Answer:
40.6 inches
Step-by-step explanation:
The plant's initial height is 7 inches tall.
It grows 1.3 inches each day for 27 days. This means that after 27 days, it must have grown an extra:
1.3 * 27 = 35.1 inches
It must have grown an extra 35.1 inches after 27 days. Therefore, its new height after 27 days is:
7 + 35.1 = 42.1 inches
The plant then begins falling over 0.5 inch for the next 3 days. After 3 days, it must have fallen over by a height:
0.5 * 3 = 1.5 inches
Therefore, after 30 days, the plant's new height is:
42.1 - 1.5 = 40.6 inches
The plant's height after 30 days is 40.6 inches
Answer:
Option B. $0.70
Step-by-step explanation:
First day fine = $0.10
Second day fine (doubled or $0.30 which is lesser)
= $0.10 + $0.10 [$0.10 is lesser than $0.30]
= $0.20
Third day fine = $0.20 + $0.20 [ $0.20 is lesser than $0.30]
= $0.40
Fourth day fine = $0.40 + $0.30 = $0.70
[$0.30 is cheaper than doubling the amount $0.40 + $0.40]
Therefore, the total fine for a book on the fourth day is $0.70
The probability that first a red bead is drawn and next a blue bead is drawn is 7/30,and both events are dependent
<h3>How to determine the probability?</h3>
The distribution of the beads are:
Red = 3
Blue = 7
Total = 10
The probability of selecting the red bead first is:
P(Red) = 3/10
When the red bead is selected, the number of beads becomes 9
So, the probability of selecting a blue bead is
P(Blue) = 7/9
The probability of the event is then calculated using:
P = 3/10 * 7/9
Evaluate
P = 7/30
Hence, the probability of the event is 7/30

Answer:
(n + 4) *2 = 11 * 2
Step-by-step explanation:
(n + 4) *2 = 11 * 2
Divide both sides by 2
n + 4 = 11
