Convert the following measurements. a. 90 kilometers to meters b. 250 centimeters to hectometers c. 3,500 millimeters to dekameters d. 10 dekameters to decimeters

Answer with explanation:

We have to make the following conversions:

a)

90 kilometers to meters.

We know that 1 kilometer=1000 meters.

Hence,

90 kilometers=90000 meters.

b)

250 centimeters to hectometers.

We know that:

1 centimeter=0.0001 hectometers.

Hence, 250 centimeter=0.0250 hectometer.

c)

3500 millimeters to decameters.

1 millimeter=0.01 decimeter.

and 1 decimeter=0.01 decameter.

Hence,

3500 millimeter=0.35 decameter.

d)

10 dekameters to decimeters.

We know that:

1 decameter=100 decimeters.

Hence,

10 decameter=1000 decimeter.

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.
