Sum of complement angles = 90

<L + <M = 90

3x - 15 + x = 90

4x - 15 = 90

4x = 105

x = 26.25

<L = 3(18.5) - 15

<L = 63.75

Answer

<L = 63.75°

How do you preform the indicated operation 14 - (-10) ?

Gemiola [76]

Answer:

$\Huge \boxed{24}$

Step-by-step explanation:

To solve this problem, first you have to apply the rule of adding numbers from left to right.

$\displaystyle -(-c)=c$

$\displaystyle 14+10$

Then, add numbers from left to right.

$\displaystyle 14+10=24$

As a result, the correct is 24.

An emergency room doctor prescribes a certain pain medication to be delivered through an IV drip. She prescribes 800 mL of the

Keith_Richards [23]

Answer:

The number of drips per minute needed to deliver the medication at the prescribed dosage is 50 drips per minute

Step-by-step explanation:

The given parameters are;

The volume of the prescribed medication to delivered through IV = 800 mL

The duration over which the drug is to be delivered = 8 hours

The rate at which the IV delivers the medication = 30 drips/1 mL

800 mL = 800 × 1 mL

Therefore, the total number of drips in 800 mL= 800 mL × 30 drips/mL = 24,000 drips

The rate at which the drug is delivered = 800 mL/(8 hours) = 100 mL/hr = 100/60 mL/minute = 10/6 mL/minute

The total number of drips in 10/6 mL= 10/6 mL × 30 drips/mL = 50 drips

∴ The rate at which the medication needs to be delivered = 10/6 mL/minute = 50 drips/minute

The number of drips per minute needed to deliver the medication at the prescribed dosage of 800 mL/(8 hours) = 10/6 mL/minute = 50 drips per minute.

galina1969 [7]

Step-by-step explanation:

Given Equation :-

y = -1/2x + 5

On comparing :-

y = mx + c
m = -1/2

Slope of perpendicular line :-

m ' = 2

Using Point slope form :-

y - y1 = m ( x - x1)
y - 0 = 2 ( x -3)
y = 2x - 6
2x - y - 6 = 0
