Answer:
Jennifer
4/15 mph
Step-by-step explanation:
First, we find the two speeds in miles per hour.
Victoria:
1 1/5 mile per 1/2 hour = (1 1/5 mile)/(1/2 hour) = 2 2/5 mph = 2.4 mph
Jennifer:
2/3 mile per 1/4 hour = (2/3 mile)/(1/4 hour) = 8/3 mph = 2 2/3 mph
2 2/3 mph > 2 2/5 mph, so Jennifer's speed is greater.
The difference in speeds in mph is:
2 2/3 - 2 2/5 = 2 10/15 - 2 6/15 = 4/15
Here, number of periods (years), n=5
Annual interest rate, i=0.05 (compounded yearly)
Present value/deposit, P=100
Future value of deposit = P(1+i)^n=100(1.05^5)=127.63 (to the nearest cent)
Answer: After 5 annual interest payments, Bob will have 127.63 in his account.
Answer:
one ten was traded for ten ones
Step-by-step explanation:
372 cannot be divided by 3 easily. However, 360 +12 can be divided by 3 easily, so it makes sense to trade one of the seven tens for ten ones. That will leave 6 tens, but give twelve ones.
370 +2 = 360 +12 . . . . where the "+" numbers are the numbers of ones
It's a 2nd degree algebraic expression in ' y '.
It's pretty messy in this form, and it can be substantially cleaned up.
Looking at just the second term, we can remove the parentheses:
3 (4y² - 2) = 12y² - 6
Now we can put that into the original expression ... 3y² + 12y² - 6
then combine the y² terms: <em>15y² - 6</em> .
If you want to go one step farther, we can factor it: <em>3(5y² - 2) </em>
