Papessa [141]

Answer:

317,988,000

Step-by-step explanation:

We have been given that according to the United States Census Bureau, on September 11, 2014, the population of the United States was increasing by 11 people every 12 seconds.

Let us find number of people increased in 1 minute as:

$11\times \frac{60}{12}=11\times 5 =55$

Now, we will convert 11 years into minutes and multiply by 55 to find increase in population in 11 years.

$\text{11 years}=11\text{ years}\times \frac{365\text{ days}}{\text{year}}\times \frac{24\text{ hours}}{\text{days}}\times \frac{60\text{ min}}{\text{hour}}$

$\text{11 years}=11\times 365\times 24\times 60\text{ min}$

$\text{11 years}=5,781,600\text{ min}$

Upon multiplying 5,781,600 by 55, we will get:

$\text{Population increase in 11 years}=5,781,600\text{ min}\times \frac{55 \text{ people}}{\text{min}}$

$\text{Population increase in 11 years}=5,781,600\times 55 \text{ people}$

$\text{Population increase in 11 years}=317,988,000 \text{ people}$

Therefore, the population of United States would increase 317,988,000 in 11 years.

a flat-bottom reflecting pool has length 30 yards, width 10 yards, and depth 0.3 yard. Find th e surface area of the pool and th

Zigmanuir [339]

The surface area of the object above can be calculated by summing up all the areas of the surfaces. Therefore, we will have 5 surfaces with rectangles as the shape. The volume would be the product of the length, width and the depth. We calculate as follows:

SA = 2(depth)(length) + 2(depth)(width) + (width)(length)
SA = 324 yd^2

VOlume = 30x10x.3
Volume = 90 yd^3
