Answer:
x = 12
Step-by-step explanation:
6 (x - 10)= 3 (x - 8)
6x - 60 = 3x - 24
6x - 3x = 60 - 24
3x = 36
x = 36/3
x = 12
For first question, you can let t=1.5 and calculate h=140 ft. For second question, we can change the equation to the form of h=-16[(t-2)^2-9]. So you can see from the equation that the maximum height is created when t=2, equals to 144 ft. For question 3, let h=128. From equation, we can get t=3 or t=1. For last question, the rocket hit the lake means h=0, so t=5 or t=-1(not applicable). So the answer is t=5. You can also draw the graphic for the equation to help.
Answer: 0.25 feet
Step-by-step explanation:
Given: Jonathon has paper strips that are all equal in length.
Let x be the length of each paper strip.
Since John lines them up end to end, the length of the line of paper strips= 3 feet
Also total strips used= 12
Therefore, length of line of strips=

hence, if Jonathan is correct then the length of each strip will be 0.25 feet.
