we know that
1) Lily swims a -meter race
2) She swims the first half in seconds
3) She swims the second half in seconds
so
To find the total time to swim the whole race sum the time in the first half plus the time in second half
therefore
<u>the answer is</u>
Subtract original amount from new amount:
84 - 39 = 45
He bought 45 books.
First choice is "1 of 10 grape lollipops from 35 lollipops"
The probablity is 10/35 = 2/7
Second choice is "1 of 18 apple lollipops from 34 lollipops"
So probablity is 18/34 = 9/17
Between this is AND so you have to these probablities multiply:
P(A) = 2/7 * 9/17 = 18/119
P(A) = 18/119 * 100% = 1800/119 %
It is approximaly 15,1 %.
A segment? ????? Not so sure about that one
