Answer:
The valid range is 697 to 702
Step-by-step explanation:
<em>The question is incomplete; However, the requirement would likely be to determine the valid range which users can guess</em>
Given


First, we need to determine the minimum



Next, we determine the maximum


Hence:
<em>The valid range is 697 to 702</em>
Answer:
√71
Step-by-step explanation:
Simplify 42÷6 to 7
√64+7
Simplify 64+7 to 71
=√71
100 = 2t + 4f
40= t + f
-----------
get t or f by itself first.
f = 40 - t : Then substitute it back into for f in the other equation
100 = 2t + 4f
100= 2t +4(40-t)
100= 2t + 160 - 4t
100 = -2t + 160
-160 -160
<u>-60 </u>= <u>-2t
</u>-2 -2
t = 30 (Then plug this into either equation to solve for f)
Therefore,
t = 30 questions
f = 10 questions
Answer:
D = 
Step-by-step explanation:
given R =
multiply all terms on both sides to eliminate the fraction
3R = 3D - T ( add T to both sides )
3R + T = 3D ( divide both sides by 3 )
D =
