Answer:
HUH WHAT DOES THIS MEAN?
Step-by-step explanation:
Since C = 2rπ
if the C of earth = 25000 miles
then the r = C ÷ (2π)
= 25,000 miles ÷ 2π
= 12500 ÷ π
≈ 3978.87358 miles
Since radius is a measure of the distance from the center to any point on the circle then that distance would be about 3978.8736 miles<span />
Answer:
4/5 is fully reduced
Step-by-step explanation:
Y=1/2x -3 find the x coordinate of the point whose y
coordinate is 5
y = 5. Write the equation as:
1/2F2x - 3 = 5
multiply both sides by 2, and you have
x - 6 = 10
x = 10 + 6
x - 16
Check solution in original equation, replace x with 16
y = 1/2F2(16) - 3
y = 8 - 3
y = 5
