Solution:
Weight of person = 179 lbs
As given person needs IV Drip in m L.
Also,→ 10 mg = 2 m L
Now, you must remember , → 1 lbs = 0.453 Kg (approx)
→179 lbs = 179 × 0.453 Kg = 78.47 Kg (approx)
The person needs at least 60 mg for each Kg they weigh.
⇒ 1 Kg → 60 mg
⇒ 78.47 × 1 Kg → 78.47 × 60 mg
⇒ 78.47 Kg → 4708.2 mg
Also, 10 mg → 2 m L
⇒ 1 mg → 
m L
⇒ 4708 . 2 mg → 
m L
⇒ 4708 . 2 mg → 941. 64 ml
Answer:
a) x = 62
b) x = 33
Step-by-step explanation:
Hi there!
a) Let´s write the equation:
√(2x-3) = 11
Square both sides
2x - 3 = 121
add 3 to both sides of the equation
2x = 124
divide by 2 both sides
x = 62
Let´s check:
√(2x-3) = 11
x = 62
√(2(62)-3) = 11
√(124-3) = 11
√121 = 11
11 = 11
x = 62 satisfies the equation
b) Let´s write the equation:
∛(6 - x) = -3
Cube both sides
6 - x = -27
subtract 6 to both sides
-x = -27 - 6
-x = -33
divide by -1 both sides
x = 33
Now, let´s check the result:
∛(6 - x) = -3
x = 33
∛(6 - 33) = -3
∛(-27) = -3
-3 = -3
x = 33 satisfies the equation
Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.
Let me know if this helps!
Answer:
c=1
Step-by-step explanation:
Simplifying
3 + 2c = 5
Solving
3 + 2c = 5
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2c = 5 + -3
Combine like terms: 3 + -3 = 0
0 + 2c = 5 + -3
2c = 5 + -3
Combine like terms: 5 + -3 = 2
2c = 2
Divide each side by '2'.
c = 1
Simplifying
c = 1
9x^2 - y^2 = 1
a.) 18x - 2y dy/dx = 0
2y dy/dx = 18x
dy/dx = 9x/y
b.) y^2 = 9x^2 - 1
y = √(9x^2 - 1)
y' = 9x / √(9x^2 - 1)
c.) substituting y = √(9x^2 - 1) into solution for part a gives
dy/dx = 9x / √(9x^2 - 1)
Thus the two solutions are consistent.
