A rectangle has a width represented by the expression 2y and a length represented by 12y - 5. which expression represents the ar
docker41 [41]

Correct option is B. Area of rectangle is 24y^{2} - 10 y

We know that area of rectangle = Length × Width

We are given,

Length = 12y - 5

Width = 2y

So, area of rectangle = (12y - 5) × (2y)

=   (12y - 5) × (2y)

=   (12y ×  2y) - (5 × 2y)

=   24 y^{2} - 10 y

2.1 liters of coffee were equally distributed to 30 cups how many millimeters of coffee were in each cup
sattari [20]

Answer: 70 ml of coffee in each cup


Step-by-step explanation:

1 liter = 1000 ml

Amount of coffee given = <em>2.1 liters</em>

\Rightarrow <em>2.1 liters =  2.1 * 1000 = 2100 ml</em>

Total number of cups = 30

\therefore Amount of coffee in each cup = \frac{Total\ amount \ of \ coffee}{number\ of  \ cups} = \frac{2100}{30} =70

<em>∵ Amount of coffee in each cup </em>= <u>70 milliliters</u>

hoa [83]

Answer:

Theater B.

Step-by-step explanation:

Find out each theatre's percentage of seats taken.

Theater A =

100% = 60

1% = 60 ÷ 100 = 0.60

36 ÷ 0.60 = 60% of the seats taken.

Theater B =

81 + 9 = 90

100% = 90

1% = 90 ÷ 100 = 0.90

81 ÷ 0.90 = 90%

Theater C =

100% = 80

1% = 80 ÷ 100 = 0.80

80 - 12 = 68

68 ÷ 0.80 = 85%

Theater B have the greatest percentage of seats taken out of all 3.
