Answer:

Answer:

Mary's ticket was less than the original price by 12 percent

Step-by-step explanation:

1. Let's calculate the 20% discount price Mary received:

75 - 0.2 * 75 = 75 - 15 = $ 60

The discounted price is $ 60

2. Let's calculate the 10% service fee to the discounted price:

60 + 0.1 * 60 = 60 + 6 = $ 66

The price including the service fee is $ 66

3. Finally, let's calculate the less percentage than the original price:

Let's use the Direct Rule of Three, this way:

Price Percentage

75 100

66 x

**************************

75x = 66 * 100

75x = 6,600

x = 6,600/75

x = 88

Less percentage = 100 - 88 = 12%

Mary ticket was less than the original price by 12 percent

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!

How many favorable outcomes will there be for spinning blue at least once? <br> (I NEED HELP PLEASE)

Westkost [7]

Answer:

It depends on the spinner and how many of each color spaces are on it.

Step-by-step explanation:

A favorable outcome means an outcome that matches your criteria.

Example: You spin a spinner with 10 spaces. 3 blue, 2 red, 3 green, 2 yellow.

If you spin the spinner once, there are 3 favorable outcomes (remember a favorable outcome means landing on blue in this case).

Spinning the spinner twice would lead to at least 100 outcomes, 9 of which are favorable.
