The value of n that satisfies the inequality is 6.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

4n − 12 < 2n + 2

For n= 6

4(6) - 12 = 12

2(6) + 2 = 14

Thus, n=6 satisfies

For n= 7

4(7) - 12 = 16

2(7) + 2 = 16

Thus, n=7 not satisfies

For n=8

4(8) - 12 = 20

2(8) + 2 = 18

Thus, n=8 not satisfies.

For n= 9

4(9) - 12 = 24

2(9) + 2 = 20

Thus, n=9 not satisfies.

The vertices of A'B'C' if A(0, 10), B(8, 6), C(4, 2) is dilated by a scale factor of 2 are;

Given that triangle ABC is dilated by a scale factor of 2, we have;

A'B' = 2 × AB

A'C' = 2 × AC

B'C' = 2 × BC

Length of AB = √((8-0)^2 + (6-10)^2) = 4•√5

Length of AC = √((4-0)^2 + (2-10)^2) = 4•√5

Length of BC = √((8-4)^2 + (6-2)^2) = 4•√2

By multiplying the given coordinates by the scale factor, we have;

A' = 2 × (0, 10) = (0, 20)

B' = 2 × (8, 6) = (16, 12)

C' = 2 × (4, 2) = (8, 4)

A'B' = √((16-0)^2 + (12-20)^2) = 8•√5

A'C' = √((8-0)^2 + (4-20)^2) = 8•√5

B'C' = √((16-8)^2 + (12-4)^2) = 8•√2

Therefore when we have;

A'(0, 20), B'(16, 12), C'(8, 4), we get;

The rate at 14% and 5% are $12, 883 and $2191 respectively.

Given that;

Invested amount = $ 15, 074 at 14% and 5%

Let rate at 14% = x

rate at 5% = y

We have rate at 9% exceeds that of 5% by $1694. 07

Hence,

0. 14x = 0. 05y + $1694. 07 ⇒ equation 1

x + y = $15, 074 ⇒ equation 2

Make 'x' the subject

x = [tex]15, 074 - y[/tex]

Substitute in equation 2

[tex]0. 14(15, 074 - y) = 0. 05y + $1694. 07[/tex]

Expand the expression

[tex]2, 110. 36 - 0. 14y = 0.05y + 1694. 07[/tex]

Collect like terms

[tex]416. 29 = 0. 19y[/tex]

Make 'y' the subject

y = [tex]\frac{416. 29}{0. 19}[/tex]

y = [tex]$2, 191[/tex]

Substitute the value in equation 2

x + y = $15, 074

x = $15, 074 - y

x = [tex]$15, 074 - 2191[/tex]

x = $12, 883

Diagonals of a parallelogram bisect each other, so

s + c = 47 equation 1

5s + 4c = 200 equation 2

Multiply equation 1 by 5

5s + 5c = 235

Subtract equation 2 from equation 3

c = 35

Subtract 35 from 47

c = 47 - 35 = 12

35 couples tickets and 12 individual tickets were sold. This is not possible since the couples tickets were sold in 2.

s + c = 47 equation 1

5s + 4c = 201 equation 2

Multiply equation 1 by 5

5s + 5c = 235

Subtract equation 2 from equation 3

c = 34

34 is divisible by 2 so the $1 belongs in the box.

Step-by-step explanation:

There are 4 areas where the pool deck is situated on:

Top, Left, Right, and Bottom of the pool.

So if the deck is 5 feet wide:

Top = (35 feet * 5 feet) = 175

Bottom = (35 feet * 5 feet) = 175

Left = (20 feet * 5 feet) = 100

Right = (20 feet * 5 feet) = 100

175 + 175 + 100 + 100 = 550 square feet

Step-by-step explanation:

Answer:

We can now take 2 as the third digit, 3 as the fourth digit, 4 as the fifth digit and finally 5 as the sixth digit. Therefore, the smallest 6-digit number having all different digits is 102345.

The smallest 6-digit multiple of 4 with all different numbers is 102,564. This number is obtained by incrementing from 100,000 until finding a divisible number with distinct digits.

A number that is the result of a given number plus another natural number is said to be a multiple of that number.

Since the smallest 6-digit number, is 100,000.

Check if this number is divisible by 4.

In this case, it is not.

Increment the number by 1 to get 100,001.

Repeat step 2. Not divisible by 4.

Increment the number by 1 to get 100,002.

Repeat step 2. Not divisible by 4.

Increment the number by 1 to get 100,003.

Repeat step 2. Not divisible by 4.

Continue this process until you find a number that is divisible by 4 and has all different digits.

After following these steps, we find that the smallest 6-digit multiple of 4 with all different numbers is 102,564.
