A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
Answer:
18.85 inches³
Step-by-step explanation:
Given:
Height of the cylindrical glass, h = 8 inches
Diameter of the cylindrical glass = 2 inches
or
Radius of the cylindrical glass, r = 1 inches
Now,
the volume of the cylindrical glass = πr²h
or
the volume of the cylindrical glass = π × 1² × 8 = 8π inches³
therefore, the volume of tea in the cylindrical glass = 8π inches³
Now,
Lily drinks only 3/4 of her tea
therefore,
the volume of tea Lily drunk =
or
the volume of tea Lily drunk = 18.85 inches³
Answer:
75
Step-by-step explanation:
mean = average so add up all your numbers, then divide by the amount of numbers so
46 + 56 + 64 + 64 + 72 + 76 + 77 + 82 + 94 + 96 + 99 = 826
826 ÷ 11 = 75.09 (about)
The equation of the circle with a center (-5, -6) and a radius of 5 is (x + 5)² + (y + 6)² = 25.
<h3>How to Write the Equation of a Circle?</h3>
The standard equation for writing the equation of a circle is: (x - h)² + (y - k)² = r².
Given the following:
Center (-5, -6) = (h, k)
Radius = 5 = r
Plug in the values into the formula
(x + 5)² + (y + 6)² = 5²
(x + 5)² + (y + 6)² = 25
