Step-by-step explanation:
Let X = the number of days.
For growth rate,
y = X° × rate of growth, k
Where,
X° = initial amount of bacteria
k = rate of growth per day
Colby = 50 bacteria
kc = 2^(24/2 × X)
y = 50 × 2^(12X)
Jaquan = 80 bacteria
kj = 2^(24/3 × X)
y = 80 × 2^(8X)
Answer:
The answer of ur questions is may be its not final
=x=24
Given:
Admission to the local movie theater is $3 for each child and $7 for each adult.
A group of 12 people pay $64 admission.
To find:
The number of children in a group.
Solution:
Let the number of children be x and number of adults be y.
According to the question,
Total persons :
...(i)
Total cost :
...(ii)
Multiply equation (i) by 7 and subtract the result from (ii).



Divide both sides by -4.

Therefore, the number of children is 5.
Answer: -14y¹²
Step-by-step explanation:
To find the product, we want to multiply the coefficients and variables.
7y⁹·(-2y³) [multiply coefficients and variables]
-14y¹²
Therefore, the product is -14y¹².
So what you want to find is: what number times 120% is $324.00. (IT is 120% percent because it is the original <em>plus</em> the new percent) Simply set it up like so:
SN *120% = $324.00
Now turn the percent into a decimal:
SN * 1.20 = $324.00
Now divide $324.00 by 1.20
SN = $270
The original value of the basketball player's autograph was 270 dollars!
Hope that helps!
