Answer:
Lengths to be added are converted into cm.
15 m 18 cm = 1500 cm + 18 cm = 1518 cm
16 m 22 cm = 1600 cm + 22 cm = 1622 cm
Now, sum
1 1
1518 cm
+ 1622 cm
3140 cm
= 31 m 40 cm
Therefore, 15 m 18 cm + 16 m 22 cm = 31 m 40 cm

Law of Cosine
Answer: C = 2 + 0.25 D
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The cost of the cab ride (C), must be equal to the fixed fee (2) plus the product of the charge per mile (x) and the number of miles traveled (D)
C= 2 + Dx
Since the cost for a 50 mile ride is $14.50:
14.50 =2 + 50x
Solving for x:
14.50-2 = 50x
12.50 =50x
12.50/50 = x
0.25 = x
The cab company charges $0.25 per mile.
Back with the original equation:
C = 2 + 0.25 D

A=future amount
P=present amount
r=rate in decimal
t=time in years
n=how many tmes per year it is compounded
they want 110,000=A
present amount=?
rate is 6% or 0.06
time is 12 years
semianually means 2 times per year, so n=2
divide both sides by (1.03)^24 using your graphinc calculator
54112.7109=P
$54,112.71 should be invested
