Answer:
Step-by-step explanation:
In 10 seconds -radius is 0.5 inches
in y seconds - radius is 1.25 inches
now using cross multiplication method
10 x 1.25 =0.5 x y
y= (10 x 1.25)/0.5
y = 25 seconds
hailstone should be 25 seconds long in the cloud to have a radius of 1.25 inches.
Answer:
(Infinitely), (No solution), (One solution), (One solution)
Step-by-step explanation:
1. 5x + 9 = 9 + 5x (Infinitely)
2. -4x + 8 = -4x - 8 [minus -4x from both equation, we get 8 = -8, which is impossible] (No solution)
3. x - 3 = 3 - x [2x = 6, x = 3] (One solution)
4. 3x + 7 = 7x + 3 [4x = 4, x = 1] (One solution)
