The answer is 780 feet.
There is 5,280 feet in a mile. If the kangaroo jumps 30 feet 150 times, it will have gone 4,500 feet. So the kangaroo will need to go 780 feet to make a mile.
Formula: 5,280-4,500=780
To mountains took 9 Hrs at x mph where x = No of miles to mountains
No of miles travelled = 9x
From mountains took 4 hours at (x+40) mph
No of miles travelled = 4(x+40)
Therefore 9x=4(x+40) thus 9x=4x+160 thus x=32 = distance Charmaine lives from the mountains

Answer:</h2><h2>Yes, the simplified form of 2 square root of 3 − 2 square root of 3 is rational.</h2>
Step-by-step explanation:
The given expression is 
After performing the subtraction operation, the result is 0 as the terms are equal and opposite in sign, they cancel each other.
Rational numbers are those which can be expressed in the form of fractions, decimals, e.t.c
Since 0 can be expressed as a fraction, it is a rational number.
For eg:
= 0,
Hence the result of the given expression is a rational number.
What are you trying to say here i mean yes it could be true if you divide it by 2 or 1.
