Step-by-step explanation:
Consider the provided information.
The internal temperature falls to 20 degrees below the set temperature and turns off when the temperature reaches 5 degrees above the set temperature.
You preheat the oven to 405 degrees before putting a cake in and baking it for an hour at 405.
The internal temperature falls to 20 degrees, therefore the lowest set can be:
405-20=385 degree.
The temperature reaches 5 degrees above the set temperature 405, therefore the upper set is: 405+5=410 degree.
Hence, the temperature will be lying between 385 degree and 410 degree.
This can be written as:
Hence, the range of the oven is
Answer:
Step-by-step explanation:
A, B & C lie on a straight line.
D, C & E lie on a different straight line.
Ah, this is 2 intersecting lines
angles
y
= 106° and angle
z
= 64°.
well we know that a full size of circle is 360 degrees
let's add z and y :
106+64 = 170
then, let's subtract it from 360
360 - 170 = 90
we must devide it by 2, why? because 90 is from two section of x (2x)
so 90/2 = 45
and there you have it x = 45
if you still cannot visualize what is intersecting line mean, then see the file below
