a compound of two chemicals is mixed in the ratio of 3:10. If there are 45 liters of the compound, how much of each chemical is in the compound?

A 60m steel pole is cut back into 2 areas, in the ratio 11:4. at first, you upload the figures in the ratio, 11 and four, to be sure what the linked fee of one section equals. 11 + 4 = 15 60/15 = 4. So one section equals 4m. Substituting this back into the ratio, 11(4):4(4) 44m:16m The longer pole is 44m and the shorter one is 16m. the version between the two is 40 4 - sixteen = 28m The longer one is 28m longer than the shorter one. desire that helps. =D

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
