Answer:

Ava needs to add 50ml of cleaner.

Step-by-step explanation:

Ratio of cleaner : water = 1:7

This means that the total ratio;(water+cleaner) = 1+7 = 8

Find fraction of each item out of the total ratio of 8;

Fraction of water = \frac{7}{8}

Fraction of cleaner = \frac{1}{8}

Knowing the fractions, find the quantity of cleaner in <em>ml </em>out of a total of 400-ml;

Cleaner = (1/8 )*400 = 50ml

Therefore, Ava needs to add 50ml of cleaner.

In imaginary numbers can you multiply two radicals that have negative values under them that do not square to whole numbers
ElenaW [278]
Yes, you can; based on the inherent assumption that the "two radicals that have negative values" are, in fact, "imaginary numbers" .

Take, for example, the commonly known "imaginary number":  "i" ;  which represents the "imaginary number" ;  " √-1 " .

Since:  "i = √-1" ; 

Note that:   " i² = (√-1)² = √-1 * √-1 = √(-1*-1) = √1 = 1 .
