Answer: 28 gallons of paint needed to paint 16 classrooms.
Step-by-step explanation:
As 7 gallons Paint 4 classrooms so if we need to paint 16 classrooms which four times 4 classrooms so 7*4=28 gallons will be needed to paint 16 classrooms
tan = opp/adj
x = 13(tan 45)
x = 13
//
a² + b² = c²
13² + 13² = 338²
square root of 338 is not a rational number so turn into mixed radical.
there are (1/6)/(1/3) one-third in one sixth
that means
no. of one-third is 1/2
