To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $6 per hour. The chemistry c

Andrej [43]

Given:

Reservation fee = $19

Additional fee = $6 per hour

The chemistry club wants to spend at most $19 on renting the room.

To find:

The possible numbers of hours the chemistry club could rent the meeting room.

Solution:

Let n be the number of hours the chemistry club could rent the meeting room.

Reservation fee = $19

Additional fee for one hour = $6

Additional fee for n hours = $6n

Total fee = $(6n+19).

The chemistry club wants to spend at most $19 on renting the room. It means the total fee must be less than or equal to 19.

$6n+19\leq 19$

Subtract 19 from both sides.

$6n\leq 0$

Divide both sides by 6.

$n\leq 0$

Time can not be negative. So n=0.

Therefore, the possible numbers of hours the chemistry club could rent the meeting room is 0.

a square red rug has a purple square in the center. the side length of the purple square is x inches. the width of the red band

Bumek [7]

Answer:

Area of red band is $(20x + 100) inch^{2}$

Step-by-step explanation:

We know that area of square = $side^{2}$

Please refer to the attached figure, we have to calculate the area of red band.

Required area = Area of square ABCD - Area of purple square

Side of purple square = $x$

So, area of purple square = $x^{2}$

ABCD is a square with purple square at the center and there is symmetry in the figure.

So, width of red band towards both the end is 5 inches.

$\Rightarrow \text{side of }ABCD = 5 + 5 +x = (x+10) inches$

Required area = $(x+10)^{2} - x^{2}$

Using formula $a^{2} - b^{2} = (a-b)\times (a+b)$

$\Rightarrow (x+10-x)(x+10+x)\\\Rightarrow (10)(2x+10)\\\Rightarrow (20x+100)$

Hence, Area of red band is $(20x + 100) inch^{2}$
