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 = $\frac{169}{289}$

A temperature of –25°c is equivalent to:<br> a. 248 k.<br> b. 25 k.<br> c. –25 k.<br> d. 298 k.

SpyIntel [72]

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:

T(K) = T(°C) + 273.15;

So, T(K) = -25 + 273.15;

T(K) = 248.15;

The correct answer is a.
