2)Two rectangles were used to form the following figure. The dimensions of the interior angle are 8 and 13 inches. The dimensions of the exterior angle are 9 and 15 inches.What is the area of the shaded region in square inches?
Music fractions are kinda like math.
In 4/4 time a quarter note (indicated by the denominator of 4) gets one beat
In 6/4, the numerator indicates 6 beats per bar
In the unusual 4/8 time, the denominator of 8 indicates an eighth note gets one beat
The volume is (area of cross-section) x (length) .
-- The cross-section is a triangle. The area of a triangle is
Area = (1/2) (base) (height) .
In this one, the base is 9/4 m and the height is 3-1/3 m .
Area = (1/2) (9/4 m) (3-1/3 m)
Area = (1/2) (9/4) (10/3)
Area = 90/24 m² .
-- Volume = (area of cross-section) x (length)
Volume = (90/24 m²) x (7-1/3 m)
Volume = (90/24) x (22/3) m³
Volume = (1,980 / 72) m³
Volume = 27.5 m³
