A stack of one hundred eighty cards is placed next to a ruler, and the height of stack is measured to be 3 8 38 inches. how thic

sp2606 [1]

Total number of cards in the stack =180

Height of stack (all cards) = 38 inches

Now, we know that the thickness of 180 cards is 38 inches,

now the thickness of one card can be obtained by dividing the total thickness by the number of cards

Thickness of 1 card = Total thickness of all cards/ total number of cards

Thickness of 1 card = 38 inches/180 = 0.211111.....inches

Each card is 0.21 inch thick (rounded to two decimals)

7. 4y(5y - 11) – 2y(3y + 10)

Kaylis [27]

Answer:

$14y^{2} -64y$

Step-by-step explanation:

Hello!

4y(5y - 11)

Distribute the 4y

4y * 5y = 20y^2

4y * -11 = -44y

Put it together

20y^2 - 44y

2y(3y + 10)

Distribute the -2y

-2y * 3y = -6y^2

-2y * 10 = -20y

Put it gether

-6y^2 - 20y

Put it all together

20y^2 - 44y - 6y^2 - 20y

Combine like terms

14y^2 - 64y

The answer is $14y^{2} -64y$

Hope this helps!
