Ashley is diving in the ocean. She wants to reach a coral reef that is 60 feet below sea level; that is, the reef’s elevation is -60 feet. She decides to safely descend to the reef from the ocean’s surface in increments of 10 feet. Answer the following questions to learn more about Ashley’s rate of descent

Part B
Write a numerical expression that represents the number of increments it will take Ashley to reach -60 feet.

Part C
Is the number of increments in part B positive or negative?

Part D
Rewrite the expression from part B by distributing -1 from each of the negative numbers.

Part E
If you divide any number by itself, what is the result? How can you apply this result to the expression in part D?

Part F
Based on your work so far, how many increments of -10 feet are in -60 feet?

Part G
Copy and paste this image into the space below the correct number of times to show an elevation of -60 feet.

Part H
Suppose that Ashley’s brother, Alex, makes the same dive in 4 increments instead of 6 Write a numerical expression to represent Alex’s elevation change in feet per increment.

Part I
How many negative numbers are in the expression in part H? What will the sign of the solution be? How do you know?

Part J
What was Alex’s elevation change in feet per increment?

Answer:

A:-10 or -10 feet

B:-60/-10 or -60 feet/-10 feet

C: The number of increments is positive.

D: -1 X 60/ -1 X 10 or -1 X 60 feet/ -1 X 10 feet

E: Any number divided by itself is 1. In the expression -1 X 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6.

F: There are 6 increments of -10 feet in -60 feet

G: copy and paste 6X

H:-60 feet / 4 increments

I: There is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.

J:-60/4 = -15 Alex's elevation change in each increment was -15 feet

Hope this helps

Answer:

Part B: is -60 divided by -10

Part C: is The number of increments is positive.

Part D: is -1 times 60 / -1 times 10

Part E: is Any number divided by itself is 1. In the expression -1 times 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6

Part F: is There are 6 increments of -10 feet in -60 feet.

Part G is: copy and paste -10 feet 6 times

Part H: is -60 / 4 increments

Part I: is there is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.

Part J: is -60 /4 =-15 Alex’s elevation change in each increment was -15 feet.

Step-by-Step Explaination: I did the test.
