Answer:
Step-by-step explanation:
height=√(13²-9²)=√(13-9)(13+9)=√4(22)=2√11
area=1/2×9×2√11=9√11≈29.85 ft≈29.9 ft
Multiply her speed by the amount of time:
3 1/3 x 2 hours = 6 2/3 total miles
4ab^2
Hoped this helps! Just had it on a quiz and got it right. If you have boxex by 4 a^1 b^2
Standard z score = (11 - 10 ) / 5 = 0.2
From the tables the probability = 0.0793 = 7.93%
X = number of right-handed gloves
12 - x = number of left-handed gloves
45x + 52 (12 - x) = 561
distribute
45x + 624 - 52x = 561
combine like terms
-7x + 624 = 561
subtract 624 from both sides
-7x = -63
divide both sides by -7
x = 9 (amount of right handed gloves)
12 - 9 = 3 (amount of left handed gloves)
