By definition, the area of the square is given by:

A = L ^ 2

Where,

L: length of the sides of the square

Substituting values we have:

L^2 = 81

From here, we clear the length of the sides:

L = \sqrt{81}

L = 9

Then, the perimeter of the square is given by:

P = 4L

Substituting values we have:

P = 4 (9)

P = 36

Answer:

The perimeter of the frame is:

P = 36

We can used the Simpson's Rule says to approximate the area under a given curve using the following formula: 

<span>(Δx/3)[f(x0) + 4f(x1) + 2f(x2) + 4f(x3) + ... + 2f(xn-2) + 4f(xn-1) + f(xn)] </span>

<span>The pool is divided into 8 subintervals. We integrate the given function from 0 to 24, while the graph provides values of f(x) at 7 different points. The first value given, 6.2, is NOT f(0). It is f(3). Using Simpson's Rule, and dividing the lake of 24 meters into 8 subintervals, we write the equation: </span>

<span>area = (3/3)[f(0) + 4f(3) + 2f(6) + 4f(9) +2f(12) + 4f(15) + 2f(18) + 4f(21) + f(24)] </span>

<span>Pool area = 0 + 4(6.2) + 2(7.2) +4(6.8) + 2(5.6) + 4(5.0) +2(4.8) +4(4.8) + 0 = 126.4 m^2 </span>

<span>Rounding to the nearest square meter, the area of the lake is approximately 126 m^2 </span>

One nanometer equals about
Orlov [11]

Answer:

1\ \text{nanometer}=4\times 10^8

Step-by-step explanation:

Given : One nanometer equals about  0.00000004 inches.

To find : When writing this decimal as a single-digit integer multiplied by a power of ten, the single digit integer is  and the power of ten ?

Solution :

1\ \text{nanometer}=0.00000004

1\ \text{nanometer}=\frac{00000004}{100000000}

1\ \text{nanometer}=4\times 10^8

Therefore, the decimal as a single-digit integer multiplied by a power of ten is  1\ \text{nanometer}=4\times 10^8

What is the average speed of a runner if he ran 2 1/3 of a mile in 20 minutes?
lesya [120]
7 MPH because 2 1/3
in 20 minutes. So you multiply 20 by 3 you get 60. Then you multiply 2 by 3 you get 6. Then you multiply 1/3 x 3 and you get 1. 6=1=7                    Hope This Helps
