Set 4 is the correct answer because if you multiply 10 by 10 + 20 times 20, you will get 400 and when you multiply 30 by 30 you also get 400 which is equal to 400 there for you answer would be set 4.

Hope I helped if I did click the thx button ;)

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 radius of a sphere is 6 units.

skad [1K]

Answer: Four-thirdsπ(6)³

Step-by-step explanation: The formula for the volume of a sphere is attached in the image down below.

Notice that two of the options listed have three-fourths but we use four-thirds to find the volume of a sphere. This means that we can eliminate the 1st and the 3rd option.

Now, we will multiply that by π and then by the radius cubed which is also written as 6³. This means that our answer would be the second option.

What is 100kg decrease by 12.5%

erma4kov [3.2K]

Answer:

87.5

Step-by-step explanation:

100 - (12.5% × 100)

100 - 12.5% × 100

(1 - 12.5%) × 100

(100% - 12.5%) × 100

87.5% × 100

87.5 ÷ 100 × 100

87.5 × 100 ÷ 100

8,750 ÷ 100 = 87.5
