Answer: 12.8
Step-by-step explanation:
Divide 80.5 by pi then divide by 2
First arrange the numbers from least to greatest:
67, 76, 76, 82, 84, 93
The median is the middle number. But since we have two numbers that are in the middle we have to find the average of them.
76 + 82 = 158
158/2 = 79
So your answer is 79
Answer:
(23, 4)
Step-by-step explanation:
If we use substitution, we need to rewrite the 2nd equation so we can substitute it into the first.
Step 1: Rewrite 2nd equation
x = 5y + 3
Step 2: Substitution
2(5y + 3) - 5y = 26
Step 3: Distribute
10y + 6 - 5y = 26
Step 4: Combine like terms
5y + 6 = 26
Step 5: Isolate <em>y</em>
5y = 20
y = 4
Step 6: Find <em>x</em>
x - 5(4) = 3
x - 20 = 3
x = 23
And we have our final answer!
28.26 feet squared
Work:
A = π r²
A = 3.14 (3²)
A = 3.14 (9)
A = 28.26
