8th Grade Math

Welcome to Eighth Grade Math with Mr. Scapellati!

**CR Problems (to be completed neatly with ample work on loose leaf and/or graph paper and turned into the bin on Tuesday, 5/8 during HOME ROOM):
1) Solve 2(3p - 4) = 10
2) Jordan and Missy are standing in the school yard. Jordan, who is 6 feet tall, casts a shadow that is 54 inches long. At the same time, Missy casts a shadow that is 45 inches long. How tall is Missy?
3) What is the probability of not rolling a 5 on a single toss of a number cube?
4) What is the product of 10x^4y^2 and 3xy^3?
5) Sal keeps quarters, nickels, and dimes in his change jar. He has a total of 52 coins. He has three more quarters than dimes and five fewer nickels than dimes. How many dimes does Sal have?
6) Convert 0.000000468 into scientific notation.
7) If g(x) = 12 - 5x, what is the value of g(-7)?
8) What is the image of the point (-3, 4) after a reflection across the y-axis and then a translation three units left and two units up?
9) What is the definition of a function?
10) The graph of the equation x + 3y = 6 has what point as its y-intercept?

TEST CORRECTIONS

Students must follow this exact format to be eligible for earning points back:

For each exercise that was partially/completely wrong:

1) Write out the entire question.

2) Complete the exercise correctly with ample work.

3) Provide a brief reason as to why it was marked off the first time.

This should all be done neatly on loose leaf, stapled to the back of the signed test, and turned into the math bin within three days of class return.
