26 x π = circumference
81.6814 = circumference
2700/81.6814 = 33.6855 inches per minute
Convert to miles per hour by multiplying by (12 x 5280 x 60)
33.6855 x 12 x 5280 x 60 = Miles per hour

Rational Numbers: Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. ... So, any terminating decimal is a rational number.
Answer:
x = 17
Step-by-step explanation:
These are same side interior so they equal different measures. You would write the equation like this.
8x - 9 + 53 = 180 (collect like terms)
8x + 44 = 180 (minus 44 on both sides)
8x = 136 (divide by 8 on both sides)
x = 17

Answer:
B
Step-by-step explanation:
Answer: 90,75. cos 55°. sin55° ≈ 42,64
through E, draw EK perpendicular to BC (F ∈ BC)
because E is the midpoint of AB => BE = 11/2 = 5.5
ΔBEF is a right triangle at K
=> sin 55° = EK/BE
=> EK = 5,5.sin 55°
ΔABC has E and F is the midpoints of AB and AC
=> EF is the median line of the triangle
=> EF = 1/2.BC
through A, draw AD perpendicular to BC
=> ΔABD is a right triangle at D
=> BC = 11.cos 55°.2 = 22.cos 55°
=> EF = 11.cos 55°
=>the area of the trapezium BEFC is:
