Anna35 [415]

9ml will be given for the case of dosage calculation order: 3 mg available: 2 mg per 6 ml

dosage calculation techniques serve as a second or third check on the accuracy of the previous computation techniques. Dimensional Analysis, Ratio Proportion, and Formula or Desired Over Have Method are the three main approaches for dosage calculation. dosage calculations are frequently prescribed and labeled based on their weight or, for solutions, their strength, which is the amount of weight dissolved or suspended in a given volume.

Select the PREDICATE ADJECTIVE(S) (if one or more is present).
creativ13 [48]

<u>Answer:</u> There is no predicate adjective in the sentence.

<u>Explanation:</u>

Predicate adjective is defined as an adjective that follows the linking verb and modifies the subject of the linking verb.

For Example:

The shoes look expensive.

In this sentence, the shoes are the subject, 'look' is the linking verb and 'expensive' is the predicate adjective.

The predicate adjective modified the subject.

In the given sentence,

'Five' is a common noun, 'cookies' is the subject, 'are' is the helping verb, 'on' is the preposition, 'the' is an article and 'table' is a countable noun.

Hence, there is no linking verb and therefore, this sentence has no predicate adjective.
