Answer:

  24√3 square units

Step-by-step explanation:

The side length of a regular hexagon is 2/√3 times the length of the apothem. For an apothem of 2√3, the side length is ...

  s = (2/√3)(2√3) = 4

The perimeter P of the hexagon is 6 times the side length, so is 6×4 = 24.

The area is given by ...

  A = 1/2Pa

where P is the perimeter and 'a' is the apothem.

  A = 1/2(24)(2√3) = 24√3

The area of the hexagon is 24√3 square units.

_____

A hexagon can be divided into 6 congruent equilateral triangles. The apothem will be the altitude of one of those, so will divide the triangle into two triangles with angles 30°, 60°, and 90°. The ratios of the side lengths of such a triangle is something you might want to remember: 1 : √3 : 2. The altitude corresponds to the "√3" side, and the side length of the equilateral triangle corresponds to the "2" side. That is, we have the proportion ...

  apothem : hexagon side = √3 : 2

Multiplying by 2 gives the actual values in the hexagon of this problem:

  apothem : hexagon side = 2√3 : 4

Answer:

x = 3 (I think)

Step-by-step explanation:

14x - 13 = 8x + 5 (I'm assuming the two expressions are equal)

6x - 13 = 5

6x = 18

x = 3

The simplified value of x from the equation is x = 3

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

( 14x - 13 ) = ( 8x + 5 )

Subtracting 8x on both sides , we get

( 14x - 8x ) - 13 = 5

6x - 13 = 5

Adding 13 on both sides , we get

6x = 18

Divide by 6 on both sides , we get

x = 18/6

x = 3

Hence , the equation is solved and x = 3

Answer: Mason made $185.00

Step-by-step explanation:

For the first 10 suits he made $12.50 each suit, then he made $20 for the additional 3.  (Just ignore the "suits part ._.)

250*.05=12.50

250*.08=20

12.50*10=125

3*20=60

125+60=185.

Answer:

1. 21+5f = 61

2. 18+5n=50.50

3. 40+30s=220

Step-by-step explanation:

1. SUM of 21 and 5 TIMES a number f is 61

From that sentence, sum means addition and times is multiplication, so:

21+5f = 61

2. Let's identify the given:

Monthly fee: 18

Cost of each call: 5

Variable that symbolizes the call: n

Total cost this month: 50.50

Thus, 18+5n=50.50

3. Identify the given:

Charge of tutor: 40

Charge of tutor every student: 30

Variable representing the number of students: s

Total charge: 220

Thus, 40+30s=220

Answer:

I think its 229

if you take how many yellow marbles he got out of 7 it would be 3/7 and then I divided 400 by 7 and got 57. something so I multiplied 3 times 57 and got 171. So if you take 400-171 you get 229

Answer:

3 grams

Step-by-step explanation:

We are going to take the mass of a bunch of little strips below the triangle "roof." To do this, we must figure out what formula for the mass we'll use, in this case, we'll use:

Mass of strip = denisty * area = (1+x)*y*deltax grams

now, because the "roof" of the triangle contains two different integrals (it completely changes direction), we will use TWO integrals!

**pretend ∈ is the sum symbol

Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral -1 to 0 of (1+x)*3*(x+1) = 3 * integral -1 to 0 of (x^2 + 2x + 1) = 3 *  1/3 = 1

Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral 0 to 1 of (1+x)*3*(-x+1) = 3 * integral 0 to 1 of (-x^2 + 1) = 3 * 2/3 = 2

Total mass = mass left + mass right = 1 + 2 = 3 grams

The value of x is given from the inequality equation 0 < x < 27

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

From the parallelogram , AB ≈ BC

So , The ( ∠ CBD ) > ( ∠ ABD )

Substituting the values in the equation , we get

( 2x ) < 54°

Divide by 2 on both sides of the equation , we get

x < 54/2

x < 27°

And , ∠ ABD cannot be negative or zero ,

So , 2x < 0

Divide by 2 on both sides of the equation , we get

x < 0

Hence , the inequality equation is 0 < x < 27

Answer:

3.60

Step-by-step explanation:

The amount of tip will be $3.6.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the restaurant bill for lunch is $24 and the tip given to the waiter is 15% of the total amount.

The total amount will be calculated as:-

Amount of tip = 24 x 15%

Amount of tip = 24 x 0.15

Amount of tip = $3.6

Hence, the tip amount will be $3.6
