Answer:

? = 152-x

Step-by-step explanation:

The sum of the angles of a triangle equal 180

A+B+C = 180

28 + ? +x = 180

? = 180 - 28 - x

? = 152-x

Answer:

? = ( 152 - x )°

Step-by-step explanation:

We know that sum of all angles of triangle is 180°.

28° + x° + ? = 180°

subtract 28° from each side

28° - 28° + x + ? = 180° - 28°

x + ? = 152

Now, subtract x from each side

x - x + ? = 152 - x

? = 152 - x

Scor Question Help 4.D.49 You can afford monthly payments of $500. If current mortgage rates are 2.83% for a 15-year fixed rate

lakkis [162]

Answer:

No down payment = $73 267; 10 % down payment = $81 408

Step-by-step explanation:

1. With no down payment

The formula for a maximum affordable loan (A) is

A = (P/i)[1 − (1 + i)^-N]

where

P = the amount of each equal payment

i = the interest rate per period

N = the total number of payments

Data:

P = 500

APR = 2.83 % = 0.0283

t = 15 yr

Calculations:

You are making monthly payments, so

i = 0.0283/12 = 0.002 358 333

The term of the loan is 15 yr, so

N = 15 × 12 = 180

A = (500/0.002 3583)[1 − (1 + 0.002 3583)^-180]

= 212 014(1 - 1.002 3583^-180)

= 212 014(1 - 0.654 424)

= 212 014 × 0.345 576

= 73 267

You can afford to spend $73 267 on a home.

2. With a 10 % down payment

Without down payment, loan = 73 267

With 10 % down payment, you pay 0.90 × new loan

0.90 × new loan = 73 267

New loan = 73267/0.90 = 81 408

With a 10 % down payment, you can afford to borrow $81 408 .

Here’s how it works:

Purchase price = $81 408

Less 10 % down = <u> -8 141 </u>

Loan = $73 267

And that's just what you can afford.

A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden.

Cerrena [4.2K]

Answer:

96 feet

Step-by-step explanation:

Given : A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden.

To Find: How much fencing will he need? Round to the nearest foot.

Solution:

Formula of diagonal of square = $\sqrt{2}a$

Where a is the side of the square.

Since we are given the diagonal length of square garden = 34 ft.

So, $34=\sqrt{2}a$

$\frac{34}{\sqrt{2}}=a$

$24.04=a$

Thus the side of the square garden is 24.04 ft.

Now we are supposed to find how much fencing is required

So, we are supposed to find the perimeter of square.

Perimeter of square = $4 \times side$

= $4 \times 24.04$

= $96.16$

Thus he need 96.16 ≈ 96 feet fencing .
