Answer:
266
Step-by-step explanation:
There are (3 ft)^3 = 27 ft^3 in 1 cubic yard. Then 9.83 cubic yards will be ...
(9.83 yd^3)(27 ft^3/yd^3) = 265.41 ft^3
265 sacks will not be enough. 266 sacks must be ordered.
For this you have to do sin of 30 degrees so if you have a calculator put sin(30)= a/44 and solve for a

Step-by-step explanation:
Answer:
Two buses leave towns 760 mi apart at the same time and travel toward each other. One bus travels
18 mi/h slower than the other. If they meet in
5 hours, what is the rate of each bus?
~~~~~~~~~~~~~~~~
Let x be the rate of the slower bus, in miles per hour.
Then the rate of the faster bus is (x+18) mph, according to the condition.
The slower bus covered 5x miles before the buses meet each other.
The faster bus covered 5*(x+18) miles before they meet each other.
The sum of distances covered by buses is 3x + 5*(x+18).
It is equal exactly 760 miles. It gives you an equation
5x + 5(x+18) = 760.
Simplify and solve for x:
5x + 5x + 90 = 760,
10x = 760 - 90,
10x = 670 ====> x = 670%2F10 = 67.
Thus you found the rate of the slower bus. It is 67 miles per hour.
Then the rate of the faster bus is 67 + 18 = 85 mph.
Solved.
