Answer:

x=7

Step-by-step explanation:

The two angles are alternate interior angles.  If they lines are parallel, then the angles are equal.

7x-7 = 4x+14

Subtract 4x from each side

7x-4x -7 = 4x-4x+14

3x-7 = 14

Add 7 to each side

3x-7+7 = 14+7

3x=21

Divide by 3

3x/3 =21/3

x=7

Each of six jars contains the same number of candies. Alice moves half of the candies from the first jar to the second jar. Then
Crazy boy [7]

Answer:

The number of candies in the sixth jar is 42.

Step-by-step explanation:

Assume that there are <em>x</em> number of candies in each of the six jars.

⇒ After Alice moves half of the candies from the first jar to the second jar, the number of candies in the second jar is:

\text{Number of candies in the 2nd jar}=x+\fracx}{2}=\frac{3}{2}x

⇒ After Boris moves half of the candies from the second jar to the third jar, the number of candies in the third jar is:

\text{Number of candies in the 3rd jar}=x+\frac{3x}{4}=\frac{7}{4}x

⇒ After Clara moves half of the candies from the third jar to the fourth jar, the number of candies in the fourth jar is:

\text{Number of candies in the 4th jar}=x+\frac{7x}{4}=\frac{15}{8}x

⇒ After Dara moves half of the candies from the fourth jar to the fifth jar, the number of candies in the fifth jar is:

\text{Number of candies in the 5th jar}=x+\frac{15x}{16}=\frac{31}{16}x

⇒ After Ed moves half of the candies from the fifth jar to the sixth jar, the number of candies in the sixth jar is:

\text{Number of candies in the 6th jar}=x+\frac{31x}{32}=\frac{63}{32}x

Now, it is provided that at the end, 30 candies are in the fourth jar.

Compute the value of <em>x</em> as follows:

\text{Number of candies in the 4th jar}=40\\\\\frac{15}{8}x=40\\\\x=\frac{40\times 8}{15}\\\\x=\frac{64}{3}

Compute the number of candies in the sixth jar as follows:

\text{Number of candies in the 6th jar}=\frac{63}{32}x\\

                                                    =\frac{63}{32}\times\frac{64}{3}\\\\=21\times2\\\\=42

Thus, the number of candies in the sixth jar is 42.

You are told today that you’ll inherit a castle from your uncle in 5 years. You’ll need to pay a property tax of $500,000 on the
lakkis [162]

Answer:

The amount set aside today for property taxes is $3,449,563.

Step-by-step explanation:

Amount required for property taxes is given as

Amount required = \frac{Property\ taxes\ in\ year\ 6}{(Interest\ rate - Growth\ rate)}

where Porperty tax  = $500,000

interest tax = 10%

growth rate  =  1%

                           = \frac{500,000}{(10\% - 1\%)}

                           = 5,555,556

Thus, the amount required after 5 years property taxes is $5,555,556.

So, Present value

Present value = \frac{Amount\ required\ after\ 5\ years}{(1 + Rate)^{Number\ of\ years}}

                    = \frac{5,555,556}{(1 + 0.10)^5}

                    = \frac{5,555,556}{1.6105}

                    = $3,449,563

Therefore , the amount set aside today for property taxes is $3,449,563.
