​

Answer:

A=13.47 in.

P=14.68 in.

Step-by-step explanation:

First, we have to figure out the sides of square ABCD. The diagonal forms the hypotenuse of a right equilateral triangle.

a²+a²=6²

2a²=36

a²=18

a=√18

a=4.24

Half of 4.24 would be the distance From each corner of ABCD to the neighboring midpoints.  (2.12)

2.12²+2.12²=c²

4.49+4.49=c²

13.48=c²

√13.48=c

3.67=c

Now that we know each side of the shaded square, we can get the area and perimeter.

A=3.67x3.67=13.47

P=3.67x4=14.68

Answer:

Common-size percent for cash = 5.73 % (Approx.)

Step-by-step explanation:

Given:

Total cash = $26,200

Total assets = $457,000

Total equity = $156,630

Find:

Common-size percent for cash

Computation:

Common-size percent for cash = [Total cash/Total assets]100

Common-size percent for cash = [26,200/457,000]100

Common-size percent for cash = 5.73 % (Approx.)

Answer:

(x + 5)

Step-by-step explanation:

(x² - 25) ÷ (x-5)

=(x² - 5²) ÷ (x-5)

Using the formula a² - b² = (a + b)(a - b) you get

= (x + 5)(x - 5) ÷ (x - 5)

With division you can cut both (x - 5)

So the answer is (x + 5)

Answer:

435 ft

Step-by-step explanation:

Reference angle = <P = 49° (angle of elevation)

Opposite side = 500 ft

Adjacent side = d = ?

Apply trigonometric function, TOA.

This:

Tan P = opp/adj

Tan 49 = 500/d

d × Tan 49 = 500

d = 500/Tan 49

d = 434.643369 ≈ 435 ft (to the nearest foot)

Answer:

This expression has no roots.

Step-by-step explanation:

Using the discriminant: b² - 4ac, we get:

2² - 4 × 3 × 1

= 4 - 12

= -8

So this equation has no real solutions.  Let's prove that by trying to solve for x:

3x² + 2x + 1 = 0

9x² + 6x + 3 = 0

9x² + 6x + 1 = -2

(3x + 1)² = -2

3x + 1 = i√2

3x = -1 ± i√2

x = (-1 ± i√2) / 3

The only solutions available then are indeed complex.

This expression has no roots. the discriminant of the equation is -8.

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Using the discriminant: b² - 4ac, we get:

2² - 4 × 3 × 1

= 4 - 12

= -8

So this equation has no real solutions.  Let's prove that by trying to solve for x:

3x² + 2x + 1 = 0

9x² + 6x + 3 = 0

9x² + 6x + 1 = -2

(3x + 1)² = -2

3x + 1 = i√2

3x = -1 ± i√2

x = (-1 ± i√2) / 3

Answer:

The couch costs $678 and $339 for the coffee.

Step-by-step explanation:

In total you spent $1017 and it was used in 3 portions, 2 for the couch, and 1 for the coffee. First divide it and find out how much each portion costs. In this case (1017 divided by 3) the answer will be 339. Now since you spent 2 of the 3 portions on the couch multiply one portion by 2. Then you get 678 for 2 portions, hence telling us that the couch costed, $678. With the remaining one portion of 339, you already know coffee costs $339.

Answer:

M, B, A, T, K are the points of the statement: x<y

Step-by-step explanation:

oh dis is easy peasy lemony squeezy yes big bran time now onto the question :D

So the X has to be smaller than the Y. right?

ok, let's go with point M first shall we?

Coordinates are: 0, 6

is X smaller than Y? yes. yes indeed it is...

----------------------------------------------------------

Point N:

Coordinates are: 3, 3

Is X smaller than Y? no. No they are not.

Hope this helps!

The boat is x=376 foot away from the light house.

A person is watching a boat from the top of a lighthouse. The angle of depression from the person to the boat is 28°. The lighthouse is 200 feet tall.

Trigonometry is defined as the study of angles.

Let the boat is x distance away from the lighthouse

assume a right-angle triangle ABC with AB =perpendicular=200, BC = base=X,  Angle CAB = 28°(angle of depression means the angle from the boat to the top of lighthouse is also 28°)

tan28 = 200/X
X = 200/tan28
X = 376 foots

Thus, The boat is x=376 foot away from the lighthouse.

Answer:

1/5

Step-by-step explanation:

Chance is also referred to as probability

probability = Number of event/Total samples space

If there are 6 black socks,8 white socks,2 red socks, and 4 blue socks in a drawer, the total number of socks will be the sample space

Sample space = 6 + 8 + 2 + 4

Sample space = 20socks

Total number of blue socks is the event

Number of event = 4 blue socks

Chance that the socks is blue = n(E)/n(S)

Chance that the socks is blue = 4/20

Chance that the socks is blue = 1/5
