230% of some number is 48.2. What is the number? The number is 46
The time changes depending on how fast the truck is going-so it's dependent
50 miles and the truck do not change no matter what-so they are constant
The speed of the truck changes the time-so the speed is the independent
<u>Answer:</u>
The correct answer option is 
.
<u>Step-by-step explanation:</u>
We are given the following expression and we are to figure out which of the given answer options show the expression after the negative exponents have been eliminated:
When negative exponent changes sign, then it moves from numerator to denominator or from denominator to numerator.
Irfan must walk a distance of <u>25</u> blocks <u>east</u> to return to his apartment building.
<h3>What is a compass?</h3>
A compass can be defined as a scientific instrument that contains a magnetized pointer, which is used to show and indicate the following four (4) main cardinal directions:
<h3>What is distance?</h3>
Distance can be defined as the amount of ground covered (traveled) by a physical object over a specific period of time and speed, regardless of its direction, starting point or ending point.
Next, we would calculate the total distance covered (traveled) by Irfan as follows:
Total distance = 20 + 5
Total distance = 25 blocks.
Since Irfan walked a total distance of 25 blocks west, he would have to walk the same distance in the opposite direction (east) to return to his apartment building.
