Which of these rules is applicable to subtracting two values that have different numbers of decimal places (for example, subtracting 2.1 from 2.15)? the answer is less accurate than either value. the answer is more precise than either value. the answer has the same number of decimal places as the least precise value. the answer has the same number of significant figures as the most precise value.

The answer has the same number of decimal places as the least precise value.  

Step-by-step explanation:

We know that in subtraction, the important thing is the decimal place occupied by the last significant figure.

When we subtract two values having different number of decimal values, the resulting answer can have number of decimal places less than or equal to the number of decimal places in every term.

For e.g. 2.15 - 2.1 = 0.05 and 7.96-7.2 = 0.76

Hence, option C i.e.'the answer has the same number of decimal places as the least precise value' is correct.

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
