You randomly select a coin from a jar containing 30 coins: 8 pennies, 10 nickels, 7 dimes, and 5 quarters.What is the probability of:

selecting a penny?

selecting a nickel?

not selecting a dime?

selecting a dime or a quarter?

the number of goals Yolanda scores without penalties is x = 8, and the number of goals Neel scores without penalties is y = 0.

Let x be the number of goals Yolanda scores without penalties, and let y be the number of goals Neel scores without penalties.

According to the problem, Yolanda makes 6 goals and 2 penalties, so her total number of goals is:

x + 6

And her total number of points is:

(x + 6) + 2(1) = x + 8

Similarly, Neel scores 4 goals and 2 penalties, so his total number of goals is:

y + 4

And his total number of points is:

(y + 4) + 2(1) = y + 6

We know that Yolanda ends the game with 16 points, so we can write:

x + 8 = 16

Subtracting 8 from both sides, we get:

x = 8

We also know that Neel ends the game with 6 points, so we can write:

Y + 6 = 6

Subtracting 6 from both sides, we get:

y = 0

Answer:

I believe that the answer is C: 72 cm²

The correct answers are:

They consist primarily of variables.

They are often called formulas.

They often describe real-world relationships.

Explanation:

Literal equations are defined as "equations in more than 1 variable whose variables represent specific quantities."

This means that literal equations consist mostly of variables.

Since the variables represent specific quantities, this means they typically represent real-life situations.

Since they represent real-life situations, these equations are often formulas for things in the real world (such as area, volume, perimeter, circumference, etc.)
