Answer:
GPA ≈ 2.67
Step-by-step explanation:
Grade points are weighted by credit hours:
GPA = ∑(grade points×credit hours) / ∑(credit hours)
GPA = (3×2 +2×4 +4×3 +2×3)/(2 +4 +3 +3)
= (6 +8 +12 +6)/12 = 32/12 = 2 2/3
GPA ≈ 2.67
The sum for those numbers is 19.179 NOT 18.729. HOWEVER the Estimation of the sum and the answer for this question is 19.2 because the decimal place you are finding has a number to its right that is greater to that decimal place so you add the one to the decimal place you are finding.
Answer:
∠ b = 12°
Step-by-step explanation:
Complementary angles sum to 90°, thus
a + b = 90 ← substitute a = 78
78 + b = 90 ( subtract 78 from both sides )
b = 12
That is ∠ b = 12°
Answer:
Recall from Logarithm law Log a - Log b = Log (a/b)
so, Log 2 - Log 4 = Log ( 2/4)
= Log ( 1/2).
Also from the law
Log (a/b) = Log a - Log b
i.e Log (1/2) = Log 1 - Log 2
Recall: Log 1 = 0
which implies : Log 1 - Log 2 = 0 - Log 2
= - Log 2
