Acity planner is measuring the distance of one city block. which unit of measure should she use: 1 mile, 1 meter, 1/2 inch. explain.

Meters

Step-by-step explanation:

Miles are to big to measure the distance of a city block, and inches are too small.

If she were to use inches, the number of the measure would be too large, and not easy to imagine and of she were to use miles, it would be a  little number (like a fraction or decimal number), that wouldn't be as easy to understand. Instead, using meters, the measurements wouldn't be too little or to big, they would be between 50 or 150 meters on average, so these are numbers more usable and practical.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
