23% of what number is 80? can you explain how you get the answer

timofeeve [1]

I got 347 as the number because 23% of 347 is almost 80.
(<span>23 *<span>347)/100 = 79.81

23*347= 7981
7981/100 = 79.81
Round that and you get 80.</span></span>

alekssr [168]

Answer:

Other Side (B) = 9.45 inches

Step-by-step explanation:

Given:

Hypotenuse = 10 inches

Other Side (A) = 3.25 inches

Find:

Other Side (B) = ?

Computation:

According to Pythagoras theorem:

$Hypotenuse^2= (Perpendicular)^2+(Base)^2\\\\Hypotenuse^2= (A)^2+(B)^2\\\\10^2= (3.25)^2+(B)^2\\\\100=10.5625 +(B)^2\\\\89.4375 = (B)^2\\\\B=\sqrt{89.4375}\\\\B=9.4571$

Other Side (B) = 9.45 inches

Decompose fraction 2 3/4

ludmilkaskok [199]

Answer:

11 * 1/4

Step-by-step explanation:

Hi!

Since to decompose a fraction means to basically take it apart, that's all we have to do!

Breaking down the fraction, we can see that it is composed of a bunch of 1/4.

(As an improper fraction below.)

$\frac{11}{4}$ .

That's just $11 \cdot \frac{1}{4}$ .

Thus, the answer is $\boxed{11\:\cdot\:\frac{1}{4}}$ .

Hope this helps!
