What's the problem? I don't see the equation.
First, you much find out how many houses are deliverd in 1 hour.
130/2.5=52
So 52 houses are delivered in 1 hour. Now, divide that by 312.
312/52=6
It would take 6 hours to deliver 312 houses.
The answer is 4 3/8 boxes because 1 3/4 x 2 1/2 ＝ 4 3/8.
Answer:
x=12
Step-by-step explanation:
If the triangles are similar:
x/8=18/12
x/8=1.5
x=12
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
