1 km = 0.621371 miles
5 km = 5 x 0.621371 = 3.106855 miles
round off as needed.
1.0649 to the nearest thousandths is 1.065
You could get this by finding where the thousandths place is, which is the third number.
Now, look at the number to the right.
If it's 5 or higher, round up.
If it's 4 or lower, round down.
Since it is 9, we round up.
The 4 turns into a 5.
So, 1.065
Hope I helped!
The <em><u>correct answers</u></em> are:
The inequality is 75+4t ≥ 400, and they must sell at least 82 tickets.
Explanation:
t is the number of tickets sold. They start out with $75, so that is where our inequality begins. Each ticket is $4; this gives us the expression 4t. Together with the $75 carry over, we have 75+4t.
They must make at least $400 to pay for the dance. This means it must be more than or equal to 400; this gives us 75+4t ≥ 400.
To solve this, first subtract 75 from each side:
75+4t-75 ≥ 400-75
4t ≥ 325
Divide both sides by 4:
4t/4 ≥ 325/4
t ≥ 81.25
We cannot sell a portion of a ticket, so we round. While mathematically this number would "round down," if they only sell 81 tickets, they will not have enough money. Therefore we round up to 82.
So it would be x12 to the 2nd power, kinda hard to explain but i really hope this helped
The answer is : impossible
