Parallel lines have the exact same slope ( or else they would eventually run into each other). So the answer is -1/2 is the slope.
What your going to want to do is take graph paper each square is five feet draw whatever shape your room is on it and take perimeter and area I cant write the reflection as I don't know what room you have drawn.
To determine how many times larger the peach got, you will divide the new diameter by the original diameter length.
188869/98 = 1927.2
The new diameter is approximately 1927 times longer.
To convert this to scientific notation, move the decimal point from the end (on the right) to between the 1 and the 9 to get 1.927.
Then count the number of decimal places you moved to get there, because this represents how many groups of 10 you adjusted your place value by and then becomes your exponent in scientific notation.
1.927 x 10^3 times is the answer in scientific notation.
so, is a semi-circle, half a circle, recall a circle has a total of 360°, so half of that will be 180°.
the diameter of that circle is 10, so its radius is half that, or 5.

Five out of ten or 1/2 depends if it is a 6-numbered die.
