A particular type of cell increases by 75% in number every hour. Find the number of cells present at the end of 12 hours if ther
prisoha [69]

We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.

We will use exponential growth formula to solve our given problem.

y=a\cdot (1+r)^x, where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

75\%=\frac{75}{100}=0.75

Upon substituting initial value a=4 and x=12 in above formula, we will get:

y=4\cdot (1+0.75)^{12}

y=4\cdot (1.75)^{12}

y=4\cdot 825.0050068497657776

y=3300.020027

y\approx 3300

Therefore, there will be approximately 3300 cells at the end of 12 hours.

Aleks [24]
Denise would have to take seven hours to charge the same amount of money as tiana. furthermore, it would cost the same amount as that is what the prompt is asking for.

to get the answer:
i subtracted $19 from $292 to eliminate the
fee element because if you were to divide
$292 by $39 without the step, the hours would be incorrect and the price would be greater.

after subtracting i got $273

from there i divided $273 by $39 and got 7 (the amount of hours it would take)

Solve for t. You must write your answer in fully simplified form. <br><br> −19=7t
nikitadnepr [17]

Answer:

t=-19/7

Step-by-step explanation:

you need to isolate for t which means you need to get t all alone on one side of the equation. Do do that you can divide both sides by 7. This gives you -19/7=7t/7

we know that anything divided by itself is 1 so we get -19/7=t

This is the simplest for because 19 and 7 are both prime numbers, so you can't simplify them.

Murrr4er [49]

Answer:

452\ ft^{3}

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

V=\pi r^{2} h

we have

r=12/2=6\ ft ----> the radius is half the diameter

h=4\ ft

substitute the values

V=(3.14)(6^{2})(4)=452\ ft^{3}
