Helpp I’m confused pleasee!

Answer:

Circumference = 39.6 cm

We know:

Circumference of a circle = 2πr

⇒39.6 =2×

22

7

×r⇒

39.6×7

2×22

=r⇒r=6.3 cm

Also,

Area of the circle = πr2

=

22

Answer:

[tex]Q = \frac{k}{14}[/tex]

Step-by-step explanation:

Given

k and 14

Required

Determine the quotient

Quotient implies that we divide k by 14.

So, the quotient (Q) of k and 14 is:

[tex]Q = \frac{k}{14}[/tex]

Answer:

Quadrilateral just means "four sides"

(quad means four, lateral means side).

A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.

Step-by-step explanation:

propertiesA quadrilateral has:

four sides (edges)

four vertices (corners)

interior angles that add to 360 degrees:

Quadrilateral Angles

Try drawing a quadrilateral, and measure the angles. They should add to 360°

Types of Quadrilaterals

There are special types of quadrilateral:

Types of Quadrilateral

Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. See below for more details.

Let us look at each type in turn:

The Rectangle

Rectangle

the little squares in each corner mean "right angle"

A rectangle is a four-sided shape where every angle is a right angle (90°).

Also opposite sides are parallel and of equal length.

The Square

Square

the little squares in each corner mean "right angle"

A square has equal sides (marked "s") and every angle is a right angle (90°)

Also opposite sides are parallel.

A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).

The Rhombus

Rhombus

A rhombus is a four-sided shape where all sides have equal length (marked "s").

Also opposite sides are parallel and opposite angles are equal.

Rhombus Diagonals

Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.

A rhombus is sometimes called a rhomb or a diamond.

The Parallelogram

Parallelogram

A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same).

NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!

Example:

Square

A parallelogram with:

all sides equal and

angles "A" and "B" as right angles

is a square!

The Trapezoid (UK: Trapezium)

Trapezoid (or Trapezium) Trapezoid (or Trapezium)

Trapezoid

Isosceles Trapezoid

A trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel.

And a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides:

Trapezoid Trapezium

In the US: a pair of parallel sides NO parallel sides

In the UK: NO parallel sides a pair of parallel sides

(the US and UK definitions are swapped over!)

An Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles.

The Kite

The Kite

Hey, it looks like a kite (usually).

It has two pairs of sides:

Each pair is made of two equal-length sides that join up.

Also:

the angles where the two pairs meet are equal.

the diagonals, shown as dashed lines above, meet at a right angle.

one of the diagonals bisects (cuts equally in half) the other.

... and that's it for the special quadrilaterals.

Irregular Quadrilaterals

The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.

The "Family Tree" Chart

Quadrilateral definitions are inclusive.

Example: a square is also a rectangle.

So we include a square in the definition of a rectangle.

(We don't say "Having all 90° angles makes it a rectangle except when all sides are equal then it is a square.")

This may seem odd, as in daily life we think of a square as not being a rectangle ... but in mathematics it is.

Using the chart below we can answer such questions as:

Is a Square a type of Rectangle? (Yes)

Is a Rectangle a type of Kite? (No)

Quadrilateral Classification

Complex Quadrilaterals

Oh Yes! when two sides cross over, we call it a "Complex" or "Self-Intersecting" quadrilateral, like these:

Complex Quadrilaterals

They still have 4 sides, but two sides cross over.

Polygon

A quadrilateral is a polygon. In fact it is a 4-sided polygon, just like a triangle is a 3-sided polygon, a pentagon is a 5-sided polygon, and so on.

Play with Them

Now that you know the different types, you can play with the Interactive Quadrilaterals.

Other Names

A quadrilateral can sometimes be called:

a Quadrangle ("four angles"), so it sounds like "triangle"

a Tetragon ("four polygon"), so it sounds like "pentagon", "hexagon", etc.

Answer: D+<B=180

x+24+x+10=180sum of opposite angle of quadrilateral is 180

2x=180-34

x=146/2=73

again

<A+<C=180sum of opposite angle of quadrilateral is 180

x+15+<C=180

73+15+<C=180

<C=180-88=92° is your answer

Answer:

Passing practice takes less time

Step-by-step explanation:

Given:

Taken time for passing practice = 3/4 hour

Taken time for shooting practice = 4/5 hour

Find:

which practice take less time

Computation:

Change into minutes

Taken time for passing practice = [3/4]60 = 45 minutes

Taken time for shooting practice = [4/5]60 = 48 minutes

Passing practice takes less time

Answer:

6x + 7 = 8

Step-by-step explanation:

Let x represent the unknown number.

Translating the word problem into an algebraic expression, we have;

6x + 7 = 8

To find the value of x;

6x = 8 - 7

6x = 1

x = 1/6

Can i get brainliest?

Hi there!

[tex]\large\boxed{x = 18}[/tex]

3x + 2x + 90 = 180

Begin by combining like terms:

5x + 90 = 180

Subtract 90 from both sides to isolate for x:

5x + 90 - 90 = 180 - 90

5x = 90

Divide both sides by 5 to further isolate:

5x/5 = 90/5

x = 18.

Answer:

To calculate the overhead rate, divide the indirect costs by the direct costs and multiply by 100. If your overhead rate is 20%, it means the business spends 20% of its revenue on producing a good or providing services. A lower overhead rate indicates efficiency and more profits.
