a²+b² = c² where a and b are legs and c is the hypotenuse

So...

a²+4²=13²

a²+16=169

a²=153

a=√153

answer: approx. 12.37 units

The equation would be a^ + 4^ = 13^

First we need to bring the numbers to the second power, 4 to the second would be 16, 13 to the second power is 169.

Then we subtract 16 from 169, which equals to 153.

Then we "square root" the 153 because of the 2nd power on top of the a

The correct answer would be 12.4

I hope this helps :)

STAY SAFE!! :D

\bf{\cfrac{1}{2}}

\Large\texttt{Process}

Do you remember that we cannot add fractions when they have unlike denominators? We can onyl add fractions as long as they have the same denominator!

So here's the big idea: fractions must have the same denominator.

If we multiply the first fraction by 2, then both fractions will have the same denominator. *

* <em>Why 2??</em>

<em />

-  Because:

We need to find the least common multiple of 3 and 6, which is 6. Next, what should 3 be multiplied by to result in 6? That's right, 2.

Also, we can only multiply the denominator by 2 as long as we multiply the numerator by 2!

So that's why we multiply the whole fraction by 2

\bf{\cfrac{1\times2}{3\times2}+\cfrac{1}{6}}

Watch what happens

\bf{\cfrac{2}{6}+\cfrac{1}{6}}

Add the numerators

\bf{\cfrac{2+1}{6}}

\bf{\cfrac{3}{6}}

Simplifying the fractions

\bf{\cfrac{3\div3}{6\div3}}

\bf{\cfrac{1}{2}}

Hope that helped

Answer:

  $4.00

Step-by-step explanation:

We assume the price is proportional to the quantity of oranges. If p is the desired price in dollars, we want ...

  p/8 = 0.25/(1/2)

  p = 8(0.50) = 4.00 . . . . multiply by 8, simplify

8 kg of oranges would cost $4.00.
