Answer: 5489
Step-by-step explanation:
Given the following :
Growth rate (r) = 19% per hour
Sample culture in population = 2300
Size of sample after 5 hours =?
Using the exponential relation:
P = Po * r^t
P = population after 5 hours
Po = Initial sample population
t = time
P = 2300 * (1 +19%)^t
P = 2300 ×(1 + 0.19) ^5
P = 2300 * 1.19^5
P = 2300 * 2.3863536599
P = 5488.61341777
P = 5489 (nearest integer)

Answer:
No solution
Step-by-step explanation:
Note how "2x" shows up in both equations. This suggests doing a substitution to solve the system.
Focus first on the first equation. Solving 2x - y = 7 for 2x, we get:
2x = y + 7.
Next, we substitute y + 7 for 2x in the second equation:
y = (y + 7) + 3.
Simplifying this produces:
0 = 10
This is not true and can never be true. Thus, this system has no solution.
Answer:
1296 ft^3.
Step-by-step explanation:
The ratio of the volumes = 1^3 : 6^3
= 1 : 216.
So volume of the larger figure = 6 * 216
= 1296 ft^3.
Answer:
<h3>The answer is 10.42 %</h3>
Step-by-step explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual mass = 240 g
error = 265 - 240 = 25
So we have
We have the final answer as
<h3>10.42 %</h3>
