Answer:
r = 7.3 m
Step-by-step explanation:
A = (pi)(radius)^2, so, if A = 167 m^2, r^2 is found as follows:
167 m^2
r^2 = -------------- = 53.158 m^2
3.14
Taking the square root of both sides, we get
r = 7.3 m
This is correct, because A = (pi)(radius)^2 becomes (3.14)(7.3 m)^2 = 167.4 m^2
To answer this question you first have to find angle acb. You’ll take the sum of the triangle and plug it into an equation. 180=65+(4x+5). You combine like terms and then divide the 4 to both sides to get 27.5. Then you do the same thing to find bcd. 180=27.5+9x-5. Which is 17.1667. I hope that helps!

Answer:
<h2><u><em>
x = - 14</em></u></h2>
Step-by-step explanation:
-3x – 10 = 32 Help me I need the answer
-3x – 10 = 32
-3x = 32 + 10
-3x = 42
x = 42 :(-3)
x = - 14
-----------------
check
-3 × (-14) - 10 = 32 (remember pemdas)
42 - 10 = 32
32 = 32
the answer is good
Answer:
The mean of the measurements is 91.17.
Step-by-step explanation:
The mean is the sum of all measurements divided by the number of measurements.
For this problem, we have that:
The sum of all 100 measurements was 9117.0.
So, the sum of all measurements is 9117.
The number of measurements is 100.
So:
The mean of the measurements is 91.17.
