Explain why 0.25x0.4 has only one decimal place in the product.

0.1 is the answer of that equation but 0.1 can also be written as 0.100 or 0.10000 or and amount of zero just when you have zeros in the decimal places you usally dont count them so 0.100 is the same as 0.1 the same would also call for somthing like 0.40000 it can be written as 0.4 instead.

answer: -8.2562234e+13

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
