Angle 2 is also 122 because angles that are across from eachother (vertical angles) are always equal.
Correct answer= A
Answer:
1 hour and 30 minutes.
Here's how I did it:
960/3 = 220
220 = 30 minutes
220 = 30 minutes x 3 = 960
30x3=90
90 has to be converted into minutes and hours
so 90 = 1:30
Answer:
c and f
Step-by-step explanation:
7.1 years
Step-by-step explanation:
Principle P = 9000 dollars
Rate r = 4.75% = 0.0475
Total Amount A = 12600 dollars
compounded quarterly n = 4
Time t = ?
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(12,600/9,000) / ( 4 × [ln(1 + 0.011875/4)] )
t = 7.1 years
so the answer is 7.1 years
