Shirley measures the thickness of a piece of cardboard with a ruler that has centimeter and inch markings. which of the following is most likely the value that shirley measures? a. 2.85 mm b. 3.0 in c. 0.118 in d. 3.0 mm

Hello there!

We know that the ruler has centimeter and inch markings.

First, analyze each option:

A: 2.85 mm

This is a really exact measure in mm, but the ruler has markings in centimeters, then you can divide each centimeter into 10 marks of 1 millimeter each, and you can measure millimeters with it, but you cant measure a 0.85 of a millimeter with it (maybe 0.5, but no more precise than that), then this measure is not possible to do whit this type of ruler

B = 3.0 inches

If the ruler has inches as units, this is a possible result in the lecture, but is a really thik cardboard piece, so is not likely to be the answer.

C: 0.118 inches

again, this is a very exact number, you can expect to have a lecture of 0.1 inches or 0.2 inches, but not one with that many significant numbers after the decimal point.

D: 3.0mm

This is equivalent to the A measure, but rounded up, is a less exact measure because you don't have significant numbers after the decimal point. Again, if you divide the centimeter into 10 marks, you can measure 2 mm or 3 mm (or 2,5 mm if you look in between both marks) but not a number as exact as 2.85mm, then this lecture makes more sense.

Then the possible answers are D and B, where B requires a really weird and thick piece of cardboard but is a possible measure.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
