First, you need to convert all units to calculate what dose the doctor ordered.
1 dram = 4 mL
So, it must be given 4 mL of medication
1 cc = 1 mL
So, if t<span>he vial states that there is 1 mg in 1 cc </span>, that means the concentration is 1 mg in 1 mL or, 1 mg/mL.
Now, we need to calculate what is the dose of medication in 4 mL:
1 mg is in 1 mL, how many mg is in 4 mL:
1 mg : 1 mL = x : 4 mL
Crossing the products:
x · 1 = 1 mg · 4
⇒ x = 4 mg
2-x/x/3=-2
what are you trying to figure out
Answer:
n = -31.5
Step-by-step explanation:
let 'n' = the number
n/-1.5 = 21
to solve for 'n', multiply each side by -1.5 to get:
n = -31.5
One way to approach this is to find (g o f)(x) first and then to replace x by -7:
g( f(x) ) = (x^2+6) + 8/(x^2+6)
Now replace x with -7. We get: ( g o f )(-7) = 49+6+8 / (49+6), or
= 55 + 8 / 55, or 55 8/55 (ans.)
Answer:
$1,326
Step-by-step explanation:
You are going to want to use the simple interest formula for this.
<em>I = interest amount
</em>
<em>P = principal amount
</em>
<em>r = interest rate</em>
<em>t = time</em>
First, change 1.7% into its decimal form:
1.7% -> 
-> 0.017
Next plug in the values into the equation:
After three years, he must repay $1,326.
