So what you do is (2/3)x-9=7. Add 9 to both sides (2/3)x=16. Multiply by reciprocal on both sides 16 x (3/2). 16 x 3 = 48. 48/2=24

A 17 lb dog is ordered to receive 105 mg of Clavamox BID for 14 days. IF Clavamox's concentration is 250mg/5ml, how many oz's of

Studentka2010 [4]

Answer: 1 oz of Clavamox will be sent home with the client.

Step-by-step explanation:

Given, 17lb Dog is ordered to receive 105 mg of Clavamox BID for 14 days.

That means, the dog required 105 mg of Clavamox per day.

So for 14 days, the dog will need $105\ mg \times 14\ days = 1470\ mg$ of Clavamox

Also, the Clavamox concentration is 250 mg/5 ml

Thus, the required amount of Clavamox fotr 14 days = $5 ml \div 250 mg \times 1470 mg = 29.4 \ ml$

Since, 1 oz is 29.5 ml (approximately 29.4 ml.)

So, 1 oz of Clavamox will be sent home with the client.

What is the equation of this line? A: y=-3/2x B: y=2/3x C: y=-2/3x D: y=3/2x

creativ13 [48]

Answer:

b) y = 2/3x

Step-by-step explanation:

Slope (m) formula: $\frac{y_2-y_1}{x_2-x_1}$

I will be using (3,2) and (-3,-2) to find the slope:

$m=\frac{-2-2}{-3-3}\\m=\frac{-4}{-6} \\m = \frac{2}{3}$

$y = mx + b\\y = \frac{2}{3}x+b$

(3,2)

$y = \frac{2}{3}x+b\\\\2 = \frac{2}{3}(3)+b\\\\2 = 2+b\\-2 -2\\\\0=b$

$y=mx+b\\\\y = \frac{2}{3}x+0\\\\y = \frac{2}{3}x$

Hope this helps!

Natasha2012 [34]

Answer:

13.5 mg

Step-by-step explanation:

Here given Cobalt isotope has half life of 5.3 years.

Initial amount is 50 mg.

Given time(10 years) is roughly equals to two half life.

So, after 5.3 year 25 mg of isotope will left further in next half life only around 12.5 mg remains.

Among options 13.5 mg is the best possible
