I think you're talking about the black spot on the surface of the Earth,
where the end of the Moon's shadow falls, and anybody inside that
circle sees the Sun completely covered for a few minutes.
The size of that spot varies. It depends on exactly how far the Moon
is from the Earth, and exactly how far both bodies are from the Sun.
The longest possible totality viewed from a single location is about
7-1/2 minutes, when all the geometry is just right. Then, I believe,
the black spot on the Earth's surface is something like 170 miles
across, moving at around 24 miles a minute, or 1,460 miles per hour.
I think it’s A Im not sure tho
Answer:
shirts are $32 each and hats are $18 each
Step-by-step explanation:
x = shirts
y = hats
2x + 5y = 154
3x + 4y = 168
use either substitution or elimination
x = $32
y = $18
Answer:
{-3, 3}
Step-by-step explanation:
x^2 - 9 = 0 can be written in factored form as (x -3)(x + 3) = 0. Letting each factor equal zero separately and solving for x, we get x: {-3, 3}
.5 equals one half.
8 is 8 over one (8/1)
8 + 1/2 = 8 1/2
To make it an improper fraction multiply the denominator (bottom number) by the whole number and add the numerator (top). 8*2=16+1=17
Then, put this number over the existing denominator. 17/2
