How do I find the ratio of this? It makes no sense to me

Volgvan

Answer:

$\frac{169}{289}$

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b, then

ratio of areas = a² : b²

Here ratio of sides = 52 : 68 = 13 : 17 ← in simplest form, thus

ratio of areas = 13² : 17² = 169 : 289 = $\frac{169}{289}$

How do i turn standard form into slope intercept?

Jlenok [28]

Write it in y= mx+b form. Subtract 5x from both sides to get 4y = -5x + 100. Divide by 4 so the answer would be y= -5/4x + 25.

50 1/2 divided by 1/4 = 202<br> How are the numbers related?

Stels [109]

Answer:

see the explanation

Step-by-step explanation:

Let

$x=50\frac{1}{2}=\frac{50*2+1}{2}=\frac{101}{2}$

$y=\frac{1}{4}$

Find the ratio x/y

$\frac{x}{y}=\frac{(101/2)}{(1/4)} =\frac{101*4}{2*1}=202$

therefore

$\frac{x}{y}=202$

$x=202y$

That means----> The first number (50 1/2) is 202 times greater than the second number (1/4)
