Answer:
50.80 mL/hr
Step-by-step explanation:
The prescription is using kg for the mass unit while the weight use pounds. We have to change the weight unit into kilograms to calculate the dose of the IV infusion. The type of solution should not have any influence on the calculation.
If one kilogram equal to 0.0.453592 pounds, the calculation will be:
14 pounds * (0.0.453592 kg/ pounds) * 8mL/kg/hr=
6.35 kg * 8mL/kg/hr= 50.80 mL/hr
He will need 180 square tiles because 12 inches is a foot. So 15 feet times 12 feet is 180 feet of space that you need to cover with one foot tiles :P
Answer:
B
Step-by-step explanation:
Its not A because when you plug in 0.6 in for P it gives you 6.6=1.8. (0.6)+6=1.8
Its B because when you plug in 0.6 in for P it gives you 6=6.
10(0.6)=6
Its not C because when you plug in 0.6 in for P it gives you 0.36=10.
0.6(0.6)=10
Its not D because when you plug in 0.6 in for P it gives you -0.4=0.4.
(0.6)-1=0.4
Answer:
Incorrect
The correct answer is 1/6
Step-by-step explanation:
Freddy is incorrect. You are not supposed to subract the denominators. When you are solving the equation you have to find a common denominator. You can only subtract the numerator, and the denominator is the same.
Find the LCM. The LCM in this case is 6.

Remember, only subtract the numerators. The denominator will still be 6.

1/6 is the correct answer. I hope this helps you!
Answer:
Step-by-step explanation:
- 10x² - 7ax + (a + 2) (a - 5) =
- 10x² - 7ax + a² - 3a - 10
Factorize by finding the roots
<u>Find the discriminant:</u>
- D = b² - 4ac
- D = (-7a)² - 4*10*(a² - 3a - 10) =
- 49a² - 40a² + 120a + 400 =
- 9a² + 120a + 400 =
- (3a + 20)²
<u>Find the roots:</u>
- x = (- b ± √D)/2a = (7a ± (3a + 20)) / 20
- x₁ = (7a + 3a + 20) / 20 = (10a + 20) / 20 = (a + 2) / 2
- x₂ = (7a - 3a - 20) / 20 = (4a - 20) / 20 = (a - 5) / 5
<u>Factorize the expression:</u>
- 10x² - 7ax + a² - 3a - 10 =
- 10 (x - x₁)(x - x₂) =
- 10[x - (a + 2)/2][[x - (a - 5)/5] =
- (2x - a - 2)(5x - a + 5)
====================================================
<u>You would also try a shorter but more difficult way:</u>
- 10x² - 7ax + (a + 2) (a - 5) =
- 2x*5x - 2ax + 10x - 5ax - 10x + (a + 2) (a - 5) =
- 2x*5x - 2x(a - 5) - 5x(a + 2) + (a + 2) (a - 5) =
- 2x(5x - (a - 5)) - (a + 2)(5x - (a - 5)) =
- (5x - a + 5)(2x - a - 2)
