Step-by-step explanation:
I beleve you answer is 10 because 3 time 10 equals 30 and the question sais "3 times longer"
Step-by-step explanation:
0.000000358 written as scientific notation is

X/50 = 20/100
its takes adding 30 to 20 to get to 50 so add 30 to 100 then its 130/100 (130 over 100) and then divide that and its 13 = 13%
i think its right dont hold it against me if im wrong
7.980 divide by 0.19 is 42.
