Answer:
2 cubes are red, 6 are blue, the rest are yellow so 8
Step-by-step explanation:
Given that the concentration has been modeled by the formula:
C(t)=50t/(t^2+25)
where:
t is time in hours.
The concentration after 5 hours will be given by:
t= 5 hours
plugging the value in the equation we get:
C(5)=(50(5))/(5^2+25)
simplifying the above we get:
C(5)=250/(50)=5 mg/dl
Answer: 5 mg/dl
Answer:
A
Step-by-step explanation:
The formula for this type of interest is 
, where A is the total amount, P is the initial investment, x is the interest rate, n is the amount of times that the investment is compounded a year, and t is the amount of years. Plugging in the numbers given, you get:
Now, she invests this into a new account, and you can set up the following equation:
, or option A.

Answer:
Volume=2521.91 mm³
Step-by-step explanation:
d=13, r=13/2=6.5, h=19
volume=πr²h
=π(6.5)²×19
=<u>2521.91 mm³</u>
<u>hope it helps</u>
<u>have a great day!!</u>
Volume = Area x Height. We are given Volume and Area, so plug in and solve for Height (Height = Volume/Area)
18in^3 = 4.5 in^2 x Height (divide both sides by 4.5) -> 4in = Height
