Answer:
11 feet
Step-by-step explanation:
Use the circumference formula, C = 
d
Plug in 11 as C, and solve for d:
C = d
11 = d
11 = d
So, the diameter is 11 feet
Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
y = x + 5 → (1)
x - 5y = - 9 → (2)
Substitute y = x + 5 into (2)
x - 5(x + 5) = - 9 ← distribute and simplify left side
x - 5x - 25 = - 9
- 4x - 25 = - 9 ( add 25 to both sides )
- 4x = 16 ( divide both sides by - 4 )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = - 4 + 5 = 1
Solution is (- 4, 1 )
Answer:
D=36
Step-by-step explanation:
All angles of the triangle add up to 180. Subtract 180-59-55=66
Then the missing measurement is a vertical which means that E=66.
So then 180-78-66=36
8-9r is the answer to this
