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.

Hi, I actually just took the test and got 100%
Remember: When plotting the points for this equation, make sure to always first plot the ones that correspond to the first linear equation, and then plot the ones that correspond to the second linear equation.
The points on the line should be for the first linear equation, (4,0) and (8,0). I got this answer by first converting the linear equation, 2x+y=8 from standard form to slope-intercept form. To do this, I subtracted 2x from both sides of the equation. So now it reads as y=8-2x. After this step was completed, I then graphed my first linear equation.
The points on the line should be for the first linear equation, (2,4) and (6,6).
I got this answer by first converting the linear equation, -x+2y=6 into slope-intercept form. To do this, I subtracted -x from both sides of the equation. Then I had to divide the 2 into both -x and 6. So now it reads as y= 6/2-x/2. After this step was completed, I then graphed my second and final linear equation.
I hope this helps!
Answer:
A = 422.5 m²
Step-by-step explanation:
Given the diameter of the circle = 23.2 m, we must divide this by 2 in order to solve for the radius:
Now that we have the radius, we can plug it in using the formula for finding the area of the circle:
A = π<em>r</em>²
A = (3.14)(11.6)²
A = 3.14 (134.56)
A = 422.5 m²
