Answer:
30 minutes will it take to reach its specified operating temperature from 25°C.
Step-by-step explanation:
Initial Temperature of oven = 25°C
Time taken by oven to reach 85°C temperature = 15 minutes
We have to find time taken by oven to reach at temperature of 145°C
Increase in temperature in 15 minute = 85 - 25 = 60°C
So, Time take by oven to increase 60°C temperature = 15 min
Time take by oven to increase 1°C temperature = 
Temperature we have to increase = 145 - 25 = 120°C
Time take by oven to increase 120°C temperature = 
Therefore, 30 minutes will it take to reach its specified operating temperature from 25°C.
<span>The tortoise crawls the whole 1000 m at 0.2 m/s, therefore, you must divide the distance by the rate of travel to find the time it took to complete the race. This gives us a time of 5,000 seconds to crawl the thousand meters. The hare runs the first 200 meters at 2 m/s, meaning that takes 100 seconds. The last 800 meters divided by the speed of 3 m/s gives us a time of 266 seconds. These two numbers must be added to the hare's rest time, converted from 1.3 hours into seconds by multiplying that number by 60 (for minutes in an hour) then 60 again (for seconds in a minute). 1.3 hours is equal to 4680 seconds. Therefore, the whole race took the hare 5,046 seconds, making it slightly slower than the hare, who finished in 5,000 seconds flat.</span>
Answer:
z=20.8
x=16.97
y=12
Step-by-step explanation:
The triangle on the right is a 30,60,90 triangle, a special right triangle with simple rules to find the side lengths. sides A,B, and C where C is the hypotenuse (24 in your diagram). The short side A is= 1/2 of side C (12 in your diagram). The long side B is= side A*√3 (20.8 in your diagram).
The triangle on the left is another special right triangle called a 45,45,90. The rules for this triangle are C= A*√2, and B=A. Because of the rules in the 30,60,90 triangle, we know that side A is 12. This means that side B (y)=12. Side C (x)= 16.97.
Hope this helped! Sorry if my explanation is confusing, but the rules for special right triangles can be easily found online and then calculated :)
