Answer:
i think the answer is c
Step-by-step explanation:
5445 = 4500 i * 7
5445 = 31500i
i = 5445/31,500
i = 0.1729
i = 17.29%
Answer:
55mph
Step-by-step explanation:
car A distance, d1= 220
car b distance, d2= 260
speed of car A, s1= speed of car B- 10
let speed of car B be s2
s1= s2-10
speed = distance/time
time= distance/speed
As time of car A= time of car B
distance of Car A/speed of Car A=distance of Car B/speed of Car B
220/s2-10= 260/s2
s2=(s2-10)260/220
s2=65
s1= s2- 10
= 65-10
=55
hence speed of first car is 55mph !
Step-by-step explanation:
if I understand correctly, then he bought a CD with a balance of c and an annual interest rate of 6%.
now, after this one year the CD is worth (the account balance is) c + 6% = 100% + 6% = 106% = 1.06×c
