Solve ench of the following problems by setting up a direct proportion. (a) Painting If I gal of paint covers 825 sq R, how much paint is needed to cover
2640 sq 12
(b) Transportation A diesel truck was driven 273 miles on 42 gal of fuel. How
much fuel is needed for a trip of 600 miles? (Round to the nearest gallon)
(e) Industrial Technology A cylindrical oil tank holds 450 gal when it is filled to
its full height of 8 A. When it contains oil to a height of 2 A 4 in., how many
gallons of oil are in the tank?
(a) A direct proportion the more paint, the greater the area that can be covered:
1 gal 825 sq ft
2640 sq ft

step-by-step explanation:

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x
