A town with a population of 5,000 grows 3% per year. Find the population at the end of two years using the Growth and Decay meth

jenyasd209 [6]

The population would be 5300 at the end of two years because 3% of 5000 is 150 so 150x2=300. 5000+300=5300

Feliz [49]

Answer:

Step-by-step explanation:

Let's simplify step-by-step.

−22−3+40+6y+7+3c

=−22+−3+40+6y+7+3c

Combine Like Terms:

=−22+−3+40+6y+7+3c

=(3c)+(6y)+(−22+−3+40+7)

=3c+6y+22

Answer:

=3c+6y+22

Two pipes are used to fill a 300-gallon tub with water. The wide pipe can fill the tub in x hours. The narrow pipe can fill the

Hoochie [10]

Answer:

$\frac{6}{x}-\frac{7}{y}=\frac{7}{12}$

Step-by-step explanation:

#We know that the filling taps will run for a cumulative 4hrs each while the draining hole will empty for a combined 7hrs.

Let x be the rate of the first filling tap, and 2x of the 2nd filling tap and y be the rate of the hole.

#The rate at which the tub fills per hour is :

$V_{tub}=\frac{1}{x}+\frac{1}{2x}-\frac{1}{y}\\\\=\frac{1}{x}(1+\frac{1}{2})-\frac{1}{y}\\\\=\frac{3}{2x}-\frac{1}{y}$

#The volume of the tub at the instant moment the leak is repaired is expressed as:

$V_{tub}=\frac{3}{2x}t_1-\frac{1}{y}t_2=\frac{7}{12}, \ \ \ \ \ \ t_1=4,t_2=7\\\\\\\frac{3}{2x}\times 4-\frac{1}{y}\times7\frac{7}{12}\\\\\\\frac{6}{x}-\frac{7}{y}=\frac{7}{12}$

Hence, the volume of the tub after the leak is repaired is expressed as $\frac{6}{x}-\frac{7}{y}=\frac{7}{12}$
