Answer:
The time it will take the population to grow to 800 insects is 17 days.
Step-by-step explanation:
The growth function of the insects is exponential.
The exponential growth function is:
Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = growth rate
<em>t</em> = time taken
It is provided that there were 270 insects after 9 days and initially there were 80 insects.
Compute the value of <em>r</em> as follows:
Now, compute the time it will take the population to grow to 800 insects as follows:
Thus, the time it will take the population to grow to 800 insects is 17 days.
If a shape is a square, this mean that each side has the same length. This means that each side of the square has a length of 17cm. Perimeter is the length of the outer boundary of a shape or the summation (addition) of all the sides. This means that the perimeter of this square is 17+17+17+17 or 17×4 which is equal to 68cm.
I hope this helps!
The correct answer is 20.7 inches of snow
Explanation:
The chart registers the total of snowfall at the school, in this, you can observe the total of snow in December was 3.4 inches, while in January the total was 12.3 and in February it was 8.4. Additionally, if you want to know the total during January and February combined the correct process is to add the two numbers. This means 12.3 inches (January) + 8.4 inches (February) = 20. 7 inches (Total in January and February.) Thus, the answer is 20.7 inches of snow.
Answer:
the volume of a cone = 1589.625feet³
Step-by-step explanation:
given that the diameter of the cone = 15inches
radius = 15inches/2 = 7.5inches
height of the cone = 27 inches
volume of the cone = ?
recall that
the formulae for finding the volume of a cone is given to be
= 1/3πr²h
the volume of a cone = πr² h/3
the volume of a cone = 3.14 × ( 7.5)² × 27/3
the volume of a cone = (3.14 x 56.25 x27)/3
the volume of a cone = 4768.875/3
the volume of a cone = 1589.625feet³
