Both are
indicators of the chemical composition of silicate minerals, magmas and rocks.
Mafic is
used for silicate minerals, magmas and rocks that are composed of heavier
elements, like magnesium, iron, calcium and sodium. They are dark and have high
specific gravities.
<span>Opposite to
the this, felsic silicate minerals, magmas and rocks in their composition have
less from these heavy elements. They are composed from silicon, oxygen,
aluminium and potassium, are light in color and have lower specific gravities.</span>
Answer: true
Explanation:
Angle A is 150
Angle B is 30
Supplementary= 180, so....
Angle A + Angle B = 180
150 + 30= 180
hope this helps
If n>4, then n+3<2n<3n-2 (n+3<2n is true because this unequality is equivalent to 3<n and 2n<3n-2 is also true because this unequality is equivalent to 2<n). Hence, the side AC is the smallest one and the side AB is the biggest one.
The largest side is opposite the largest angle, the medium side is opposite the medium angle and the smallest side is opposite the smallest angle.
Then, m∠B<m∠A<m∠C.
Answer: m∠B<m∠A<m∠C.
Answer:
2/5
Step-by-step explanation:
3/5 / 2/3
3/5 ÷ 2/3
Convert ÷ sign into multiplication, that will turn 2/3 into 3/2
3/5 X 2/3
Divide by 3
3/5 by 3
1/5
2/3 by 3
2/1
1/5 X 2/1
2/5
