HELP PLS.Sonia takes a 4/5-mile walk every day. What part of her walk has she completed once she has walked 3/5 mile?

So, the question’s a bit weird, but I’m going to assume it’s asking for what fraction of her walk she had completed:

Basically you need to divide 3/5 by 4/5

Dividing a fraction is the same as multiplying as the reciprocal of the fraction (the top and bottom get reversed)

Therefore you need to find 3/5 • 5/4

Solving this should get you 15/20, which can be simplified to 3/4.


So the answer is she has completed 3/4 of her walk (75%)

What is the equation of a line that contains point (4, –3) and is PARALLEL to –4x + y = 7?
Debora [2.8K]

Answer:

Step-by-step explanation:

First, put -4x+y=7 into y=mx+b format

move -4x to the other side (or add 4x on both sides)

y=4x+7

now, parallel lines have the same slopes, but not the same y intercepts.

So, you already know the slope of your new line

y=4x+b

now we need to find b (y intercept)

take the point (4,-3) and put it into the equation above

-3=4(4)+b

-3=16+b

move 16 to the other side (or subtract 16)

-19=b

therefore the new line will be y=4x-19

Hope this helps!

Three consecutive integers add up to -36. What are the integers?​
nasty-shy [4]

Answer:

We know our answer is correct because 11 + 12 + 13 equals 36 as displayed Below

Explanation

3X + 3 = 36 3X + 3 - 3 = 36 - 3 3X = 33 3X/3 = 33/3 X = 11 Which means that the first number is 11, the second number is 11 + 1 and the third number is 11 + 2. Therefore, three consecutive integers that add up to 36 are 11, 12, and 13. 11 + 12 + 13 = 36 We know our answer is correct because 11 + 12 + 13 equals 36 as displayed above. Therefore, three consecutive integers that add up to 36 are 11, 12, and 13.  11 + 12 + 13 = 36

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.
