Answer:
The amount remaining after 24 hours is 17.5 milligrams.
Step-by-step explanation:
The rate of decay is proportional to the amount of the substance present at a time
The equation is
Rate=k*amount remaining at(time)
Where k = constant of proportionality.
So we don't know the value of k, let's find it.
7= k(70)(6)
K= 1/60
Amount remaining after 24 hours
7= 1/60 * x* (24)
(60*7)/24= x
17.5 = x
The amount remaining after 24 hours is 17.5 milligrams.
The correct answer would be B because it is shaded below , it also has a negative slope
1.) Solving for x: x= -(3y/2) +5
solving for y= -(2x/3)+3 1/3
2.)solving for x: x= 10y/3+5
solving for y: y=3x/10 - 1 1/2

Answer :- Yes the two triangles are similar because there are two pairs of congruent corresponding angles.
Explanation:-
In Δ ABC
∠A=30° , ∠C=65 °
By angle sum property of triangle
∠A + ∠B + ∠C= 180°
⇒∠B= 180°-∠A-∠C=180°-30°-65°=85°
⇒∠B=85°
Now in ΔABC and ΔDEF
∠A=∠D=30° and ∠B=∠E=85°
⇒ there are two pairs of congruent corresponding angles.
So by AA-similarity criteria
ΔABC ≈ ΔDEF
Answer:I think your Answer would be x=14 but I am not sure.
Step-by-step explanation:
2log 10 (x+86)=4
Determine the defined
2log 10 (x+86)=4,x >-86
Divide both sides by 2
log 10 (x+86)=2
Solve by converting the logarithm into exponential form
x+86=10 2
Evaluate the power
x+86=100
Move constant to the right
x=100-86
Subtract the numbers
x=14,x>-86
Check if the solution is in the defined range
SOLUTION
X=14
