The 250m between Sam's house and the tennis court corresponds to 5 cm on a town map. What is the actual distance between Sam's school and the library if they are 8.4 cm apart on the same map? Plz answer in meters, thanks!

420 m

Step-by-step explanation:

250m >>> 5cm

Everything must be of the same unit so 250 x 100 =25000 cm

If The distance between the school and the library is 8.4 then,

25000 >>> 5

?? >>> 8.4

We do cross multiplication

(25000 x 8.4) ÷ 5 = 42000cm

42000 ÷ 100 = 420 m

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

it is true
