What are sides of a pentagon with different sides ?

If the sides of a pentagon are not equal in measure, it is termed as an irregular pentagon. In this case, the perimeter of the pentagon can be calculated by using the basic formula, Perimeter = sum of its sides.

Given,

side 1 = 2x

side 2 = 10

side 3 = x+2

side 4 = 11

side 5 = 3x-2

Sum of all the sides of the pentagon,

2x+10+(x+2)+11+(3x-2)=63

2x+10+x+2+11+3x-2=63

6x+21=63

6x=63-21

6x=42

x=42/6

x=7

Answer:

3.4

Step-by-step explanation:

Equation:

12x = 40.8

Isolate the variable:

x = 40.8/12

x = 3.4

Answer:

x = 3.4

Step-by-step explanation:

12x = 40.8

40.8 / 12 = 3.4

x = 3.4

Answer:

Explained below.

Step-by-step explanation:

The correlation coefficient for the portfolio with each of the other stocks is 0.40.

This correlation coefficient is less than 1. This implies that the portfolio’s assets are weakly correlated with each other.  

The portfolio profits from modification. Randomly selected stocks are added to the portfolio.  

The correlation coefficient of these stocks with the other stocks in the portfolio is about 0.30.  

Therefore adding these randomly selected stocks will decrease the portfolio’s standard deviation.  

Company-specific risk in portfolio can be reduced by this diversification but systematic or market risk can’t be eliminated. Thus the risk will (σ) decrease slowly until σp reaches to the average standard deviation of returns on the market i.e. about 20 %.

Answer:

g = 1.6t

Step-by-step explanation:

Here, we want to select the equation that shows the correct relationship between g and t

We are told that after 6 seconds, we have 9.6 gallons of water

So the amount per second will be 9.6/6 = 1.6 gallons per second

So the relationship between the two will be

g = 1.6t

Where t is the time and g is the gallons

The error is he set the factored expressions equal to each other(option3).

In a graph, the point where the line or curve crosses the axis is called the intercept. If a point crosses the x-axis it is x-intercepts. If a point crosses y-axis it is y-intercepts.

For finding x-intercepts of the given function,

First we have to factorize the given equation and then find the x values .

In [tex]f(x)=x^{2} +4x+3[/tex]

When we factorize we get , (x+3) and (x+1)

i.e., x+3=0⇒x=-3, x+1=0⇒x=-1.

That is x- intercept is -1 and -3.

Instead of this step Mathieu equated x+3=x+1.

This makes an error.

Hence, the error is he set the factored expressions equal to each other.

Answer:

29 and 31

Step-by-step explanation:

Let

x = the first odd number

x + 2 = the second odd number

seven times the smaller number is 17 more than six times the larger

7*x = 17 + 6(x + 2)

7x = 17 + 6x + 12

Collect like terms

7x - 6x = 29

x = 29

x + 2 = 29 + 2

= 31

Check:

7*x = 17 + 6(x + 2)

7*29 = 17 + 6(29 + 2)

203 = 17 + 6(31)

203 = 17 + 186

203 = 203

Therefore, the two consecutive odd numbers are 29 and 31

Answer:

78 Degrees

Step-by-step explanation:

Two supplementary angles:

4x + 2 + 3x + 3 = 180

Combine like terms:

7x + 5 = 180

Simplify

7x = 175

x = 25

(25)3 + 3 = 75 + 3 = 78

Angle DCB is 78 degrees

Answer:

78 Degrees

Step-by-step explanation:

Two supplementary angles:  (GIven)

4x + 2 + 3x + 3 = 180

Combine like terms:

7x + 5 = 180

Simplify

7x = 175

x = 25

(25)3 + 3 = 75 + 3 = 78

So,

Angle DCB is 78 degrees.

Answer:

m∠BCD = 90°

∠BCD is a right angle

Step-by-step explanation:

If a ray bisects an angle, that means it divides the angle into two equal parts in measure

∵ Ray CE bisects ∠BCD

→ Means divide it into two angles BCE and ECD which equal in measures

∴ m∠BCE = m∠ECD = [tex]\frac{1}{2}[/tex] m∠BCD

∵ m∠BCE = 3x - 6

∵ m∠ECD = 2x + 11

→ Equate them to find x

∴ 3x - 6 = 2x + 11

→ Add 6 to both sides

∵ 3x - 6 + 6 = 2x + 11 + 6

∴ 3x = 2x + 17

→ Subtract 2x from both sides

∵ 3x - 2x = 2x - 2x + 17

∴ x = 17

∵ m∠BCE =  [tex]\frac{1}{2}[/tex] m∠BCD

→ Substitute x in the measure of ∠BCE to find it, then use it to

   find m∠BCD

∵ m∠BCE = 3(17) - 6 = 51 - 6

∴  m∠BCE = 45°

∵ 45 = [tex]\frac{1}{2}[/tex] m∠BCD

→ Multiply both sides by 2

∴ 90 = m∠BCD

∴ m∠BCD = 90°

→ The measure of the acute angle is less than 90°, the measure of

   the obtuse angle is greater than 90°, and the measure of the

   right angle is 90°

∴ ∠BCD is a right angle
