Finding two geometric means between 10 and 125:
a 1 = 10, a 4 = 1250
a 4 = a 1 * q^3
1250 = 10 * q^3
q^3 = 1250 : 10
q^3 = 125
q = 5
a 2 = 10 * 5 = 50
a 3 = 10 * 5² = 10 * 25 = 250
Answer: The two geometric means are: 50 and 250, since 10, 50, 250 , 1250 forms a geometric sequence.
Answer:
Plan C
Step-by-step explanation:
Complete the table first:
To find the number of weeks for each amount of $ to save, divide $500 by the amount.
Plan B: $500/$30 = 16.7 weeks, rounded to 17 weeks
Plan C: $500/$40 = 12.5 weeks, rounded to 13 weeks
Plan D: $500/$50 = 10 weeks
Save $500 in less than 16 weeks with $20 extra:
Which plans need less than 16 weeks?
Plans C and D.
Check the amount of money Plan C gives:
In 13 weeks, how much extra money does this plan give?
Extra money = Total - $500
The total money is 13 weeks * $40 = $520
$520 - $500 = $20 in extra money
Therefore Plan C gives Todd $500 in less than 16 weeks, with $20 extra.
