Answer:
The time taken by the driver is: t = 1.6 seconds
Step-by-step explanation:
Given
Distance covered by a race car = d = 300 mile
Speed of a car = s = 183.2 mph
To determine
The time of the driver = t = ?
Using the formula to determine the time of the driver
distance = speed x time
d = st
t = d/s
substitute d = 300 and s = 183.2
t = 300 / 183.2
t = 1.6 seconds
Therefore, the time taken by the driver is: t = 1.6 seconds

Call x the smallest of the three numbers, then:
x + (x+1) +(x+2) = -27
x + x + 1 + x + 2 = -27
3x+3 =-27
3x = -27 -3
3x = -30
x = -30/3 = -10
The three numbers are: -10, -9 and -8.
Answer:
x-intercept is 10. It means when you buy 10 cups of coffee you run out of money
Step-by-step explanation:
The x-intercept happens when y = 0
so
0 = 20 - 2x
solving for x we get
2x = 20
x = 10
so when you buy 10 cups of coffee you run out of money
