n a science experiment, farah mixed a salt solution and
vinegar in the ratio 3 : 7.
A.) if she used 262.8 milliliters of salt solution, the
amount of vinegar is equal to:
X = 262.8 ml ( 7 ml vinegar/ 3 ml salt soln)
X = 613.2 ml vinergar
B.) y = 0.56 L vinegar ( 3 L salt soln/ 7 L vinegar)
Y = 0.24 L salt soln
Rewrite
(4)(3.63) * (10^4)(10^-4)
multiply
14.52 * (10^4)(10^-4)
multiplication of the coefficient is the addition of the exponent
so 4 -4 is 0
14.52
Hope this helps :)
