Answer:
area =length ×breath =10×6=60
694
you just subtract 1212 by 518
694+518=1212
based on the number of marbles in the bag, the number of marble groups possible is 7,140 groups.
the probability of selecting 2 red and 1 yellow is 1/68.
<h3>what number of 3-marble groups can be made?</h3>
first, find the number of marbles:
= 7 + 8 + 9 + 7 + 5
= 36
the number of marble groups are:
= 36 ! / (3 ! x 33 !)
= 7,140 groups
the probability of picking 2 red and 1 yellow is:
= (( (7! / (2! x 5!)) x ( ( 5! / (1! x 4!))) / 7,140
= 1 / 68
= 1.47%

Answer:</h3>
a=45
<h3>
Solution:</h3>
- We need to multiply both sides by 3 in order to get rid of the denominator, 3:
- 2/3a•3=30•3
- 2a=90
- Divide both sides by 2:
- a=45
