A ruler because it gies you the exact measurement in inches, or centimeters and you can always multiply to find out how many feet something is.
Given:
Initial population = 100 algae
Growth rate = 30% per day.
Time = 5 days
To find:
The future amount of population.
Solution:
The exponential growth model is
where, a is the initial value, r is the rate of interest in percent and t is time period.
Substituting the given values, we get
Now, solve this.
Therefore, the future value is 371.293 algae.
Answer:
(a) The angle swept by the hour hand is 297⁰30′
(b) The exact angle between the minute and hour hand is 132⁰30′
Step-by-step explanation:
Given;
(a) angle swept by the hour hand between noon and 9:55 pm
between 12 pm and 9pm, there are 9 hours = 9 x 60 = 540 mins
9.55 pm = 540 mins + 55 mins = 595 mins
The hour hand moves 0.5 degree per minute
1 mins ---------------- 0.5 degrees
595 mins --------- ?
= 297⁰30′
(b) the exact angle between the minute and hour hands at 1:25 pm
for 25 mins, the hour hand had moved 12.5 degrees
Between 1 and 5, there are 20 mins moved by the minutes hand = 20 x 6°
= 120⁰
total angle = 12.5⁰ + 120⁰ = 132⁰30′
