D. 8°
Explanation: A triangle is always 180° and we know of two points is 50° and 80°, the other must be 60, the 60° is cut in half so if it’s 30° the other side must be thirty. DBC Is 30+50
Answer:
y= -1/2 + 1
Step-by-step explanation:
It starts at +1 which is the B in y=mx+b. B is where a point touches the y-axis.
starting at a point: (-2,2), it goes down 1, and right 2. which now the slope is -1/2 because it is going down.
Answer:
h = 1/616 ≈.002 cm
Step-by-step explanation:
V of a cylinder = Area of the circle · height of the cylinder
A of the circle = π·r² = π·(d/2)² = (22/7)·(28/2)² = 616 cm³
If the V of the cylinder = 1 liter and the Area of the circle = 616 cm³ then
What is the height of the cylinder?
V of a cylinder = Area of the circle · height of the cylinder
V of a cylinder / Area of the circle = height of the cylinder
1/616 = height of the cylinder
Height of the cylinder that is lowered when 1 liter of water is drawn is
h = 1/616 ≈.002 cm
