Answer:
∠2 = 41°
Step-by-step explanation:
∠2 + 49° + 90° = 180°
∠2 + 139° = 180°
∠2 = 180° - 139°
∠2 = 41°
To convert a mixed fraction into an improper fraction, we must follow some steps.
First, we take the whole part and multiply it by the denominator of the fraction.
In this case, we take 2 and multiply it by 8.
Now we add the numerator:
16+3=19
The denominator stays the same:

4/5 a mile
2/10 time 10=20/100
20/100+ 60/100=80/100 or 4/5
Answer:
≈ 16 g
Step-by-step explanation:
Half life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half of its initial mass.
Therefore;
New mass = Original mass × (1/2)^n, where n is the number of half lives
Thus;
New mass = 125 × (1/2)³
= 125/8
= 15.625
≈ 16 g
Your answer in the sum is 0.26
