After 79 weeks the tanks will have the same amount of water.
948-7*79=395
711-4*79=395
1 ft = 12 inches....so 10 ft = (10 * 12) = 120 inches
each strip of wall paper is 20 inches...
so 120/20 = 6 strips of wall paper are required <==

Answer:
0.8
Step-by-step explanation:
P(AP statistics) = 65%
P(AP Calculus) = 45%
P(AP statistics n AP Calculus) = 30%
Probability of AP statistics or AP Calculus but not both :
Probability of event A or B :
P(AUB) = p(A) + p(B) - p(AnB)
P(AP statistics U AP Calculus) = P(AP statistics) + P(AP Calculus) - P(AP statistics n AP Calculus)
= 0.65 + 0.45 - 0.30
= 0.8
= 80%
