Answer:
6.99
Step-by-step explanation:
11.99+2.99+5.99=20.97
20.97/3=6.99
First find the decimal values of both fractions:
7/10 is 7 divided by 10 so:
= 0.70
3/5 is 3 divided by 5 so:
= 0.60
60 minutes is one hour (since the question said that Lola rides the bike for 7/10 and 3/5 of an hour)
Now we use these to find how many minutes:
To find 0.70 (or 7/10) of 60 minutes, you multiply 60 x 0.70
= 42 minutes on Saturday
To find 0.60 (or 3/5) of 60 minutes, you multiply 60 x 0.60
= 36 minutes on Sunday
Now to find how much longer she rode her bike on Saturday than Sunday, you subtract the two numbers:
42 - 36
= 6
Therefore, Lola rode her bike for 6 minutes more on Saturday than on Sunday.

Determine the probability of red then blue jelly? i.e. P(R and B)
From the question, we understand that the red jelly bean was not replaced. This means that the number of jelly beans reduced by 1 after the picking of the red jelly bean
So, we have:
This is then solved further as:
The probability has a denominator of Total - 1 because the number of jelly beans reduced by 1 after the picking of the red jelly bean
The equation becomes:
5 + (-10) = 5 - 10
= -5 .
5 + (-3) = 5 -3
=2 .
5 + 3 = 8 .
5 + 0 = 5 .
