1/4 of 1 minute would be 1/4 * 60(seconds in a minute)

so that would be 60/4=15 seconds.

Well we know a Minute is made up of 60 seconds so we want to break up 16 into 1/4 one fourths is breaking up the number into four parts like one dollar in 1/ fourth is $.25 so in this case one fourths of a minute is 15 seconds

Country A has a growth rate of 4.9% per year. The population is currently 4 comma 151,000, and the land area of Country A is 1

kvv77 [185]

Answer:

There will be one person on 1 square yard of land after 1,892,147.588 years.

Step-by-step explanation:

Continuous exponential growth formula:

$P(t)=Pe^{rt}$

P(t)= Population after t years.

P= Initial population

r=rate of growth.

t= time in year

Given that,

Growth rate of country A (r)= 4.9% per year=0.049 per year.

Initial population (P)= 151,000.

Land area of country area= 14,000,000,000 square yards.

There will be one person on one square yard of land.

So, there will be 14,000,000,000 person for 14,000,000,000 square yard of land in country A.

P(t)=14,000,000,000 person

$\therefore 14,000,000,000= 151,000 e^{0.049t}$

$\Rightarrow e^{0.049t}=\frac{ 14,000,000,000}{ 151,000}$

Taking ln both sides

$\Rightarrow ln|e^{0.049t}|=ln|\frac{ 14,000,000,000}{ 151,000}|$

$\Rightarrow {0.049t}=ln|\frac{ 14,000,000,000}{ 151,000}|$

$\Rightarrow t}=\frac{ln|\frac{ 14,000,000,000}{ 151,000}|}{0.049}$

$\Rightarrow t}=1,892,147.588$ years

There will be one person for every square yard of land after 1,892,147.588 years.

The humpback whales traveled 2240 miles in 28 days.

rodikova [14]

2,240 divided by 28= 80. 80 times 32= 2,560. 2,560+2,240=4800. Figure out the rest alone xD

Hello,

$\dfrac{5}{7^3}=5*7^x\\
5*7^{-3}=5*7^x\\

\boxed{x=-3}
