Answer:
23.9
Step-by-step explanation:
His route from school to Rhianna's house to his house forms a triangle in which the sides are 7 miles and the hypotenuse is unknown. Solving using the Pythagorean theorem, we find the route from Rhianna's house back home is 7^2+7^2=x^2.
Rounding to the nearest tenth, we now know this route is 9.9 miles. Adding the total distances from each location, we get an answer of 7 + 7 + 9.9 = 23.9.
I will have to assume that you actually meant " e^(ln 7x). The exponential and logarithmic functions are inverses of each other, so d^(ln 7x) = 7x (answer C).
48:64
3+4 = 7
112/7 = 16
16 * 3 = 48
16 * 4 = 64

Step-by-step explanation:
In order to get from 8 to 56, we have to multiply by 7.
We always do the same to the top! 3 multiplied by 7 = 21.
In order to get from 7 to 56, we have to multiply by 8.
We always do the same to the top! 3 multiplied by 8 = 24.

Answer: 33%</h3>
===========================================================
Explanation:
1/3 converts to the decimal form 0.333333... where the 3's go on forever
5/3 is a similar story but 5/3 = 1.666666.... where the '6's go on forever
The notation
indicates that the 6's go on forever.
So, 
The horizontal bar tells us which digits repeat. As another example, 
The three dots just mean "keep this pattern going forever".
----------
Everything mentioned so far has the decimal portions go on forever repeating some pattern over and over.
The only one that doesn't do this is 33% which converts to the decimal form 0.33
The value 0.33 is considered a terminating decimal since "terminate" means "stop". So this is the value that doesn't fit in with the other three items mentioned.
