<u>Trigonometry</u>

  • [Right Triangles Only] SOHCAHTOA  
  • [Right Triangles Only] sinθ = opposite over hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

Angle θ = ∠R

Opposite Leg of ∠R = 10√3

Hypotenuse = 20

<u>Step 2: Solve</u>

  1. Substitute in variables [sine]:                                                                         \displaystyle sin(R^\circ) = \frac{10\sqrt{3}}{20}
  2. [Equality Property] Trig inverse:                                                                    \displaystyle R^\circ = sin^{-1}(\frac{10\sqrt{3}}{20})
  3. Evaluate trig:                                                                                                   \displaystyle R = 60^\circ

A 27​% solution ​( 27mg per 100 mL of​ solution) is given intravenously. Suppose a total of 1,36 L of the solution is given over
a_sh-v [17]

Answer:

Step-by-step explanation:

a.

(1.36 L)/(10 hr) = (0.136 L)/(hr)

Flow rate = (0.136 L)/(hr) × (1000 mL)/L = (136 mL)/(hr)

136 mL × (27 mg)/(100 mL) = 36.72 mg

Delivery rate = (36.72 mg)/(hr)

b.

(136 mL)/(hr) × (13 gtt)/(mL) = (1868 gtt)/(hr)

c.

10 hr × (36.72 mg)/)hr) = 367.2 mg

serious [3.7K]

Answer:

vertex: (4,-6), y= -14

Step-by-step explanation:

vertex can be derived from this formula

The denominator of a fraction is 5 more than the numerator. if both the numerator and denominator are increased by 3, the the re
g100num [7]

Let's put it into perspective.

x/(x+5)

If increase by 3:

(x+3)/(x+8) = 3/4

Cross multiply.

4(x+3)=3(x+8)

4x+12 =3x+24

Solve algebraically.

4x-3x = 24-12

x = 12

Therefore, original fraction is:

12/17
