To be able to compete in a particular class, a bodybuilder can weigh in at no more than 175 pounds and no less than 145 pounds. If the clothes the wrestlers wear add 1
pound, what is the actual weight range, in pounds, for these bodybuilders (in interval
notation)?

B. [144, 174]

Step-by-step explanation:

Given

Total Weight Range = Not less than 145lb and Not more than 175lb

Required

Determine the actual weight range

Let x represent the total possible weight of a bodybuilder

From the question, we understand that the total weight is within the range of 145 to 175. i.e.

Also from the question, we understand that the bodybuilder's cloth adds 1 lb to the total weight;

The next step is to subtract this 1 lb from the range of total weight to get the actual weight range

This is as follows

This gives

From the list of given options, the correct answer is [144,174]

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
