How many mL of medication are needed to last 10 days if the dose of medication is 2.5 tsp TID (three times a day)?
rjkz [21]

Answer:

369.7 mL of medication

Step-by-step explanation:

How many mL of medication are needed to last 10 days if the dose of medication is 2.5 tsp TID (three times a day)?

From the above question,

The dosage of the medication =

2.5 tsp 3 times a day

= 2.5 × 3 = 7.5 tsp per day.

Since

1 day = 7.5 tsp

10 days = x tsp

Cross Multiply

x = 10 × 7.5 tsp

x = 75 tsp of medication for 10 days.

Step 2

It is important to note that:

1 tsp = 4.929 mL

75 tsp = x mL

Cross Multiply

x = 75 × 4.929 mL

x = 369.669 mL of medication

Approximately = 369.7 mL of medication

fgiga [73]

Answer:

<u>$15,000</u> is the amount to spend on marketing in the month of March.

Step-by-step explanation:

Given:

You have a monthly budget percentage of 5% for marketing.

Your projected sales for the month of March are $300,000.

Now, to find the amount spend on marketing:

Rate of marketing = 5%.

Projected sales for the month of March = $300,000.

Now, to get the amount spend on marketing in March:

<u><em>5% of $300,000.</em></u>

=\frac{5}{100} \times 300,000

=0.05\times 300,000

=15,000.

Therefore, $15,000 is the amount to spend on marketing in the month of March.

Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x
anyanavicka [17]

Answer:

x = 7.2

Step-by-step explanation:

Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x and 1.7.

Now. the distance between - 3.8 and x will be (x + 3.8) and the distance between x and 1.7 will be (x - 1.7) {Since x is a positive number}

(Assuming x is greater than 1.7}

Given that, x + 3.8 = 2(x - 1.7)

⇒ x + 3.8 = 2x - 3.4

⇒ x = 7.2 (Answer)
