An ant weighs 2 x 10^-3 grams, and a lion weighs 1 x 10^5. the lion's weight is 5 x 10^x times greater than the ant's weight. what is the value of x?

x = ?

x=7

Step-by-step explanation:

Information provided

Weight of ant=

Weight of lion= but units are not provided, assuming this unit is also grams

How many times lion's weight exceed an ant

=

Therefore, the value of x=7 if the unit for weight of lion is assumed to be same as unit for weight of an ant

answer: -1

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
