FIRST CORRECT ANSWER I WILL GIVE BRANLIEST TO!!

Answer:

19.92

Step-by-step explanation:

To find the length of AC we need to use the Pythagorean theorem: a^2 + b^2 = c^2

a = 6 b = 19

a^2 = 36

b^2 = 361

36 + 361 = 397

c^2 = 397

to find c we take the square root of 397

[tex]\sqrt{397} = 19.9248588452[/tex]

C) A quadrilateral with four congruent sides and four right angles is a square.

The  P ↔ Q represents A quadrilateral with four congruent sides and four right angles is a square.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

Given:

If a quadrilateral has four congruent angles, then it's a rectangle.

the statement cannot be true because the same property also carried by Square.

If a quadrilateral has four congruent sides, then it's either a square or a rhombus but reverse is not possible.

A quadrilateral with four congruent sides and four right angles is a square.

The statement is perfectly true because the reverse is also possible.

The value of angle y is equal to 60°

Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. They lie on the inner side of the parallel lines but on the opposite sides of the transversal.

The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .

According to the question

AB is parallel to CD

and the line intersect AB and CD is transversal line

Therefore ,

∠y , 60° are Alternate Interior Angles  .

Now ,

According to the Alternate Interior Angles Theorem

When two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .  

Therefore,  

y = 60°

Hence. The value of angle y is equal to 60°  .

Answer:

D. 1

Step-by-step explanation:

Answer:

D.441

Step-by-step explanation:

All sides of a square are equal. Due to this, the perimeter can be expressed as 4 times the side of the square. Let x be the side of a square.

Then we have:

4x = 84

x = 21

The area of a square is written as x^2, as x is both the length and the width.

So your answer will be:

(21)^2 = 441

The area of the garden is  441 sq ft

A square is a quadrilateral with four equal sides.

Characteristics of a square includes:

• The diagonals bisect each other at 90°.

• Opposite sides parallel and of equal length

• The four angles of a square are equal.

Perimeter of a square =4 x length

84 = 4 x length

divide both sides of the equation by 4

84/4 = length

length = 21 feet

Area of a square = length²

21² =  441 sq ft

Answer:

x = 3

Step-by-step explanation:

Rectangle = length*width = 3(x+12) = 3x+36

Triangle = length*width/2 = 2x*5/2 = 5x

Since the rectangle is 3 times the triangle, thjat gives us:

3x+36 = 3(5x) -> 3x + 36 = 15x

Isolate x and solve:

36 = 12x

x = 3

Answer:

Option A. 95x + 133y square feet.

Step-by-step explanation:

Area of a rectangular room = Length × Width

Length of the room = Length of carpeted portion + Length of the tiled portion

= (5x + 7y) feet

Width of the living room = 19 feet

Area of the living room = (5x + 7y) × 19

                                      = 95x + 133y Square feet [By distributive property]

Therefore, expression for the total area of the living room is option (A).

Answer:

EVERYONE IT IS 3/4 lol

Step-by-step explanation:

The difference of the expression (-3 + 1/2) - (-4 + 1/4) is 3/4.

Additive inverse in simple terms is meant to add a number with it's opposite sign to get the result as zero.

Mathematically for any number 'a', a + (-a) = 0 implies that -a is the additive inverse of 'a'.

The given expression is, (-3 + 1/2) - (-4 + 1/4).

(-3 + 1/2) - (-4 + 1/4) = [(-3 × 2 + 1) / 2] - [(-4 × 4 + 1) / 4]

                               = (-7/2) - (-17/4)

The additive inverse of (-7/2) is (+7/2).

Adding and subtracting the additive inverse (+7/2),

(-3 + 1/2) - (-4 + 1/4) = (-7/2) - (-17/4) + (7/2) - (7/2)

                               =  (-7/2) + (17/4) + (7/2) - (7/2)

                               = [(-7/2) - (7/2)] + [(17/4) + (7/2)]

                               = (-14/2) + (31/4)

                               = (-28/4) + (31/4)

                               = 3/4

Hence the difference of the expression given is 3/4.

Answer:

$1478.73

Step-by-step explanation:

Use the compound amount factor and assume compounding once per year.  Then:

A = $900(1 + 0.18)^3

   =  $1478.73 due after three years.

Answer:

= $1478.73 or = $1478.72

Step-by-step explanation:

Credit companies charge daily but you only mention yearly question so i will show you yearly and monthly and daily as 3 separate methods.

For years

we use the expression a x {(+1) + b} ^t  = 900 x 1.18^3

For months

we use the expressions a x {( +1) +b ^t * 12

We keep to yearly interest

And prove 900 x 1.18^3 = 1478.7288

= $1478.73

Generally, credit companies round down to $1478.72

We work out a yearly rate = 18% interest and divide amount borrowed by 18%

900/18 = 50

then whatever is paid we minus this from the $900 = 900 x 50 = 45,000

50 x 365 = 18,250 owed if no payments were met if agreed to pay monthly but before end of the 3 year contract = meaning if paid at end of month 12- before start of month 13 the 360th day.

Answer:

5t² - 16t + h =0

Step-by-step explanation:

During upward projection the final velocity is zero, and the gravitational acceleration is -10 m/s² (against the gravity).

Therefore; using the equation;

S = 1/2gt² + ut

Where s is the height h, g is gravitational acceleration, and t is the time and u is the initial velocity u, is 16 ft/s.

Thus; h= 1/2(-10)t² + 16t

We get; h = -5t² + 16t

Therefore; the quadratic equation is 5t² - 16t + h =0

Answer:

f(x) can be odd or even.

Step-by-step explanation:

The following information is missing in the question:

Suppose f(x) is a function such that if p < q, f(p) < f(q). Which statement best describes f(x)?

With the information given it is not possible to determine if the function is even or odd.

Even functions: f(-x) = f(x). For examle, (-2)² = 2², then x² is even

Odd functions: f(-x) = -f(x). For examle, (-2)³ = -(2³), then x³ is odd

In both cases, x² and x³, if p < q, f(p) < f(q). For example, 1² < 2², and 1³ < 2³
