What is the perimeter of a square if the length of one of the diagonals is 12 cm?
6v2 cm
2412 cm
48 cm
24 cm

Answers

Answer 1

Answer:

Step-by-step explanation:

Use Pythagorean theorem to find the length of the square.

Length of the square = a

a² +a² = diagonal²

2a² = 12²

2a² = 144

a² = 144 ÷ 2

a² = 72

[tex]a =\sqrt{72}\\\\ = \sqrt{2*2*2*3*3}\\\\ = 2*3\sqrt{2}\\\\a = 6\sqrt{2}\\\\\\\\Perimeter= 4a\\\\ = 4*6\sqrt{2}\\\\= 24\sqrt{2} cm[/tex]

Ross bought a TV for $1,200. She sold it with 25% loss. How much did she lose?

Answers

Ross loss $300

Step-by-step explanation:

loss % = 25%

loss = $1200 × 25 ÷100

= $30000 ÷100

= $300

selling price = cost price + loss

= $1200 + $300

= $1500

Leah is financing $340,000 to purchase a house. How much money will she save over the life of a 30-year, fixed-rate loan by buying 3 points with a rate of 6.475% instead of not buying points with a rate of 6.85%?

Answers

Answer:

$38250

Step-by-step explanation:

Given data

P= $340,000

t= 30-year,

r1= 6.475%

r2= 6.85%

For r1

A= P(1+rt)

A= 340,000(1+0.06475*30)

A= 340,000(1+1.9425)

A= 340,000*2.9425

A= $1000450

For r2

A= P(1+rt)

A= 340,000(1+0.0685*30)

A= 340,000(1+2.055)

A= 340,000*3.055

A= $1038700

The difference is '

= 1038700-1000450

Why does stock have more potential for higher returns than bonds?

Answers

Answer:

Stocks have historically delivered higher returns than bonds because there is a greater risk that, if the company fails, all of the stockholders' investment will be lost.

Step-by-step explanation:

Hope this will help

Answer:

Stocks have historically delivered higher returns than bonds because there is a greater risk that, if the company fails, all of the stockholders' investments will be lost. However, a stock's price will also rise in spite of this risk when the company performs well, and can even work in the investor's favor.

In △ABC, G is the centroid and BE = 21. Find BG and GE.

Answers

Answer:

BG = 7, GE = 14

Step-by-step explanation:

The centroid is the intercession of medians.

The centroid theorem states that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.

BE is the median and point G is 2/3 of the distance from E:

GE = 2/3BE = 2/3(21) = 14

Then BG is:

BG = BE - GE = 21 - 14 = 7

The answer is BG = 7, GE = 14

Answer:

the answer is BG=7,GE=14
