Answer:
Step-by-step explanation:
Problem A
There are four outcomes for the cards
and three outcomes for the marbles
The total number of outcomes is 3 * 4 = 12
Problem B
Now you need 1 in three chances of getting a blue marble while any card will do. So your chances of drawing a blue marble are 1 in 3 and that is your final outcome because the cards don't affect the outcome.
Answer: 1/3
Answer:
Step-by-step explanation:
Let the number of cars be x and buses be y
<u>Then we have below inequalities as per given:</u>
- 5x + 32y ≤ 1310
- x + y ≤ 135
It is easy to notice that cars occupy 6 times less area than buses but cost of parking is 3 times less. So we would need maximum number of cars and minimum number of buses to maximize income
<u>Let's assume there are 135 cars and buses, then from the second inequality:</u>
<u>Substitute it in the first one:</u>
- 5(135 - y) + 32y ≤ 1310
- 675 - 5y + 32y ≤ 1310
- 27y ≤ 1310 - 675
- 27y ≤ 635
- y ≤ 635/27
- y≤ 23.5
The greatest number of buses is 23
Option D. 23 is correct
x-5= 0
move -5 to the other side
sign changes from -5 to +5
x-5+5= 0+5
x= 5
x-6= 0
x-6+6= 0+6
x= 6
Answer: B. 5 and 6
9/32 = x/320....9 fruit snacks to 32 students = x fruit snacks to 320 students
cross multiply
(32)(x) = (9)(320)
32x = 2880
x = 2880 / 32
x = 90 students <==
