Answer:
33 = r
Step-by-step explanation:
The circumference is given by
C = 2 * pi *r
207.24 = 2 * 3.14 *r
207.24 = 6.28 *r
Divide each side by 6.28
207.24/6.28 = 6.28 r /6.28
33 = r
Answer:
A.
x < -3/2 or x > 48/5
Step-by-step explanation:
12x + 7 < - 11
12x < -18
x < - 18/12
x < -3/2
Or
5x - 8 > 40
5x > 48
x > 48/5
Answer
x < -3/2 or x > 48/5
Answer:
0.83 mi/min
Step-by-step explanation:
Start with 80 km/hr. Convert this to the units miles/hr:
(80 km/hr)(1 mile/1.6 km) = 50 miles/hr
Next, apply the equality 60 min / 1 hr = 1 to 50 miles/hr:
50 miles. 1 hr
------------- * ------------ = 5/6 mi/min, or 0.83 mi/min
hr 60 min
