Answer: OPTION B

Step-by-step explanation:

You have the following expresion:

(\frac{3}{4}\sqrt{15})(16\sqrt{5})

Mulitply them, then:

=12\sqrt{75}

Now, descompose the number inside the square root into it primes factor to simplify the expression:

75=5*5*3=5²*3

Substitute:

=12\sqrt{5^2*3}

Simplify. Then, you obtain:

=12*5\sqrt{3}

=60\sqrt{3}

Sophia has an ear infection. The doctor prescribes a course of antibiotics. Sophia is told to take 500 mg doses of the antibioti
olganol [36]

Answer:

Dosage= 500 mg

Frequency= twice a day (every 12 hours)

Duration= 10 days

Number of dosage= 10*2= 20

residual drug amount after each dosage= 4.5%

We can build an equation to calculate residual drug amount:

  • d= 500*(4.5/100)*t= 22.5t, where d- is residual drug, t is number of dosage
  • After first dose residual drug amount is: d= 500*0.045= 22.5 mg
  • After second dose: d= 22.5*2= 45 mg

As per the equation, the higher the t, the greater the residual drug amount in the body.

Maximum drug will be in the body:

  • d= 20*22.5= 450 mg at the end of 10 days

Maximum drug will be in the body right after the last dose, when the amount will be:

  • 500+19*22.5= 927.5 mg

goldenfox [79]

Answer:

243 ways

Step-by-step explanation:

Calculating the number of posible outcomes:

We have n trials.

Each trial has m possible outcomes.

The total number of outcomes is:

T = m^{n}

In this question:

5 questions, that is, 5 trials, so n = 5

Each question has 3 options(True, false or unanswered). So m = 3

How many ways?

T = 3^{5} = 243
