C (Lake Depth Answer)

Step-by-step explanation:

Here we want to find the math that ends up with 0.

The stock starts with 12$, but loses 16$.

That's -4$ total, not 0.

The ion starts with 19 protons, and 18 electrons. Protons are postive charges, electrons are negative.

This leaves us with 1 proton, not 0.

The lake depth increases by 6 inches, but evaporates 6.

This leaves us back where we started, with 0.

The discount price of a book is 20% less than the
retail price. James manages to purchase the book
at 30% off the discount price at a special book
sale. What percent of the retail price did James
pay?
A) 42%
B) 48%
C) 50%
D) 56%

Answers

Answer:

Step-by-step explanation:

Let retail be $100

At 20% discount

(100-20)% * 100

0.8*100

$80

At 30% discount

(100-30)%* 80

$56

Using the percentage relationship between cost, the book was purchased at 56% of the retail price.

Let :

Retail price = r

Discount price = 0.8r

Special sale price :

30% off discount price

(1 - 0.30) × 0.8r

0.70 × 0.80r = 0.56r

Hence, the book was purchased at 56% of the retail price.

The lines below are parallel if the slope of the solid line is 4,what is the slope of the gas line?

Answers

Answer:

We conclude that the parallel lines are equal and the slope of the gas line is:

m₂ = 4

Step-by-step explanation:

We know that the lines are parallel if the slope of both lines is equal.

In other words,

If m₁ = m₂, then the lines will be parallel.

Now,

Given that the slope of the solid line = m₁ = 4

As the parallel lines have equal slopes.

Thus,

The slope of gas line = m₂ = 4

as  

m₁ = m₂

Therefore, we conclude that the parallel lines are equal and the slope of the gas line is:

m₂ = 4
