Answer:
y=3x-1 = x=1/3
Step-by-step explanation:
y=3x-1
to find the 0-intercept at x, underline y = 0
0=3x-1
move the variable to the left side and change its sign
-3x=-1
divide both sides of the equation by -3
x=1/3
Answer:
849.92
Step-by-step explanation:
Triangle = ½×32×28 = 448
Radius = 32/2 = 16
Semicircle = ½×3.14×16² = 401.92
Total area = 448 + 401.92
= 849.92 m³

Answer:
12,600mg per 21 days
Step-by-step explanation:
200mg three times a day → (200mg)(3) = 600mg per a day
21 days → (21)(600mg) = 12,600mg per 21 days
Density=mass / volume ⇒ mass=density x volume.
Data:
density=3.5 g/cm³
volume=7.0 cm³
mass=(3.5 g/cm³)(7.0 cm³)=24.5 cm³
