First change the fraction to a decimal by multiplying both sides by 2. 49 times is 98. Therefore, you have to put it as 0.98. Now you put the 686 in place of the 0. The final answer is 696.98.
The circumference is 2.720984 million mi
Answer:
4.3
Step-by-step explanation:
mean=sum of the terms/number of term
room A=3+20+25+0+0+0=25
Room B= 2+18+4+0+0+0=24
room C= 28
room D= 21
room E= 32
step(2)
25+24+28+21+31=130/30
= 4.3
Not really subtract, I would say divid the number they share from it, so 2/4 you can divide each by 2 to make it 1/2. Hope this helped!
