Inequality: 22 + 5x ≥ 59
Minimum amount: 7.4
Realistic number: 8
Represented on a graph: I think it would look like a vertical line starting at the x value of 8, and continue right forever
Step-by-step explanation:
22 because that's how much she has already, 5x will represent her earnings relative to the number of driveways she pressure washes, and greater than or equal to 59 because she needs $59 or more to buy the video game.
22 + 5x ≥ 59 (subtract 22 from each side)
5x ≥ 37 (divide each side by 5)
x ≥ 7.4
Answer:
Hailstone remained in the cloud for 25 seconds.
Step-by-step explanation:
Radius of a hailstone varies directly with the duration for which it was in the cloud.
Let the radius of the hailstone is 'r' and it was in the cloud for 't' seconds.
r ∝ t
r = kt [ k is the proportionality constant]
If r = 0.5 inches and t = 10 seconds
Then, 0.5 = k × 10
k =
k = 0.05
Now we have to find the duration t for which hailstone was in the cloud having radius = 1.25 inches.
1.25 = 0.05 × t
t =
t = 25 second
Therefore, hailstone remained in the cloud for 25 seconds.
