A dose of 4500mg of medication has ordered for a patient. The medication comes in 5g/0.3mL. What volume will you give the patient?
please show conversions
According to the given statement the volume of medicine will give to the patient = 0.27ml.
What specifically is density?A substance's density is defined as its mass per unit volume. The most common symbol for density is, but the Latin letter D is also an option.
What is the significance of density?Density is an important topic because it tells us which compounds will float and which will sink when placed in some kind of liquid. Substances float in general if their density is smaller than the density of the liquid in which they are immersed.
ρ = m/v
ρ = density
m = mass
V = volume
According to the given information:Medicine = 4500mg
The medication comes in 5g/0.3mL
We know that:
mL = mg / 1000
So,
ml = 4500/1000
= 4.5ml
Formula for finding volume = weight/density
= 4.5/(5/.3)
= (4.5 * 0.3)/5
= 0.27ml
According to the given statement the volume will give to the patient = 0.27ml.

The radioactive isotope 14C has a half-life of approximately 5715 years. A piece of ancient charcoal contains only 81% as much of the radioactive carbon as a piece of modern charcoal. How long ago was the tree burned to make the ancient charcoal
Answer:
1758 years
Step-by-step explanation:
0.693/t1/2 = 2.303/t log No/N
t1/2 = half life of the C-14
t= time taken
No= amount of radioactive material originally present
N= amount of isotope after time t.
But N= 0.81 No
0.693/5715= 2.303/t log No/0.81No
0.00012 = 0.211/t
t =0.211 /0.00012
t= 1758 years

n = 1/128000r = -10s = -3t = 15Step-by-step explanation:
You want the simplified form of (5b^1c^-5)^-3(4b^0a^2)^-5.
Rules of exponentsThere are several useful rules of exponents here:
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)
a^-b = 1/(a^b)
ApplicationSimplifying the top-level exponents first, we have ...
[tex](5b^1c^{-5})^{-3}(4b^0a^2)^{-5}=(5^{-3}b^{1(-3)}c^{(-5)(-3)})(4^{-5}b^{0(-5)}a^{2(-5)})\\\\=(5^{-3}4^{-5})a^{-10}b^{-3+0}c^{15}=\dfrac{1}{5^34^5}a^{-10}b^{-3}c^{15}=\boxed{\dfrac{1}{128000}a^{-10}b^{-3}c^{15}}[/tex]
In terms of answer requirements:
n = 1/128000
r = -10

The sum of the digits of a two-digit number is 12. If the digits are reversed, the new number is
54 less than the original number. Find the original number.
Answer:
93
Step-by-step explanation:
Let the digit in tens place be 'x' & digit in ones place be 'y'.
So , the original number = [tex]10x+y[/tex]
According to the question , [tex]x+y=12[/tex]......... .eqn(1)
When digits are interchanged ,
The new number formed = [tex]10y+x[/tex]
According to the question , [tex]10y+x=10x+y-54[/tex] ............ eqn(2)
Solving eqn(2) further ,
[tex]10y+x=10x+y-54\\=>10x-x-10y+y=54\\=>9x-9y=54\\=>9(x-y)=54\\=>x-y=\frac{54}{9}=6.......... eqn(3)[/tex]
Adding eqn(1) and eqn(3) ,
[tex](x+y)+(x-y)=12+6\\=>x+y+x-y=18\\=>2x=18\\=>x=\frac{18}{2} =9[/tex]
Putting the value of x in eqn(1),
[tex]9+y=12\\=>y=12-9=3[/tex]
∴ Original number = 93
How much fertilizer containing 30% nitrogen should be mixed with a fertilizer containing 10% nitrogen to get 10L of a fertilizer containing 12% nitrogen?
Answer:
1L of 30% fertilizer and 9L of 10% fertilizer
Step-by-step explanation:
Let x = the amount of fertilizer containing 30% nitrogen.
Let y = the amount of fertilizer containing 10% nitrogen
x + y = 10 because the two fertilizers together will be 10L
0.3x will be the amount of nitrogen in the 30% nitrogen fertilizer, and 0.1y will be the amount of nitrogen in the 10% fertilizer. If you add those together, you will get 12% of the nitrogen in the 10L mixture. This makes this equation:
0.3x + 0.1y = 0.12(10)
0.3x + 0.1y = 1.2
Now we have our two equations.
x + y = 10
0.3x + 0.1y = 1.2
We can use substitution to solve this system of equations.
x = 10 - y
Substituting this into the second equation, we have:
0.3(10-y) + 0.1y = 1.2
3 - 0.3y + 0.1y = 1.2
3 - 0.2y = 1.2
1.8 = 0.2y
9 = y
10 - 9 = 1L
There will be 9L of 10% nitrogen fertilizer and 1L of 30% nitrogen fertilizer.
Jim has 3 pairs of pants
and 2 shirts. How many
different ways can he
dress?
Answer:
2 to 5 different ways
Step-by-step explanation:
Answer:
12 different ways he can dress
Step-by-step explanation:
Let The Pant be A and Shirt be B
So, we have 3 pair of pants i.e., 6 Pants
Here, We assumed that the pant be A then 6 pants be
A₁ A₂ A₃ A₄ A₅ A₆
Now, For Shirts
We have 2 Shirts
But we assumed that the Shirt be B then 2 Shirts be
B₁ B₂
Then, We will make pair of A and B
A₁ = B₁
A₂ = B₁
A₃ = B₁
A₄ = B₁
A₅ = B₁
A₆ = B₁
A₁ = B₂
A₂ = B₂
A₃ = B₂
A₄ = B₂
A₅ = B₂
A₆ = B₂
Thus, 12 different ways he can dress

At the movie theatre, child admission is $5.20 and adult admission is $8.70. On Sunday, 134 tickets were sold for a total sales of $885.80. How many adult
tickets were sold that day?
Number of adult tickets that were sold that day is 54.
Given,
Cost of child ticket = $5.20
Cost of adult ticket = $8.70
Total sales of tickets = $885.80
Let the number of child tickets sold on that day be x
Let the number of adult tickets sold on that day be y
Total number of tickets sold on that day = 134
Using the above data, we can draw relations between the given variables and make two equations. Solving the two equations for the two variables will give the answer.
Eq 1 :
5.20x + 8.70y = 885.80
Eq 2 :
x + y = 134
These two equations can be solved using the elimination method.
Multiply Eq 2 with 8.70.
=> 8.70x + 8.70y = 1165.8 - Eq 3
Substract Eq 3 from Eq1 to eliminate the variable y and find the value of variable x
5.20x + 8.70y = 885.80
- 8.70x - 8.70y = - 1165.8
______________________
- 3.5x + 0 = -280
=> 3.5x = 280
=> x = 80
Substituting the value of x in Eq 2
=> x + y = 134
=> 80 + y = 134
=> y = 134 - 80
=> y = 54
Therefore, we get the number of child tickets and adult tickets sold that day as 80 and 54, respectively.

Esther bought 4 items.
The prices of the items are given below. Drag items to each box to show what each person could have bought.
So I think I had this for Imagine Math, so here is what I got :D;
Franco (6 items): 6 notebooks = 1.89+1.89+1.89+1.89+1.89+1.89= 11.34
