V=2 BECAUSE
7v2+1=29
7v2=28
v2=4
v=2
7/8 = x/48
Perform cross multiplication:
a/b = c/d
ad = bc
a = 7 ; b = 8 ; c = x ; d = 48
7*48 = 8x
336 = 8x
336/8 = x
42 = x
7/8 = 42/48
42 ÷ 6 = 7
48 ÷ 6 = 8
Answer
112 square feet no
Explanation
I just multiplied I remember solving it that way when I was in middle school
The six sided die has 6 sides (with numbers 1,2,3,4,5 and 6). That's why the probability to roll number 2 in one trial is equal to

.If you'll dol 50 trials, then you can expect

times to roll number 2 (8 or 9 times).
