Acylindrical oil tank holds 510 gallons when it is filled to its full
height of 8.0 ft. when it contains oil to a height of 3 ft 9 in, how
many gallons are in the tank?
298.2 gal
302.4 gal
277.9 gal

239.1 gal

Step-by-step explanation:

8 ft = (12 * 8) = 96 inches

3 ft 9 in = (12 * 3) + 9 = 45 inches

510 gallons to 96 inches = x gallons to 45 inches

510 / 96 = x / 45cross multiply because this is a proportion

(96)(x) = (510)(45)

96x = 22950

x = 22950 / 96

x = 239.0625 rounds to 239.1 gallons <===

sorry, i can't understand your question. will later if you describe more clearly!

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
