$0.40 per ounce. This is because you divide 1.40 by 3 and you get 40 remainder 20. Then, 20 is the half. Thus, 20 multiply 2 is .40

A certain forest covers an area of 4000 km2. Suppose that each year this area decreases by 7%. What will the area be after 5 yea
Levart [38]
Answer:

2,600

Explanation:

Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.

Emma calculated the slope of the downhill hike to be . Her work is shown below. Determine whether her calculation was correct or
Greeley [361]

Answer:

  • Emma made a mistake. The slope should be -40.

Step-by-step explanation:

<u>Pair of points (x, y):</u>

  • (165, 900) and (180, 300)

<u>Slope formula:</u>

  • m = (y₂ - y₁)/(x₂ - x₁)

<u>Calculate the slope:</u>

  • Slope = (300 - 900)/(180 - 165) = -600/15 = -40
