The scale factor of an object is the ratio of the lengths of two corresponding sides of two similar objects. True

False

True

Step-by-step explanation:

If there are 2 similar geometric figure the ratio of the corresponding side length is regarded as the scale factor. For example if you have 2 similar  figure like a  square. And you detect 2 corresponding sides of the figures , one having a length of 2 cm and the other a length of 4 cm. The ratio of this 2 corresponding side is the scale factor . The scale factor can be express as 1:2. or the scale factor can be represented as a fraction as 1/2.

In a more simple term the scale factor is the ratio of 2 corresponding side of similar figures. Note the figures must be similar . The scale factor can be use to find the side length of a figure and also one can use the side length of the figures to find the scale factor.

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
