Answer:
C. One-fourth mile over thirty-six seconds = 25 miles per hour.
We have been given that an elephant can run one over four of a mile in 36 seconds.
To find elephant's rate in miles per hour, we will convert our given time in hours as shown below:
Therefore, option C is the correct choice.
Step-by-step explanation:
Two solutions:
1. x =(100-√2160)/2=50-6√ 15 = 26.762
2. x =(100+√2160)/2=50+6√ 15 = 73.238

Answer:
C) (14, 8, 10)
Step-by-step explanation:
the values in the parentheses go in order of the letters in the first equation
all you have to do is plug in the values
p+q+r=32. (14)+(8)+(10)=32
p-r=4. (14)-(10)=4
2p+q=36. 2(14)+(8)=36
