Answer:
The patient should receive 460mg of the drug
Step-by-step explanation
This problem can be explained as a simple rule of three.In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.
In this problem, the measures are:
- The dose of the drug
- The weight of the patient.
As the the weight of the patient increases, so will the dose of the drug. This means that the relationship between the measures is direct, and we have the following rule of three:
20 mg - 1 kg
x mg - 23kg
x = 20*23
x = 460mg
The patient should receive 460mg of the drug
The answer
$50 +$1=$51
so $<span>51-$0.72=$50.28
the taxe rate is 7.5%
it is </span><span>$50.28x7.5/100= $3.77
</span>
the selling price of the blender before taxes was $50.28 - <span>$3.77=$46.50</span>
Answer:
The molecular or chemical formula of Lithium Bromide is LiBr. Lithium Monobromide is synthesized by treating lithium carbonate (Li2CO3) with hydrobromic acid (HBr). The salt forms cubic crystals which are similar to sodium chloride.

Answer:
Equation: $1.67n=C
Step-by-step explanation:
n= pounds of apples
C= total price
$1.67 of apples per pound
Since we dont know the number of pounds of aplles we write n next to $1.67. And C as the total price for n punds of apples.
