Answer:
9.6 miles
Step-by-step explanation:
Let x represent the round trip distance. Then Michelle's time was ...
t = distance/speed
1 = (x/2)/8 +(x/2)/12 = x(1/16 +1/24) = x(3/48 +2/48) = x(5/48)
48/5 = x = 9.6
The round trip is 9.6 miles.
System of equations:
w=(3/2)*h (1)
w*h=54 area (2)
w=54/h substitute into (1)
54/h=3h/2
3h²=54*2
h²= 36 (we take only positive solution)
h = √36=6
h=6 in.
w=(3/2)*h=(3/2)*6= 9
w=9 in.
correct answer is D
I believe angles R and Q are corresponding, as well as angles P and S. The angles correspond with one another because the rings match up with one another. R and Q both have one ring, and P and S both have two rings.
Answer:
Step-by-step explanation:
The null hypothesis is usually the default statement while the alternative hypothesis is its opposite and usually tested against the null hypothesis.
In this case study, the null hypothesis is u = 21%/0.21, the percentage is not different among residents in Sonoma County and is equal to 0.21.
While the alternative hypothesis is u =/ 0.21, the percentage is different among residents in Sonoma County; not equal to 0.21
The answer is square root 6/2
