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}

On the radio one morning, a weather reporter stated that the tempature was two degrees below zero, but the tempature would cotin
Anna71 [15]

Answer:

T ≥ -2

Step-by-step explanation:

Given

Temperature = 2° below 0°

Required

Represent as an inequality

First, we need to calculate the temperature in the morning.

2° below 0 means.

Temperature = 0° - 2°

Temperature = -2°

Next, we determine the temperature at any time.

The question says the temperature continues to rise during the day.

Represent this with T

This means T will be greater than -2°

However, we need to consider where the temperature started from.

In other words, T = -2

Combine T = -2 and T = -2 together, we have:.

T ≥ -2

Hence, the inequality that represents the scenario is T ≥ -2
