A 5/16 inch bolt weighs 0.43 lb. How many bolts are there in a 125 lb. keg?

290 Bolts are There

Step-by-step explanation:

5/16 bolt Here 5/16 is size of Bolt

1 bolt Weighs  of given size weighs = 0.43 lb

Total Weight = 125 lb

Number of Bolts in Bag  = Total Weight of Bag / Weight of 1 Bolt

= 125/0.43

= 290

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
