Terri can swim 3 laps in 2.5 minutes. To find how long it takes to swim 20 laps, you can make a proportion.
Put the amount of laps on the top and the time(minutes) at the bottom.
Cross multiply:
Divide by 3:
It would take Terri 
OR 
minutes to run 20 laps.
Answer:
A
Step-by-step explanation:
b must always be greater than 0 since 12b-15 must always be greater than 21. You can simplify the ineqaulity to see things easier; 12b>36. Again, this ineqaulity can be simplified; b>3. A is the closest answer here, but there should be an open interval at 3 for A to be correct.
The answer is 25%
you take (425/1700)*100
0.25 * 100% = 25%
Answer:
Independent events
Step-by-step explanation:
They are independent events because by "lands on yellow" and "lands on green", we're assuming that we're doing something like spinning a spinner, because then we're not taking anything and not replacing it. When we're replacing something, then that's an independent event, and by spinning a spinner once, for Event A, and again for Event B, then we're already replacing everything.
