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.

How many solutions are there to the following system of equations?

blagie [28]

Lets simplify these equations into slop-intercept form (y=mx+b)

When we do that, the equations turn to

y=-6x/24+10/6 or y=-1/4*x+5/3
y=-2x/8+7/8 or y=-1/4*x+7/8

When you do this, you see that the slope (m) is the same. This means that they are parallel lines. That means these lines will never meet, which means there will be no solution

Hailey rolls a twelve sided die, to choose a random number from one to twelve. What is the probability that the number hailey ro

Lemur [1.5K]

Answer:

7/12

Step-by-step explanation:

12 sided die has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 as the sides.

Two digits are 10, 11, and 12.

Even numbers are 2, 4, 6, 8, 10, and 12.

So two digits or even numbers are 2, 4, 6, 8, 10, 11, and 12. (7 total numbers)

P(Two digits or even) = 7/12
