Answer:

  $93.33 per dose

Step-by-step explanation:

 $1.4×10⁶/(7.5 kg) × (1 kg)/(1000 g) × (0.5 g)/(1 dose)

  = (1.4×10⁶×0.5)/(7.5×10³) $/dose = 700/7.5 $/dose ≈ $93.33/dose

__

Converting dollars per kilogram to dollars per dose involves units conversion from kilograms to doses. We have done it in two steps, first to grams, then to doses.

Using SohCahToa, you’ll find you have the opposite and adjacent, ao, so you’ll use tangent. Opp/adj is x/35 in this situation. You’ll take tan56 • 35 which is 51.9. That should be your answer.

The average of four numbers is 38, and the average of the first two numbers is 42, and the average of the last three numbers is
diamong [38]

Answer:

40

Step-by-step explanation:

let the numbers be a+b+c+d.

the average of 4 numbers is 38

; (a+b+c+d)/4 = 38

(a+b+c+d) = 152 ......equ1

the average of the first two numbers is 42

; (a+b)/2 = 42

(a+b) = 84 ...... equ2

the average of the last three numbers is 36

; (b+c+d)/3 = 36

(b+c+d) = 108 .....equ3

substitute equ3 into equ1

a + 108 = 152

a= 152 - 108

a = 44

input the value of a into equ2

44 + b = 84

b = 40

the second number is 40.

I hope this helps.

Answer:

56 degrees

Step-by-step explanation:

If you look at the m<KLN you can see that it is an acute angle. So, with this being said you have to know that the measure KLN is going to be less than 90 degrees. So you would subtract 180 and 124 and you would get 56 degrees.

I hope this helps :)
