Answer 1

40) D

41) -56.33

Explanation:

40)

Equation #1) 1 centimeter = 2.5 meters on the drawing

Equation #2) Length of the cafeteria on the drawing = 12.25 cm

Actual length:

Multiply both sides of equation #1 by 12.25 to get the actual length of the cafeteria

1(12.25) = 2.5(12.25)

12.25 cm = 30.625 meters

D

41)

`(0.5\left(8\ +\ 3.2\right))/(-0.1)+\ (3)/(\left(-2.7\ -\ 6.3\right))`

Start with multiplication inside the parenthesis

`(4\ +\ 1.6)/(-0.1)+\ (3)/(\left(-2.7\ -\ 6.3\right))`

Add/Subtract

`(5.6)/(-0.1)+\ (3)/(-9)`

Simplify

`-56+\left(-0.33\right)`

`-56 - 0.33`

`-56.33`
