If it takes 30 steps to walk from the front of the store to the back and 40 steps to walk from the left of the store to the right how many steps would it take to walk diagonally across the store

70

Step-by-step explanation:

The answer is 70 steps, because you walked 30 steps from the front to the store then you walk to the left of the store, you now can add these together to make 70 steps altogethor! how this helps!

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
