where's the table??if you post the table I will help you
Let
x---------> the length side of rectangle
y---------> the width side of rectangle
we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2
28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m
the answer is
the length side of rectangle is 240 m
the width side of rectangle is 120 m
Answer:
y=3
-47.5
Step-by-step explanation:
I did it in my notebook.
Answer: h = (S - 2πr²) / 2πr
Step-by-step explanation:
Since we are given that
S = 2πrh + 2πr²
Subtracting by 2πr² on both sides we get
S - 2πr² = 2πrh
Dividing by 2πr on both sides we get
(S - 2πr²) / 2πr = h
So
The final equation is
h = (S - 2πr²) / 2πr
Let x be a random variable representing the mean saraly of professors at two year institutions, then
P(x > 55000) = 1 - P(z < (55000 - 52500)/4000) = 1 - P(z < 0.625) = 1 - 0.73401 = 0.26599
