Answer:
It is 50 cm squared hxb/2=a
I think the answer is .4m^7n^8
Uhh I don’t know how to give it a clear explanation but all I did was multiply them
-0.8•-0.5= .4
M^2•m^5=m^7
n•n^7=n^8
Hope this helps some.
9 feet and 1 inch is your answer
6 then thousandths=60,000
1 more thousandth then 10,000=11,000
No hundreths=000
3 more tens then 10,000=40,000
And 4 fewer ones than 10,000=9,996
Add that all together and you get 121, 996
Percent decrease=decrease/original times 100
decreas=860-790=70
original=860
percent decrease=70/860 times 100
percent decrease=0.0813953 times 100
percent decrease=8.13953
about 8%
