$\frac{k-m}{m} = \frac{n-k}{k} 
\\
\\k^2-mk=mn-mk
\\k^2=mn
\\k= \sqrt{mn} 
\\$

$7^2=4n
\\
\\n= \frac{49}{4}$

In a right-angled triangle, the hypotenuse is 113 and a leg is 112.

melomori [17]

Answer: 15

Step-by-step explanation: Use the formula: $a^{2}+b^{2}=c^{2}$

Remember $c^{2}$ should always be the hypotenuse or the longest side.

$112^{2}+b^{2}=113^{2}$ ---> evaluate the exponents

$12544+b^{2}=12769$ ----> subtract 12544 to the other side

$b^{2}=225$ ---> take the square root of both sides

$b=15$

sashaice [31]

Answer:

John Roberts must serve a minimum of 12, 543 days to surpass John Mrshall's record of justice.

Step-by-step explanation:

John Marshall = 2079 + 10, 463 = 12, 542 days

Now, we have to add 1 more day to pass John Marshall because if we do not, we would only be on the same level as John Marshall and NOT EXCEEDING him.

If you need 192 beads to make a necklace and bracelet and it takes 5 times more beads to make necklace than bracelet. How many b

Rasek [7]

192 = total beads

necklace + bracelet = 192

Let x equal the number of beads

bracelet = 5x
necklace = x

5x + x = 192

6x = 192

x = 32

It takes 32 beads to make a necklace
