6D Finish converting 7/9 into a decimal and percent if you haven't yet; then complete problems #1 through 5 on the fraction operations worksheet.

grade 6 hw due NEXT TIME I SEE YOU (6D mon/6S tues), p427 #5abc, 6abc

7Fa STUDY for your EXAM!! (please remember to come prepared)

7F:
1) The ordered pairs (-50, -24) and (20, 4) lie on a line. Calculate the slope between them, algebraically find the y-intercept, then write the equation of the line in slope-intercept form. Then draw the graph of the line.
2) Rewrite 9 - 3y = 6x in slope-intercept form. Identify the slope and the y-intercept, and draw the graph of the line.
3) Suppose you have a square whose perimeter is 64cm. Inside of the square you have a half-circle whose diameter is 10cm. Draw a sketch of this. Find out what area would be left if you cut the half-circle out of the square.

6S p406 #2all. Use the area formula for triangles that was given in class. Write the formula each time and show your steps. If you need another explanation, click here for an exciting instructional video!

6S pp400-401 #6d,f, #7c. Do drawings for all BUT #7c you might want to make a sketch bc the dimensions are pretty big. See p398 example 3 if you need help. Please also bring your corrected polygon/angle quiz!

6D pp400-401 #6d,f, #7c. Do drawings for all BUT #7c you might want to make a sketch bc the dimensions are pretty big. See p398 example 3 if you need help
