Answer:
a. 80km/hr
b. 8 dollars an hour
c. 30 passengers on one bus
d. 6 degrees a minute
Step-by-step explanation:
You want to divide these down to the smallest rate possible, so you divide.
480/6=80
80 km/hr
56/7=8
8 dollars and hour
270/9=30
30 passengers in one bus
54/9=6
6 degrees in one minute
Answer:
49°
Step-by-step explanation:
106 + 135 + 70 + x = 360
311 + x = 360
x = 49°
9514 1404 393
Answer:
x = ±3√2i
Step-by-step explanation:
Add -18 to both sides of the equation:
x^2 = -18
Take the square root of both sides:
x = ±√(-18)
Remember that 18=9·2 = (3^2)·2 and √-1 = i. Simplify.
x = ±(√(3^2))·(√2)·(√-1)
x = ±3√2i
