A chemical company makes two brands of antifreeze. The first brand is \( 20 \% \) pure antifreeze, and the second brand is \( 70 \% \) pure antifreeze. In order to obtain \( 30 \) gallons of a mixture that contains \( 65 \% \) pure antifreeze, how many gallons of each brand of antifreeze must be used?
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
\( 8,40,200 , \ldots \)
Find the \( 10 \) th term.
(1) q) Put \( S \) above any dash that represents subtraction, \( N \) above any dash that represents negative and \( O \) above any dash that represents opposite. NOTE: You only need to give one answer if more than one answer is possible for a dash.
\( - ( 2 - ( - 3 ) ) - ( - 4 + ( - 2 ) ) + 4 ( - 5 ) + ( - ( - 3 ) )\)
