Answer:

45.3191

Step-by-step explanation:

0.0229 is 100 times smaller that 2.29 but 1979 is 100 times greater than 19.79. Since they cancel each other out, the answer remains the same.

Find the total travel time: Depart 5:30pm MST Arrive 9:20pm CST.
Alexus [3.1K]
2 hours and 50 minutes would be the answer. MST is one hour behind CST, so you would add an hour to 5:30 to basically make them the same time zone. Then you find the time between 9:20 and 6:30 to get 2 hours and 50 minutes.

A stone is an English measure of weight. There are 14 lb in 1 stone and 2.2 lb in 1 kg. A certain person weighs 9 stone.
USPshnik [31]
For every one stone it's 14lb and for every kg it's 2.2 lb therefore you would have to multiply 14 by 9 then divide that answer by 2.2 and that answer will be your answer..
14•9=126
126÷2.2=57.27
You would have 57.27kg or if rounded you would have 57kg

What is the answer for -7 x 7 please say the explanation too.
prisoha [69]

-7 x 7 = -49

We can first figure out 7 x 7, which will be 49. Once we have that, we can look at our negatives. If we have an odd number of negative signs, the answer will be negative. If we have an even number of negative signs, the answer will be positive. In this case, we only have 1 negative sign, and 1 is odd, therefore our answer will be odd.

ANSWER: -49

Hope this helps!
