Answer:

49.6 square meters

Step-by-step explanation:

first, circumference is 2*pi*r, so we want to find r. so we take 2*pi*r=24.8 and solve for r which is 4.

Now, area is pi*r^2 so pi*4^2 = pi*16 = 49.6

49.6 square meters.

First, let’s find the radius of the rug. The radius is equal to the circumference divided by 2pi, or 2 * 3.1, which is 6.2, in this case.

24.8/6.2

4

The radius is 4. The area of a circle is pi times the radius squared.

3.1 * 4^2

3.1 * 16

49.6

So, the area of the rug is 49.6 square meters.

Answer: 21

Step-by-step explanation:

$N-\left(2\cdot \:7\right)=7$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$N-2\cdot \:7=7$

$\mathrm{Multiply\:the\:numbers:}\:2\cdot \:7=14$

$N-14=7$

$\mathrm{Add\:}14\mathrm{\:to\:both\:sides}$

$N-14+14=7+14$

$\mathrm{Simplify}$

$N=21$

About 2,000,000 people visited the aquarium last year. If this number were rounded to the nearest million, what was the greatest

notsponge [240]

Okay, so there's a number rounded to the nearest million, in this case 2 million. So this tells me that the number of visitors is between 1,500,000 and 2,499,999. The reason why 1,499,999 doesn't count is because the hundred thousands digit is not 5 or above, so it doesn't count. It would round down to 1 million, not 2 million. The reason why 2,500,000 doesn't count, is because the hundred thousands digit is 5, so that rounds to 3 million, not 2 million. The greatest number of visitors that visited the aquarium has to be 2,499,999, because that's one digit away from 2.5 million, and the hundred thousands digit is a 4, not 5. The answer is 2,499,999

Solve for the roots in the equation below. In your final answer, include each of the necessary steps and calculations.

Nostrana [21]

$x^3-27i=0$
$x^3=27i$
$x^3=27e^{i\pi/2}$
$x=\left(27e^{i\pi/2}\right)^{1/3}$
$x=3e^{i(\pi/2+2\pi k)/3}$
$x=3e^{i\pi(4k+1)/6}$

where $k\in\{0,1,2\}$ . This means you have

$x=3e^{i\pi/6}=\dfrac32(\sqrt3+i)$
$x=3e^{i5\pi/6}=\dfrac32(-\sqrt3+i)$
$x=3e^{i9\pi/6}=-3i$

as the solutions to the original equation.
