The answer to your question is 46.9
Answer:
n=7
Step-by-step explanation:
(7^2)^4= n^8
We know that a^b^c = a^(b*c)
7^(2*4) = n^8
7^8 = n^8
Since the exponents are the same, the bases must be the same
n=7
Answer:
672 revolutions.
Step-by-step explanation:
Let n represent number of revolutions.
We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.
We know that 1 mile equals to 63360 inches.
We will use circumference of circle formula to solve our given problem.
, where, D represents diameter of circle.
Now, we will set the product of n and circumference of circle equal to 63360 inches as:
Therefore, it will take 672 revolutions for the wheel of car to travel a distance of one mile.
8 2/3 - 7 3/4= X
8 ?/12- 7 ?/12=X
8 8/12- 7 9/12
104/12- 93/12
104/12-93/12=11/12
7 3/4+11/12=8 2/3
X=11/12
