Answer:
D
Step-by-step explanation:
Because 90/5=18
Answer:
x=-28
Step-by-step explanation:
2x-3x=-1x so if -1x=28 divide both sides by -1 so x= -28
Answer:
Possibly meters or feet/yards.
A walk through a neighborhood would be less than a mile/kilometer but much further than an inch/centimeter.
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
Simplify the radical by breaking the radicand up into a product of known factors in other words take the cube root of 27 then for the exponent 9 you divide by 3 get
3x^3
