The first three are functions
Step-by-step explanation:
4th one fails the Vertical line test.
5.0 x 10^6 X 473 = 2.4 x 10^9
There are 5 x 10^6 blood cells in a ml, and 473 ml in a pint. simply multiply both numbers together and put the answer in scientific notation (one digit before the decimal)
The bill total would be $140 because there are seven people (6 friends+Jacob) and each payed $20. (7)(20)

Answer:
4 km per hour and 6 km per hour.
Step-by-step explanation:
The combined running rate = 30/3 = 10 km/h.
If one runner's speed = x then the other one's speed is x+2 km/h.
So x + x + 2 = 10
2x = 8
x = 4
So one runs at 4 km/h and the other at 6 km/h.
