Answer:
4/16 ( 1 + 11) = 3
could be many answers as fractions see below
The last fraction seems more likely out the three or make it harder fraction.
Step-by-step explanation:
1/2 (2 + 4) = 3 as 1/2 of 4 is 2 1+2 = 3
or
1/4 (4 + 8) = 3 as 1/4 of 8 is 2 1+2 = 3
or
3/4 ( 2 + 2) = 3 as 3/4 of 2 is 1 1/2 1.5 + 1.5 = 3
or harder fraction
4/16 ( 1 + 11) = 3
Answer:
4 sqrt(3) =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 60 = x / 8
8 sin 60 = x
8 ( sqrt(3)/2) = x
4 sqrt(3) =x
<span>(100 km/hour) x (1,000 m/km) x (1
hour/3600 sec) = 27 and 7/9 meters per sec.
If you round the
number, it could become approximately 27.8 or even 28 .</span>

Answer:
a. d = C/π
b. d = 8/π inches ≈ 2.546 inches
c. r = 61/(2π) inches ≈ 9.708 inches
Step-by-step explanation:
a. The formula for circumference is ...
C = πd
Dividing by π gives ...
d = C/π
__
b. For a circumference of 8 inches, the diameter is ...
d = (8 in)/π = (8/π) in ≈ 2.546 in
__
c. The radius is 1/2 the diameter. So, the radius of a circle is ...
r = d/2 = (C/π)/2 = C/(2π)
For a circumference of 61 inches, the radius is ...
r = (61 in)/(2π) = 61/(2π) in ≈ 9.708 in
