Answer:
32.8 miles
Step-by-step explanation:
Amy is driving to Seattle. Suppose that the remaining distance to drive (in miles) is a linear function of her driving time (in minutes). When graphed, the function gives a line with a slope of -0.95. See the figure below. Amy has 48 miles remaining after 31 minutes of driving. How many miles will be remaining after 47 minutes of driving?
Answer: The general equation of a line is given as y = mx + c, where m is the slope of the line and c is the intercept on the y axis. Given that the slope is -0.95, substituting in the general equation :
y = -0.95x + c
Amy has 48 miles remaining after 31 minutes of driving, to find c, we substitute y = 48 and x = 31. Therefore:
48 = -0.95(31) + c
c = 48 + 0.95(31)
c = 48 + 29.45
c = 77.45
The equation of the line is
y = -0.95x + 77.45
After 47 minutes of driving, the miles remaining can be gotten by substituting x = 47 and finding y.
y = -0.95(47) + 77.45
y = -44.65 + 77.45
y = 32.8 miles
Answer:
Step-by-step explanation:
Exponents are basically just saying how many times the number is multiplied by itself.
In the expression 
, we can see that 10 is being multiplied by itself 5 times.
So the exponent becomes 5, and the base is 10.

Answer:
616/2500
Step-by-step explanation: You first have to find the number of times a Blue marbles was chosen: 22
Then find the total number of marbles that were chosen. Make a fraction out of it: 22/50
You then see how many times tails was flipped: 28
Do the same thing again: 28/50
Then multiply the two fractions together:
22/50 * 28/50 = 616/2500
