Mathematics
1 answer:
dalvyx [7]2 years ago
6 0

Answer:

Step-by-step explanation:

This is 30°-60°-90° triangle, so the sides are in the ratio 1:√3:2

The side opposite the 30° angle is 10√3, so the side opposite the 60° angle is √3×10√3= 30, and the side opposite the 90° angle is 2×10√3 = 20√3.

How did the temperature change if :
Mkey [24]
<h3>Answer: Net Increase of 26%</h3>

===================================================

Explanation:

If it increases by 5%, then we use the multiplier 1.05

Think of it like saying 100% + 5% = 1 + 0.05 = 1.05

Similarly, an increase of 20% means we involve 1.20

Combine those multipliers to get: 1.05*1.20 = 1.26

This is a net increase of 26%

Interestingly, we get fairly close to 25% which is what many students might go for (since 5 + 20 = 25). This is a beginner's trap.

----------------

An example:

Let's say the temperature is 20 degrees Celsius (68 degrees Fahrenheit)

An increase of 5% means it moves to 1.05*20 = 21 degrees C

A 20% increase means we go to 1.20*21 = 25.2 degrees C

The shortcut would be to do a 26% increase to get 1.26*20 = 25.2 to help confirm we have the correct combined increase.
