Module 06: Project Option 1
Instructions:

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.


Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.


Part 1: Writing Expressions
1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.


2. Translate the new algebraic expression you created in Question 1 to a verbal expression.


Part 2: Writing Equivalent Expressions
3. You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.


a. Use either the commutative property or combine like terms to create an equivalent expression.


b. Use the distributive property to create an equivalent expression.


4. Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.



Part 3: Finish the Story
5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did they earn?



6. Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

Answer:

The first two is x=60

Step-by-step explanation:

1.5/90 = 1/x

1.5x = 90 x 1

1.5x/1.5 = 90/1.5

x = 60

Answer:

a.  90/ 4.5 = 20 flags per yard

b.  4.5/ 90 = 0.05  = 5 hundredths of a yard

c. 0.75 x 3 colours = 2.25 yards

4.5 = 90 flags so 4.5/2 = 2.25 = 45 flags

Justifies she is correct when saying 45 flags can be made with 3 x 0.75 material as this is equal to 2.25 yards which is half of 4.5 yards equal to 90 flags.

To find 4.5 we have 3 pieces of material to begin with for part a and part b

This shows 1.5 x 3 = 4.5 yards

To find 2.25 we have 3 pieces of material in part c.

This shows 0.75 x 3 = 2.25 yards

Answers

We can solve this by calculating the arch lengths on the track and adding them to the straight lengths on the track.

To calculate the arch lengths, we can pretend the arches are semicircles and calculate the arch length. We know that the diameter is 100 meters, and the circumference formula is diameter times pi. 100 times pi is 314, using 3.14 as pi, but we divide this by two since we are calculating the arch length of a semicircle, not a full circle. Dividing 314 by two gives us 157. However, we multiply this by two since we have to include the other arch's length and the lengths are the same, giving us 314 again. adding this to 200, the straight side lengths of the track, we get our final answer, 514 meters.

what is the surface area of the box if it is scaled up by a factor of 10?
list dimensions

Length: 9.5 inch which is 24 cm

Width: 2.8 inch which is 6 cm

Height: 13 inch which is 33 cm

Answers

A for a box, the surface area is given by:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in
