Complete question :
In Hawaii a volcano is about to explodel At 6:00 am a device placed inside the volcano
measures the temperature at 69.5 degrees Celsius. Every 3 minutes the temperature
rises 1/5 a degree. If the Volcano explodes at 145.5 degrees Celsius how many hours do
they have to evacuate a nearby city?

Answer:
19 hours
Step-by-step explanation:
Given that:
Temperature of volcano at 6:00 am = 69.5°C
Average rise in temperature per 3 minute = 1/5
Hence, rise in temperature per minute = 0.0666666°C
Temperature at which volcano will explode = 145.5°C
Hence, change in temperature :
(145.5°C - 69.5°C) = 76°C
Hence, temperature will have to rise by 76°C
Rise in temperature / rate of temperature increase
= 76°C / 0.0666666°C
= 1140.0011 minutes
= 1140.0011 / 60
= 19.0000019 hours
= 19 hours

Answer:
A possible measure of Line segment TS is 4.0 ft
Step-by-step explanation:
<u><em>The options of the question are</em></u>
1.6 ft 3.0 ft 3.2 ft 4.0 ft
we know that
In any triangle:
The shortest side is always opposite the smallest interior angle.
The longest side is always opposite the largest interior angle
In this problem
That means
Rewrite the expression
so
therefore
A possible measure of Line segment TS is 4.0 ft
