Average is
(2x + X+6)/3=63
(2x+x+6)= 189
3x+6=189
3x=183 61
X=61
Scores for the game are: 61, 61, and 67
Answer:
48
Step-by-step explanation:
<span>a.
The radius of earth is about 6400 kilometers. Find the circumference of
a great circle.
Circumference = 2π(radius) = 2π(6400 km) = 40.212,39 km
b. Write an equation for the circumference of any
latitude circle with angle theta
As stated, </span><span><span>the
length of any parallel of latitude (this is the circumference of corresponding circle) is equal to the circumference of a
great circle of Earth times the cosine of the latitude angle</span>:
=> Circumference = 2π*radius* cos(Θ) = 2 π*6400km*cos(Θ) = 40,212.39 cos(Θ)
Answer: circumference = 40,212.39 cos(Θ) km
c. Which latitude circle has a
circumference of about 3593 kilometers?
Make </span><span><span>40,212.39 cos(Θ)</span> km = 3593 km
=> cos(Θ) = 3593 / 40,212.39 = 0.08935 => Θ = arccos(0.08935) = 84.5° = 1.48 rad
Answer: 1.48
d. What is the circumference of
the Equator?
</span>
For the Equator Θ = 0°
=> circumference = 40,213.49cos(0°) km = 40,212.49 km
Answer: 40,212.49 km
17.92
∧ ∧ this is the ones place
this is the tens place
if the ones place is lower then 5 you keep the tens the same. if the ones place is higher then 5 you round the tens place up one. so the answer is 17.90
Answer:
X=0
Step-by-step explanation:
4x=0
divide both sides by 4
x=0/4
x=0
