Answer:

273

Step-by-step explanation:

To start off, lets convert 9% into the decimal form so we can solve this problem easier. 9% would become 0.09 in its decimal form. Next, follow the math below...

(300) x (0.09) = 27

Now, since Brian's cholesterol level was reduced, we know we have to subtract. We can finish the problem now...

300 - 27 = 273

Brian's new cholesterol level is 273.

A cryptographic hash takes a message as input and produces a fixed-length string as output, called the digital fingerprint. A br
Allushta [10]

Answer:

1.85x10^{19} attempts are required to find a matching pair if the digital fingerprint is 64 bits long.

3.40*10^{38} attempts are required to find a matching pair if the digital fingerprint is 128 bits long.

Step-by-step explanation:

Each bit has two options. So

How many attempts are required to find a matching pair if the digital fingerprint is 64 bits long?

So for each of the 64 bits, we have the following number of options.

2 - 2 - 2 - 2 -... - 2

So, in all, there are

T = 2^{64} = 1.85x10^{19}

options.

So, 1.85x10^{19} attempts are required to find a matching pair if the digital fingerprint is 64 bits long.

128 bits long?

Using the same logic as the first question.

T = 2^{128} = 3.40*10^{38}

So, 3.40*10^{38} attempts are required to find a matching pair if the digital fingerprint is 128 bits long.

The length of a rectangular garden is 5 less than triple
Lubov Fominskaja [6]

Answer:

Width = 10 feet, Length = 25 feet

Step-by-step explanation:

the width is x

the length is 3x-5

so, 2(x+(3x-5))=70 is the equation

2(x+3x-5)=70

2x+6x-10=70

8x-10=70

8x=10

x=10.

Width = 10 feet

Length = 25 feet

10) Find the distance between (2, 3) and (-3, -2) A) 2 B) 5 C) 50 = 5 2 D) 25
PSYCHO15rus [73]

Answer:

The answer is

<h2>5 \sqrt{2}  \:  \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2, 3) and (-3, -2)

The distance between them is

d =  \sqrt{( {2 + 3})^{2} +  ({3 + 2})^{2}  }  \\  =  \sqrt{ {5}^{2}  +  {5}^{2} }  \\  =  \sqrt{25 + 25}  \\  =  \sqrt{50}  \\  = 5 \sqrt{2}

We have the final answer as

5 \sqrt{2}  \:  \:  \:  \: units

Hope this helps you
