WELCOME TO CAHSEE Week Five
2
NOTES- any slide with a green title should be written down in your notebook.
3
Lesson #9- Measurement and Geometry 1.1
4
Ratios and Proportions (10mins) Ratio- comparing two amounts. 1 hour 60 minutes Proportions- two ratios that equal each other. 1 hour = 2 hours 60 minutes x minutes
5
Example (write down the entire problem) It takes you 3 hours to ride your bike from Downtown LA to Orange County. You ride the total 65 miles without stopping. What is your average speed in miles per hour? 3 hours = 1 hour 65 miles x miles 3x= 65 3 3 x= 21.66, round off to the nearest tenth= 21.7 miles per hour
6
Steps 1) Ratios= units must match! 3 hours = 1 hour 65 miles x miles **** Hours on top and miles on bottom. 2) Cross multiply 3) Divide to find x.
7
Bootcamp Practice (15 mins) Pages 77-78 you may write on.
8
Bootcamp Practice Raise your hand if you need any help Ask questions NOW, the Cahsee will be too late ! *Teacher will determine grouping (independent, pairs, etc.)
9
CHECK YOUR WORK- 2 mins Page 77 Problem #Answer 146.4 pounds 28976 feet 3151.2 feet per second
10
CHECK YOUR WORK Page 78 Problem #Answer 1128 ounces 2300,000 pounds 36.9 gallons 453.33 yards (wide) 58.8 miles per hour
11
Lesson #10- Measurement and Geometry 1.3
12
Rates- 8 mins Rate- type of ratio, amounts are related to each other.
13
Example #1 If you drove from Downtown LA to San Diego it would take your 2 hours for the 123 miles. What’s your car’s rate of speed? 123 ÷ 2= 61.5 miles per hour
14
Example #2 It took 7 workers 5 person- days each to complete a job. What was the total number of person-days needed to complete the job? 7x 5= 35 days
15
Bootcamp Practice (10 mins) Pages 82- 83- you may write on.
