Answer: The coast of the jenes is 37

Answer 2

Answer: cost of jeans is 65 bc they only bought one pair. the amount won’t change because it’s one pair (constant amount). 35x is the cost of the shirts bc it says they bought multiple, so the overall cost can change, depending on how many shirts.

jeans = 65
shirts = 35x

J. ( 4, 1)
K. ( 5, 0)

Answers

Answer: The required point that could also be a vertex of the square is K(5, 0).

Step-by-step explanation: Given that the sides of a square are 3 cm long and one vertex of the square is at (2,0) on a square coordinate grid marked in centimeter units.

We are to select the co-ordinates of the point that could also be a vertex of the square.

To be a vertex of the given square, the distance between the point and the vertex at (2, 0) must be 3 cm.

Now, we will be suing the distance formula to calculate the lengths of the segment from the point to the vertex (2, 0).

If the point is F(-4, 0), then the length of the line segment will be

$\ell=√((-4-2)^2+(0-0)^2)=√(6^2+0^2)=√(6^2)=6~\textup{cm}\neq 3~\textup{cm}.$

If the point is G(0, 1), then the length of the line segment will be

$\ell=√((0-2)^2+(1-0)^2)=√(2^2+1^2)=√(4+1)=\sqrt5~\textup{cm}\neq 3~\textup{cm}.$

If the point is H(1, -1), then the length of the line segment will be

$\ell=√((1-2)^2+(-1-0)^2)=√(1^2+1^2)=√(1+1)=\sqrt2~\textup{cm}\neq 3~\textup{cm}.$

If the point is J(4, 1), then the length of the line segment will be

$\ell=√((4-2)^2+(1-0)^2)=√(2^2+1^2)=√(4+1)=\sqrt5~\textup{cm}\neq 3~\textup{cm}.$

If the point is K(5, 0), then the length of the line segment will be

$\ell=√((5-2)^2+(0-0)^2)=√(3^2+0^2)=√(3^2)=3~\textup{cm}.$

Thus, the required point that could also be a vertex of the square is K(5, 0).

Th vertices of a sandbox are p(12, 14), Q(12, 17), R (16, 17) and S (16, 14).the coordinates are measured in feet . What is the perimeter of the sandbox ?

Answers

Answer:

The perimeter of the sandbox is 14 feet

Step-by-step explanation:

To find the perimeter of the sandbox, we will find the distance between the points using the distance formula and then add them together

p(12, 14), Q(12, 17), R (16, 17) and S (16, 14)

Distance formula;

D = √ ( $x_(2)$ - $x_(1)$ )² + ( $y_(2)$ - $y_(1)$ )²

p(12, 14) Q(12, 17)

|PQ| = √ ( $x_(2)$ - $x_(1)$ )² + ( $y_(2)$ - $y_(1)$ )²

= √(12-12)² + (17-14)²

= √0² + (-3)²

=√9

|PQ| = 3

Q(12, 17) R (16, 17)

|QR| = √ ( $x_(2)$ - $x_(1)$ )² + ( $y_(2)$ - $y_(1)$ )²

=√( 17 - 17)² + (16 - 12)²

=√0² + 4²

=√16

= 4

|QR| = 4

R (16, 17) S (16, 14)

|RS| = √ ( $x_(2)$ - $x_(1)$ )² + ( $y_(2)$ - $y_(1)$ )²

=√(16-16)² + (14 -17)²

=√0² + (-3)²

=√9

|RS| = 3

S (16, 14) p(12, 14)

|SP| = √ ( $x_(2)$ - $x_(1)$ )² + ( $y_(2)$ - $y_(1)$ )²

=√ (14 - 14)² + (12 - 16)²

=√0² + (-4)²

=√16

|SP| = 4

Perimeter = |PQ| + |QR| + |RS| + |SP|

= 3 + 4 + 3 + 4

=14

Since the coordinates are measured in feet, perimeter= 14 feet

Therefore the perimeter of the sandbox is 14 feet.

12,14 to 12,17 is a rise of 3 (14 to 17).
12,14 to 16,14 is a move to the right of 4 (12 to 16)

That means the dimensions of the sandbox are 3ft by 4ft and the perimeter is 2(l+w) or in this case 2 (3+4) or 14 ft

A store has a sale on books. The price is $17.55 for one book, $16.70 each for 2 books, $15.85 each for 3 books, and $15 each for 4 books. If this pattern continues, how much per book will it cost to buy 7 books

Answers

The cost for each book will be $\boxed{\$ 12.45}$ if the person buy 7 books.

Further explanation:

The arithmetic sequence can be expressed as follows,

${a_1}, {a_2}, {a_3}$ ......

Here, $a{\text{ or }}{a_1}$ represents the first term, ${a_2}$ represents the second term, and so on.

The common difference “d” can be obtained as follows,

$\boxed{d = {a_2} - {a_1}}$

The nth term can be obtained as follows,

$\boxed{{a_n} = a + \left( {n - 1} \right)d}$

Explanation:

The cost of a book is $\$ 17.55.$

The cost of a book is $\$ 16.70$ if the person buys 2 books.

The cost of a book is $\$ 15.85$ if the person buys 3 books.

The cost of a book is $\$ 15.00$ if the person buys 4 books.

The sequence is $\$ 17.55, \$ 16.70, \$ 15.85, \$ 15.00.$

The first term is $\$ 17.55,$ the second term is $\$ 16.70.$

The common difference “d” can be obtained as follows,

$\begin{aligned}d&={a_2} - {a_1}\n&=16.70 - 17.55\n&=- 0.85\n\end{aligned}$

The cost for each book if the person buys 7 books can be obtained as follows,

$\begin{aligned}{a_6}&= 17.55 + \left( {7 - 1} \right)\left( { - 0.85} \right)\n&= 17.55 + 6\left({ - 0.85} \right)\n&= 17.55 - 5.1\n&=\$12.45\n\end{aligned}$

The cost for each book will be $\boxed{\$ 12.45}$ if the person buy 7 books.
