Answer: Ix - 950°C I ≤ 250°.
Step-by-step explanation:
Ok, the limits are:
700°C to 1200°C.
The first step is to find the mean these numbers:
M = (700°C + 1200°C)/2 = 950°C
Now let's find the distance between the mean and the limits (which is equal to half the difference between our numbers)
D = (1200°C - 700°C)/2 = 250°C.
Now we can write our relation as:
Ix - MI ≤ D
Ix - 950°C I ≤ 250°.
if x = 1200°C.
I1200°C - 950°CI = 250°C ≤ 250°C ---- true.
if x = 700°C
I700°C - 950°CI = I-250°CI = 250°C ≤ 250°C ---- true

Answer:
Step-by-step explanation:
Right triangle:
height h, width w, hypotenuse h
Area is: 
Pytagoras theorem: 
In this question:
To find the area, in terms of h and t, we have to write w as a function of h and t. So
So the area is:
Ok so ratios
john casts a shadow of 180 when he is 180
therefor shadowheight=realheight
320shadowheight=realheight
realheight=320centimeters
