Answer:
64% or 16/25
Explanation:
To calculate probability, we first find the fraction for the number of books that are fiction.
To find out what the probability of choosing a fiction book twice, we multiply 4/5 with 4/5 to get our probability if we selected a book twice.
The probability of choosing two fiction books is a 16/25, or 64% chance.
I'm assuming you're comparing two triangles? If not, then this is probably wrong.
Triangle = 180 degrees
180 divided by 3 = 60 degrees
since ∠1 ≅ ∠2 ≅ ∠3, each angle equal 60 degrees
∠4 ≅ ∠5
m∠4 = m∠3 + 10
m∠3 + 10 = m∠5
we know that m∠3 is 60 degrees.
60 + 10 = 70, so m∠5 is 70 degrees
70 degrees is the answer.
How thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.
<h3>Density of the Neutron star</h3>
Density
ρ = m / V
Where:
ρ= density
m = mass of the planet 5.98 10²⁴ km
V =volume of the spherical layer
Volume of a sphere
Volume = 4/3 π r³
Mass = 1.5 = 1.5 1,991 10³⁰
Mass= 2.99 10³⁰ kg
Density:
ρ = 2.99 10³⁰ / [4/3 π (10 10³)³]
ρ is = 7.13 10 17 kg / m³
V = 5.98 10²⁴ / 7.13 10¹⁷
V = 8,387 10⁶ m³
Thickness of the layer
V = 4π r² e
e = V / 4π r
e = 8,387 10⁶ / [4π (10 10³)²]
e = 6.67 10⁻³ m
Inconclusion how thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.
