opposite side angle of 67 degrees divided by the hypotenuse

$z=(13)sin(67\°)=12\ units$
